Shared Services Partnership Facilities Services Common Problems & Fire Stopping Solutions
Standards & Guidance AD B3 (Sect 10) - Protection of openings and fire stopping 10.2 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 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; and 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 thermal movement).
Pipe Wraps & Collars HTM05/02 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 800 C, will not soften or fracture to the extent that flames or hot gases will pass through the 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;

PU Polyurethane Expanding Foam Normal PU Expanding Foam is not an intumescent product (i.e. It will not expand when heated).
Which of these is fire rated? A B C Methods for identification: - Coloured pigments Pot of paint, and/or Labels Regulation 38 Provision i of information.
PU Fire-Block Foam
PU Fire Rated Foam Many fire-rated PU foams are available & product identification difficult Claimed periods of fire resistance are achieved under strictly controlled test conditions, with a high standard of quality control for installation of sample tested Products used on site Often used on irregular shaped openings of varying widths beyond scope of application (hollow stud partitions) Do contractors understand the limitations of products in use? Little quality control (are voids completely l filled?) Reaction to Fire B1 & B2 Rating DIN 4102 Before specifying/using any product p y g g y p ensure it s fit for the intended application review test reports. Up to 5 hours protection
