photo-materialsFall is a great time to get things on the schedule that you didn’t get to over the summer. Maybe a refresher course or a new training video? Our 7 Electrical Safety Habits and NFPA 70E Training videos are now available for 2012 NFPA 70E.

Check out our upcoming classes and sign up today. Also, it’s always a good idea to stay current on the most recent standard updates. Take a look at our article on the changes to the glove standard as well as our video on anti-fog face shields.

There is no time like the present to get caught up! Let us know how we can help.

Burn Up The Myth: Q&A with e-Hazard/ArcWear

Burning Question

Q:  I have a question related to ASTM F2178.  I heard some complaints from electricians that 8 cal face shields are amber-tinted and much easier to see through than 40 cal hoods.  Their argument is that the UV is the same regardless of energy and the 40 cal lens should be as easy to see through as the 8.  I am not familiar with, nor do I have access to F2178, but do you have any thoughts on why the higher calorie lens would be darker and more difficult to see through?


A: The UV blockers are not what make the shield darker, and UV is not what burns you the most in an arc flash. The blocking of infrared (IR) and visible light is what creates the darkening. The arc visible light, which is intense and can cause burns, consists of very little UV but mainly IR and visible light. This is why more blocking of these types of light necessitates a darker shield. The same is true in welding: Cutting torch lenses are pretty dark, but welding lenses are almost black because more blocking is needed.  We worked with all the manufacturers to tweak these shields over the years to block enough to prevent second-degree burn but still allow visibility.


ASTM F2178 doesn’t speak about how or what to block-it just relates to testing in a real arc flash situation.  Newer shields have gotten clearer and clearer, but some of the hood manufacturers have not kept up with the latest shield advancements and so use old technology.  Try several brands-you will be surprised by the differences.  The largest face shield manufacturer, Paulson, has about three generations of shields that it manufactures to accommodate the companies which don’t want to retest or move to a newer shield technology.  Do a wear trial.  It makes a difference.  And don’t forget to get a fan in hoods-that makes workers a lot happier too!

Anti-Fog Face Shield Testing

Hugh Hoagland and his team from e-Hazard went to Louisville Processing and Cold Storage to conduct a series of experiments on anti-fogging technologies in face shields. The experiments were conducted in the facility’s Cold Room, a controlled environment of -13 degrees F (-25 C). The experiments were a simulation of workers using Personal Protective Equipment for arc flash protection in an extreme cold work environment.

Gloves, Arc Flash, and the New ASTM Test Method

Logo: OHS Read Hugh Hoagland’s article  on the  New ASTM Glove Test Method from the August issue ofOccupational Health & Safety.




For years, we have heard the question, “What about gloves in arc flash?” The reason this question wasn’t answered sooner is complicated, but the standard is now available. ASTM F2675-13, Test Method For Determining Arc Ratings of Hand Protective Products Developed and Used for Electrical Arc Flash Protection, is an ASTM International standard with an approval date of June 1, 2013, that was expected to be published by ASTM International within the month of July. Testing is already progressing, with more than 25 types of gloves tested in the past few years now having a specific standard to target.

The question often arises as to whether an Arc Thermal Performance Value (ATPV) or an photo-arc-explossion-2 Energy Breakopen Threshold (EBT) is better protection in a garment system. When  ASTM F1959 / F1959M – 12 (The Standard Test Method for Determining the Arc Rating of Materials for Clothing) was in development, we quickly recognized that some materials would allow skin burn prediction to be reached before they “broke open” and others would not. Initially these became two ratings. One was called an ATPV and the other was called EBT.


ASTM Standards Definitions:

  • ATPV (Arc Thermal Performance Value) The incident energy on a material that results in a 50% probability that sufficient heat transfer through the specimen is predicted to cause the onset of second-degree burn injury based on the Stoll Curve, cal/cm².
  • Energy Breakopen Threshold (EBT) The incident energy on a material that results in a 50% probability of breakopen. Breakopen is defined as any open area at least 1.6 cm² (0.5 in.²)
