Remember: Physical labor increases the heat experienced by workers. They should know that workers may experience heat stress at temperatures much lower than public heat advisories. Employers should be aware of any heat advisories from the National Weather Service. This step allows employers to determine if the work conditions are too hot. To determine workers' total heat stress, employers must assess both of the above heat sources.Įmployers should compare the total heat stress to published occupational heat guidance. Metabolic heat, generated by the body, is related to workload (physical activity).Environmental heat is produced by warm or hot surroundings.Two heat sources contribute to the risk of heat-related illness. Heat-related illness prevention starts by determining if a heat hazard is present in the workplace. You should consider the above factors when evaluating heat stress risk to workers. Common values given for categories of work are included in the table on Workload. Workload considerations are described at length in the OSHA Technical Manual.
