<br />1.0 INTRODUCTION
<br />The purpose of this operating procedure is to provide general information on heat stress and the methods that can be utilized to prevent or minimize the
<br />occurrence of heat stress. Adverse climatic conditions must be considered when planning and conducting site operations. Ambient temperature effects can
<br />include physical discomfort, reduced efficiency, personal injury, decreased response time, and increased accident probability.
<br />1.1 TYPES OF HEAT STRESS
<br />If the body's physiological processes fail to maintain a normal body temperature because of excessive heat, a number of physical reactions can occur ranging
<br />from mild (such as fatigue, irritability, anxiety, and decreased concentration, dexterity, or movement) to fatal. Because heat stress is one of the most common
<br />and potentially serious illnesses that threaten employees at project field sites, regular monitoring and other preventative measures are vital. Site workers must
<br />learn to recognize and treat the various forms of heat stress.
<br />The best approach is preventive heat stress management. In general many or all of the following are guidelines to prevent heat stress
<br />• Have workers drink 16 ounces of water before beginning work, such as in the morning or after lunch. Provide disposable 4 ounce cups, and water that
<br />is maintained at 50-600F. Urge workers to drink 1-2 of these cups of water every 20 minutes, for a total of 1-2 gallons per day. Provide a cool,
<br />preferable air-conditioned area for rest breaks. Discourage the use of alcohol in non -working hours, and discourage the intake of coffee during
<br />working hours as these may increase water loss from body. Monitor for signs of heat stress;
<br />• Acclimate workers to site work conditions by slowly increasing workloads, i.e., do not begin site work activities with extremely demanding activities;
<br />• Provide cooling devices to aid natural body ventilation. These devices, however, add weight, and their use should be balanced against worker
<br />efficiency. An example of cooling aid is long cotton underwear which acts as a wick to help absorb moisture and protect the skin from direct contact
<br />with heat -absorbing protective clothing;
<br />• Install mobile showers and/or hose -down facilities to reduce body temperature and cool protective clothing;
<br />• In hot weather, conduct field activities in the early morning or evening;
<br />• Ensure that adequate shelter is available to protect personnel against heat, as well as cold, rain, snow, etc., which can decrease physical efficiency
<br />and increase the probability of both heat and cold stress. If possible, set up a rest area in the shade;
<br />• In hot weather, rotate shifts of workers wearing impervious clothing;
