Re: flight suits



To All,

I disagree with the statement that Nomex only protects you in the case of flash fires.  Nomex flight suits protect in more than  flash fires.  There are numerous accounts of personnel surviving after being caught in post crash and refueling fires where they needed to evacuate the aircraft through flames.  These were more than flash fires.  What has been learned from most aircraft fires is that;
1.  you must evacuate the flames as soon as possible, and,
2.  for survivable fires, what you are wearing under the Nomex flight suit will make a difference in your recovery.  The skin behind any area on a flight suit that has a single layer of Nomex is subject to direct heat transfer which can be bad.  Those areas of the body that have a layer of cotton behind the Nomex receive less burn damage.

Is it in the name of saving money that programs willingly gamble with their lives of their employees?  I know there is a low rate of aircraft fires with the improvement of fuel cells and break away fittings, but do people think you only have post crash fires during non survivable accidents?  A poly-cotton flight suit might look and feel nice, but what personal protective value does it provide?  Have you ever seen how polyester melts into the skin?

Last point-Nomex IIIA flight suits can be tumbled dry on low heat.

The point that everyone must remember is that Nomex only protects you in the case of flash fires and with a true blaze, there is little protection. Nomex was originally developed when military helicopters had problems with flash fires in the cockpit. Nomex must also be laundered correctly and hung to dry to preserve the Nomex fire retardant. When I came to my present program, they were wearing short sleeved Nomex at almost 1/3 the price of poly-cotton suits. I also wondered why suffer the extra expense and then wear short sleeves or roll them up. Seemed to be counterproductive. We now wear the poly-cotton and are very happy with them. I will tell you that there is no one "Wonder Flight Suit Company". They all have issues. Deb Milliner
