• In order to eliminate the possibility of gas escaping through leaks or
improperly closed valves, when gas welding or cutting, the torch
valves shall be closed and the gas supply to the torch positively shut
off at some point outside the confined space area whenever the torch
is not to be used for a substantial period of time, such as during lunch
hour or overnight. Where practical, the torch and hose shall also be
removed from the confined space.
