Hi, I'm moving into a very old disused classroom that is being resurrected due to roll growth. The light fittings are 4 fluorescent lights, single tube, with no covers hanging down on chains from the ceiling. My question is, is this legal in terms of health and safety? The principal is just doing his best with no money. However with neurodiverse children being an ever increasing reality the potential for a ball or other object to smash the fluorescent tube above children working, is a hazard I can't discount. Is there a really cheap solution please, as I am considering using the small budget I have for resources to rather prioritise health and safety.
