Various types of fire pumps are used in fire protection systems. Types of fire pumps include: horizontal split case, vertical split case, vertical in-line, vertical turbine, and end suction. These fire pumps may be powered by an electric motor or diesel engine and on rare occasion powered by a steam turbine.

Class I liquids are the most hazardous from a fire safety standpoint, while Class IIIB liquids are the least hazardous. Class IA liquids are liquids that have flash points below 73 °F (22.8 °C) and boiling points below 100 °F (37.8 °C). Additionally, unstable flammable liquids are treated as Class IA liquids.
