Before any fire stopping works being specified, assessing the fire breaks is an essential part of remediation. Using the fire strategy documentation as a guide (listing the required wall resistance, i.e. 30, 60, 120 minutes) a full inspection should be carried out individually identifying the types of penetrations, the types of services and the wall construction to specify the correctly matched fire stopping detail.
Fire stopping details should be installed with supporting evidence that the seal has been tested and effective at reinstating a fire separation in the exact situation it is used for. Different materials, and services behave differently when heated and ensuring the correct match is a key part of fire stopping installation.
Buildings evolve, a full fire stopped property could become a risk after minor adjustments by a plumber or a new cable run being added. An annual inspection program of a sample set of seals installed will ensure any wear and tear over time or new penetrations made into the fabric are quickly identified and rectified.
