Safety Practices Using Compressed Gases

Caution High concentration in the atmosphere can cause immediate asphyxiation 

Because most modem labs have adequate ventilation, asphyxiation is seldom a problem. However, when work is being done in a basement, in rooms that do not have an adequate ventilation system, or when a gas is heavier than air, every precaution should be taken such as the use of the buddy system, having portable air supplies available, and intercom systems with regular check-in times. 

Always Secure Compressed Gas Tanks. A compressed gas tank should never be allowed to stand free. Instead, it should be supported by an approved tank support and the screws should be tightened by a wrench, not just by hand. If lying horizontal, the compressed gas tank should be prevented from rolling. 

Just about everyone has heard stories of compressed gas tanks being knocked over, thus snapping off the main valve, turning the compressed gas tank into a rocket. The Compressed Gas Association claims that this orifice is too small for the tank to become a projectile. However, if the tank contains a flammable gas, the question of whether the tank will turn into a rocket is of secondary importance. 

Keep Electric Lines Free from Compressed Gas Tanks. Compressed gas tanks are made of metal. Keeping electric lines away from compressed gas tanks helps to prevent spark development and potential shock to the user.

Dangerous when mishandled is the key phrase. Fortunately, years of experience with compressed gas has resulted in safe work practices and equipment that, if properly used, results in complete safety.
