NFPA 70E (2009) - Module 3: Energized Electrical Work Permits
This self-paced online training course covers the sections of the NFPA 70E standard that provide workers with safety guidelines for times when de-energizing is not possible or when it could create increased or additional hazards. The requirements for energized electrical work permits were a new addition to the 2004 edition of NFPA 70E and were reorganized and clarified in 2009. This course will focus on exploring the different elements of these permits and why each is important.
Upon completion you should be able to:
- Formulate the justification for working on energized circuits.
- Define the approach boundaries surrounding energized circuits.
- Identify the flash hazard analysis procedure and the flash protection boundary.
- List the methods of limiting exposure to unsafe work conditions by unqualified persons.
Who Will Benefit
Anyone whose job involves designing, reviewing, evaluating or installing fire protection systems, including: designers, installers, engineers, electrical contractors, technicians, project managers, fire marshals, and architects.
Minimum Computer System Requirements
- In most cases, energized electrical work (work involving electrical hazards) requires the completion and approval of an energized electrical work permit.
- After identifying the circuits and equipment to be worked on, a written justification for the work must be provided, and the safe work practices that will be employed must be identified.
- A shock hazard analysis will determine:
- Who will be exposed to what voltage
- Locations of the three Approach Boundaries.
- Necessary PPE to minimize or eliminate the threat of electric shock (typically voltage-rated insulation of some type)
- A flash hazard analysis will determine:
- The risk of an arcing fault
- The Flash Protection Boundary (where flash protection PPE is required)
- Necessary PPE to minimize or eliminate the threat of arc flash burns (the rating of PPE required)
- Other important elements of an energized electric work permit include:
- The necessary PPE to safely perform the assigned task
- Means employed to restrict the access of unqualified persons from the work area
- Evidence of completion of a job briefing
- Energized work approval signature(s)
