I wanted to start working with Micarta and I have read the other posts about respirators. The problem I am running into is they all say that Home Deopt or Lowes should have a multi cartridge 1/2 mask with organic vapor cartiges that are rated for formaldehyde. I have been to both now and ever single organic vapor cartridge they sell says on the back in big bold letters that theye are not rated for formaldehyde. Do I need to go to a website to get these cartridges? Thanks for any clarification I can get, I only got one set o lungs and I am pretty shure my elementary school was riddled with asbestos already lol.
 
I have always used a dust collector rated for dust and radionucleids, in short form very fine toxic dusts. Can you smell odour through them..sure enough, just expell some natural biological gas near the filter and it does come through but the odour from micarta is pretty well stopped.

Funny you should talk about asbestos in schools but back in the 50's a lot of schools in our area used to bring asbestos cement into the classroom to use for art class.....dried fast so it could be molded and painted the same day. No respirators back then either.
 
check out the 3M 6000 series masks. you woud need a large mask unless you are a midget (no offense). Ther are options out there for filters. There are plain jane P100 rated particulate filters (to include oil based particles) which is the 2091 filter, and there is the 2097 which has organic vapor relief also, and the full blown 60296 model wiich has the P100 rated prefilter (think 2091) with the multigas protection. check the links below. I use the 2091 filter for basic grinding (to include micarta and stabilized wood), and the 60926 for anything else besides grinding/sanding. I am about to upgrade to the 7000 series mask so I can use a full faceshield and not have my breath fog up the thing. The 7000 directs your exhaust breath down compared to the 6000 straight out. so to recap, for basic grinding, all you need is a basic particulate filter (2091). anything that involves true vapors, the 60926.

3m 6000 series and 2097 here as well. good stuff! and it will fit under some welding helmets and face masks. The 60926 filters sound like something I'm gonna need to check out, thanks gixxer!
 
Thanks guys, I got a North 1/2 face from my local fire and safety and they have every imaginable combo of carts. I like the north P100 carts because they are small thin and cheap. I had heard soem comercial micartas and other synthetics could produce some bad vapor from the heating of the chemicals in the epoxies and such. Dont know how accurate that is but I figured it was better to be able to get FM OV rated carts just incase.
 
guess you have a point if you are heating up the micarta during grinding till the stuff smokes. I burned in a tang on a piece of stabilized wood 2 weeks ago, and that stuff was horrible smelling! I did not have any of the multigas carts on hand at the time, only the 2091.
