Arc Flash Assessment

A Lewis Bass Arc Flash Assessment can help your company determine if the potential for a hazardous electrical arc flash exists in equipment that your employees work on or near and may also be a requirement of maintaining insurance coverage at your facility.

What Is An Arc Flash Assessment?

An ArcFlash Hazard Assessment determines the degree to which a worker may be exposed to potential ArcFlash Hazards and what kind of Personal Protective Equipment (PPE) is required to protect workers from the heat, light, and blast associated with an ArcFlash accident.

As required by OSHA and the NFPA 70E, Lewis Bass’s Arc Flash Assessment service helps determine if the potential for a hazardous electrical arc flash exists in equipment that employees work on or near while the equipment is exposed and energized.

Why Choose Our Arc Flash Assessment Service?

Arc Flash Assessments Are An Investment In Your Business
