Older fire doors: check for asbestos before disturbing the opening

The replacement fire door has been specified, but what about the materials inside the old door and behind its frame? Before removing trim, drilling or dismantling, ask whether the asbestos information covers what the job will actually disturb.

HSE identifies fire doors as one place where asbestos can be hidden within a building. This does not establish that any particular door contains it; it is a reason to investigate rather than guess. HSE guidance on possible asbestos locations. (hse.gov.uk)

Existing guidance, not a new deadline

This article offers practical planning advice for existing non-domestic buildings in England, Wales, Scotland and Northern Ireland. It draws on HSE guidance and, for Northern Ireland, HSENI's survey guidance. It is not a sampling procedure, removal method or statement that identical legislation applies throughout the UK.

No new September requirement is being announced. HSE's *Asbestos: The survey guide*, HSG264, is existing guidance: the accessible document is its second edition, published in 2012. HSG264. (hse.gov.uk)

Look beyond the door leaf

HSG264 identifies asbestos insulating board—often shortened to AIB—packers around door frames, particularly fire doors. Packers are pieces used between the frame and surrounding construction. The potential issue therefore extends beyond the leaf being replaced. HSG264, Appendix 1. (hse.gov.uk)

Our recommendation is to describe the whole proposed disturbance when asking for asbestos advice: the leaf, frame, trims and any adjacent wall or finish affected by the work. Do not remove an architrave yourself simply to find out what is behind it. Arrange the necessary investigation through the people managing asbestos and the project.

Does the survey answer this job's question?

HSE distinguishes a management survey, supporting normal occupation and use, from a refurbishment or demolition survey, which investigates materials affected by intrusive work, including concealed materials. It also warns that restrictions can leave areas uninspected. HSE survey guidance. (hse.gov.uk)

The practical question is not simply, “Have we got an asbestos survey?” Ask whether its purpose, coverage and access match the planned door work.

HSENI's report guidance similarly emphasises stating which areas were inspected, which were excluded and why. Its point is that users should understand the inspection's boundaries rather than assume coverage. HSENI guidance on survey reports. (hseni.gov.uk)

For specifiers: brief the investigation before pricing removal

Consider a fictional school refurbishment. The contractor receives a management survey with no asbestos recorded in the corridor. However, the report excludes concealed areas behind door frames. The work package includes removing those frames.

Our suggested response is to ask the client and competent asbestos adviser to resolve that gap before the affected work starts. The corridor entry alone does not answer the question about an excluded concealed area.

When preparing the brief, identify:

• which openings are affected;
• what will be removed, drilled or otherwise disturbed;
• what existing information and exclusions need review;
• who will arrange further investigation and communicate the outcome.

Allow time to act on the findings, not merely to receive a report.

For installers: stop when information and conditions differ

Before starting, ask your employer to explain the asbestos information relevant to the opening and the agreed response to an unexpected material.

HSE advises workers who encounter material they suspect contains asbestos to stop work and speak to their employer or the building owner. It also cautions that a survey may not have found every location. HSE worker guidance. (hse.gov.uk)

Do not continue opening up to identify the material yourself. Escalate the uncertainty and obtain competent advice.

For the next older-building door job, ask one focused question: does the asbestos information cover everything this work will disturb? Resolve any missing coverage before turning a concealed-material question into an on-site discovery.
