Subject: MeOH and Respirator Cartridges

Chemicals with high vapor pressures (e.g., methylene chloride, 
fluorocarbons) don't adhere to activated charcoal very well so 
air-purifying respirators are not advisable for them. NIOSH generally 
kicks you up to air-supplying respirators for them.

Peter Zavon is right, according to 29 CFR 1910.134, cartridge 
replacement must be guided by a changeout schedule. Most respirator 
manufacturers can provide them on discs or at their Web sites. If 
that doesn't work, try OSHA at:
