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 measure of heat stress in direct sunlight that takes into account temperature, humidity, wind speed, sun and cloud cover; and the National Weather Service Heat Index. Exposure to full sun can increase heat index values up to 15°F.
