In a perfect world, we could all work in weather-controlled environments where heat wouldn’t be a factor and comfort could be maximized. Many workplaces however, deal with very high temperatures and heat stress is a year-round risk that requires serious consideration. For many years the standards addressing the prevention of heat stress-related issues went untouched. Recently the National Institute of Occupational Safety and Health (NIOSH) released an evaluation of the available data on this subject (criteria for a recommended standard), with the goal of setting a new standard. The report; Occupational Exposure to Heat and Hot Environments, contains detailed information to aid employers, managers and workers in managing the occurrence of heat stress.
