NFPA 70E 2018

NFPA has just released the 2018 edition of the NFPA 70E “Standard for Electrical Safety in the Workplace”. At ASG Electric, we strive to be a key resource in assisting our clients to develop a strong “70E/OSHA Compliant” electrical safety program.

Looking back, 70E – 2009 was the first edition that called for the electrical safety program to assess and “label” each component with the available incident energy result or a category of PPE to be worn for energized work. The central focus was to define the hazard/injury potential at each “serviceable point” within the electrical system.

70E – 2012 had many points of emphasis on improved documentation. These included:

  • condition of maintenance – tests and inspections shall be documented (205.4)
  • there shall be a documented meeting between a host employer and contractor to review the policies and practices of the electrical safety program (110.1)
  • the content of the training program shall be included in training documentation (110.2)

70E – 2015 focused extensively on “condition of maintenance”. The very scope of 70E was revised (see Scope 90.2) to include an emphasis of “safety related maintenance” as a core element of the electrical safety plan. This was a welcomed enhancement to the 70E standard to fully recognize that the source/triggers of an arc flash incident is within the electrical components and not the label posted on the cover. Gathering only device nameplate data (to create labels) was no longer sufficient and an electrical testing and inspection program should also be part of your “70E compliant” electrical safety program.

For 70E-2018, one of key points of emphasis is found in 105.3. “The employer shall have the responsibility to establish, document and implement the safety related work practices and procedures required by this standard. This new article brings with it the challenge of understanding the arc flash risk potential in the electrical system and assessing the existing work practices current in place regarding energized electrical work. The 2018 standard also specifically defines that hazard elimination shall be the first priority in the implementation of safety-related work practices. In summary, 70E-2018, creates a call to action to not only document the “as found” electrical system, conduct employee training and provide PPE, but to evolve to “what should we be doing to better protect our employees?”

Many updates in the 70E-2018 have a significant focus on the employee/worker. 70E-2018 calls for a risk assessment procedure, and the long-standing hierarchy of risk control methods has been elevated as an article within the 70E standard. A job safety planning process has been defined more deeply and a job briefing is also required for energized work. In continuing the focus on the worker, 70E-2018 calls for a safety program that includes elements that will trigger “incident investigations” when close calls or near mi

sses take place.

 

While the three key components of making known the hazards, provide training, and providing PPE are still solidly in place, 70E-2018 brings a focus on the “people aspects” as organizations establish, document, and implement their electrical safety program.

Heat Tape – protecting your roof

Ice dam problem

Are ice dams creating issues for your roof? Have the ice dams created “ice ponds” on your walkways? Has additional insulation and air sealing not helped to solve the problem? ASG can install heat tape! When installed correctly, heat tape can provide a path for ice and snow to melt off of the roof. It can also keep gutters and down spouts from becoming clogged with ice.

A quality installation is a key performance metric of your heat tape system. It is important to create a proper heat tape design/material plan for your installation. The recommendations of the heat tape manufacturer’s regarding how the heat tape is to be installed should influence the installation/design. The design process eliminates the potential for a poor and underperforming system.

Other installation activities include heat tape system documentation, panel and breaker load assessments and full testing of the system.
