Title Physical work limits for Toronto firefighters in warm environments
Bibliographic information Apr. 2004, Vol.1, No.4, p.199-212. Illus. 49 ref.
Abstract This study examined the relationship between tolerance time and metabolic rate for three different environmental temperatures (25░C, 30░C, and 35░C, 50% relative humidity) in a group of firefighters wearing firefighting protective clothing (FPC) and self-contained breathing apparatus (SCBA). Thirty-seven firefighters (33 male and four female) were divided into four work groups defined as heavy, moderate, light and very light according to the strenuousness of a treadmill exercise performed while wearing FPC and SCBA. Findings show the differential impact of environmental conditions at various metabolic rates on tolerance time. Results reveal that passive recovery may not be sufficient to reduce body temperature below pre-recovery levels when working at higher metabolic rates in hot environments.
