Gas Cylinders must be chained or strapped to a bracket, wall or bench using a separate strap/chain for each cylinder.
It is very important to always use a proper cylinder cart to move gas
cylinders ; do not roll or drag them into place. There is a cylinder cart in B-05 ESB which EAS personnel can use to more gas cylinders. Once you are finished, please return the cart.
Never move a cylinder without the cylinder’s valve cover firmly in place. Gas cylinders can become dangerous missiles if they are knocked over and their valve is snapped off.
Gas cylinders can be one of the most dangerous items in a lab in the event of a fire.
Always turn a gas cylinder off using the valve at the top of the cylinder – DO NOT use the regulator to turn off the gas flow. Corrosive gases can degrade the regulator’s rubber or plastic diaphragms over time and allow the contents of the cylinder to leak into the room.
Cylinders must be stored at least 10 feet from the exit to a room and cylinders must be chained or strapped security so they cannot fall or be knocked over. Cylinders should be strapped in place by individual holders, not one chain used to hold several cylinders together.
Cylinders with flammable gases should be grounded.
Cylinders, like all chemicals should be sorted by the types of gases they contain. DO NOT store flammables and oxidizers together. Do not store incompatible gases beside each other.
If there is a problem with a gas cylinder in the lab, immediately advise the Lab Supervisor of the situation. (A situation with a gas cylinder could be from: a faulty valve, a sudden gas release, a collision, a fire, an explosion in the room, the cylinder has rolled off of a vehicle, a chemical leak or spill in the lab that affects the cylinder.) Contact Praxair at 1-800-363-0042. Praxair will either send out trained personnel to deal with the situation or the Fire Department will be called in to vent the gas off, depending upon the type of emergency.
