Safety Can Be a Real Gas

Safety can be a Real GasOn just about any construction site, you’ll find compressed gas bottles. Electricians work near these bottles, if not directly with them. In a maintenance environment, multi-craft or not, these bottles are also present at times.

If you knock one over and it’s capped only with the regulator set, the bottle could take off like a rocket. Because of the energy stored within, even a partially charged bottle can easily puncture masonry walls. That’s one danger, and it applies no matter what gas is in the bottle. Among other measures, you protect against it by:

  • Always removing the regulator and capping the bottle between uses.
  • Using proper bottle carriers and restraints.
  • Placing the bottles on a firm surface away from traffic areas.
  • Never lift a bottle by the regulator or transport it with the regulator attached; remove and cap, instead.

There are breathing dangers with these gases, also. Nitrogen (for purging) isn’t flammable, but it can kill you. Another danger is combustion/explosion, depending upon the gas. Gases for welding (e.g., acetylene or oxygen) are highly flammable. Some cautions:

  • Never apply heat to the bottle. Sometimes gas will cease to flow, due to freezing. If that happens, replace the regulator or pour lukewarm water over it.
  • Beware of hidden pools of gas above and below. Some gases are heavier than air, some lighter. So you may take gas readings at eye level and detect nothing.
  • Wrap hoses loosely, not tightly.
