My question is about the fire protection for a pump room for an aircraft hangar.
The pump room has a clear distance of 65 ft from the hangar, it is just protected by a shelter (Ceiling without walls) with fire extinguishers. It has 3 vertical pumps with diesel engine drivers.
Does the pump room must be protected by an automatic sprinkler system or they can protect with fire extinguishers?
Must be a room with fire resistance walls?
