Heat stress is a serious challenge that poses immediate and long-term health effects for workers in high-temperature environments. As temperatures rise, so does the risk of harmful conditions like heat exhaustion and heat stroke. In a survey on occupational injuries by the Bureau of Labor Statistics (BLS), it was estimated that 33,890 work-related heat injuries and illnesses resulted in days away from work between 2011 and 2020, an average of 3,389 incidents per year (OSHA, 2024). The impact of heat exposure is also reflected in 999 fatalities from 1992-2021, averaging 33 deaths annually, according to the BLS Census of Fatal Occupational Injuries (OSHA, 2024).

Employers and Safety Managers play a critical role in combatting heat stress by educating workers on symptoms, encouraging breaks, ensuring access to water, and providing PPE that offers both safety and comfort.

What is Heat Stress?

Heat stress occurs when the body can no longer regulate its internal temperature effectively, causing a buildup of heat that overwhelms its cooling mechanisms. It commonly arises in environments with high air temperatures, humidity, and physical exertion, ultimately impairing the body’s ability to dissipate heat.

Early signs of heat stress may include mild fatigue, cramping, or dizziness. Prolonged exposure to high temperatures can lead to decreased performance, reduced focus, and a higher risk of accidents, as well as more serious injuries.

Choosing PPE with the appropriate level of heat resistance is essential for workers’ safety, ensuring they stay prepared and protected in demanding high-temperature environments.

How PPE Can Combat Heat Stress

PPE is essential for protecting against safety hazards such as sharp objects and chemicals, but it’s equally important for mitigating heat stress in hot environments. Selecting the right PPE can help workers maintain comfort and minimize heat-related risks.

Equipment that is lightweight, breathable, and designed for high-temperature applications is essential. These features help control temperature, prevent overheating, and manage moisture to keep the hands dry.

Wearing the wrong equipment, like heavily insulated gear, can increase the risk of heat stress. That’s why it's essential for employers and safety managers to select PPE tailored to the demands of their work environment. Our AlphaTec® CFR4000 Bodysuits and AlphaTec® 58-201 Gloves offer excellent protection without excessive insulation, helping to mitigate heat stress while maintaining safety:

These solutions from our AlphaTec® portfolio deliver reliable protection, keeping workers safe and comfortable. The optimized body fit design of the AlphaTec® CFR4000 offers improved wearer comfort and safety. Thanks to their acrylic liner, the AlphaTec® 58-201 green safety gloves deliver warmth in cold environments and delay heat transfer in contact heat applications.

Proactive Measures for Employers

To mitigate the risks of heat stress and ensure worker safety, employers should take the following measures:

• Educate Workers: Provide comprehensive training on recognizing heat stress symptoms and prevention techniques.
• Encourage Regular Breaks: Schedule rest periods in shaded or cooled areas to prevent overheating.
• Ensure Hydration: Supply ample water and electrolyte solutions at work sites.
• Choose the Right PPE: Select lightweight, breathable gear designed for high-temperature environments, such as the AlphaTec® 58-201 Gloves and CFR4000 Bodysuit.

By implementing these strategies, employers can create safer, more productive work environments and reduce the incidence of heat-related illnesses and injuries.
