Good afternoon all I started in a new role a few weeks ago and some of the labs are quite old and are made up of rows of freestanding benches. In the middle of each row is a fixed section where the gas taps come out from. Yesterday I walked into a lab to see two boys jostling, the bunsen was lit on the bench in front of them. The jostling caused the table to be pushed, and the burner started to slide towards the edge. Thankfully the table righted itself but I had visions of the bunsen falling off the edge of the bench. I know there was some guidance on Cleapss a while ago for benches that were loose, but that was concerns regards damaging the piping, my concern in this case is bunsens sliding off the bench. (I'm aware its a behaviour issue and they shouldn't be messing about in labs) I mentioned it to the class teacher at the time and again after her lesson, but what else should I do? I will of course mention it to the HOD but I feel it'll go in one ear out the other and will resent me causing him more work (I can imagine he'll say they've never had a problem before..) I'm not overreacting am I?
