This is probably one of the best ways to prevent an arc flash. Make sure all of your workers that are working on energized electrical systems are qualified to do so. OSHA requires this training too. Lack of training is often cited as a reason for fines from OSHA. When you do this training make sure to document it thoroughly.

2. Perform an Arc Flash Study


An arc flash study can help to determine the incident energy level at all working locations. This will also help to determine the levels of personal protective equipment (PPE) needed

3. Wear Appropriate PPE


Wearing the proper clothing is key to protecting yourself it an arc flash would happen.
Some of the different types of PPE that you should consider wearing are listed below:
• Flame-resistant clothing
• Helmet or headgear
• Face shield
• Safety glasses
• Insulating gloves
• Shoes appropriate for electrical work (that contain no metal)

4. Mark Your Equipment


Make sure to mark your equipment to warn of hazards. This is a revision to NFPA 70 that took place in 2002. This will help your workers to be aware of where the hazards exist.
