Elevated core body temperatures may cause the following illnesses: When these are not enough to keep the core body temperature from rising, the result is heat-related illness or death. The body's natural way to keep the core body temperature from rising to unhealthy levels is through an increase in heart rate and sweating. Heat Strain – The body's physiological response to heat stress (e.g., sweating). Physical exertion, environmental factors, and clothing worn all contribute to heat stress. Heat Stress – The net heat load to which a worker is exposed. The terms heat stress and heat strain represent the relationship and difference between external factors and the body's core temperature control mechanisms: This process may become self-sustaining and generate a run-away inflammatory response, the "systemic inflammatory response" syndrome that often leads to death. As core temperature continues to increase, the body releases inflammatory agents associated with damage to the liver and muscles. As core temperature rises, the body is less able to perform normal functions. A heat-related illness occurs when there is an increase in the worker's core body temperature above healthy levels. Many risk factors contribute to the risk for heat-related illness (see Figure 1.). Heat-related illness risk factorsĪlthough heat hazards are common in indoor and outdoor work environments, heat-related illness and fatalities are preventable. Although heat-related illness prevention programs are referenced in this OTM chapter, the chapter is not a guide for developing a program.įigure 1. In February 2016, the National Institute for Occupational Safety and Health (NIOSH) published the Criteria for a Recommended Standard: Occupational Exposure to Heat and Hot Environments, a technical resource on heat stress, heat-related illness signs and symptoms, and heat programs. Specifically, this chapter provides technical information about using Wet Bulb Globe Temperature (WBGT) measurements to determine when heat exposure hazards are present in the workplace. The information will help to prepare OSHA compliance officers to conduct inspections and investigations. This OSHA Technical Manual (OTM) chapter provides technical information about indoor and outdoor heat hazards, illnesses, and prevention methods across all industries. Assessing worker exposure in conditions that may present a heat hazard is critical for knowing when to implement a heat-related illness prevention program. Heat-related fatality cases show that workplaces with temperatures above 70 degrees Fahrenheit may have a heat hazard present when work activities are at or above a moderate workload.
