Flame-resistant (FR) clothing is crucial for workers in high-risk industries such as oil and gas, electrical utilities, and manufacturing. However, working in hot and humid conditions while wearing FR apparel presents challenges. Excessive heat exposure can lead to fatigue, dehydration, and heat-related illnesses, making it essential to choose FR clothing that provides both protection and comfort.
Understanding FR Clothing and Its Importance
FR clothing is designed to self-extinguish when exposed to flames, reducing the severity of burn injuries. Unlike standard clothing, FR garments prevent ignition, minimize heat transfer, and offer protection against electric arc flashes and flash fires. Regulations such as OSHA 1910.269 and NFPA 70E mandate the use of FR clothing in hazardous work environments, making compliance a necessity.
During summer, the challenge is balancing protection with comfort. Heat stress is a real concern, and improper clothing choices can exacerbate the risks of overheating. Fortunately, advancements in fabric technology and design improvements have led to the development of lightweight ...
... and breathable FR garments suitable for hot weather conditions.
Key Features to Look for in Summer FR Clothing
1. Lightweight and Breathable Fabrics
The weight of FR clothing is measured in ounces per square yard (oz/yd²). In hot climates, selecting garments in the 4.5-6.5 oz/yd² range can enhance comfort while maintaining protection. Recommended lightweight FR fabric options include:

Modacrylic Blends – Inherently flame-resistant, soft, and breathable.
Treated Cotton – Offers a balance of comfort and protection but may retain more heat than synthetic blends.
Aramid Blends – Durable and lightweight, commonly used in FR work shirts and coveralls.

2. Moisture-Wicking and Quick-Dry Technology
Sweat accumulation can be a major issue in FR clothing. Choosing garments with moisture-wicking properties ensures that sweat is drawn away from the body and dries quickly, preventing discomfort and reducing the risk of overheating. Some advanced FR materials incorporate hydrophilic and hydrophobic fibers to enhance moisture management.
3. Ventilated and Mesh-Enhanced Designs
To promote airflow, many manufacturers now offer FR clothing with vented backs, underarm mesh panels, and perforated fabric sections. These features enhance breathability while maintaining compliance with safety standards.
4. Lighter Colors for Heat Reflection
Dark colors absorb more heat, making them less suitable for summer use. Opting for light-colored FR clothing, such as beige, light gray, or khaki, helps reflect sunlight and keeps the body cooler.
5. Proper Fit and Layering Strategy
A snug yet comfortable fit ensures optimal performance of FR clothing. Loose-fitting garments allow better airflow but should not be excessively baggy, as this may pose safety hazards. Layering with lightweight FR base layers can help wick moisture while maintaining protection.
Workplace Strategies for Managing Heat Stress
Aside from choosing the right FR clothing, implementing heat management strategies in the workplace is essential.
1. Hydration Protocols
Workers should be encouraged to drink water frequently, ideally 8-10 ounces every 15-20 minutes. Electrolyte-replenishing drinks can also be beneficial, but caffeine and sugary beverages should be avoided as they contribute to dehydration.
2. Scheduled Breaks and Shade Access
Employers should ensure that workers take regular breaks in shaded or air-conditioned areas to prevent heat-related illnesses. Scheduling heavy labor-intensive tasks during cooler parts of the day, such as early mornings or late afternoons, can also help.
3. Use of Cooling Accessories
FR-compliant cooling accessories such as cooling towels, bandanas, and moisture-wicking headgear can significantly enhance comfort in hot environments.
4. Heat Stress Monitoring
Employers should implement heat stress monitoring programs, including training workers to recognize early signs of heat exhaustion, such as dizziness, nausea, and excessive sweating. Using wearable temperature sensors can also help track body temperature and prevent heatstroke.
Regulatory Compliance and Safety Considerations
While staying cool is important, safety should never be compromised. All FR clothing must meet industry safety standards, including:

NFPA 2112 – Standard for flame-resistant garments for industrial personnel.
ASTM F1506 – Standard performance specification for flame-resistant textile materials.
OSHA 1910.269 – Regulations regarding FR clothing requirements in electric power generation and transmission.

Employers must ensure that FR clothing used in hot conditions is still compliant with these regulations and provides adequate protection in case of an incident.
Working in extreme heat while wearing FR clothing presents unique challenges, but with the right fabric choices, moisture-wicking technologies, and workplace strategies, workers can stay cool while remaining protected. Lightweight, breathable, and moisture-wicking FR garments, combined with proper hydration and heat stress management, can significantly improve comfort and safety during the summer months. Employers must prioritize both compliance and worker well-being to create a safer and more efficient work environment. By making informed choices, workers can ensure that they are not only protected from fire hazards but also from the dangers of heat stress in high-temperature workplaces.
