Hazard Control Measures

Though arc flash events present a very serious threat to those involved in them, there are tested measures that can be taken to reduce this threat. Arc flash hazard control measures can reduce the possibility for an arc flash to occur in equipment while workers are in the vicinity, and may reduce the amount of harm the worker will receive in the event of an arc flash.

The measures described are required safety regulations that align with NFPA 70E and OSHA 29 Code of Federal Regulations Part 1910 Subpart S. Controls available at the point of designing equipment are provided, as well as controls that can be implemented in the workplace at the administrative and procedural levels.

The National Institute for Occupational Safety and Health (NIOSH) organizes the process of controlling hazards into a three-stage safety model. This model can be used to shape efforts for reducing the hazards posed by arc flashes in the workplace.

NIOSH Safety Model:

1. Recognize hazards
2. Evaluate hazards
3. Control hazards
