Dangers of Improper Wear Flash Fire: Episode 4 – Consequences of Wearing the Wrong Rainwear

Tyndale’s Dangers of Improper Wear: Flash Fire series uses flash fire video footage shot at Texas A&M TEEX Fire Training Field to illustrate the severe consequences of incorrectly wearing flame resistant clothing (FRC). Each episode features insightful commentary from Tyndale’s arc-rated and flame resistant (AR / FR) clothing industry expert, Scott Margolin, Vice President of Corporate Strategy & Technical, who explains why it’s crucial to wear appropriate FRC and wear it properly.

Flame resistant (FR) rainwear that meets the proper ASTM standard is essential for anyone working in an environment with potential flash fire hazards. However, not all rainwear labeled as flame resistant is created equal. Read on to understand why it’s crucial to wear rainwear that meets ASTM F2733: the Standard Specification for Flame Resistant Rainwear for Protection Against Flame Hazards, and see the devastating results that could occur if you accidently wear insufficient rainwear on the job.

The Improper Wear Mistake

See what happens during a flash fire when FR rainwear isn’t tested to the appropriate standard:

As you can see, the consequences of wearing rainwear that claims to be flame resistant but does not meet the appropriate standard can be severe.

In the video above, the manikin is wearing rainwear certified to ASTM D6413: the Standard Test Method for Flame Resistance of Textiles (Vertical Test), which is only a component of proper FR rainwear testing and is not an appropriate indicator of protection on its own. It’s clear to see why ensuring your rainwear meets the appropriate standard is so critical. When exposed to a flash fire, the ASTM D6413 rainwear quickly disintegrates and catches fire, causing significant smoke and the need for physical extinguishing.

The Correct Action

In contrast, rainwear that meets ASTM F2733 is designed specifically for specialized rainwear fabrics and protection against flame hazards. This next-generation, rainwear-specific standard includes both the D6413 vertical flame test AND ASTM F1930 (the “manikin test”) for flash fire rainwear.

The difference is clear in the video: the manikin wearing F2733-certified rainwear experiences little after flame, quickly self-extinguishing. The garment remains intact and does not disintegrate, shrink, or discolor.

The appropriate standard for flash fire rainwear is ASTM F2733, and if you face a flash fire hazard on the job it's essential to check that any rainwear you purchase meets this standard.

ASTM F2733 rainwear provides superior protection, durability, and comfort, ensuring you're safe and comfortable while on the job. Don't take any chances when it comes to your safety – make sure your rainwear is certified to the appropriate standard for your hazard.


Dangers of Improper Wear

Have you ever made the mistake of wearing flammable clothing on the job, or neglected to tuck in your flame-resistant shirt, or even worn a flammable sweatshirt over your protective clothing when exposed to potential flash fire or arc flash hazards? If so, you're not alone. Good news is it didn’t lead to a serious injury. Bad news is, next time you might not be so lucky. Regardless of the type of hazard, there are important lessons to be learned. We have identified common mistakes made in each situation. Watch and learn – it could save your life.
