Hydrostatic Pressure Testing of Fire Extinguishers

It is claimed by some authorities who should know, that many fire extinguishers hanging on their brackets throughout the country are deteriorating from either neglect or lack of proper supervision.

Soda and acid extinguishers manufactured in recent years of a new design are tested to 500 p.s.i. (pounds square inch). In previous years, manufacturers pressure tested to 350 p.s.i. Very few extinguishers, since manufactured, it is said, have ever been re-tested to the original pressure test.
