Dear ArcLetter Member,


The ArcWear™ Electric Arc and Safety Newsletter provides a quick update on Arc Rated and Flame Resistant Clothing issues and news from OSHA and standards committees. The newsletter is FREE, reaches over 14,000 people and will bring you up to date on the issues that surround flame resistant clothing for flash fire hazards and the electric arc.

April Survey Results:  PPE system greater than 1.2 to 12 cal/cm²

2012 NFPA 70E Annex H.3 was changed to allow a 
cal/cm² to 12 cal/cm² PPE system.  

Has your company implemented this approach?


Comments from Survey-Takers:

1. My company has a two-category arc flash PPE approach. Daily wear 8 cal/cm2 (HRC's 2 and below) and 40 cal/cm2 (HRC's 3 and 4).

2. This just confuses the issue of what PPE is required.

3. Even if our labeling has been done following arc flash studies, we had already implemented the approach based on defined hazard/risk categories since 2009 and impacts would have been too large with not enough value added.

4. We are currently deciding further action on this and how we will further implement it.

5. We calculate IE levels at each piece of equipment. The normally worn AR clothing is rated 8.6 (shirt) and 12.6 (pants). When the IE level is >8 a sweatshirt (AR rating 17) is worn over the shirt. A 12 cal faceshield is worn with an optional balaclava. This covers ~95% of the equipment on site. For higher exposures we use special procedures and higher rated AR suits.

6. It could change in the future, but for now we are keeping the minimum 8 cal clothing for every day use and continuing up to 40 cal for task oriented work as governed by the arc label on the equipment as per analysis.

 Q&A:  DANGER:  Over 40 cal/cm² Exposure


Q.   We just had our Arc Flash Analysis completed and we now have some Arc Flash labels that say "DANGER - > 40 cal/cm² exposure; no PPE found". We have 65 cal/cm² arc flash suits; can we use those?  Chuck


A.  A very good question; I'll do my best to answer it. The 40 cal/cm² cut off point is a misinterpretation of a statement in NFPA 70E.  The statement intends to warn that IF your hazard is greater than 40 cal you should consider arc blast in your hazard assessment.  The statement does not require DANGER in the label and doesn't require PPE to be no greater than 40 CAL but some arc calculation software mistakenly interpreted this that way.  The evidence does not support this approach. 


Arc Blast has no correlation to incident energy (cal/cm²). Incident energy is a function of several parameters including time of the exposure, fault current area configuration (box size, location and room size/shape) and worker distance from the arc.  Only two of these is related to blast pressure: fault current.  If NFPA 70E had evidence more than an anecdotal door blown off here and there, they would have required a certain fault current or location type for no work to occur but the means to predict arc blast is not yet is place. This is one of the reasons IEEE 1584 is considering charging for the software in a way to protect the intellectual property.  The steering committeee wants to do more arc flash research.  But there is NOT a requirement to NOT do work do any work over 40 cal/cm² is nor is there any requirement that there NOT be any PPE >40 cal/cm². The current standards have a practical cut off at about 100 cal/cm² though some have found non standard means to test >100.  Fault current is the only practical cutoff and that has not been set.


Annex F in NFPA 70E is a risk evaluation matrix to provide you with information on how to perform tasks that are of a higher risk, above the 40 cal/cm² value, to establish a safe work zone.


For instance, the task might be replacing a branch circuit breaker in the switchgear in question.  You can use annex F to determine your risk for the specific task of opening the main breaker to create a safe work zone to replace the branch breaker. The risk would be too high to replace the branch circuit breaker in an energized state and would require an energized work permit also.


Over the years we have heard many stories about the blast effect above 40 cal/cm². We know there is a blast effect, just how large it is and how it affects the human body we don't know. More research will need to be completed to fully understand and determine a safe level of blast.


Years ago I worked with a Motor Control Center manufacturer developing an arc resistant MCC. We found the smallest MCC bucket had the largest destructive blast effect, yet the cal/cm² was the same throughout the MCC.


Utilize Annex F to determine your risk for the specific task above the 40 cal/cm² exposure to create a safe work zone.  Look at your data in the study to determine exactly what is the cal/cm2 of exposure. You might find the exposure is 44 cal/cm2 and the software defaulted to DANGER for any task above 40 cal/cm2. You may find the risk is simply too high to operate the main disconnect and you'll need to perform the task another way, for instance, open all the branch breakers to reduce the load on the transformer, then open the High Voltage primary switch where the exposure is less.


In my personal opinion, if answer from Annex F indicates a very high probability, FIND ANOTHER WAY to de-energize the equipment.

Orex Arc Rated Coverall


For application where nuclear particulates could be an issue the OREX CS5000 coverall that is arc-rated at 9.2 cal/cm2 and meets ASTM F1506 and can be dissolved in a solvent to remove the contamination.  This allows nuclear plants to safely dispose of the garments without incineration.

7 Electrical Safety Habits
Interesting Fact....

An electrical engineer invented the zipper. He moved from Sweden to Canada and worked for Westinghouse. In 2012 the electrical safety standard NFPA 70E now requires zippers to be flame resistant and non-melting at 500 degrees F for 30 minute in an oven. Most of these zippers will now be used in arc flash clothing which is arc rated.
