102 . 3 ADDITIONAL HAZARD <br /> The use of Personal Protective Equipment of the types <br /> commonly used for hazardous waste work can place stress on the <br /> body. One common problem with the use of personal protective <br /> equipment, especially in hot environments, is heat stress. <br /> Protective clothing can cause excessive sweating and can prevent <br /> the body from properly regulating body temperature. <br /> 102 . 4 TYPES OF HEAT STRESS <br /> Heat stress is the aggregate of environmental and <br /> physical work factors that constitute the total heat load imposed <br /> on the body. The environmental factors of heat stress are the air <br /> temperature , radiant heat exchange, air movement, and water vapor <br /> pressure . Physical work contributes to the total heat stress of <br /> the job by producing metabolic heat in the body in proportion to <br /> the intensity of the work. The amount and type of clothing also <br /> affect the heat stress . <br /> Heat strain is the series of physiological responses to <br /> heat stress . When the strain is excessive for the exposed <br /> individual , a feeling of discomfort or distress may result, and, <br /> finally , a heat disorder may ensue. The severity of strain will <br /> depend not only on the magnitude of the prevailing stress, but also <br /> on the age , physical fitness, degree of acclimatization, and <br /> dehydration of the worker. <br /> Heat disorder is a general term used to describe one or <br /> more of the following heat-related disabilities or illnesses: <br /> o Heat Cramps - painful intermittent spasms of the <br /> voluntary muscles following hard physical work in a hot <br /> D797 . 8/72 HS-102-2 November 1990 <br />
