Firefighting shaft components and outlet locations

NOTES: 1. Outlets from a fire main should be located in the firefighting lobby or, in the case of a shaft serving flats, in the firefighting stairway (see Diagram b). 2. Smoke control should be provided in accordance with BS 9999 or, where the firefighting shaft only serves flats, the provisions for smoke control given in paragraph 2.34A may be followed instead. 3. A firefighting lift is required if the building has a floor more than 18m above, or more than 10m below, fire service vehicle access level. 4. This diagram is only to illustrate the basic components and is not meant to represent the only acceptable layout. The firefighting shaft should be constructed generally in accordance with the relevant recommendations of BS 9999. 5. For the minimum fire resistance of lift doors see Table 4.5.
