HOW TO MAINTAIN insulating gas CIRCUIT BREAKER

insulating gas is odorless, colorless, tasteless, and nontoxic in its pure state. It can, however, exclude oxygen and cause suffocation. If the normal oxygen content of air is re-duced from 21 percent to less than 13 percent, suffocation can occur without warning.
