NFPA 20, 4.12.6 "Ventilation. Provision shall be made for ventilation of a pump room or pump house."
DIESEL FIRE PUMPS - These rooms require a lot more air for combustion air and heat removal. This is usually done in generator and boiler rooms with separate fan-forced intake air and exhaust ducts to the outside. In the case of a fire pump, fireproofing these ducts through the building offer additional "protection" under NFPA 20, 4.12.1 in the event of a fire. Diesel data sheets show the amount of CFM required for the various engines. In addition, the extra distance for the exhaust pipe lengths to the outside needs to be considered. Some of the engine manufacturers have calculators on their websites for VENTILATION, COOLING LOOP and EXHAUST PIPING.
PUMP ROOM TEMPERATURE LIMITS - Most microprocessor controllers are limited to 120 deg. F. A small non-vented pump room, especially on a west wall, could easily exceed that with a motor running under load on a hot 100+ degree day.
My question? This site/facility does not have an emergency backup generator. Do we need a backup generator to power the exhaust fan and/or the unit heater?
In the event of power loss during winter… a room temp sensor would send supervisory alarm company for an owner response.
Also, please confirm the Jockey pump does not require backup power.
