ABSTRACT:
Electrical apparatus cooled with a stream of hydrogen gas is protected from overheating by applying a coating to a portion of the apparatus which is exposed to the gas stream. The coating contains a compound which decomposes between 80.degree. and 200.degree. C. to produce a gas detectable by a monitor. The monitor detects gases heavier than hydrogen in the gas stream and sounds an alarm when they are present.
