I don't know where to go with this question so if someone here can't help me, could you possibly direct me to a more appropriate forum. I belong to a gym and twice a week I do a cycling class. This takes place in a room with a lowish ceiling that holds 50 bikes. It is air conditioned but once the cycling starts, we can't feel it. The thing that gives us relief when the body temperature rises are 3 very large fans positioned in 3 of the corners. The management are going to take these fans away and people are really unhappy. Some of the cyclists sit right in front of the fans as they overheat very easily. I want to write a letter of complaint but I want to be able to add in any relevant comments that might indicate that this could be a health and safety issue. I have been researching the internet and I'm looking at something to do with the BTUs released by a number of bodies under extreme exercise in an enclosed area but everything is so scientific. I need something in plain English that might cause them to change their minds. Can you suggest anything? I am going away tomorrow for a week so if you post and hear nothing - that's why. Merry Christmas!
