Electrical Safety Updates
The National Fire Protection Association has made several updates to NFPA 70E, including some of the first arc flash protection requirements for electric power generation.
The primary responsibility of the Occupational Safety and Health Administration (OSHA) is to make the work place safer for employees. The new requirement with OSHA 1910.269 provides guidance on proper tools to use and directions to follow when estimating available heat energy. It references National Electrical Code (NEC) article 110.16 which says that everything in the work place should be labeled. The new updates define which types of equipment need to be labeled, like switchgear, switchboards and enclosures.
It is not enough to see a “DANGER - HIGH VOLTAGE,” sign and think that is enough information for the worker to know the appropriate tools to use or the proper protection equipment (PPE) to wear. The changes to NFPA 70E-2015 make it clear the information that needs to be included on the labels. Specifically, it states the label should include:
- Nominal system voltage
- Arc Flash boundary
And at least one of the following:
- Incident energy & working distance
- PPE category from NFPA 70E
- Minimum PPE arc rating
- Site specific level of PPE
Also, the NFPA 70E arc flash tables are easier to read than before, making it more clear which clothing protection to choose for the task. Read the latest version of NFPA 70E for more detail or contact our dealership.
