What is a fire safety log book?
A fire safety log book is the record of everything done to keep a building fire safe — alarm tests, equipment checks, drills, training, defects and their closure. It is the evidence the duty was met.

</figure>The log is what turns activity into evidence. Work done and not recorded is, to an inspecting officer, indistinguishable from work not done, and reconstructing it afterwards is both unconvincing and obvious.
Its value is in being continuous. A complete record for the last three months and nothing before it tells a clearer story than the person presenting it usually intends.
It needs to be available to whoever asks, which in practice means it needs to be findable by someone other than the person who maintains it.
In practice
A fire log book with an index and four empty sections.
The index lists what should be in it, which is what makes the gaps visible — and uncomfortable.
That discomfort is the entire function. A book without an index is a pile of whatever got filed, and a gap in it is invisible.
The sections most often empty are drills and training.
What goes wrong in practice
- Kept by one person, in one place, with no access for anyone else.
- Gaps over holidays and staff changes that nobody fills or explains.
- Entries signed with no detail of what was tested or found.
