Arc protection PPE (Personal Protective Equipment) is designed to protect workers from the thermal hazards of an arc flash. An arc flash is a dangerous release of energy caused by an electrical fault. Here’s an overview of arc protection PPE and instructions for use:
Types of Arc Protection PPE
- Arc-Rated Clothing:
- Shirts and Pants: Made of flame-resistant fabrics with arc ratings. These should cover the entire body.
- Coveralls: Full-body suits that provide additional protection.
- Jackets: For additional layering and protection in colder environments.
- Arc Flash Face Shields and Hoods:
- Face Shields: Provide protection for the face and neck. Should be used with an appropriate helmet.
- Hoods: Offer full head and neck protection, typically used with a face shield for enhanced safety.
- Gloves:
- Arc-Rated Gloves: Protect hands from thermal burns. Should also provide electrical insulation.
- Safety Glasses:
- Arc-Rated Safety Glasses: Protect the eyes from intense light and potential flying debris during an arc flash.
- Hearing Protection:
- Ear Plugs or Muffs: Protect hearing from the loud noise generated by an arc flash.
- Boots:
- Arc-Rated Boots: Made of materials that won’t ignite or melt when exposed to an arc flash.
Selecting Arc Protection PPE
- Arc Rating (AR) or Arc Thermal Performance Value (ATPV):
- The arc rating indicates the level of protection provided by the fabric. Choose PPE with an arc rating suitable for the energy level of potential arc flash hazards in your work environment.
- Fit and Comfort:
- Ensure the PPE fits well and is comfortable to wear. Loose or poorly fitting PPE can compromise safety.
- Layering:
- Layering can provide additional protection. Ensure that all layers are arc-rated.
- Compliance:
- Ensure the PPE meets relevant standards such as NFPA 70E, ASTM F1506, or IEC 61482.
Instructions for Use
- Pre-Use Inspection:
- Inspect all PPE for any signs of damage or wear. Do not use damaged PPE.
- Donning (Putting On) PPE:
- Follow the manufacturer’s instructions for donning PPE. Ensure all clothing is fastened securely.
- Wear a base layer of arc-rated clothing if required.
- Ensure all parts of the body are covered, including the neck, wrists, and ankles.
- While Working:
- Follow safe work practices as outlined in NFPA 70E or your organization’s safety protocols.
- Maintain a safe distance from potential arc flash sources.
- Use insulated tools and equipment rated for the voltage levels you will be working with.
- Doffing (Taking Off) PPE:
- Remove PPE carefully to avoid contamination.
- Follow proper procedures for cleaning and storing PPE.
- Maintenance and Care:
- Regularly clean and inspect PPE according to the manufacturer’s instructions.
- Store PPE in a clean, dry place away from direct sunlight and chemicals.
Additional Resources
- Training: Ensure all workers receive proper training on the use and maintenance of arc protection PPE.
- Risk Assessment: Conduct regular risk assessments to determine the appropriate level of PPE needed for specific tasks.
- Emergency Procedures: Have clear procedures in place for dealing with arc flash incidents, including first aid and medical response.
Proper use and maintenance of arc protection PPE are critical for ensuring safety in environments where arc flash hazards are present.
