Boiler Safety - OSHA Safety Manuals

Mar 15, 2017 · Boiler Safety. Workers that use, maintain, and service boilers know that they can be potentially dangerous. Boilers are gas-fired or electric closed vessels that heat water or other liquid to generate steam. The steam is superheated under pressure and used for power, heating or other industrial purposes.

Recommendations For A Safe Boiler Room

The boiler room is for the boiler. The boiler room should not be considered an all-purpose storage area. The burner requires proper air circulation in order to prevent incomplete fuel combustion and production of carbon monoxide. Therefore, keep the boiler room clean and clear of all unnecessary items.
