Association for Specialist Fire Protection

Thank you for contacting the ASFP. This page is for those who have scanned the QR code on the FIS ASFP tape attached to fire resisting partitions and other walls in buildings. It gives you advice on what to do when you need to or have already breached a fire resisting wall or floor for example when installing cables or pipes.

Fire Label

To prevent the spread of fire in buildings, they are sub-divided into fire resisting compartments. Openings are needed in the compartments for people to enter and leave and also for services such as cables, pipes and HVAC equipment. To ensure that the compartments work in the event of fire these openings need to be sealed or ‘fire-stopped’. In the case of openings for people this is done by using fire doors and you will be familiar with their location and operation in buildings. Cables, pipes and HVAC equipment are sealed with fire resisting ‘penetration seals’ and you need to be competent to install these.

You might think that holes hidden above suspended ceilings are not important, but deaths have occurred and significant damage by smoke spread has occurred in buildings with inadequate fire-stopping. There is also an increasing awareness of the problems of deficient fire stopping by building owners and main contractors; and steps are being taken to crack down on inadequate work.

You MUST make good any holes that you make in fire resisting walls or floors; the guidance below will assist you in this. If you have any further questions, do not hesitate to contact the ASFP by phone or using the web enquiry service.


The ASFP has published a number of videos and guidance documents on fire-stopping. The links below take you to the relevant video or publication. All publications are free to download.

Video - The correct specification and installation of fire-stopping

This describes why any breaches in compartment walls and floors for service openings must be appropriately fire stopped.  It highlights the inappropriate use of so called fire-rated polyurethane (PU) foams as an issue of significant concern. These are often sold on the basis of their fire retardancy rather than the much more severe fire resistance tests that fire-stopping must satisfy. Click to view

ASFP TGD 17 Code of practice for installation & inspection firestopping

This document is aimed at those responsible for designing and procuring fire-stopping and those responsible for on-going up-keep and maintenance. It gives information on how and who to use to install fire-stopping and also includes details of inspection regimes that should be carried out both after installation and throughout the life of the building.

ASFP ‘Red Book’ Fire-stopping: penetration seals, linear joint seals and cavity barriers

This is the authoritative fully illustrated ‘bible’ on fire-stopping and is referenced in Approved Document B of the Building Regulations.  It includes descriptions of all the types of firestopping currently used together with their strengths and weaknesses. It has detailed information on the fire testing, certification and CE marking of fire-stopping products. Finally, it contains data sheets for ASFP member products which have been comprehensively tested and certificated for fire-stopping. Click to download
