Thermo-man Videos

Yesterday, June 26th, we burned up a lot of clothing in an effort to show what various materials do when exposed to fire. We exposed untreated cotton, treated cotton, Nomex, Nomex with an FR undercoat, a Tychem chemical protection suit and a Dupont ThermalPro chemical suit to 1,700 degrees of flames for 4 seconds. The results were pretty impressive.

Rather than tell you all about it, however, I’m going to let you view the results for yourself.

Here is the list along with the link to the Youtube video that we uploaded last night after all the burning was done:

· Untreated cotton shirt and jeans

· Treated cotton

· Nomex

· Nomex with Under Armour

· Tychem Chemical Suit

· Tychem ThermoPro Protective Suit

Now the question you’ve got to ask yourself is “If I was going to send my 18-year old daughter/son off to work in a refinery what garment would I want them to be wearing?”

Come join NSA as we discuss our flame resistant hi-visibility garments, ranging from our widely used HRC 1 mesh vests to our warm, rugged HRC 2 sweatshirts.

Our FR & Hi-Visibility Dual Action garments meet the requirements of ISEA/ANSI 107-2010, NFPA 70E level 2 and ASTM 1506 for Flame Resistance and other performance measures.

We will also touch on key industry standards and who they apply to.  

Key Discussions:
• ANSI 107 & NFPA 70E update
• NSA’s product offering
• Functionality & key characteristics

Thanks for joining us!

Free Beta Software for Calculating Arc Flash

If you are involved with electrical work you need to check out the blog at

It focuses exclusively on arc flash, its dangers, prevention, etc… Additionally, they’ve got a free beta version of an arc flash calculation software that you can download free in exchange for feedback.

Arcad, the company that provides this blog and free software “helps facilities create safer working environments for individuals who service electrical systems by providing On-Line and PC based software tools for Short Circuit and Arc Flash Hazard Analysis. NFPA requires that any panel likely to be serviced by a worker be surveyed and labeled. ARCAD service includes resources and tools allowing plant and facility managers and personnel to perform short circuit, incident energy, arc flash protection boundary, level of PPE calculations, and create customized arc flash warning labels themselves drastically reducing the cost of getting in compliance with OSHA & NFPA 70E”

Have a look around (It’s a Canadian company but the information applies here in the U.S. as well), and download the free software. Don’t forget to go back and give them feedback, it’s the least you can do to thank them for the free download.

FR clothing… all the way or not at all!

You’d have to be living somewhere in upper Mongolia in a cave for the past decade not to know about the new standards and safety measures concerning Flame Retardant clothing that have been enacted and which are still in the works.

Being aware of the changes and standards is one thing, understanding them properly is quite another. I’m referring specifically to the issue of FR underclothing.

Many people don’t realize that, when dealing with arc flash, it isn’t enough to wear FR outerwear only. In case of the type of electrical power involved in an arc flash, your underclothing is just as much an issue as your outerwear. The outerwear may not catch fire and/or continue burning but the energy will go through to the underclothing. If you are wearing cotton or polyester under the outerwear, especially right up against the skin, these garments can ignite and/or melt and cause serious burns.

For this reason, it is important to dress appropriately if you are dressing to protect against arc flash.

Fortunately, there are FR underclothing options. Clothing such as the 5 cal flame retardant 2nd Skin by Benchmark is a great, comfortable solution to the problem.

There are also FR bras available online for the ladies.

With FR clothing, its about protection all the way down, through all the layers, not just the outerwear.

Arc Flash Video by NIOSH

An arc flash is the sudden release of electrical energy through the air when a high-voltage gap exists and there is a breakdown between conductors. An arc flash gives off thermal radiation (heat) and bright, intense light that can cause burns. Temperatures have been recorded as high as 35,000 °F. High-voltage arcs can also produce considerable pressure waves by rapidly heating the air and creating a blast. This pressure burst can hit a worker with great force and send molten metal droplets from melted copper and aluminum electrical components great distances at extremely high velocities.

This video is available for viewing on the NIOSH website.

Beware of misleading FR labels!!!!

Are you in the market for Flame Retardant safety vests or garments for yourself or for your workers?

There is something important to be aware of before you make your purchase because not all FR ratings are created equal. What you will often find when you look at the label of the garment is that the FR rating referenced is NFPA 701.

You might be asking “So what? Why is this a problem? It’s NFPA isn’t it?” The reason that it’s a problem is because NFPA 701 is a standard that was developed years ago to test hotel draperies and curtains, not clothing! Check it out on the NFPA website.

The problem is that this standard isn’t strict enough to apply to clothing. Some Clothing manufacturers, however, are using it to sell polyester garments. All polyester will melt and drip. You do not want to be wearing polyester if you are going to be exposed to flames, no matter what the manufacturer tries to tell you about its FR properties.

At issue is the fact that other fibers that have inherent FR qualities are more expensive than polyester and, in the battle to sell more FR vests and garments, cheaper often wins the bid, particularly when the buyer doesn’t know the difference between the various standards.

So before you purchase a FR garment, make sure you know what standard is being referenced. It makes a world of difference!
