NFPA 70E Arc Flash Electrical Safety with Hands-On Practical Skills Training

Go beyond the theory & knowledge training you're used to. Advance to hands-on practical skills and application safety training. This seminar is designed to save lives, and indeed it has. This is NTT Training's foundation seminar for electrical qualification updated to the 2015 NFPA 70E.

This training instructs participants on the electrical safety skills needed to perform routine electrical maintenance tasks at less than 1000 volts just as they would in the field.

Student are encouraged to bring their own PPE to use in the hands-on labs:

• Meter
• Gloves
• Tools
• Arc-rated Clothing (PPE Categories 2 and 4)

What You Will Learn

Topics covered during this training include:

Understanding the NFPA 70E, and the changes in the 2015 edition (This is designed for a qualified person)

• Apply OSHA rule 1910.331-335 training requirements and NFPA 70E standards
• Understand the effect of maintenance on equipment and how it reduces injury
• Test instruments making contact with energized parts
• Perform safe electrical work practices and understand arc flash hazards and boundaries
• Updated tables and Approach Boundaries: Understand the impact of the 2015 change -- "hazard analysis" has been replaced with "risk assessment"
• Construction and maintenance work has been separated from outdoor work
• New requirement 320.3 (A)(1) covers risk assessment associated with battery work

Practical Application discussion and hands-on lab activities include:

• Simple / Mechanical LOTOTO , (NO Verify absence of voltage)
• 120/208 Volt disconnect. Electrical LOTOTO , Verify absence of voltage
• Check amps (a meter task)
• Check volts (a meter task)
• Change fuses
• MCC Troubleshoot
• Using electrical diagrams
• Selecting and using voltmeters (electrical test equipment and special tools)

This provides an opportunity for participants to verify the ratings and conditions of the PPE they use in the field under the instructor's guidance.

Activity Description

Students will use the appropriate procedure checklist to perform each task. When student is not performing a task, they will use the appropriate checklist to audit the task performance of other personnel as assigned by the instructor. Students are to complete all assigned written exercises.

Training Topics Include

• Discussion of OSHA and 70E requirements for demonstration of skills.
• Overview of MCC Trainer, associated equipment and PPE.

Hands-On Lab Procedure
