Mandatory inspections to all penetrations through fire and smoke resisting elements were introduced on 2 June 2018 following evidence that works required to resist the spread of fire were not being carried out adequately.
Unsealed penetrations are unable to provide protection against the spread of smoke, heat and toxins. Despite their often insignificant appearance, the consequences of inadequate protection, can leave building occupiers vulnerable to potential injury in a fire scenario.
Fire-resisting walls, floors and ceilings are installed to slow or stop the spread of fire through a buildings fire or smoke compartment or between separate tenancies, therefore, unsealed penetrations could reduce the effectiveness/ fire resistance level.
What is required to be inspected?

- Any lightweight construction building component that is required to resist the spread of fire in at least one apartment in each storey.
- One of each stair, lift or service shaft of lightweight construction required to resist the spread of fire in each storey
