This study investigated the physiological responses to different respirator types during various activities in a hot and humid environment, simulating conditions faced by grain handling workers. The type of respirator worn did not significantly impact heart rate, skin temperature, or core body temperature. While we found no significant differences in physiological responses between respirator types, there were clear differences in participant preferences. The strong preference for the Powered Air Purifying Respirator (PAPR) suggests that perceived comfort may be influenced by factors not captured in our physiological measurements, such as breathability or facial temperature. Additionally, the cooling effect of air being blown across the face by the PAPR likely contributed to its top selection among participants.
