4.3 ACCESS TO BUILDINGS WITH RISING MAINS
R Rationale - Clause 4.3The requirement for breeching inlets to be sited within 18m of the fire engine accessway/fire engine access road is for expediency of conducting firefighting operation. With this distance, only one length of hose would be needed for firefighters to provide water supply to the dry risers and/or fire water storage tanks.
Breeching inlets shall be visible from the fire engine accessway/access road to avoid delay in locating them upon arrival of the firefighting crew.
Buildings fitted with rising mains and automatic sprinkler system shall have fire engine accessway/ fire engine access road for firefighting appliances within 18m of breeching inlets. The breeching inlets shall be visible from the fire engine accessways or fire engine access road.
