Arc Flash

Arc flash harnesses are specialized safety equipment designed to protect workers from the hazards associated with arc flash incidents, which occur when an electric arc releases a burst of energy, including intense heat, light, and pressure waves. Here's a quick overview of why arc flash harnesses are different from standard harnesses:

  1. Flame Resistance: Arc flash harnesses are made from materials that are highly flame-resistant to protect workers from burns and injuries in the event of an arc flash incident. These materials, such as Nomex or Kevlar, are designed to self-extinguish and prevent the spread of flames, reducing the severity of injuries.

  2. Arc Flash Protection: The primary purpose of arc flash harnesses is to provide protection against the thermal and radiant energy produced during an arc flash event. They are constructed with layers of flame-resistant fabric and insulation to shield the wearer from the intense heat and light generated by the arc flash.

  3. Electrical Insulation: Arc flash harnesses may feature additional layers of electrical insulation to protect workers from electric shock in the event of contact with live electrical conductors. These insulation layers help to prevent electrical current from passing through the harness and into the wearer's body, reducing the risk of electrocution.

  4. High Visibility: Many arc flash harnesses are designed with high-visibility colors or reflective tape to increase visibility in low-light conditions or in environments with heavy machinery or traffic. This helps to enhance worker safety by making them more visible to coworkers and equipment operators.

  5. Specialized Components: Arc flash harnesses may include specialized components such as non-conductive hardware, flame-resistant stitching, and reinforced webbing to ensure durability and reliability in harsh working environments. These components are designed to withstand the rigors of daily use and provide long-lasting protection for workers.

  6. Certification and Compliance: Arc flash harnesses are often certified to meet specific industry standards and regulations, such as ASTM F887 for arc flash protection and NFPA 70E for electrical safety in the workplace. Compliance with these standards ensures that arc flash harnesses provide the necessary level of protection for workers exposed to arc flash hazards.

In summary, arc flash harnesses are specialized safety equipment designed to protect workers from the hazards associated with arc flash incidents. With their flame resistance, arc flash protection, electrical insulation, high visibility, specialized components, and certification compliance, these harnesses are essential for ensuring the safety of workers in environments where arc flash hazards are present

Colorado safety company is a great company to do business with. Knowledgeable staff. Super friendly. They are always going above and beyond! If you need any industrial/construction safety items do yourself a favor and reach out to Val and her crew! Such a solid group of people.

I took an OSHA 30 class with Matthew Creasey. Safety stuff can be really boring and arduous, but Matthew kept the class surprisingly lively and entertaining. He is obviously skilled and experienced in safety and presented relevant material in each section of the class. He kept all the participants engaged throughout the whole course. Matthew and the rest of the Colorado Safety Supply staff were very welcoming and even provided delicious home cooked snacks on one of the days for the whole class. I learned a ton and would absolutely revisit Colorado Safety Supply Company for any future trainings. I highly recommend!
