70e Training - Electrical Safety in the Workplace

70e Training Course

Our 70e Training course is designed for front-line workers who are responsible for electrical systems and needing certification in the NFPA arc flash/electrical safety standard.

This NFPA 70e Training course teaches safe work practices related to electrical dangers in the workplace. The successful participant will gain a solid understanding of hazards encountered while operating or maintaining electrical installations in the low voltage (below 750V) class including a full understanding of the arc hazard categorization, appropriate PPE selection and safe work procedure.

This arc flash safety course is designed to assist organizations to identify shock and arc flash hazards and prevent injuries and incidents associated with those hazards.

THIS COURSE WILL TEACH YOU HOW TO

  • Identify electrical safety training requirements for qualified workers
  • Identify best practice Regulations that address shock and arc flash hazards
  • List the steps to perform a shock hazard analysis and describe each step
  • Define the three NFPA-70e shock protection boundaries and describe their use
  • List the personal protective equipment required for shock protection
  • List the steps to achieve an electrically safe work condition
  • List the steps to install and remove temporary protective grounding equipment
  • Explain what an arc flash is and the injuries that can result
  • Identify when an arc flash hazard exists
  • List the steps to perform an arc flash hazard analysis and describe each step
  • Define the term “incident energy,” identify the key electrical system variables that affect it
  • Define the term “arc flash protection boundary” and explain its application
  • Define the term “arc-rated” and explain the difference between “flame-resistant” clothing and “arc rated” clothing
  • Select appropriate personal protective equipment for arc flash hazards
  • Describe the Hazard/Risk Category method of selecting arc flash PPE
  • List the testing and maintenance requirements for personal protective equipment
  • Identify the key objectives of job safety planning
