What temperature may the PBE hood reach during use?

Explanation:
Heat inside the PBE hood comes from the exothermic chemical oxygen generator and the sealed hood trapping some of that warmth. During use, the air inside can rise to about 102 °F, a warm but safe level for the wearer for the duration of the oxygen supply. This is higher than normal body temperature but not extreme; the other temperatures listed are either normal body temp, too cool, or uncharacteristically hot for standard PBE operation. Knowing this helps you anticipate the sensation you’ll feel when the hood is on, without expecting it to be like a very hot environment.
