In my experience, the items referred to as smoke detectors in residential housing, specifically in the kitchens are heat detectors. Heat detectors are singularly useless in a fire because the smoke will kill first (Villagio being an example of the cause of death).

The OP does not mention his employer - again, in my experience, the multi-national oil and gas and engineering firms do as you say Bachus and pull their people out of unsafe construction. Mine does not which is why I keep meticulous records should injury or death necessitate a lawsuit.

Which is why I insist on being on the first floor so I have a chance to save myself.
