Today I was using a solvent to remove contact cement.  I borrowed a respirator with charcoal filters from my friend Eric.  It seemed to be working really well, as I couldn't smell a thing.  I am clausterphobic, and hate to have stuff over my face.  Still, I'm getting used to things like face cages on my sparring gear, that sort of thing, so I figured I could handle it. 

I put the respirator on, and started to work applying the solvent, and beginning the scraping.

Then, I started to feel lightheaded. Could it be that I had somehow put the repirator on wrong, or was using it wrong and was breathing solvent fumes after all?

Then, I realized that I was hyperventilating.  A few meditative breaths, and I was alright again.

Sheesh.

Still some stickyness on the surface in places...looks like I might have to go over it again another day.  But at least I know it works, and I can handle the job.
