background: heat stress is one of the agents in the work environment that can create numerous problems for workers. the objective of this research is to study heat stress control in the foundry platform of a steel plant in tehran. methods: in this experimental study, controlling plans were demonstrated for the work conditions improvement in one of steel plant's foundry platforms. for controllin...

heat stress is a significant occupational health and safety for workers in petrochemical industries. heat stress is a combination of heat load individual and environmental factors impose on workers’ bodies, which in turn, have impacts on workers’ performance, safety, and health. the present paper is carried out to determine the heat stress levels in workplace and to compare it with allowed wet ...

This study consists of assessments of the thermal environment and physiological strain in tasks associated with airport, construction, and metal jobs. The number of male and female participants was 108. Environmental heat stress was evaluated with the WBGT index. Physiological strain was evaluated by the relative cardiovascular load (%CVL) based on the measurements of heart rate. Also the incre...

OBJECTIVE To examine whether non-heat acclimatized (NHA) emergency responders endure greater physiological and perceptual strain than heat acclimatized (HA) counterparts in tropical field settings. METHODS Eight HA and eight NHA men urban search and rescue personnel had physiological and perceptual responses compared during the initial 4 hours shift of a simulated disaster in tropical conditi...
