# HEAT EXHAUSTION Last Review: 08/01/2025 Date Posted: 09/09/2016 Working in the heat and doing heavy physical work can affect the body's cooling system. If your body is unable to cool itself, you can experience heat stress. If heat stress is not treated, it can develop into heat stroke, which can result in death. Heat Exposure applies to outdoor work environments from May 1 through September 30, when employees are exposed to outdoor heat at or above an applicable temperature listed in Table 1. WAC 296-62-[redacted postal code]. Remember, heat exposure can happen anytime of the year, as well as indoors. ## SIGNS AND SYMPTOMS • Shallow breathing • Increased breathing rate • Weak, rapid pulse • Cool, pale, clammy skin • Sweating • Weakness, fatigue, dizziness • Headache and nausea - Fainting • Muscle cramps ## TREATMENT • Move the worker to a cooler environment. If possible, lay the worker down, and remove or loosen tight-fitting clothing. • Cool the worker by sponging with cool water and fanning. Take care not to cool the worker too much. If the worker begins to shiver, stop cooling. - In most cases, the patient's symptoms will improve dramatically within 30 minutes. - Call 911 immediately if there are signs of Heat Stroke (confusion, agitation, absence of sweating or loss of consciousness). ## PREVENTION • - Acclimatize your body (gradually expose yourself to warmer work environments). • Drink plenty of water (one glass every 20 minutes). • Wear clean, light-colored, loose-fitting clothing made of breathable fabric. • Take rest breaks in a cool or well-ventilated area. • Take more breaks during the hottest part of the day or when doing hard physical work. Allow your body to cool down before beginning again. • Take care not to burn. This can occur in as little as 10 minutes • If desired, apply high factor sun-screen generously and frequently to any parts of the body exposed to the sun; SPF15 or above • Remember to - hydrate before yo…

# HEAT-RELATED HAZARDS & CONTROLS Date Posted: 02/17/2024 Workers exposed to extreme heat or working in hot environments may be at risk of heat stress. Exposure to extreme heat can result in occupational illnesses and injuries. For example, heat stress can result in heat-related illnesses such as heat stroke, heat exhaustion, heat cramps, or heat rashes. Heat can also increase the risk of traumatic injuries as it may result in poor grip, fogged-up safety glasses, and problems with balance. According to the Bureau of Labor Statistics (BLS), high temperatures can be dangerous to people at work and can lead to injuries, illnesses, and even death. Exposure to environmental heat led to 37 work-related deaths and 2,830 nonfatal occupational injuries and illnesses involving days away from work in 2020. Thirty-three of the 37 fatal work injuries caused by exposure to environmental heat occurred in the summer months of June through September. On June 27, 2023, the Washington State Department of Labor & Industries (L&I) adopted updates to Outdoor Heat Exposure rules to prevent heat- related illness and reduce traumatic injuries associated with heat exposure. The adopted rules include requirements for shade, rest, and acclimatization and lowers the temperatures at which some preventive actions must be taken. ## WASHINGTON STATE ACTION LEVELS Clothing/PPE Worn Action Level Temperature Nonbreathing clothing, including vapor-barrier clothing or chemical-resistant suits 52° All other clothing 80° ## THE IMPORTANCE OF ACCLIMATIZATION Workers are at higher risk of heat-related illness if they are not acclimatized or used to the heat. Acclimatization typically takes 7-14 days to develop and can be lost after seven days away from working in the heat. A sudden increase in temperature does not allow time for workers to acclimate. Acclimatization is a process by which the physical processes of a worker's body adjust to the environment over some time. Based on data obtained from…

PROTECT YOUR WORKERS FROM HEAT STRESS ## Develop an acclimatization plan Acclimatization is the result of beneficial physiological adaptations (e.g., increased sweating efficiency and stabilization of the circulation) that occur after gradual increased exposure to a hot environment. TIP 1 TIP 2 Gradually increase the time spent in hot environmental conditions over a 7-14 day period. For new workers, the schedule should be no more than 20% exposure to heat on day 1 and an increase of no more than 20% exposure on each additional day. ## TIP 3 ✓ they don't have heat-related symptoms. For workers who have had previous experience with the job, the acclimatization schedule should be no more than: <table><tr><th>DAY 1</th><th>DAY 2</th><th>DAY 3</th><th>DAY 4</th></tr><tr><td>50%</td><td>60%</td><td>80%</td><td>100%</td></tr><tr><td>EXPOSURE</td><td>EXPOSURE</td><td>EXPOSURE</td><td>EXPOSURE</td></tr></table> ## Set up a buddy system Check your workers routinely to make sure... - they make use of readily available water and shade. ## Schedule and encourage frequent rest breaks... ...with water breaks in shaded or air-conditioned recovery areas. ## Emphasize the need for appropriate clothing Encourage workers to wear clothing that is... light-colored breathable - loose-fitting ## Encourage workers to drink plenty of fluids... ...such as drinking small amounts of water before becoming thirsty.

# Heat Stress and Working in Hot Conditions (cont.) - Hallucinations * Chills - Throbbing headache - High body temperature - Confusion/dizziness - Slurred speech ## Take the following steps to treat a worker with heat stroke: - Call 911 and notify the worker's supervisor. - Move the sick worker to a cool shaded area. ✡ Cool the worker using methods such as: - Soaking the worker's clothes with water. - Spraying, sponging or showering the worker with water. - Fanning the worker's body. Heat exhaustion is the body's response to an excessive loss of the water and salt, usually through excessive sweating. Workers most prone to heat exhaustion are those who are elderly, those who have high blood pressure, and those working in a hot environment. ## Symptoms of heat exhaustion include: - Heavy sweating - Extreme weakness or fatigue - Dizziness, confusion * Nausea - Clammy, moist skin - Pale or flushed complexion - Muscle cramps - Slightly elevated body temperature - Fast and shallow breathing - Take the following steps to treat a worker with heat exhaustion: - Have the worker rest in a cool, shaded or air-conditioned area. - Have the worker drink plenty of water or other cool, non- alcoholic beverages. - Have the worker take a cool shower, bath or sponge bath. A good heat-related illness prevention program would likely contain the following elements; however, each work environment or situation may not require all elements. 1. Responsibilities of the employer and employees regarding working in hot, humid environments. 2. Environmental factors and personal health factors that contribute to heat-related illnesses. 3. Procedures for measuring air temperature and documenting effects of other environmental factors (humidity, wind strength, work location) by determining the wet bulb globe tem- perature (WBGT) index or heat index using any tool or resource available, including the OSHA Heat Safety Tool smart phone…

# PREVENTION MADE EASY (cont.) ## Hazard Identification (cont.) South Carolina OSHA Occupational Safety and Health Administration South Carolina Department of Labor, Licensing and Regulation ## Water. Rest. Shade Ensure that cool drinking water is available and easily accessible. (Note: Certain beverages, such as caffeine and alcohol can lead to dehydration.) Encourage workers to drink a liter of water over one hour, which is about one cup every fifteen minutes. Provide or ensure that fully shaded or air- conditioned areas are available for resting and cooling down. ## Acclimatization Acclimatization is a physical change that allows the body to build a tolerance to working in the heat. It occurs by gradually increasing workloads and exposure and taking frequent breaks for water and rest in the shade. Full acclimatization may take up to 14 days or longer depending on factors relating to the individual, such as increased risk of heat illness due to certain medications or medical conditions, or the environment. New workers and those returning from a prolonged absence should begin with 20% of the workload on the first day, increasing incrementally by no more than 20% each subsequent day. During a rapid change leading to excessively hot weather or conditions such as a heatwave, even experienced workers should begin on the first day of work in excessive heat with 50% of the normal workload and time spent in the hot environment, 60% on the second day, 80% on day three, and 100% on the fourth day For more information, visit: https://osha.llr.sc.gov # Modified Work Schedules Altering work schedules may reduce workers' exposure to heat. For instance: - Reschedule all non-essential outdoor work for days with a reduced heat index. • Schedule the more physically demanding work during the cooler times of day; • Schedule less physically demanding work during warmer times of the day; • Rotate workers and split shifts, and/or add extra workers. • Work/Rest cycles, …

CPWR TOOLBOX RESEARCH AND TRAINING THE CENTER FOR CONSTRUCTION TALK Hot Environments Exposure to extreme heat can result in illness and injury. Working in a hot environment can cause heat stroke, heat exhaustion, heat cramps, or heat rash. In addition, heat increases the risk of injury for workers because of sweaty palms, fogged-up safety glasses, and dizziness. Burns also can occur when a worker comes in contact with a hot surface or steam. ## Ben's Story Ben had been outside for several hours in extremely hot temperatures laying brick. He began to feel nauseated, his head ached, and he was sweating heavily. His supervisor noticed Ben was working much slower than usual and asked him how he felt. When he heard the symptoms, he called 911, took Ben to the shade, gave him a cool drink, and wetted him with cool water and ice. - Have you or someone you know ever experienced a heat-related illness on the job? If so, what happened? - What can you do to help avoid heat-related illnesses? ## Remember This ➤ Your employers should train you on heat hazards and their plan to prevent heat-related illnesses. - Take frequent breaks in the shade or in air conditioning. - Drink plenty of water - stay hydrated.
