As temperatures rise, so do the risks of heat stress for outdoor workers. Heat stress occurs when the body's internal temperature regulation mechanisms are overwhelmed by external heat. In this blog post, we help you understand what heat stress is, explore OSHA standards for heat stress prevention, discuss the risks involved, how to combat heat stress in the workplace and the different products that can help employees.

What is Heat Stress?

Heat stress is a serious condition that occurs when the body's core temperature rises to dangerous levels due to prolonged exposure to high temperatures and humidity. It can manifest in various forms, including heat rash, heat cramps, heat exhaustion, and heat stroke. These conditions can range from mild discomfort to life-threatening emergencies if left untreated.

OSHA Standards for Heat Stress

The Occupational Safety and Health Administration (OSHA) sets standards to protect workers from heat-related illnesses. The OSHA General Duty Clause requires employers to provide a safe working environment free from recognized hazards, including those related to extreme heat. OSHA provides guidelines and recommendations for employers to follow to prevent heat-related illnesses among their workers. You can find heat stress posters, infographics and more from OSHA, here.

Risks of Heat Stress for Employees

Employees exposed to high temperatures are at risk of experiencing various heat-related illnesses, which can impact their health, safety, and productivity. Some of the risks associated with heat stress include:

Dehydration: Prolonged exposure to heat can lead to excessive sweating and fluid loss, increasing the risk of dehydration. Dehydration can cause extreme thirst, dizziness and fatigue.

Heat Cramps: A muscle cramp is a sudden, unexpected tightening of one or more muscles. Muscle cramps are a common symptom of heat stress, resulting from electrolyte imbalances due to sweating.

Heat Exhaustion: Heat exhaustion happens when your body loses too much water and salt, typically from sweating. This condition causes symptoms such as dizziness, nausea, headache, and fatigue, and can progress to heat stroke if left untreated.

Heat Stroke: Heat stroke is a life-threatening emergency that occurs when the body's temperature regulation system fails, leading to a rapid rise in core body temperature. Symptoms include confusion, loss of consciousness, seizures, and it can permanently damage the brain, heart, kidneys, and other vital organs if untreated.

Preventing Heat Stress

Preventing heat stress requires a comprehensive approach that addresses both environmental and personal factors. Here are some strategies to help prevent heat-related illnesses in the workplace:

Stay Hydrated: Encourage employees to drink plenty of water throughout the day. Provide access to cool water sources and electrolyte-replenishing drinks to prevent dehydration.

Schedule Breaks: Implement regular breaks in shaded or air-conditioned areas to allow employees to rest and cool down. Rotate tasks to minimize exposure to heat, especially during the hottest parts of the day.

Provide Shade and Ventilation: Set up tents for shaded areas and use fans to improve air circulation in outdoor work areas. Consider installing misting systems or portable air conditioners for additional cooling.

Use Personal Cooling Products: Equip workers with cooling products such as cooling vests and evaporative cooling towels to help regulate body temperature. These products use advanced cooling technologies to provide relief in hot environments.

UV-Protection: Sunscreen and UV protective clothing helps shield the skin from harmful ultraviolet rays preventing sunburn and dehydration. Attachable hard hat shades can help protect from the sun and keep employees cool.

Heat stress is a significant occupational hazard that can pose serious risks to employee health and safety. By implementing OSHA guidelines and adopting preventive measures such as staying hydrated, taking breaks, and using appropriate cooling products, employers can help protect their workers from heat-related illnesses.
