There is one 4 storied building using as garments factory. The building is protected with Fire Hydrant System.
My question is:
1. The pump room is outside of the main factory building and the pump room is 2 hour fire rated structure. Inside the pump room, Diesel engine and tank (210 gallon capacity) is installed. Should we use automatic sprinkler system in the pump room? If yes, what will be the K factor to the sprinkler?
