What are the NFPA 70E requirements for arc flash protection?

The NFPA 70E standard provides guidelines for electrical safety in the workplace, including requirements for arc flash protection. Some of the key requirements include:

1. Employers must perform an arc flash hazard analysis to determine the level of risk and establish safe work practices and PPE requirements.

2. Employees who work on or near energized equipment must be trained on the hazards of arc flash and the proper use of PPE.

3. PPE must be selected based on the level of arc flash hazard and must meet certain performance standards.

4. Employers must establish an electrical safety program that includes procedures for working on or near energized equipment.

5. Employers must ensure that equipment is properly maintained and inspected to prevent arc flash hazards.

6. Work on or near energized equipment should be avoided whenever possible, and de-energized equipment should be locked out and tagged out before work begins.

7. Employers must establish safe work zones and provide warning signs and barriers to prevent unauthorized access.

These requirements are designed to protect workers from the hazards of arc flash and ensure that they are properly trained and equipped to work safely around energized equipment.
