Industry:Fire safety
A mechanical or gravity system intended to move smoke from the smoke zone to the exterior of the building, including smoke removal, purging, and venting systems, as well as the function of exhaust fans utilized to reduce the pressure in a smoke zone.
Industry:Fire safety
A mechanical pump (usually of the rotary type) that uses oil to seal the clearances between the stationary and rotating compression members. The pump is equipped with an inlet valve through which a suitable quantity of atmospheric air or “dry” gas (ballast gas) can be admitted into the compression chamber to prevent condensation of vapors in the pump oil by maintaining the partial pressure of the condensable vapors in the oil below the saturation value (sometimes called a vented-exhaust mechanical pump).
Industry:Fire safety
A mechanical switching device used for isolating a circuit or equipment from a source of power.
Industry:Fire safety
A mechanical switching device used for isolating a circuit or equipment from a source of power.
Industry:Fire safety
A mechanically driven power source that can be removed from the fire apparatus and operated at a location that is remote from the fire apparatus.
Industry:Fire safety
A mechanically integrated assembly of modules or panels with a support structure and foundation, tracker, and other components, as required, to form a direct-current power-producing unit.
Industry:Fire safety
A mechanically or electrically operated platform used to work at various heights within a building.
Industry:Fire safety
A mechanism whose automatic or manual operation leads to the discharge of extinguishing agent.
Industry:Fire safety
A medical condition that would preclude a person from performing as a member in a training or emergency operational environment by presenting a significant risk to the safety and health of the person or others.
