Wearing chemical protective suits (CPSs) involves the danger of heat stress. At normal protection levels, CPSs combining water vapor and air perme- ability with NBC-filter characteristics (permeable CPSs = PCPSs) may be able to reduce heat stress. At high protection levels, impermeable chemical protective suits (ICPSs) that lead to a high heat stress are indispensable.
