Working in the electrical and utility industries often means facing two hazards at the same time: electrical risks and extreme heat. Whether you're performing substation maintenance, climbing utility poles, restoring power after storms, or working inside energized facilities, excessive heat can quickly impact comfort, productivity, and safety.
Heat stress contributes to fatigue, reduced concentration, dehydration, and increased risk of incidents. For utility crews and electrical workers already wearing flame-resistant (FR) clothing, arc flash PPE, and other protective equipment, managing body temperature becomes even more important.
Fortunately, modern cooling PPE solutions can help workers stay safer and more comfortable without compromising protection.
Why Heat Stress Is a Serious Concern for Utility Workers
Electrical and utility workers frequently perform physically demanding tasks while wearing multiple layers of protective clothing. FR garments, arc flash suits, hard hats, gloves, and other PPE create additional insulation that can trap body heat and limit airflow.
Common signs of heat stress include:
- Excessive sweating
- Dizziness or headaches
- Fatigue
- Muscle cramps
- Reduced alertness
- Heat exhaustion
OSHA recommends combining hydration, rest breaks, shade, and appropriate cooling gear to reduce heat-related illnesses. Cooling PPE serves as an important layer in a comprehensive heat stress prevention program.
Cooling Vests: The Front-Line Defense Against Heat
One of the most effective ways to reduce heat stress is by wearing a cooling vest beneath or over work apparel.
Cooling vests use evaporative cooling technology to help lower skin temperature and improve comfort throughout the workday. These products are especially useful for:
- Utility line crews
- Electrical contractors
- Solar installers
- Substation technicians
- Transmission and distribution workers
Novarlo offers evaporative cooling vest options that provide cooling relief while maintaining high-visibility compliance for workers exposed to roadway and utility hazards.
Moisture-Wicking FR Base Layers
Many workers assume adding layers increases heat. In reality, the right FR base layer can significantly improve comfort.
Modern moisture-wicking FR base layers:
- Pull sweat away from the skin
- Improve evaporation
- Reduce heat buildup inside arc flash clothing
- Improve comfort under FR shirts and coveralls
Unlike cotton undershirts that stay wet, moisture-wicking FR garments help regulate body temperature while maintaining arc flash and flame-resistant protection. Cooling apparel and moisture management technologies have become increasingly important for workers wearing FR clothing in hot environments.
Cooling Neck Wraps for Utility Crews
The neck is one of the body's most effective cooling zones. Keeping this area cool can provide immediate relief during hot summer shifts.
The Novarlo PVA Cooling Neck Wrap uses evaporative cooling technology to provide hours of cooling relief and can be easily reactivated throughout the day. Features include:
- Reusable design
- Lightweight PVA construction
- Quick activation in water
- Anti-microbial treatment
- Comfortable fit under hard hats and safety gear
For utility workers spending long hours outdoors, cooling neck wraps offer a simple and cost-effective heat stress solution.
Hard Hat Cooling Accessories and Neck Shades
Utility workers spend countless hours exposed to direct sunlight. Hard hats protect against impact hazards, but they can also trap heat.
Cooling neck shades and hard hat accessories provide several benefits:
- Increased shade coverage
- UV protection
- Cooling effect through evaporative materials
- Protection for the neck and ears
- Reduced sunburn risk
Many cooling neck shades attach directly to hard hats and help workers remain comfortable during extended outdoor work. Novarlo's cooling accessories utilize evaporative PVA technology to provide cooling relief while helping protect workers from solar exposure.
Lightweight FR Shirts Designed for Hot Weather
Heavy FR clothing isn't always necessary. Today's lightweight FR shirts are engineered to provide protection while maximizing breathability.
Look for:
- Moisture-wicking fabrics
- Lightweight fabric weights
- Ventilated construction
- Arc-rated protection
- High-visibility options
Utility workers can reduce heat buildup by selecting appropriate FR clothing systems that balance protection and comfort.
Cooling PPE for Storm Restoration Crews
Storm restoration work presents unique challenges. Crews often work:
- Long shifts
- High humidity
- Summer temperatures
- Emergency conditions
- Remote locations
A complete cooling strategy should include:
- Moisture-wicking FR base layers
- Cooling neck wraps
- Cooling vests
- Hard hat neck shades
- Frequent hydration
- Scheduled recovery periods
Combining multiple cooling solutions can dramatically improve worker comfort and endurance during emergency response operations.
How Cooling PPE Supports Safety Performance
Heat stress doesn't just affect comfort, it affects decision-making.
When workers become overheated, they may experience:
- Slower reaction times
- Reduced concentration
- Increased fatigue
- Higher risk of mistakes
For electrical workers operating around energized equipment, maintaining focus is critical. Cooling PPE helps workers stay alert and comfortable throughout the shift, supporting safer job performance.

The best heat stress prevention programs combine:
- Hydration
- Worker training
- Rest schedules
- Shade opportunities
- Proper PPE selection
