Electrical machines

Small quantities of ozone are produced when oxygen and air are subjected to an electrical discharge and it is, therefore, found in the neighbourhood of working electrical machines. Probably a small quantity of atomic oxygen is initially produced most of this recombines quickly to give oxygen, Oj, but a few atoms react to form ozone ... [Pg.263]

This is a location which is continuously contaminated with explosive gases, chemical vapours or volatile liquids and thus is highly susceptible to fire hazards. Installation of electrical machines in such areas should be avoided as far as possible, to reduce cost, facilitate maintenance and take other precautions. [Pg.179]
