Flame-resistant (FR) clothing, including FR hoods, plays a crucial role in protecting workers in industries like electrical, oil and gas, and welding from fire hazards. Among the protective gear, FR hoods are designed to shield the head, neck, and sometimes shoulders from flash fires, arc flashes, and radiant heat. While these garments are engineered to provide maximum protection, improper use can significantly reduce their effectiveness. Understanding common mistakes and learning how to avoid them is essential for workplace safety.
Choosing the Wrong Type of FR Hood
One of the most common mistakes is using an FR hood that isn’t suitable for the specific hazard. FR hoods are not “one size fits all” for different work environments. Some hoods are rated for arc flashprotection, while others are designed for flash fire resistance. Using the wrong type can leave you exposed to serious injury.
How to Avoid It:
- Check the hazard classification of your work environment. The NFPA 70E standard for electrical safety and NFPA 2112 for flash fire protection provide detailed guidance.
- Ensure the hood’s arc rating (cal/cm²) or flash fire rating (seconds of protection) meets or exceeds the required level.
- Verify that the hood is tested and certified by recognized safety organizations.
Ignoring Proper Fit
A poorly fitted FR hood can compromise protection. If the hood is too loose, flames or heat can reach exposed areas. If too tight, it may be uncomfortable, causing workers to remove or adjust it frequently, which increases exposure risk.
How to Avoid It:
- Follow sizing charts provided by manufacturers. Measure your head and neck accurately before purchasing.
- Ensure the hood fits snugly around the face, neck, and shoulders without restricting movement.
- Try the hood on with other PPE like helmets or safety glasses to ensure compatibility.
Wearing the Hood Over Non-FR Clothing
Another mistake is wearing the FR hood over regular clothing. In an emergency, non-FR fabrics can catch fire and burn intensely, putting the user at greater risk. Even small gaps can allow heat or flames to reach skin.
How to Avoid It:
- Always wear FR-rated base layers under the hood.
- Avoid synthetic fabrics like polyester or nylon, which can melt.
- Layering should be minimal and composed of FR-certified garments to maintain protective coverage.
Neglecting Maintenance and Cleaning
FR hoods require proper maintenance. Dirty, oily, or worn hoods can reduce flame resistance and overall protection. Oils, chemicals, and dirt can create hotspots during an arc flash, while worn fibers reduce thermal protection.
How to Avoid It:
- Follow the manufacturer’s washing instructions strictly—typically, mild detergent and cold water. Avoid bleach or fabric softeners.
- Inspect the hood before each use for tears, frays, or burn marks.
- Replace hoods that show signs of wear or repeated contamination with chemicals or oils.
Incompatible Use with Other PPE
Using an FR hood with other PPE incorrectly can compromise protection. For example, wearing a hard hat that pushes the hood away from the neck or improperly combining face shields can expose vulnerable areas.
How to Avoid It:
- Ensure all PPE fits together seamlessly.
- Conduct a PPE compatibility check—move your head, lift arms, and simulate tasks while wearing full gear.
- Choose FR hoods that are designed to be worn with helmets, safety glasses, and face shields if required.
Not Securing the Hood Properly
Leaving the hood loose or improperly fastened is a frequent mistake. During work, loose hoods can shift, exposing skin to flames or hot metal. Even momentary exposure can cause serious injuries.
How to Avoid It:
- Use hoods with adjustable straps or elastic closures to ensure a tight fit around the neck and shoulders.
- Tuck the hood properly into other clothing layers to prevent gaps.
- Train workers on the importance of securing their hoods correctly before entering hazardous zones.
Misunderstanding Reuse Limitations
Some workers believe FR hoods are reusable indefinitely. However, repeated exposure to heat, chemicals, and washing cycles reduces the hood’s protective qualities over time.
How to Avoid It:
- Follow manufacturer guidelines for the service life of the hood.
- Keep a log of usage and exposure for each hood.
- Replace hoods that have exceeded their recommended lifespan or show signs of degradation.
Improper Storage
Storing FR hoods improperly—near heat sources, chemicals, or in damp conditions—can weaken fibers and reduce flame resistance. Many workers simply toss their hoods into lockers, risking damage.
How to Avoid It:
- Store hoods in a cool, dry place away from direct sunlight and chemicals.
- Use dedicated PPE storage areas or hanging racks to prevent crushing or wrinkling.
- Keep hoods clean and dry before storage.
Failing to Train Workers
Even the best FR hoods fail if workers don’t know how to use them correctly. Lack of training can lead to mistakes in fit, maintenance, and compatibility with other PPE.
How to Avoid It:
- Provide regular safety training focused on the correct use, care, and limitations of FR hoods.
- Conduct hands-on demonstrations on proper donning and doffing techniques.
- Include FR hood safety in routine safety audits and hazard assessments.
Ignoring Environmental Hazards
Certain environments, such as areas with chemical exposure or extreme cold, can affect the performance of FR hoods. Chemicals can degrade flame-resistant fibers, while moisture or frost can reduce insulation.
How to Avoid It:
- Assess the work environment for additional hazards beyond fire.
- Choose FR hoods made for multi-hazard conditions if needed.
- Perform regular inspections and replace hoods that show environmental damage.
FR hoods are essential for protecting workers from fire and thermal hazards, but their effectiveness depends on correct usage, fit, and maintenance. Common mistakes—such as choosing the wrong hood, wearing it improperly, or neglecting maintenance—can reduce protection and increase risk. By understanding these mistakes and taking proactive steps to avoid them, employers and workers can ensure that FR hoods provide the intended level of safety.
Proper selection, fit, maintenance, training, and storage of FR hoods, combined with full compliance with safety standards like NFPA 70E and NFPA 2112, create a safer working environment. Remember, FR hoods are a critical piece of the PPE puzzle, and their correct use can be the difference between minor exposure and serious injury. Safety is always a combination of the right equipment, correct practices, and vigilant awareness.
