Standards & Guidance(S ) f fAD B3 (Sect 10) - Protection of openings and fire stopping

10 2 ‘If a fire-separating element is to be effective10.2 If a fire-separating element is to be effective, every joint or imperfection of fit, or opening to allow services to pass through the element, should be adequately protected by sealing or fire stopping soadequately protected by sealing or fire-stopping so that the fire resistance of the element is not impaired’

10.17 adds the requirement that:Joints between fire separating elements should be fire stopped; andp g pp ;All openings for pipes, ducts, conduits or cables to pass through any part of a fire separating element should be:• Kept as few in number as possible; and• Kept as small as practical; and• Fire stopped (which in the case of a pipe or duct should allow for• Fire stopped (which in the case of a pipe or duct, should allow for

thermal movement).

Pipe Wraps & Collarsp pHTM05/02 Clause 6.16 - To maintain the integrity of compartmentation, openings should be limited to:

b. openings for pipes of not more than 160mm diameter which, if exposed to a temperature of

p g

diameter which, if exposed to a temperature of 800°C, will not soften or fracture to the extent that flames or hot gases will pass through the wall of the pipe;wall of the pipe;

c. pipes of materials other than those in (b) above of not more than 40mm diameter;;

d. pipes of any diameter which are provided with a proprietary seal which has been shown by test (for the diameter of pipe proposed) to maintain the fire resistance of the compartment structure;

Fire Dampersp

HTM05 02 D1 t tHTM05-02 D1 states: -

All fire dampers should be installed so that they maintain their integrity against the passage of fire for the required period of fire resistanceagainst the passage of fire for the required period of fire resistance

A fire damper should be adequately fixed into, or to, the construction it is protecting.
