The main standard that governs fire pump fixed-place installations in North America is the National Fire Protection Association's NFPA 20 Standard for the Installation of Stationary Fire Pumps for Fire Protection. [1] Fire pumps are powered most commonly by an electric motor or a diesel engine, or, occasionally a steam turbine.
A diagram of the MB-5's foam turret. The roof-mounted turret was designed by Cardox Ltd and fed by a 14 pounds per square inch (97 kPa) rotary vein pump (also built by Cardox Ltd). [3] It was manned by one firefighter, who would stand in a roof hatch. This hatch was positioned to the rear of the cab and would latch shut.
These were pump vehicles extensively used by the auxiliary fire service during the cold war and called upon to relieve the firemen's strikes in the 1970s and 1980s.
