Respirator selections for dyeing

OK, I started worrying a bit about fumes created when I heat polyester on the heat press, in addition to the dust from the dried dyes. And I found the following PDF: http://multimedia.3m.com/mws/mediawebserver?mwsId=SSSSSu7zK1fslxtUN8tZnx_Uev7qe17zHvTSevTSeSSSSSS-- I plan to contact someone at 3M (if it’s possible) to be sure, but the guide indicates that an organic vapor cartridge should be worn when working with polyester resin for fiberglass. The chart is helpful anyway.
