Using this drawing, and knowing that each space is 32 feet long (i.e. 9.75 meters), the width of each space can be estimated as being :

Fire Rooms (from forward to aft) :

FR-1 : 64 feet / 19.5 meters

FR-2 : 69 feet / 21.0 meters

FR-3 : 73 feet / 22.3 meters

FR-4 : 73 feet / 22.3 meters

Engine Rooms (from forward to aft) :

ER-1 : 67 feet / 20.4 meters

ER-2 : 71 feet / 21.6 meters

ER-3 : 73 feet / 22.3 meters

ER-4 : 73 feet / 22.3 meters


It was previously estimated that the the uptakes are about 8ft x 6ft (i.e. about 48ft²) and the intakes are about 6ft x 6ft (i.e. about 36ft²) :
