Reproductive hazards of fire fighting I. Non‐chemical hazards

Fire fighters are regularly exposed to chemical and non‐chemical agents that have known or suspected adverse effects on reproductive health. Although chemical agents have received some attention, non‐chemical hazards such as heat, noise, and physical exertion have only recently been examined for their reproductive effects. There is evidence that heat, noise, and physical exertion may affect various endpoints of reproductive health, including fertility, fetal loss, and growth parameters of the offspring. In particular, hyperthermia, a major fire fighting hazard, has been shown to impair male fertility and may also be teratogenic. Further study of the potential reproductive effects of this and other common non‐chemical agents in the fire environment is needed to ensure the reproductive health of male and female fire fighters.
