Arc flash hazards are governed by NFPA 70E guidelines and OSHA. Due to the extreme potential dangers of an arc flash situation, there is no leeway given by OSHA or NFPA as it relates to this threat. Correct signage, identification, and borders must be established and regular audits must be performed or your workplace will be unsafe and subject to significant fines.
Many companies only test equipment at 240 V and higher, due to the information released in IEEE 1584. Unfortunately, that only relates to incident energy calculations and does not exempt any companies from the NFPA and OSHA regulations requiring testing of all equipment 50 volts or higher. Testing must also be done on all equipment, regardless of whether it is supplied by a Hazard Risk Category 0 panel. The incorrect assumption that a Hazard Risk Category 0 feed is safe from arc flash hazards has cost many companies substantial sums in penalties from OSHA, and created woefully unsafe environments for employees.
Testing for arc flash hazards can be confusing and unsettling, even for the most experienced safety managers. And with the fluidity of most modern companies, it can be difficult to stay on top of regulatory adherence. But don’t worry, we are here to help. We will test all of your equipment, ensure you are up to code according to NFPA 70E, and create custom signage to make sure you have a safe work environment for your employees.
