I recently visited a school, within the boiler room there is a carbon monoxide detector built into the system which is installed at a low level around 900 from floor level. My understanding is (CO) is slightly lighter than air, so carbon monoxide alarms are effective when placed on the ceiling or high up on a wall. I would appreciate your advice on this point ?
The other point I noted there was no fire detection in the boiler areas. In the vast majority of the school there is no fire detection , there are call points throughout the school, there are some detectors
