A sample answer to question 1

How do you carry out an inspection of an existing fire door, and what are the key things you check?

I begin by identifying the door: looking for a certification label or plug, the rating such as FD30 or FD60, and the location against the fire strategy. I then check the leaf for damage, delamination or unapproved holes, and check the frame and its fixing to the wall. Gaps are measured with a feeler gauge, typically around 3mm on the head and jambs, and at the threshold up to about 10mm unless the certification states otherwise. I check the intumescent strips and smoke seals are present, continuous and undamaged, and that hinges are CE or UKCA marked, correctly fixed with at least three, and fully screwed. I check the closer works properly, closing the door fully from any open position, and that the latch engages. Glazing must be fire-rated, with correct beads. I record findings with photographs on a numbered plan and grade the remedial priority, in line with BS 9999 and the Fire Door Inspection Scheme approach.

Common mistake to avoid: Skipping the identification step; Vague findings without photos
