Never rely on the color of the cylinder for identification. Compressed gas cylinders are used in a variety of applications involved with ambient air monitoring. C); or 3. These tools help to remove valves from gas cylinders before proper disposal or recycling. Large seat orifice provides faster vacuum and filling rates. 18. Instead of using a method that makes dropping or striking likely, OSHA gas cylinder transportation regulations require workers to move gas cylinders by rolling them along their edges. When workers move cylinders by hoisting them, they should be securely attached to a cradle, slingboard or pallet. Because of the high internal pressure in compressed gas cylinders, they can become projectiles if stored or transported in a manner that could damage the valve. Gas identification is typically stamped or stenciled onto the cylinder – or on a label affixed (or otherwise attached) to the cylinder. For use in cylinders containing oxygen, argon, carbon dioxide, nitrogen, helium and hydrogen, as well as welding gas mixtures. All compressed gases are hazardous because of the high pressures inside the cylinders. CNG cylinder inspection labels are applied to CNG cylinders to demonstrate the "Pass" or "Fail" result of a detailed CNG cylinder inspection. These inspections are required by the National Highway Transportation Safety Administration's (NHTSA) FMVSS 304 which states that a detailed visual inspection of all CNG cylinders must be conducted by qualified CNG fuel system inspectors every three years or 36,000 miles (whichever comes first) and after any fire or accident. Standard Interpretations. To help prevent serious injury to yourself and others, follow these safe storage practices. 3) General Safety Precautions Of Compressed gas cylinder: Name of the gas and chemical formula shall be mark on the cylinder. 800.448.0501. Open the valves from side. Its function is very critical as the compressed gases contained within them are subjected to explosion if any mishandling is caused. F. Mark compressed gas cylinders legibly, for the purpose of identifying the gas content, with either the chemical or the trade name of the gas… The cylinder valve should be positioned so that it is accessible at all times. – The cylinder valve is NOT used to regulate gas flow or pressure. Compressed gas cylinders should be stored – upright and secured with sturdy restraints – in dry, well-ventilated areas, with their contents (and hazard class) clearly marked. Valve protection for compressed gas cylinders. Always verify that you have the correct regulator for your application. Examples of CGA fittings would be CGA-580 for Non-flamable, Non-oxidizing gasses such as Nitrogen, Argon, or Helium.

Gas can be released deliberately by opening the cylinder valve, or accidentally from a broken or leaking valve or from a safety device. Leaking cylinders may displace air, causing an oxygen-deficient atmosphere that can lead to unconsciousness or death. Our valves are precision made with high-quality materials and components meeting tight Compressed Gas Association (CGA) specifications. Compressed Gas Cylinder Valves for Various Gases, Aluminum and Steel Cylinders. This valve allows the cylinder to contain gases and allows gas to be filled into or emptied from the cylinder. All compressed gases are hazardous because of the high pressures inside the cylinders. Gas can be released deliberately by opening the cylinder valve, or accidentally from a broken or leaking valve or from a safety device. Even at a relatively low pressure, gas can flow rapidly from an open or leaking cylinder. Valves are available from small to large cylinders up to 6000PSI service pressure.

A gas or mixture of gases having, in a container, an absolute pressure exceeding 104 psi at 130 deg. A sudden release of these gases can cause a cylinder to become a missile-like projectile capable of penetrating a concrete block wall. E. Limit inside storage areas for fuel gas to a total gas capacity of 2,000 cubic feet (about 13 large cylinders). – When opened completely, the valve seals off its own packing box. Helium Balloon Fillers and Inflators are one of Compressed Gave Valve’s featured products. Compressed Gas Cylinder Valve Protector. Our interpretation letters explain these requirements and how they apply to particular circumstances, but they cannot create additional employer obligations. •After the regulator is attached, the cylinder valve should be slowly opened just enough to indicate pressure on the regulator gauge (no more than one full turn), and all the connections checked with a soap solution for leaks. Compressed Gas Cylinder Safety Equipment Suppliers : JTC Valve Sales Gas cylinders may contain gases that are flammable, toxic, corrosive, asphyxiants, or oxidizers.

Standard cylinder-valve outlet connections have been devised by the Compressed Gas Association (CGA) to prevent mixing of incompatible gases. They come with a standard rubber tilt valve, and can include built-in ribbon cutter and contents gauge. C) regardless of the pressure at 70 deg. $33.36. Services include cryogenic repair, telemetry, cylinder re-qualification, and gas cylinder cradle assembly. According to OSHA Hazard Communication Standard: “Compressed gas” means: 1. All marking on the valve neck, protects against damage. Cylinder Valves • Have Compressed Gas Association (CGA) standard outlet ports. OSHA requirements are set by statute, standards and regulations. We manufacture world-class cylinder caps, valve protection, couplings, thread protectors, and compressed gas components. Add to Compare. As you might expect compressed air is the cheapest of the gases that are used in welding because it's air. (Though it is often purified a little). When you mix compressed air with another fuel then it can produce a strong flame at a lower temperate than an oxy-fueled flame. Safe handling of these cylinders is required for all concerned. 3/8-18 NGT CBI 5 200 3 Acetylene 200 .625-20 NGO RH Ext.

This type of device is most commonly found with medical-grade gas cylinders. 3/8-18 NGT Are all compressed gas cylinders subjected to periodic hydrostatic testing and interior inspection by suppliers? Once the cylinder pressure decreases to the valve’s pressure setting, the valve will normally reseat without leakage. Compressed Gas Cylinder Safe Handling, Use and Storage September 13, 2017 Safety Resources Page 4 of 29 ... Cylinder valve connections on regulators are also designed to minimize the chances of using the wrong regulator. Removing the valve ensures no material is left in the cylinder. C); or 2. Brands. Always point the valve and opening away from the body and away from anyone else in case there is a failure to the regulator, which may cause the valve stem on the regulator to fail and blow out. • Cylinder valve is an ON/OFF switch: open or close completely. • Compressed Gas Assocation(CGA) number on valve tells you a lot • CGA plus 3 digits –e.g., CGA 540 • Number identifies shape and thread of inlet and outlet connections –where you attach to valve • Indicates what gases might be inside • Will sometimes tell you exact gas • Will indicate characteristics: corrosive, flammable, inert, etc. Cylinder valves marked with “CGA” plus a 3 digit number correspond with a type of gas or gases that may be in the cylinder: In this example, above the date code is CGA580.
