Q: If there is no date on arc flash labels, how does the site electrician ensure the label is within the 5-year review period or other review requirements as defined in NFPA 70E? (…especially since Electricians don’t typically carry the latest arc flash drawings (or report) with them.) A: NFPA 70E – 2018 does not […]

Electrical Shock and Arc Flash Training: Simplifying the Process

Electrical Safety training can be difficult to implement. Complex rules from OSHA and NFPA 70E have to be incorporated into even more complex workplace roles and responsibilities (job descriptions). The aim of this short article is to simplify these requirements in an easy-to-digest manner. This is aimed at persons new to electrical safety. OSHA should […]

IEEE 1584-2018 Has Replaced the 125kVA Exception: What Are the Implications for You?

New IEEE 1584™ -2018 wording: “Possible but less likely” The IEEE standard 1584™ – 2002 Guide for Performing Arc-Flash Hazard Calculations stated, “Equipment below 240 V need not be considered unless it involves at least one 125 kVA or larger low impedance transformer in its immediate power supply.” The recently published IEEE standard 1584™ – […]

Is there an OSHA standard that mandates extension cords cannot be plugged into each other? We had a client once comment: “I have been reading about plugging extension cords. I want to make sure when I go on one of our sites and say, ‘You can’t plug one cord into another’ that I can give […]

What We’ve Learned about Arc Flash in Data Centers

As more data centers emerge around the country, we are presented with more opportunities to learn lessons about arc flash. “An energy-intensive data center requires multiple high capacity sources to function. When there is a failure, the arc flash energies are also notably greater when compared to small industrial  networks.” So begins a recently published article […]
