GAS, BOTTLED (CYLINDERS)
All cylinders of gas should be correctly identified in accordance with International Regulations and used only for the purpose for which they are designed. Any poorly identified cylinder should be returned to the supplier for credit.
General Precautions
Before using a gas check the label to see that it is the correct gas
for your requirements. Never use a gas for any purpose other than
that for which it is purchased. Never maltreat valves, gauges or
cylinders. If leaks in the system are suspected check by applying
detergent and water only to the area suspected of leaking. Stiff
valves should never be forced. Any difficult cylinder should be
returned to the supplier with an explanatory note. All cylinders and
gauges for flammable gases have lefthand threads while
nonflammable have right hand. Never completely empty a gas
cylinder. Do not open valves too rapidly it could cause
overheating of the regulator leading to an explosion. Cylinders must
be stored and constrained in a suitable rack or stand to prevent
falling. Always store in a cool well ventilated location. Couple
cylinders to equipment only through a regulator. Always plan for any
emergency keep appropriate emergency equipment on hand.
