An OSHA COMPRESSED AIR SAFETY SHUT-OFF VALVES should be placed immediately after the air control shut off valve and before the hose on a compressor, and after each discharge port that a hose is connected to.

Before starting the compressor the air control valve should be closed completely. When the compressor unloads, open the air shut off control valve very slowly. Full port ball valves tend to work better than gate or butterfly type valves.

The air shut off control valve must be fully open for the OSHA COMPRESSED AIR SAFETY SHUT-OFF VALVES to work. Some portable air compressor manufacturers recommend start-up with the air control valve slightly open. In this case you may have to close the valve and reopen it slowly to the full open position, or wait for the safety shut-off valve to reset itself.

If the OSHA COMPRESSED AIR SAFETY SHUT-OFF VALVES fails to operate despite meeting all condi-tions, check the hose line for obstructions or a hose mender restricting normal air flow.

• Turn on air supply slowly (to avoid tripping OSHA safety valve). Prior to fully reaching operation conditions, the OSHA COMPRESSED AIR SAFETY SHUT-OFF VALVES should suddenly activate and stop air flow.

• If the OSHA COMPRESSED AIR SAFETY SHUT-OFF VALVE is not activated the unit should be disconnected and the lower flow range OSHA COMPRESSED AIR SAFETY SHUT-OFF VALVES should be used. This means you need to use a different valve with a lower scfm range.

• At temperatures below 40°F ensure that OSHA COMPRESSED AIR SAFETY SHUT-OFF VALVES are not subject to icy conditions which may prevent proper functioning.

ACS stocks air compressor check valves and safety valves as two important parts of your air compressor. Our safety valves are designed to relieve pressure if the air compressor exceeds the maximum safe pressure level. Our air compressor check valves aredesigned to keep air from flowing back into the pump when the air compressor is not in use. This way, your air compressor won"t risk being damaged by excessive pressure.

The National Board of Boiler & Pressure Vessel Inspectors is an organization comprised of chief inspectors from various states and territories of the US and Province and territories of Canada. The primary mission is to promote public safety.

We sat down to ask a few clarifying questions with our very own Marianne Brodeur, who was the owner of International Valve and Instrument (IVI), before its purchase by Collins in October of 2019. She also sits on the National Board as Chairperson of the subcommittee on Pressure Relief Devices. IVI has held a VR stamp for the last 34 years.

IVI is a VR certified safety valve repair facility, approved by the National Board of Boiler and Pressure Vessel Inspectors as a VR certificate holder (stamp 179). We certify pressure relief valves in the shop and in the field for sections V and UV. We also perform on-site testing (while the plant operates) providing documented reports for all valves tested. We are also certified to administer special process conversions regarding machining, welding, heat treating, and N.D.T. (non-destructive testing) with our VR certificate.

With our VR stamp, we repair all types of pressure relief valves such as Consolidated, Crosby, Kunkle, Farris, Spence, Anderson Greenwood, and numerous other O.E.M. safety and pressure relief valves.

Brand new, certified 1/8" Male NPT Threaded 70 PSI air compressor / tank pressure safety relief valve. Also known as a "Pop Off" or "Blow Off" valve. This relief valve is manufactured in the United States and is stamped with "UV" & "NB" symbols. The relief pressure of this valve is set at 70 PSI and is accurate within + or - 3% of the set pressure.

Maintaining the integrity of the pressure relief valve on an air receiver is absolutely essential when it comes to the on-going safe operation of a compressed air system. In this blog post we discuss what your responsibilities are as an owner of a pressure vessel (or air receiver) when it comes to maintaining its safe operation, and in particular what function the pressure relief valve serves and how to maintain its integrity.

An air receiver - or pressure vessel - is an important part of a compressed air system used to store compressed air as well as providing capacity during periods of peak demand. If improperly designed, installed, used or maintained, they can also be extremely dangerous and can lead to catastrophic outcomes such as fatalities, serious injuries and damage to property.

The ongoing condition monitoring of the vessel to ensure its safe operation, lies with the owner or operator of the pressure vessel. In accordance with the Standard AS/NZS 3788, depending on the size, design pressure and hazard level, an air compressor pressure vessel should be inspected externally every 2 years and internally every 4 years by a competent person.

One key component of an air receiver that needs to be inspected and certified on a regular basis is the pressure relief valve. Small but mighty, the pressure relief valve on an air receiver is a safety feature that effectively stops an air receiver from exploding if the pressure inside the vessel was to exceed its maximum allowable working pressure.

It achieves this thanks to its spring-loaded release mechanism. When the pressure inside the air receiver gets too high, the pressure pushes the pressure relief valve open allowing air to escape. Once the air receiver falls back below its maximum allowable working pressure, the pressure on the spring eases and the pressure relief valve will close. You can understand then, why maintaining the integrity of the pressure relief valve is absolutely essential for the on-going safe operation of the compressed air system.

Depending on the environment within which the compressed air system operates (for example if the compressed air system is located inside or outside), it is generally recommended that a pressure relief valve should be inspected every 12 months. Here an accredited inspector uses specialised equipment to test the functionality and effectiveness of the pressure relief valve.

In between that time - again depending on the compressed air systems operational environment - it is also generally recommended that the pressure relief valve should be manually checked for correct operation by a Competent Person. By manually lifting the valve (if possible) when the system is not pressurised, a Competent Person can check to make sure the spring is still intact and that there is not a build up of grime that could cause the valve opening to stick. Don’t forget though, that this is general advice only and you should always consult the OEMs operating instructions.

The pressure relief valve is just one area of an air receiver that needs regular attention to ensure the on-going safety of a compressed air system, but as you can see it is also a very important one.

Safety should be the priority in any workplace environment, whether it’s a construction site, a factory or another setting. Business leaders want to make sure their employees are safe, maintain high morale among their workforce and reduce the possibility of damaged or broken machinery. By employing practical safety measures, your company can benefit from increased uptime and fewer repair or replacement expenses.

Having safety measures in place is especially important when working with air compressors and other high-powered machinery. Compressed air should be treated with the same amount of care as other energy sources, as misuse or a lack of the proper precautions can present risks. It’s essential that all operators have the proper training, have read all instruction manuals thoroughly and understand how to mitigate safety risks and potential damage. Manuals contain an abundance of valuable information and will tell you how to keep your compressors running for longer periods without damage or injury.

There are also plenty of other resources that discuss how to maintain safety when operating pneumatic tools and air compressors. This guide will take you through the basics of using an air compressor, what to check before use, what to monitor and how to keep operators and workspaces safe to minimize air compressor dangers.

Air compressors are useful for many jobs, but they can also become dangerous when not maintained properly or misused. Compressor machines, hoses, pneumatic tools and electric connections can all pose hazards in the workplace. Air compressor accidents could potentially cause harm to workers and machinery.

What are some of the most common hazards related to air compressors? They include electrical dangers, fumes, flying particles, high pressures and high noise levels.

Flying particles and debris: Highly pressurized air and pneumatic tools can cause flying debris. If it strikes an operator, the pieces can cause bodily injury, or they can become lodged in the machine, causing damage.

High pressures:If high-pressure air is injected into the body, dangerous conditions and injuries, such as air embolism, ruptured eardrums and ruptured organs, can result.

Operators and workers can mitigate these dangers by following proper safety measures and air compressor precautions, which we will discuss later in the guide.

Depending on where you’re working, the intake air can contain pollutants and contaminants that are harmful to your health. From carbon monoxide to dust and debris, the air in the compressor collects from the surrounding space. To keep yourself safe while using the compressor unit, you must work in an area with proper airflow or natural air access, as well as protective gear, such as a respirator or dust mask.

While the likelihood of a workplace fatality due to an air compressor failure is low, it can happen in some extreme circumstances. If a compressor tank explodes, it can endanger your workers’ lives, but typically, the highest amount of danger lies with the operator. Due to the high pressures and pneumatic tools attached, operators must abide by all safety rules and regulations, including having the proper protective gear.

Every operator needs to undergo proper training and learn the relevant safety standards before using an air compressor. If you upgrade your air compressors or make any repairs, it’s essential to update operators on any changes so they know how to use the machine correctly and know what to look out for. It’s also important to check air compressor safety regulations from the Occupational Safety and Health Administration (OSHA) and ensure you’re in compliance with any that apply to your uses or machines.

The way your equipment and workspace are set up can have a significant impact on safety. Some air compressor and workspace setup tips to keep in mind include:

Component pressure ratings: Make sure that all components, including hoses, pipes and fittings, are rated for the maximum pressure of the air compressor.

Relief valves: Relief valves automatically release air if the pressure in the tank gets too high. These valves are important air compressor tank safety features, so you should never attempt to adjust, bypass or remove them.

Drain valves: If your compressor has an electric drain valve, make sure it is at least a foot and a half above the ground. Electric drain valves must be kept away from moisture.

Workspace air circulation: Intake air contains pollutants and carbon monoxide that can be hazardous to your health. For these reasons and others, it’s essential to keep your workspace circulated with clean air at all times.

Workspace humidity: It’s important to keep the humidity in your workspace from getting too high. To decrease the moisture in the air, try increasing air circulation in the workspace, operating your compressor for longer periods, using a peripheral crankcase heater or adding a dryer to your compressed air system.

Before using a compressor, you need to check various components to make sure the machine will work properly. To keep track of any issues and ensure you’ve looked at all the necessary areas, create an air compressor safety checklist for your operators to complete before each job. Some of the elements you may want to look at include:

Oil level: It’s essential to check and see if the machine has an appropriate amount of oil. Using it without an adequate amount of oil can ruin it to the point of requiring costly repairs or replacement. If it needs more oil, add oil to the reservoir but be careful not to overfill it. Also, be sure to keep oil from spilling onto the exterior of the compressor.

Fuel level:To run an air compressor, you need to have a sufficient amount of fuel. It can be a pain to have to refill in the middle of a job, as it requires you to stop, allow the compressor time to cool off and then refill the tank. Don’t refuel your air compressor when it’s on or has been shut off for only a short time. You should only conduct refuels and oil changes when the machine is cold.

Air filter:Whether you use a given compressor every day or only every once in a while, check the air filter before use. If it appears dirty or clogged, you should remove and wash it — if you have the right kind of screen — or replace it with a new filter.

Air connection:Before turning on your air compressor, make sure that it is securely connected to the air source. If the connection is weak or loose, the compressor may not perform as expected, and parts could disconnect, potentially leading to injury.

Outlets: Ensure your air compressor is only used with outlets that have the proper grounding. If you plug an air compressor into an incorrectly grounded outlet, it could damage the machine’s electrical circuitry and even cause a fire.

There are also air compression safety tips and procedures for particular parts of the compressor. Three of these components include the pressure regulation devices, air receivers and distribution lines. Each of these is significant in maintaining a healthy machine and operating it safely.

Valves:Ensure that the safety valves on your air tank are set to at least 10% or 15 psi — whichever is greater — above the operating pressure of the compressor but never higher than the air receiver’s working pressure limit. If using an air compressor in freezing temperatures, check that the safety valves are positioned in a way that prevents water from collecting inside the unit. If a valve freezes, thaw it and empty the compressor tank before reactivating the unit. The machine should also have shielded blowoff valves so sudden blowoffs don’t result in equipment damage or injury.

Air intake: The air intake should receive air only from clean, outdoor sources. Place a filter or screen at the intake valve to keep the intake air clean.

Speed: Check the manual that came with your compressor for the maximum recommended speed and ensure that you never run your compressor at speeds exceeding this level.

Draining:If your air compressor doesn’t have an automatic drain, be sure to drain the air receiver regularly so liquid does not build up inside of it.

Gauges and valves: Ensure that your air receiver has a pressure gauge and a safety valve that meets the American Society of Mechanical Engineers (ASME) standards.

Air hoses:Don’t let air hoses become bent or kinked. Check distribution lines regularly for flaws, damage and imperfections and replace any defective air lines immediately.

Operators should also take certain precautions while operating air compressors and after completing a project using an air compressor. It’s essential to remain in control of compressor units at all times. Sound footing and standing on a level surface at a safe distance from the unit is crucial as is keeping your hands, clothing and hair away from the air nozzle and tools.

While you can use compressed air for cleaning certain objects at low pressures and with a nozzle, you should never use compressed air for cleaning clothing or human skin. Don’t use compressed air to pressurize a vessel, such as to empty oil from a gearbox, as these vessels aren’t designed to handle high pressures. Don’t dry bearings using compressed air, as doing so can cause excessive rotations speeds that can cause bearings to explode.

Also, be sure to wear the proper safety gear for the job. No matter what tool you’re using for a given project, it’s vital to wear protective gear for your ears and eyes at all times. According to the Center for Disease Control, an estimated 22 million workers face exposure to potentially harmful noise every year. The risks involved with failing to wear hearing guards might not always be apparent at first, but adverse effects due to exposure to noise are often experienced later, in some cases years down the line. Personal protective equipment (PPE) to consider includes goggles, face masks, rubber or leather gloves, steel-toed shoes and leather or PVC aprons. Cotton clothing is not an effective barrier to compressed air. Cover any part of the body that is at risk of coming into contact with compressed air or flying particles.

To prevent safety issues, it’s crucial to keep an eye out for any potential issues while you’re using an air compressor. Once you start the machine and begin your work, be sure to check the following items consistently:

Surroundings: In addition to managing your own safety, keep an eye out for other workers and ensure you’re keeping the surrounding area safe. Make sure that all your hoses, cables and wires are tucked away where no one can trip on them and that you keep your area clean.

Voltage:Pay close attention to your air compressor’s voltage. If repairs are needed, power down the machine, lock and tag out all power sources and release all pressure from the compressor. If your compressor is designed for indoor use, don’t use it outdoors, as rain or wet conditions can cause electrical problems.

Air source:Be sure to check the air source itself regularly to ensure optimal performance and efficiency. The air source should be clean and dry. You can use screens or filters to clean the incoming air.

Air inlet:At the inlet, the air that goes in should be clean and free of moisture and should not exceed the maximum recommended pressure. If the maximum pressure rating of a particular tool is surpassed, it could cause various dangers, such as cracks, undue velocity or faulty pressure or output torque.

Performing preventative maintenance is essential to keeping your compressor running smoothly and safely. It can increase the longevity of your machine and improve its capabilities. Running a clean, well-kept machine will also promote the wellbeing of your workers and operators and help manage air compressor risks.

Receive the proper training:Anyone performing maintenance on an air compressor should have received the appropriate training to ensure they conduct maintenance tasks correctly and safely.

Follow the manufacturer’s recommendations: To ensure safety in maintenance and operation, it’s important to follow the care and maintenace recommendations of your compressor’s manufacturer.

Disconnect power: Before performing maintenance work, shut off the machine and disconnect it from all power sources. Lock open the electrical switch for the compressor and tag it so no one starts it by mistake.

Clean the unit properly:Cleaning your air compressor regularly will improve its performance and extend its life. When it comes to cleaning carbon remnants from the various parts of an air compressor, it’s safe to use soapy water or a lye solution, but you should never use anything flammable, such as kerosene. Following every cleaning, completely purge the air system.

Lubricate properly:Don’t use oils with low flash points to lubricate compressor parts. These oils could combust due to the high temperatures produced by air compressors during operation. It’s essential, however, to keep parts lubricated with the proper oils and to avoid over-lubrication to prevent corrosion.

Take steps to prevent rust: One of the most dangerous possibilities when it comes to air compressors is a rusty tank. Rust increases the unit’s chances of combusting, putting anyone nearby in danger. To prevent rust due to the accumulation of liquid, use the underside valve to drain the tank daily. If a tank becomes rusted, don’t attempt to repair it. A rusted tank requires replacement.

Handle tools safely:Before you install, remove, fine-tune or perform any kind of maintenance on your pneumatic impact tools or accessory parts, shut off the source of air, bleed the air pressure and disengage the air hose.

Report faulty equipment immediately:If you notice that repair work is needed that goes beyond regular maintenance, tag out the machine so no one uses it. Then, report the issue as quickly as possible so the machine can be repaired.

Although proper maintenance can help extend the life of your air compressor, you may still occasionally need to troubleshoot issues. Follow these compressed air safety tips when troubleshooting your equipment:

Shut down your compressor:Turn off your compressor, disconnect it from power and bleed any remaining air pressure before doing any troubleshooting or repair work. Make sure that the shutoff valve is always within reach in case something goes wrong during operation.

Follow safety procedures for hose malfunctions:If a hose malfunctions or comes apart at the coupling, you can prevent whipping with two components. One is an air fuse of the proper size, which you should install in the hose upstream. The other is a whip-inhibiting device that is placed along the coupling of a hose. If an air hose does start whipping around uncontrollably or another similar air hose problem occurs, don’t try to stop and control it by grabbing the hose. To prevent injury, turn off the air source before touching the hose.

Use reliable parts: If a component becomes damaged or needs to be replaced for any reason, use only reliable, high-quality parts that are the correct size, material and type for your machine. Using the wrong parts or low-quality components can result in decreased compressor performance, damage to your equipment and safety hazards.

Sullair’s spring-loaded safety valve is used as the compressor’s high-pressure shutdown protection function to ensure that the compressor stops before the safety valve is opened. This prevents the safety valve from opening and loss of lubricating oil when the compressor is running. out). The opening pressure of the spring-loaded safety valve has been set before leaving the factory, please do not change it without authorization.

The Sullair oil and gas separator tank is equipped with a Sullair spring-loaded safety valve. When the pressure in the tank exceeds the rated pressure of the safety valve, the safety valve will open automatically. The rated pressure of the safety valve has been set at the factory. For more safety, the monitoring system is generally set to shut down in the following situations:

If the spring-loaded safety valve is dirty and blocked, the safety valve cannot be opened or cannot be closed automatically after opening. If the safety valve cannot be opened, it will lose its function of protecting the pressure system, and the safety of the unit will not be guaranteed. If the spring-loaded safety valve cannot be closed automatically, a large amount of lubricating oil in the oil-air separator will spray out accidentally, causing property damage. Stop the machine every week to check the status of the safety valve.
