Note:

The fire resistance rating stipulated in this table shall be the minimum.

N = no specific requirement on compartmentation/door rating.

B = compartmentation and door rating of the special purpose room shall not be less than the fire resistance of the elements of structure of the building where the room is located.

S = Sprinkler system has to be extended into such rooms.

Ex = Sprinkler system is exempted from the corresponding area provided the area is fitted with an automatic fire alarm system installed according to SS CP 10.

(1) = Requirements stated herein apply to store room which is required to be compartmentalised.

(2) = Requirements stated herein apply to kitchens in hotel, restaurant, coffee house or other similar places where the preparation of food is required. However, special considerations will be given to the followings:
