What an induction actually covers
A site induction communicates the rules: where to park, how to sign in, emergency procedures, restricted zones, personal protective equipment, traffic routes and who to contact. It is essential and it makes the site safer for everyone present. What it does not do is qualify anyone for a controlled activity, because it is a briefing rather than a training course in a specific discipline.
That distinction matters when a request is made on the day. A supervisor who has seen the cleaning team complete an induction may reasonably assume they can be asked to help with something outside the scope. The correct answer is still no, and it is easier to give when the proposal already lists the exclusions rather than requiring the discussion to happen from scratch at the loading dock.
