I remember there were studies (from a while ago) indicating that a 10-minute soak in a solution of 10% household bleach in water reduces a nylon rope's strength by only a few percent at most. I know that this is part of the disinfection protocol that some rescue teams use. So while there is still much danger presented by bleach to ropes, this specific exposure is OK.
Well, this specific exposure is also one of the ways you can perform decontamination
to control the possible human-mediated spread of WNS
according to the U.S. Fish and Wildlife Service
Presumably other nylon items, like webbing and harnesses, would react similarly, and they could be safely decontaminated in this manner.
SUOC gear has been caved with in the northeast. We have some gear that's not been used, and other gear that we have ordered recently, so not all of our gear will have to be decontaminated before we go to TAG this winter, but much of it will.
The thing is, many of our harnesses are Petzl Fractios
, and these harnesses are made of polyester.
Have there been studies done on the effect of a 10-minute soak in 10% household bleach solution, on polyester?
I'm interested in anything any of you know about this. However, Hank, if you could tell me something in your official capacity as a Petzl representative (or otherwise), I would appreciate it.
If I don't get the needed information through this post then of course I will follow the "proper procedure" and contact Petzl directly. But right now, I want to solicit both "official" and "unofficial" information on this matter.
