A common cause of explosion is the runaway firing condition that takes place when the boilers burner does not shut off. In this case, when the hot-water heater is connected to the city water supply on one side and the building hot-water service on the other, the check valve will shut off and no back pressure will go into the city side.

Practical guidelines for determining electrical area

Boiler houses are normally well ventilated, but the ventilation has usually been designed to provide air for combustion and to control room temperatures, rather than help disperse small leaks. The security of gas pipework operating at any pressure should at least be considered in any

Hazardous Area Classification - North America

17/07/2003 · 24 Jun 03 11:52 OSHA regulations seem clear that if a flammable gas is present in the piping, an area must be Class I, Div 2. However, our steam boiler area (natural gas feed) is not a classified area. When I asked our EE about this, he said that all steam boilers are sold with general purpose instruments.
