Surface Temperature Safety

Insulation does more than save energy. On hot pipes and vessels it also protects people from burns, and that protection is a legal requirement in its own right, sometimes demanding more insulation than the energy economics alone would justify. Where energy and safety point the same way, which is usually, insulating a hot surface saves money and makes it safe to touch. But where they diverge, safety is the hard constraint that wins. This lesson covers the burn risk, the safe-touch standard, and what to do when safety drives the thickness.
