According to the U.S. Department of Labor, the Occupational Safety and Health Administration (OSHA) sets federal standards for temperature and humidity levels in the workplace. However, there is no specific requirement for employers to maintain a certain workplace temperature under OSHA regulations. Instead, OSHA recommends that employers keep the thermostat between 68 and 78 degrees Fahrenheit to protect employees from having to work in uncomfortable temperatures. The minimum temperature for indoor workplaces is 68 degrees Fahrenheit, and the maximum is 76 degrees Fahrenheit. Employers must stick to health and safety at work law, including keeping the temperature at a comfortable level and providing clean and fresh air. The minimum temperature in an indoor workplace should normally be at least 16°C or 13°C if much of the work involves rigorous physical effort. However, there is no law for maximum working temperature or when its too hot to work because every workplace is different. Employers should take practical steps to protect workers in high or low temperatures, such as keeping work areas well-ventilated, using fans or air conditioners, relocating employees to cooler work spots, and providing cool rest areas for breaks.
