Arc Flash Electrical Safety NFPA Z462® On-Site Training

This on-site training class is also available as Public Schedule Seminar.

This training course is designed to save lives, prevent disabling injuries, and prevent damage to plants, building and equipment.

Course Description/Agenda

The Electrical Safety and Z462 Arc Flash Protection training course is designed to save lives, prevent disabling injuries, and prevent damage to plants, building and equipment.

Based on NFPA Z462, students attending this course will gain an immense respect for the power of electricity. They will learn about personal safety for working on or around electrical systems and equipment, how to use proper materials and procedures for doing electrical work - and the potential consequences for themselves or others if they don't.

Taught as if they were our own employees, students are given practical instruction that they can immediately apply when they go back to their workplace. This course also helps companies' meet their OSHA training obligations as outlined in CFR 1910.331-335.

Whether your employees are machine operators, maintenance personnel or experienced electricians, this course is an absolute "must" for anyone working on or around electrically energized systems and equipment.

Who should take this course?

This seminar is a must for anyone who works on or around any electrically energized equipment at industrial plants, utilities or commercial and private building facilities. From machine operators and janitorial personnel, to maintenance workers and experienced electricians - anyone who comes in contact with electrical equipment must receive Electrical Safety training to be in compliance with the requirements of OSHA standard CFR 1910.331-.335.

What You Will Take Home

Take-home materials include

  • A laminated, full-color ATMT? Reference Guide detailing all the ?must-know? information covered in the class. Keep this with you while on the job for immediate knowledge recall.
  • A comprehensive Study Guide for additional reference and preparation for optional ATMT? Testing and Certification
  • A Personalized Training Certificate with 0.8 American Trainco Continuing Education Units for each day attended, 1.6 for both days, and
  • All the information you need from asking our instructors specific questions about your own unique equipment or facility.

Common Questions about Arc Flash

Q: What happens in an arc flash or arc blast?
A: Arc flashes cause electrical equipment to explode, resulting in an arc-plasma fireball. Temperatures may exceed 35,000? F (the surface of the sun is 9000? F). These high temperatures cause rapid heating of surrounding air and extreme pressures, resulting in an arc blast. The arc blast will likely vaporize all solid copper conductors; solid copper expands to 67,000 times its original volume when it is vaporized. In addition, measurements taken on a test mannequin during a laboratory arc flash detected sound levels of 141.5 decibels at two (2) feet from the blast, and pressure levels of 2,160 pounds per square foot (psf) in the immediate vicinity of the arc blast.

Q: What is NFPA 70 E?
A: NFPA 70 E is intended to provide guidance with respect to electrical safe work practices.

Q: What is the difference between NFPA 70 (NEC?) and NFPA Z462?
A: The National Electrical Code? is generally considered an electrical installation document and protects employees under normal circumstances. NFPA Z462 is intended to provide guidance with respect to electrical safe work practices

Q: What standards regulate electrical safety and arc flash hazards?
A: There are four main regulations that govern electrical safety and arc flash.

1. OSHA Standards 29-CFR, Part 1910. Occupational Safety and Health Standar
