Boiler Safety | OSHA Safety Manuals

The steam is superheated under pressure and used for power heating or other industrial purposes. Though boilers are usually equipped with a pressure relief valve if the boiler fails to contain the expansion pressure the steam energy is released instantly. This combination of exploding metal and superheated steam can be extremely dangerous.
