Anyone who works with electricity knows how important it is to be aware of potential safety hazards. These hazards include shock, arc flash heat and explosions that can take place due to electrical mishaps. Predicting the level of hazard can be calculated thanks to the NFPA 70e Standard for Electrical Safety in the Workplace.

The NFPA 70e was officially adopted by OSHA and is now a standard that employers and employees must abide by, in addition to ensuing all electrical equipment complies. This compliance is required on any equipment emitting over 50 volts and can effect solar DC systems and UPS batteries.

Electrical safety standards are constantly improving and the NFPA 70e committee updates their standards every few years. David Weszely of Lewellyn Technology highlights changes to the standards for the upcoming year in his article: The Most Important 2018 Changes in NFPA 70e.

Here’s a synopsis of his review:

  • A qualified person will need to complete a Job Safety Analysis (JSA) before work or troubleshooting is performed.
  • Adding a personal protective equipment (PPE) conformity assessment to promote consistency.
  • Arc flash and shock hazard risk assessment now include the “potential of human error.”

Weszely suggests that companies make sure all qualified workers have access to the 2018 NFPA 70e standard, update their electrical safety program and schedule on-site NFPA 70E electrical safety training.
