California Department of Industrial Relations Division of Occupational Safety & Health Publications Unit SAFETY & HEALTH | FACT SHEET STATE OF CALIFORNIA CAL OSHA DEPARTMENT OF INDUSTRIAL RELATIONS # Heat Illness Prevention in Indoor Workplaces Information for Employers California Code of Regulations, title 8, section 3396 establishes required safety measures for indoor places of employment to prevent employee exposure to risk of heat illness. The standard applies to most workplaces where the indoor temperature reaches 82°F. This regulation requires employers to provide access to drinking water and cool-down areas, closely observe employees during acclimatization, train employees, and provide timely emergency aid. This fact sheet provides an overview-not all the requirements of section 3396. Please read the regulation for full requirements. ## Why should employers be concerned about indoor heat illness prevention? Many employees in indoor settings such as factories, food trucks, kitchens, warehouses, and foundries work in hot environments and are often unable to take advantage of heat illness prevention policies that apply to their counterparts working in outdoor places of employment. Heat illness is a serious medical condition resulting from the body's inability to cope with a particular heat load. Types of heat illness include heat cramps, heat exhaustion, heat syncope, and heat stroke, which can lead to death. ## Signs of heat stress The longer a person goes without assistance in excessive heat, the more likely they are to become seriously ill. Some symptoms of heat illness include the following: • Headache • Fatigue • Dizziness · Confusion · Muscle pain and spasms • Elevated heart rate • Heavy sweating • Hot/dry skin • Nausea/vomiting - Fainting/unconsciousness Certain medical conditions are risk factors of heat stress and related heat illnesses. Employees with heart disease or high blood pressure and those taking certain medications sh…

# Protecting Workers from the Effects of Heat (cont.) ## What is Heat Illness? (cont.) South Carolina OSHA Occupational Safety and Health Administration South Carolina Department of Labor, Licensing and Regulation Heat Rash is the most common problem in hot work environments. Heat rash is caused by sweating and looks like a red cluster of pimples or small blisters. Heat rash may appear on the neck, upper chest, groin, under the breasts and elbow creases. The best treatment for heat rash is to provide a cooler, less humid work environment. The rash area should be kept dry. Powder may be applied to increase comfort. Ointments and creams should not be used on a heat rash. Anything that makes the skin warm or moist may make the rash worse ## Occupational Factors that May Contribute to Heat Illness • High temperature and humidity • Low fluid consumption • Direct sun exposure (with no shade) or extreme heat • Limited air movement (no breeze or wind) • Physical exertion • Use of bulky protective clothing and equipment For more information, visit: https://osha.llr.sc.gov # PREVENTION MADE EASY ## Program Elements Heat Illness Prevention Program Key elements include: • A Person Designated to Oversee the Heat Illness Prevention Program • Hazard Identification • Water. Rest. Shade Message • Acclimatization • Modified Work Schedules • Training • Monitoring for Signs and Symptoms - Emergency Planning and Response ## Designate a Person to Oversee the Heat Stress Program Identify someone trained in the hazards, physiological responses to heat, and controls. This person can develop, implement and manage the program. ## Hazard Identification Hazard identification involves recognizing heat hazards and the risk of heat illness due to high temperature, humidity, sun and other thermal exposures, work demands, clothing or PPE and personal risk factors. Identification tools include: OSHA's Heat Smartphone App; a Wet Bulb Globe Thermometer (WBGT) which is a…

# 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…

# Heat Illness Prevention in Indoor Workplaces Information for Employers (cont.) ## What must employers do? Access to clean drinking water: Employers are required to provide access to potable water that is fresh, suitably cool, and free of charge. It must be located as close as practicable to the work area and cooling area. If an employer does not provide plumbed water, they are required to provide at least one quart per hour per employee per shift. Employers must encourage frequent water consumption. Cool-down areas and rest periods: Employers must provide access to at least one cool-down area which must be maintained at a temperature below 82°F, blocked from direct sunlight, shielded from other high-radiant heat sources, large enough to accommodate the number of employees on rest breaks, and as close as practicable to the work area. They must allow employees who ask for a cool-down rest period to take one. In addition, employers must encourage employees to take preventative cool-down rest periods and monitor employees taking such rest periods for symptoms of heat-related illness. If symptoms persist, they may not be ordered back to work. Assessing and measuring heat: Employers must measure the temperature and heat index and record whichever is greater whenever the temperature or heat index reaches 87°F (or temperature reaches 82°F for employees working in clothing that restricts heat removal or high radiant heat areas). This is an important step to ensure that employers know when to implement control measures to keep employees safe. Emergency response procedures: Employers must provide first aid or emergency response to any workers showing heat illness signs or symptoms, including contacting emergency medical services. Acclimatization: Employers must closely observe new employees and newly assigned employees working in hot areas during a 14-day acclimatization period, as well as all employees working during a heat wave where no effective engineering controls…

# Subject: Enforcement Guidelines for Outdoor Exposure to Heat Stress (cont.) ## Background (cont.) MNOSHA Instruction STD 1-4.2A March 1, 2021 The State of Washington has an outdoor heat exposure standard which applies from May 1 through September 30. Drinking water must be available in an amount not less than one quart per employee per hour. Training is required. According to the California OSHA standard, water must be available as close as practicable to the areas where employees are working at least one quart per employee per hour (when not plumbed). Shade must be provided when the temperature exceeds 80 degrees F and employees allowed to take a rest in the shade. When temperatures exceed 95 degrees F, further procedures must be implemented to monitor employees for signs or symptoms of heat illness, including a buddy system. Training and acclimatization is also included in the Cal/OSHA standard. ## Action ## A. Inspection Guidelines 1. OSHIS shall evaluate the working conditions for possible heat exposure hazards. 2. The questionnaire in Appendix B of this directive may be used as a guide to assess the conditions and precautions taken by the employer. ## B. Citation Guidelines - A violation of the general duty clause may exist in these conditions when workers have been working outdoors and their employer is aware of heat-related dangers but has not taken action to provide workers with, at a minimum, water, rest, and shade. To establish the evidence necessary to cite a general duty clause violation, the following information should be documented. - NOTE: These examples represent some types of evidence that could establish each of the factors; they are not the only types that would satisfy OSHA's burden): 1. The employer failed to keep the workplace free of a hazard to which its employees were exposed: a.

# 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, …
