Criteria for a Recommended Standard - Occupational Exposure to Hot Environments. Revised Criteria 1986

摘要

The recommended criteria were developed to ensure that adherence to them will (1) protect against the risk of heat-induced illnesses and unsafe acts, (2) be achievable by techniques that are valid, reproducible, and available, and (3) be attainable by existing techniques. The recommended standard is also designed to prevent possible harmful effects from interactions between heat and toxic chemical and physical agents. The recommended environmental limits for various intensities of physical work as indicated in figures 1 and 2 are not upper tolerance limits for heat exposure for all workers but rather levels at which engineering controls, preventive work and hygienic practices, and administrative or other control procedures should be implemented in order to reduce the risk of heat illnesses even in the least heat-tolerant workers.
