Hi im working as a attic insulation installer and with the good weather we are having well had, the attics get very hot and I was wonder if anyone would know what heat degree are you allowed under health and safety regulations to work in.I am asking this as I was working in an attic a few days ago and I thought I got heat stroke,i also ended up with sores on my eyelids.I did ring my employer to tell them the temperature outside which was 30 degrees but I was told to finish the job.Thanks
