At most risk are workers who are poorly hydrated, unacclimatized, or physically unfit. |
Our unacclimatized participants showed reduced peripheral capillary SpO2 and increased HR in the chamber. |
In comparison, all else seemed almost Arctic, unacclimatized. |
Unacclimatized humans experience extreme eye and nasal irritation at concentrations in excess of 25 ppm, and conjunctivitis from concentrations below 10 ppm has been reported. |
