What are OSHA regulations regarding hot water in office building lavatories? I work in a very nice office building. The lavs are quite modern with self-flushing toilets and automatic faucets & paper towel dispensers. The problem is that with the automatic faucets (i.e. the unit senses your hands beneath the spout and turns water on) water has to run for a long time before any warm/hot water is dispensed. I recently waited 6 minutes for hot water to finally make it from the spout (and personally, I don't have 6 minutes to wait for hot water each time I use the lav). I contacted our facilities department who said they investigated. The problem was not corrected. In our current climate of illness and disease, and with the significant concerns around flu viruses, I want to have hot water to wash my hands after I use the bathroom. Is this a violation of OSHA regulations?
