[Woodcarver] A likely answer - CA glue on Kevlar glove

[Matt Kelley]

Hi Sandy and everyone -

Interesting variation of the problem.

As the ever diligent editor,  I feel back on my safety management 
days and did a search of vendors and looked at some Material Safety 
Data Sheets.  I ended up at the 3-M site, as they do a better job 
then most.

The MSDS for one of their cyanoacrylate glues states the following:

"OTHER PRECAUTIONARY INFORMATION:
Contact with cotton or wool may result in a strong exothermic 
reaction which can cause burns or fire."


So there we have the answer!   Likely both the Kevlar glove and 
Sandy's rag contained some amount of cotton.

If anyone else has had similar incidents I'd like to hear about them 
-  there will be an article about this problem in the next issue of 
WOM,  as well as a new entry in the Resource Files.

Carve On - Safely!!
Matt
