Don't get burned by your disposable coverall...

Pyrolon disposable protective garments can be worn over Thermal Protective Garments without compromising thermal protection.

In fact, not only does Pyrolon provide protection against liquid splashes (Types 3, 4, 5 and 6), but when worn over a TPG can actually increase overall thermal protection.

Thermal Mannequin Testing has shown conclusively that Pyrolon could be the difference between a life and death scenario when worn as a replacement for a standard disposable worn over a TPG.

Predicted Body Burn (PBB) from thermal mannequin testing shows the effect of wearing different coveralls over a Nomex IIIA Thermal Protective garment.

 The Nomex TPG alone results
in a PBB of 37%.

 Wearing a PE film (in this case a microporous film) / Polyproylene laminate - commonly used for Type 5 & 6 coveralls - results in an increase in PBB to 53%... Almost certainly fatal. Heavier disposables, with more materials to burn, would tend to result in an even higher PBB.

A Pyrolon CRFR coverall worn over Nomex IIIA for Type 3 & 4 chemical protection results in a reduction of PBB

 A Pyrolon XT coverall worn over Nomex IIIA for Type 5 & 6 splash protection results in a reduction of PBB to just 16%.

Are some standard disposables flame retardent?

Some types of standard disposables are classed as flame retardent and some even meet the the same FR standard (EN 533 Index 1) as Pyrolon.

However, in such products the flame retardency is based on the fabric tendancy to shrink from the flame and self extinguish. Simple testing demonstrates that if ignition is forced... if the flame stays in contact for several seconds, the material will ignite, burn and drip burning debris like any other disposable. Unfortunately the EN 533 test does not define a forced ignition so does not demonstrate this, allowing a claim of flame retardency for a fabric THAT WILL BURN...
