You can use tungsten inert gas (TIG) and metal inert gas (MIG) welding to make high-quality joints between different types of metal. Neither option is superior overall, but the unique welding techniques and processes will suit different jobs better. 

MIG welding is generally less complex and penetrates thicker materials more effectively, whereas TIG welding is ideal for precise welds on thinner materials. Explore the similarities and differences between MIG and TIG welding and when to use each type. 

TIG vs. MIG Welding

TIG and MIG welding techniques are similar, but have key distinctions to be aware of before choosing one over the other. Important differences include: 

Cost: MIG welding is faster, so it can be more cost-effective in terms of labor costs and productivity. The machines, parts and the wire required for MIG welding are usually easier to source and less expensive than TIG parts.
Process: While both use arc welding, the process is different, and you need specific welding equipment and tools for each type. This includes the electrodes used, the need for separate welding rods, foot pumps and power sources. 
Weld strength: TIG welds can be stronger because they use a narrower arc for better penetration into the metals. They can also be tougher because they can have fewer defects.
Application: TIG welds use a handheld filler rod, which allows for more accurate joins. However, this means using two hands and a foot pedal. This makes TIG welds better for workbenches and static setups, whereas MIG welding gives you a free hand for awkward joins or for site work.
Ease of use: MIG welding is easier to learn, partly because less equipment is needed, and one hand is always free. 
Precision and aesthetics: For fewer spatters or discolorations, choose TIG welding for less cleanup work. MIG welds can still be done carefully to preserve aesthetics, and you can polish up any blemishes after welding. 
Automation: MIG torches or guns are often compared to hot glue guns, have an automatic arc and can be run continuously. TIG welding requires operators to adjust the amperage to control the heat needed to melt materials.
Gas flow: Depending on the materials, TIG welding can use a lower gas flow rate than MIG welding.
Power source: MIG techniques use direct current (DC) power for stability and can penetrate most metals. TIG can use alternating current (AC) or DC power to suit the type of metals, electric arc and weld pool spatter.

MIG and TIG welding both follow a similar process to arc welding. This involves an electric arc or current that heats up and melts the metals or base materials you want to join together. You can also use filler materials in both MIG and TIG welding to help strengthen the bonds. 

Heating the base materials and filler creates a pool of molten material, which then cools to form a solid, clean joint. The shielding gas protects materials from contamination or oxidation. Both types of welding can be used across different industries, from manufacturing and construction to aerospace and marine.

TIG Welding Process

TIG welding, also known as gas tungsten arc welding (GTAW), uses a non-consumable tungsten electrode to heat up and melt the parent materials and filler materials used to create a joint. 

The foot pedal controls the heat by setting the correct amperage for the materials you’re working on. With the welding electrode in one hand, add the filler material with the other using a welding rod placed into the welding pool. 

The best practice is to use argon as the shielding gas, as it is the most affordable and accessible of inert gases. Argon protects your weld from defects caused by oxygen and nitrogen contamination. 

Benefits and Applications of TIG Welding

TIG welding can be more effective for some applications, including:

Thin metals: TIG welding can be less aggressive on thinner gauge metals, which helps prevent warping or burning through the material. It is also possible to make autogenous welds with no need for filler material. You can use a lap joint weld to join the parent materials together.
Exposed beads: TIG welding can give a better finish for cleaner, more aesthetic welds. This is useful for consumer products or when beads are exposed.
Ferrous and nonferrous Metals: Typically, TIG welds join steels and nonferrous metals, such as aluminum and copper. 
Workshop welding: Outdoor windy conditions can interfere with TIG welds. Instead, TIG welding is better for precision jobs in a workshop environment where the control of the filler rod and foot pedal is more beneficial. 

MIG Welding Process

Also known as gas metal arc welding (GMAW) or wire welding, MIG welding uses a consumable solid wire electrode. The wire acts as both the electrode and the filler material here. Constantly feed the spool of wire through the welding gun into the weld pool, where it is heated, melting the parent material and adding a filler material to help join them together.

You can also use argon as a shield gas for MIG welding, with the option to add carbon dioxide. The added CO2 prevents oxidation and allows for short arc transfer or dip transfer welding, which allows for welding in various positions. 

Benefits and Applications of MIG Welding

MIG welding offers many benefits, including the following:

Suitability for diverse operations: MIG techniques are suited to a wide range of materials, thicknesses and welding positions for when you need versatility in your welding operations. 
Covered welds: When aesthetics are less important, such as in structural applications, MIG welds are durable, and you can paint or cover them if needed.  
Quick production times: MIG welding is efficient and often faster than TIG welding, so you can reduce lead times and labor costs. 
Thicker materials: MIG welding can handle different thicknesses and gauges, but it is more effective for welding thicker materials. This is because MIG offers higher deposition rates and deeper penetration into the materials.
Training new hires: MIG welding is less complex to learn, making it easier for beginner welders to create acceptable welds while maintaining production speed.

High-quality gases and tailored mixtures are critical enablers of research, innovation and manufacturing. The expertise of industrial gas suppliers is increasingly in demand in healthcare, environmental sciences, electronics, food preservation, and more.

Industrial gas blends must meet exact specifications, strict tolerances and guarantee consistency. Selecting the right supplier directly affects the quality of your product, regulatory compliance and operational safety. Understanding how industrial gas blends are made is the first step.

What Are Industrial Gas Blends?

Industrial gas blends are mixtures of gases used in industrial applications. They’re made by combining controlled ratios of different gases. The purpose is to achieve specific properties and performance characteristics that can be applied in industrial processes.

The most common gases used in industrial gas mixing are: 

Nitrogen: Used in food packaging and electronics manufacturing
Oxygen: Applicable in healthcare applications and metal fabrication
Carbon dioxide: Used as a refrigerant or in fire suppression systems and beverage carbonation
Argon: Used when nonreactive atmospheres are required, like electronics manufacturing and arc welding
Helium: Essential in medical imaging and research
Hydrogen: Used for refining and clean energy

Physical Principles

Diffusion, convection and pressure differentials are used to create homogeneous mixtures. The rate of mixing depends on factors like gas viscosity, temperature and the specific mixing method used, which can be mechanical agitation, pressure-based systems or other techniques. 

How gases mix: Manufacturers consider the physical properties of each gas — density (how heavy the gas is), pressure (how tightly packed the gas molecules are) and solubility (how well one gas dissolves in another gas or liquid).
Gas laws: Scientific laws predict the behavior of gases. Dalton’s Law of Partial Pressures states that in a mixture of gases, each gas contributes to the total pressure in proportion to its amount. This helps manufacturers calculate exactly how much of each gas to add to achieve a particular blend.
Uniform mixing: Every part of a gas blend must have the same composition, which is achieved with proper mixing.

Chemical Compatibility

Understanding which gases safely mix helps prevent hazardous chemical reactions and undesirable properties.

Safe combinations: Certain combinations of gases can react chemically and result in dangerous byproducts, loss of blend stability or even explosions.
Material compatibility: Some gases can corrode metals or degrade rubber seals, leading to leaks or contamination. It’s crucial that cylinders and valves used to store and transport gas blends are made from materials that won’t react with the gases inside.

Purity and Precision

Gas purity and composition require understanding gas behavior, advanced mixing technologies and rigorous quality control measures.

Importance of purity: Tiny impurities can affect gas blend performance, particularly in sensitive applications like medical treatments or scientific research, where they can cause inaccurate results or health risks. 
Blending precision: Mixtures must be precise, down to parts per million or even parts per billion. Getting this level of accuracy requires advanced equipment and strict quality control.

Key Methods of Gas Blending

Several dynamic blending systems, including gravimetric, volumetric and continuous blending, are used to achieve highly accurate gas mixtures. The method chosen depends on the specific application and desired blend accuracy.

Gravimetric Blending

Gravimetric blending involves mixing materials based on their weight and establishing precise and consistent proportions. Gases are measured and added by weight using extremely sensitive scales. This technique has many advantages, including the highest accuracy and compliance with ISO 6142. It’s ideal for specialty and calibration gases.

Each ingredient is weighed into the mixing chamber using load cells and dispensing valves, where the weight is precisely measured before blending. The total mass is calculated to achieve the desired concentration, and the blend is homogenized and analyzed for quality.

Volumetric Blending

This approach controls the volume of each gas to achieve the desired mixture. Gases are measured by volume, often using pressure and temperature data. Mass flow controllers are used to regulate the flow rate of each gas, ensuring the desired volumetric proportions in the final mixture.

The volumetric blending method is faster than gravimetric blending and is suitable for less critical blends. It’s common for large-scale or continuous production. However, volumetric blending is less precise than gravimetric, especially for low-concentration components.

Dynamic Blending

This is the process of creating breathing gas mixtures by continuously mixing the gases in the mixture. Gases are mixed in real time using mass flow controllers and automated systems. Mass flow controllers regulate each gas stream. Programmable logic controllers monitor and adjust flows for accuracy, and in-line static mixers ensure homogeneity.

Continuous blending allows for on-demand blending and rapid recipe changes. Dynamic blending systems are used in processes that demand a continuous supply of gas, like manufacturing lines.

Advanced Technologies in Gas Blend Manufacturing

To ensure gases are mixed together safely, accurately and consistently, industrial gas manufacturers use advanced technologies that include specialized mixing devices, automated control systems and real-time quality monitoring tools.

Manufacturers can mix gases precisely for a range of industrial, medical and scientific applications using equipment like static and helical mixers and automated blending systems with sensors and software. These innovations help ensure every gas mixture meets strict quality and safety standards, giving customers confidence in the products they buy.

Static Mixers

Static mixers are tubes or pipes with special shapes or barriers inside. As gases flow through, the internal elements create turbulence, swirling and mixing the gases together. There are no moving parts in these mixers, making them low-maintenance. They work for mixing two or more gases (gas-gas) or a gas with a liquid (gas-liquid).

Helical Mixers

Helical mixers have twisted, spiral-shaped pieces inside a pipe. The spiral shape forces the gases to twist and turn as they move through the pipe, thoroughly mixing them. Helical mixers are especially good for mixing gases as they travel through long pipelines.

These mixers blend gases for a wide range of industries. They’re used in applications that demand gentle but effective mixing, especially with thicker and more flow-resistant materials.

Automated Blending Systems

These are high-tech systems that use machines and computers for industrial gas mixing. Mass flow controllers measure and control exactly how much of each gas goes into the blend. Sensors check the flow and composition of the gases in real time. Software handles the whole process, making sure the blend is always correct. A touchscreen or computer allows operators to set the blend “recipe,” watch the process and make adjustments if needed.

Automated systems make blending more accurate, consistent and easy to monitor. They often create custom gas mixtures for processes that require precise and reliable gas mixtures, such as medical applications and research, diving, food packaging, and welding. 

Quality Monitoring

Continuous checking ensures a gas blend is always correct. Real-time sensors instantly detect if the blend is off or if there’s a problem with flow. If something goes wrong, alarms alert staff instantly. The quality monitoring system records all measurements and actions, so there’s a record for quality checks and regulatory compliance.

Quality Assurance, Standards and Certification

Safety, reliability and compliance with standards are critical in the manufacture of industrial gas blends. Strict protocols safeguard against contamination and specify consistent gas compositions.

Analytical Methods

Industrial gas manufacturers use advanced techniques, such as gas chromatography, to verify the exact composition of every gas blend. The results are compared against trusted reference standards to ensure each blend meets precise specifications.

Standards and Certification

Each batch is accompanied by a certificate of analysis, which details the concentrations, tolerances and full traceability of the blend. Compliance with standards like ISO 6142 for gravimetric blending and industry best practices like the Compressed Gas Association’s American National Standards program supports reliability and consistency.

Traceability

Industrial gas manufacturers must follow strict protocols to achieve the highest levels of safety and quality. To support regulatory compliance and customer audits, all measurements and calibrations are fully traceable to national or international standards, such as those of the National Institute of Standards and Technology’s Standard Reference Material program.

Applications and Uses of Specific Industrial Gas Blends

Every industry and application has its own needs when it comes to gas mixtures. For example, electronics manufacturing might require extremely pure gases, while welding or food packaging may need specific combinations for the best results.

Blended gas manufacturers can work directly with customers to understand their requirements and design mixtures that deliver the right performance, safety and efficiency for each job.

Common Applications

Industrial gas mixing is crucial in many industries, from aerospace to recreational underwater diving. Examples include:

Food and beverage: Gas blends help preserve perishable goods within modified atmosphere packaging by inhibiting oxidation and spoilage. They’re used to flash-freeze food items for transportation and storage and carbonize soda and beer.
Industrial sector: Welding, cutting and brazing processes commonly use a variety of inert and active gas mixtures, depending on the thickness and composition of the metal.

Natural gas vehicles (NGVs) use natural gas as an alternative fuel to traditional gasoline and diesel. These alternative fuel vehicles have been around since the 1930s but were overtaken by gasoline and diesel-powered vehicles. With the growing need for sustainable solutions, NGVs are experiencing a resurgence.

Today, the global presence of natural gas vehicles is over 23 million, while the United States has over 135,000 NGVs on its roads. This guide highlights how these alternative vehicles work, some of their benefits, challenges and available infrastructure.

How Natural Gas Vehicles Work

Natural gas vehicles work the same way gasoline vehicles do since they have spark ignition combustion engines. In these engines, fuel mixed with air enters the combustion chamber, where it’s compressed and ignited by a spark plug. Compressed natural gas (CNG), which is typically stored in a fuel cylinder at the back or under the vehicle, flows through a high-pressure fuel line into a pressure regulator that reduces the pressure to match the engine’s system before the fuel enters the combustion chamber.

Once ignited, the expansion of CNG inside the combustion chamber forces the piston to move, generating the torque needed for the vehicle to operate.

Types of Natural Gas Used

Natural gas is present in diverse forms. NGVs are designed to run on distinct versions of these gases. Here are the different types of natural gas and their uses in NGVs:

Compressed natural gas (CNG): This gaseous fuel is composed mainly of methane and compressed to a high pressure of about 3,000 to 3,600 psi, making it less than 1% of its volume. CNG is the most preferred natural gas fuel for NGVs.
Liquefied natural gas (LNG): This is natural gas cooled into liquid form at about minus 260 degrees Fahrenheit (minus 161.5 degrees Celsius). In this state, LNG offers higher energy density than CNG and is best suited for heavy-duty vehicles like long-distance trucks.
Adsorbed natural gas (ANG): This is natural gas stored in a porous adsorbent system and is designed to counter the storage limitations of CNG and LNG.

Components of a Natural Gas Vehicle

Natural gas vehicles have various components that work together for the vehicle to operate. Here are the key components of NGVs:

Fuel tank: Like gasoline or diesel tasks, these tanks store the vehicle’s fuel, which in this case is compressed natural gas.
Fuel line: A tube, metallic or otherwise, that allows the flow of fuel from the fuel tank to the fuel system.
Pressure regulator: A device directly below the fuel tank that lowers CNG pressure to a level compatible with the engine’s fuel injection system.
Natural gas fuel filter: A filtration system that eliminates contaminants and byproducts from CNG to prevent damage or blockage inside the engine system.
Fuel injection: A fuel system component responsible for injecting fuel into the combustion chamber.
Internal combustion: Engine configuration where fuel is combined with air in a combustion chamber or intake manifold and ignited by a spark plug.
Exhaust system: A system designed to flush exhaust gases from the engine through the tailpipe.
Transmission: A medium that transmits power from the engine to the wheels.
Electronic control module: A control unit that manages engine performance. It monitors and regulates fuel injection, ignition timing and other key engine processes. 
Battery: Like other fuel-based vehicles, NGVs also have batteries that supply electricity to kick-start the engine and power other electronics.

Benefits of Natural Gas Vehicles

Natural gases, whether renewable or conventional, have unique qualities over gasoline and diesel. It’s these qualities that make up the benefits of NGVs such as:

Fuel Efficiency

Alternative fuels and energy efficiency are key when considering NGVs. While these vehicles are similar to their diesel and gasoline-powered counterparts in terms of power, speed and acceleration, they may offer better fuel economy. The reason is that CNG engines have a higher pump octane number compared to gasoline.

Environmental Impact

Natural gas is one of the cleanest fuels available, making NGVs better for the environment than diesel and gasoline vehicles. When fueling NVGs, these gases produce 20% fewer greenhouse emissions. Additionally, NVGs can’t release evaporative emissions since CNG fuel systems are sealed.

Cost Savings

Generally, NGVs are more cost-effective than vehicles powered by traditional fuel, and that is due to the low retail price and stability of natural gas. The U.S. has vast reserves of natural gas, allowing domestic price-setting and eliminating market fluctuations common with crude oil. As of October 2024, the retail price of CNG was lower than that of gasoline and diesel.

Challenges of Using NGVs

One of the attractive aspects of natural gas vehicles and their functioning is their great potential to reduce carbon emissions. However, NGVs have challenges holding back their adoption, such as:

High upfront costs: NGVs are still more expensive upfront because their systems cost more to produce. The fuel tanks, for example, must be sturdy enough to support high-pressure gas, making its production costly.
Limited fueling infrastructure: There are still few natural gas fueling stations across the nation, most of which are located in areas that service long-haul trucks.
Performance issues: NGVs typically have a lower driving range than their crude oil counterparts due to the low energy density of natural gas.
Limited driving range: Unlike large commercial trucks, smaller NGVs have small tanks, which limits driving range due to the need for refueling.

Infrastructure and Support for NGVs

The support and infrastructure for NGVs in the U.S. are increasing, and the aim is to promote their adoption and improve the nation’s energy and fuel conservation measures. Some of the strategies in place are increased availability of fueling Infrastructure and government incentives.

About 1,000 natural fueling stations are available to the public across the country. The majority of those offer CNG, with about 50 offering the alternative LNG. For business and fleet managers, the increased availability of reliable natural gas suppliers provides an opportunity to install small fueling equipment and source gas in bulk.

Several states have provided incentives, such as tax credits, rebates and vouchers for NGVs and infrastructure owners, to encourage the adoption of natural gas vehicles.

Adopting Natural Gas Vehicles for Your Business

If you’re wondering how to adopt NGVs for your business, consider these two factors:

Fleet optimization: Converting your fleet to utilize natural gas has unique advantages that positively affect your bottom line. Qualities like fuel efficiency and the low cost of retail gas will help improve fleet performance while cutting down on fuel costs.
Cost-benefit analysis: Purchasing NGVs or converting traditional vehicles to use natural gas is costly upfront. However, natural gas is often less expensive, and there are tax credits and incentives that contribute to a good return on investment (ROI).

There are many industrial uses of helium, from welding to inspecting ships to producing TVs and smartphones — but the most well-known use of helium is filling balloons. This inert, colorless and odorless element has an extremely low density, making it chemically lighter than air and the ideal balloon gas.

However, filling balloons with helium isn’t as simple as picking up a canister and filling the balloon. Learn more about helium in party and weather balloons and where you can source the right helium below.

Differences and Variations in Helium Purity

While helium is applicable across industries, not all helium is the same. This gas varies in purity, and it’s essential to choose the right helium grade for your specific use. This way, you won’t use a higher grade of helium than is necessary.

The grading system for helium is a scale, with each grade’s number represented in its purity percentage. For example, Grade 6 helium has a 99.9999% purity, with six total “9s” noted in the percentage, and Grade 4.6 has a 99.996% purity, with four “9s” and one “6.” These are some of the most common helium grades and applications:

Grade 6: This is the highest helium grade and is the closest to being 100% pure. It’s used in numerous high-level applications, including as a cooling agent for superconducting magnets in MRI machines and for semiconductor chip manufacturing.
Grade 5.5: With a 99.9995% purity, Grade 5.5 helium is also largely used in research-based applications. It’s an ultra-pure helium that’s ideal as a shielding gas in welding and a cooling gas in fiber optics. It can also be used for some of the same applications as Grade 6 helium, such as semiconductor processing.
Grade 5: While slightly less pure than Grades 6 and 5.5 at a 99.999% purity, Grade 5 helium is also used for specific lab research purposes, such as in weather balloons and blimps. It can also be used for gas chromatography and mass spectrometry.
Grade 4.8: Grade 4.8 has a purity of 99.998% and is commonly used in military applications, though it can also be used in certain industrial processes.
Grade 4.7: This 99.997%-purity helium is often a tracer gas for helium leak testing, such as in containers. It can also be used in pressurizing and purging and cryogenic applications. One of the most common uses of Grade 4.7 helium is in breathing gas mixtures for deep sea diving.
Grade 4: This is most well-known as balloon-grade helium, with a purity of 99.99%. It can also be used in applications like vehicle airbags, but Grade 4 helium is the top choice for filling decorative party balloons.

What Is Balloon-Grade Helium?

When choosing helium for balloons, you should select Grade 4 helium or any helium with a purity of 99.99% or lower. This is one of the most accessible helium grades on the market and provides the exact results you need. However, if you need a higher purity so you can use helium in party and weather balloons, Grade 5 gas will work fine for both uses.

Keep in mind that different types of balloon material will hold helium better than others. Since latex is porous, helium will slowly seep out of a latex balloon over time. A foil balloon can float longer because it’s nonporous and can be refilled thanks to its self-sealing valve. No matter which option you choose, always use the highest-quality balloons available for the best results.

Sourcing and Storing Helium for Balloons

Once you have your balloons ready, it’s time to purchase your helium. The good news is that 99.99% helium is a standard option available through numerous suppliers. While the helium global supply chain has a few considerable challenges, you should be able to source what you need from your chosen retailer — feel free to connect with a Meritus Gas team expert if you need help.

That said, it’s important to note that Grade 4 helium, despite its lower purity rating, isn’t always the most cost-effective choice. Since higher-purity helium varieties are liquids, they’re less expensive and more efficient to transport. Consider using Grade 5 helium if you find a notable pricing difference.

Both using and storing helium properly are essential. Although helium is nonflammable, nontoxic, odorless and tasteless, it’s still necessary to disperse it only in a well-ventilated area to limit the risk of asphyxiation. Additionally, store your helium cylinder upright in a dry, safe place and secure it to ensure it doesn’t fall over.

Simple Balloon Inflation Tips

Using helium to fill balloons is easy once you understand the basics. First, make sure you have all the necessary items and accessories. In addition to your helium and balloons, you’ll need a regulator and ties to secure the balloons once filled. Either a single- or double-stage regulator will work, though double-stage regulators are best at parties or events where balloons will need to be filled consistently.

Now, you have everything you need to start filling. Get started with the following steps:

Place the cylinder on a level surface in a well-ventilated space.
Remove the plug on the cylinder.
Screw in the regulator.
Turn the valve to let out the gas.
Put the opening of a balloon over the regulator’s nozzle, holding it securely.
Tilt the nozzle slightly forward to allow the helium to flow into the balloon.
Release the nozzle once the balloon is filled properly.
Remove the balloon from the nozzle.
Tie off the balloon.

When you’re finished filling the balloons, close the cylinder valve and tilt the nozzle down to relieve regulator pressure before storage. It’s also important to consider balloon disposal after your event ends. If any balloons are left over, pop them to let out the helium and dispose of them properly. Keep the balloons weighted during the party to ensure none of them float away.

When you’re searching for compressed gases for your business operations, you’ll likely come across grades of gases referred to as “specialty.” With so many types of gases already on the market, you may not know how specialty gases differ from natural compressed gases and why they might be best for your needs. Explore our guide to learn more about specialty gases, their applications in different industries and how you can choose the best specialty gas supplier for your business.

What Is a Specialty Gas?

A specialty gas is made up of unique chemical compounds and is used in industrial, medical and scientific applications. These gases can come pre-made off the shelf or feature custom, one-off mixtures to enhance efficiency and precision in a specific process. Unlike standardized gases, specialty gases must meet a set of analytical specifications for certain uses.

Generally, specialty gases are zero gases, carrier gases, instrumentation gases, bump test gases or calibration gases. These gases include compounds distinguished by their unique properties and tailored for specific applications in manufacturing, research and other industries. Examples of specialty gases include a mixture of hydrogen and nitrogen or a combination of methane in argon.

In particular, purity is a crucial factor for specialty gases. Thanks to their high purity, specialty gases can perform accurately and reliably in industries where precision is paramount, like pharmaceutical production and semiconductor fabrication. Additionally, the integrity of certain products relies on gas purity, such as in electronic components.

Specialty Gases vs. Standard Gases

Specialty gases are high-purity chemical compounds that are made for specific applications in medical, scientific and industrial fields. Their controlled composition and purity levels differentiate them from standard gases, as they offer more accuracy and reliability.

Although the elements that make up natural and specialty gases are similar, they have significant disparities in their purity and composition. Where standard gases have widespread use, specialty gas compositions suit specific roles in various industries.

Ultimately, standard gases lack specific attributes and purity levels, making them ideal for less refined applications such as heat-treating processes in manufacturing.

The Critical Role of Specialty Gases

Several industries can benefit from using specialty gases — they’re even necessary in certain applications. For example, medical research teams can use specialty carbon dioxide in medical imaging and diagnostics for accurate readings. At the same time, food processing centers could use special mixtures of oxygen to preserve foods. These products provide various industries with unparalleled precision to reduce inefficiencies and drive productivity by elevating processes.

Applications of Specialty Gases in Commercial Manufacturing

While specialty gases are applicable in many industries, they have especially far-reaching and diverse applications in commercial manufacturing.

These gases contribute to exact control and calibration to ensure end-product quality. Additionally, they help to facilitate precise calibration in production and semiconductor manufacturing and create a controlled atmosphere in welding — argon-helium mixtures enhance weld quality. For meticulous accuracy, cutting and marking laser systems use gases like carbon dioxide and nitrogen.

Other applications of industrial specialty gases highlight their critical role in advancing efficiency and technology in modern manufacturing.

Some gases are highly flammable or combustible. Others are harmful if inhaled or exposed to your skin or eyes. If one thing is certain, it’s that the correct storage of compressed gas cylinders decreases the risk of accidents, damage to property and environmental hazards. Additionally, proper storage methods help maintain the gases’ integrity and ensure their intended use.

While safety is a major concern, adequate gas cylinder storage also prevents contamination. Manufacturing, construction and maintenance industries often use industrial gases in various processes, which means the quality of the gas is critical for optimal performance. Our industrial gas storage guide will show you how to store gas, the ideal storage conditions and how to prolong its life span.

How Do Storage Environments Affect Gases?

When considering the safe storage of gas cylinders in workplaces, consider the ideal storage conditions, as the environment will have an effect on gases, especially when storing specific types.

Impacts of Different Storage Environment Factors

The wrong temperature, humidity and space considerations can alter the quality of stored gases and increase health and safety risks. Gas storage guidelines recommend specific locations for these reasons. Here is how storage factors affect the integrity and hazard of industrial gases:

Temperature: Gas expands at higher temperatures, increasing the pressure in the cylinder. External heat or fire can cause compressed gasses to explode or create another fire source, especially when pressure relief valves release a flammable gas.
Humidity: When water vapor has no way to escape, cylinders can be exposed to dampness, causing valve protection caps to rust or stick. Also, if moisture finds its way into cylinders with open valves, it will result in internal contamination.
Space: If gases are stored indoors or in confined spaces with limited or no ventilation, leaked gases can accumulate. Some gases are denser than air and can cause toxic exposures, asphyxiation and even explosion with ignition sources.

Ideal Conditions for Compressed Gas Cylinders

Gas cylinders need to be stored in well-ventilated, cool and dry areas, preferably far away from possible ignition sources and combustible materials. This will decrease your risk of accumulating gas in case of a leak. Make sure the area is specifically designed for safe gas storage with appropriate fire-rated walls and ventilation.

The storage area’s temperature should be below 100 degrees Fahrenheit — be sure to ask your supplier about the lowest temperatures you can safely store the cylinders.
Keep cylinders as dry as possible.
The storage area should have enough space so cylinders can be grouped together by hazard class and full cylinders can be stored separately from empty cylinders.

Safety Measures for Storing Industrial Gases in Manufacturing Facilities

Every industry uses different types of industrial gases for various purposes, but the types of risks remain the same. Follow these standard procedures to store gas cylinders safely in your facility.

Divide full and empty containers: Store empty cylinders the same way you would full and functional cylinders, but keep them separate to avoid confusion.
Categorize gas containers: Divide and store similar gases together, such as flammable, oxidizers and toxic gases.
Keep cylinders away from heat sources: Keep gas containers far away from ignition sources, naked flames, combustible materials and electrical circuits.

Essential Safety Tips and Equipment

If you are someone who works with or handles industrial gas in some form, it is essential to use proper safety equipment. Here are a few essentials to be aware of:

Handle one cylinder at a time: Keep cylinders vertical as much as possible and avoid lifting them by the protective cap or guard.
Wear the right personal protective equipment (PPE): Use PPE like goggles, gloves, protective clothing and safety boots when handling industrial gas cylinders.
Use equipment designed for moving: Move gas cylinders or containers with a hand truck or cart.
Use a crane: If you need to use a crane, place the cylinders on a special platform with proper nets to prevent them from falling.
Secure stored gases: Use chains or straps to secure stored gases to a fixed surface or use a cylinder stand to prevent them from falling or moving.

Necessary Precautions and Safety Checks

If you are ever in doubt, review the gas safety data sheet (SDS) or contact your gas supplier. These are the common necessary precautions to adapt around industrial gas storage. 

Only accept labeled cylinders: Suppliers should provide gas in cylinders and containers with proper identifiable and precautionary labels.
Connect equipment before opening valves: Use the correct valve outlet connection and open the valve slowly facing away from you.
Let trained personnel perform transfilling: Transfilling cylinders can introduce contaminants into the container or cause overpressurization, creating potential safety hazards.
Call the experts: If you find any gas container issues, damages or leaks, immediately notify your gas supplier, as these pose safety hazards. Do not attempt to move these containers until given the go-ahead.

Industrial Gas Storage Compliance Considerations

The role of regulatory compliance is to prioritize the health and safety of employees, employers and their surroundings. Following strict guidelines regarding using, moving and storing gas containers helps mitigate the risks associated with industrial gases.

The Occupational Safety and Health Administration, the Compressed Gas Association, the National Fire Protection Association and the International Code Council are a few regulatory organizations to take note of in the industrial gas industry, with each of them having their own set of regulations.

Compliance with regulations enables organizations to do the following:

Preserve the environment: Some industrial gases are toxic and can cause harm to both people and the environment.
Keep the public safe: Mitigating risks can keep workers and the general public safe from any hazards and accidents.
Uphold an organization’s brand value: Upholding compliance shows an organization’s commitment to well-being, responsible operations and ethical business practices.
Gain a competitive advantage: People appreciate organizations that adhere to regulatory compliances and work with service providers that commit to the safety of their employees and the environment.

For example, since the hazards associated with industrial gases include fires and explosions, toxic gas exposures, oxygen displacement, and high-pressure systems, OSHA has put these gas storage requirements together:

When storing compressed gas cylinders inside buildings, keep them in a well-protected, well-ventilated and dry location that is at least 20 feet away from combustible materials.
Assign storage places away from elevators, stairs and gangways.
Do not keep gas cylinders in unventilated enclosures like lockers or cupboards.
Place and secure valve protection caps on cylinders.
Secure cylinders and use proper equipment when hoisting or transporting them.
Keep cylinders from dropping or being struck.
Cylinders should be secured in a vertical position when transported by powered vehicles.
Do not lift cylinders by their valve protection caps or use bars to pry them loose.
Use suitable cylinder trucks, chains or steadying devices to prevent cylinders from being knocked over during use.
Close the cylinder valve after use or when empty.
Separate oxygen cylinders from fuel-gas cylinders or combustible materials by at least 20 feet or with a noncombustible barrier.

How to Train Employees for the Safe Storage of Industrial Gases

Following regulations and using the correct equipment form only a small part of safe industrial gas storage. Many factors can contribute to gas-related accidents occurring at a workplace — one of them is poor staff training. Gas containers are often big and bulky, and it is easy for them to slip or to accidentally knock them over. That is why many accidents happen when workers try to move gas cylinders.

It is dangerous for gas cylinders to fall over, as cylinders could get punctured or valves may break off at the neck. This could cause compressed gas to rapidly release, resulting in the cylinder launching into the air or spinning out of control. Potential hazards from this occurrence may include:

Airborne cylinders can cause serious injury to people and damage property.
If the released gas is toxic, people could get injured from exposure.
In the case of flammable gas, any ignition or even static electricity can start a fire.

That is why it is essential for employees who will be working with or handling gas cylinders to receive training and know what to do during emergencies. Effective training programs should cover topics related to:

Hazard awareness: Workers should be familiar with the gas suppliers’ SDSs and the chemical properties of the gases the workplace stores.
Safety regulations: All employees need to know the storing requirements under the law and the safe handling procedures.
Safe handling methods: Both full-time employees and contractors should follow the proper handling procedures and know how to use equipment that moves gas containers correctly.
Site safety rules: People who visit or work on the site need to know the safety rules, including movement restrictions and prohibited activities.
Emergency response: Workers should be trained on evacuation and first aid measures and be able to locate first aid equipment and safety showers during emergencies.
PPE: Employees should know which PPE to use, how to use them and how to take care of or dispose of them properly after use.

Maximizing the Life Span of Industrial Gases Through Proper Storage

Another benefit of following regulations is that proper storage conditions can prolong the quality and usefulness of industrial gases. Facilities can implement strategies to extend the life span of the gases they use on-site, taking into account factors like environmental conditions, space constraints and costs associated with storing and disposing of old cylinders.

However, keep in mind that cylinders often degrade after two to three years when stored outdoors. Storing gas cylinders over the long term can increase the risks linked to moving gas containers. In comparison, cylinders containing corrosive gases degrade more quickly and can create regulator and valve problems. These cylinders should not be stored for longer than six months.

Here are tips for maintaining optimal storage conditions to maximize the life span of the industrial gases stored in your facility:

Detect leaks promptly: Inspecting and maintaining gas delivery systems and equipment regularly can help prevent leaks. You can reduce gas wastage by conducting regular visual checks and installing leak detection systems so your supplier can repair the cylinders sooner rather than later.
Maintain storage area: Ensure gas containers are stored in a cool and dry space with proper ventilation, where they will be protected from physical damage and exposure to moisture and contaminants.
Manage gas cylinder inventory: Implement a tracking and inventory management system to keep track of gas cylinders, monitor their usage and place new orders in a timely manner. This approach helps avoid unnecessary downtime and prevents losing cylinders due to expiration.
Train and educate employees: Teaching employees the importance of gas conservation can help create a culture of responsibility and awareness, contributing to the extension of industrial gas life spans.
Collaborate with gas suppliers: Gas suppliers can provide insights, recommendations and technological support to optimize gas usage and extend their life span with customized solutions.

Addressing Common Challenges in Storing and Handling Industrial Gases

Storing and handling industrial gases can present various concerns. Here are some common challenges and proactive measures to mitigate them:

Safety hazards: Industrial gases are often flammable, reactive or toxic and some have asphyxiating properties. These hazards can be minimized with proper staff training, appropriate safety equipment such as PPE for moving and handling gas containers, and regular risk assessments to identify potential hazards and implement mitigation measures.
Storage requirements: Different industrial gases have specific storage requirements to maintain stability and integrity. Ensure storage facilities and equipment align with guidelines from the relevant organizations. Maintain optimal storage conditions and mark containers according to regulatory requirements.
Gas leaks: Gas leaks lead to safety hazards, wastage and product loss. Conduct routine inspections of gas cylinders, valves and connectors to identify and repair leaks or damages. Encourage a culture of safety and responsibility by educating employees to be vigilant and report any irregularities.
Inventory management: Poor inventory management can lead to inadequate stock or expired gas cylinders. One proactive measure is to implement a first-in, first-out approach to reduce expired products. Track and monitor inventory and remove expired gas from storage.
