Safe Electrical Work Practices & The 2018 NFPA 70E
This video explains the important changes and updates contained in the 2018 NFPA 70E and explains how electrical workers can be protected from both the shock hazard and arc flash hazard presented by exposed energized parts. The 2018 NFPA 70E places an emphasis on controlling risk. As such the electrical safety program the shock hazard assessment and the arc flash hazard assessment must now consider the likelihood as well as the severity of injury related to an electrical hazard. When controlling risk the 2018 regulation now requires that a specific hierarchy of controls be followed.
Another new requirement is that the potential for human error be considered in all risk assessments. Annex Q has been added to help explain how human performance can be applied to workplace electrical safety. The required elements of the Electrical Safety Program have been revised to now include a written job safety plan in addition to a job briefing inspection of equipment incident investigation and risk assessment.
Other key changes include:
- Revised reference tables for establishing approach boundaries and selecting arc-rated clothing & PPE
- An additional unit of measure for incident energy selecting arc-rated PPE and establishing an arc flash boundary
- Updates of key definitions
- An explanation of employer and employee responsibilities
