Methanol

CAS RN: 67-56-1

Protective Equip. / Clothing

Eye/face protection: Face shield and safety glasses. Use equipment for eye protection tested and approved under appropriate government standards such as NIOSH (US) or EN 166(EU).
Skin protection: Handle with gloves.
Body Protection: Complete suit protecting against chemicals. Flame retardant antistatic protective clothing. The type of protective equipment must be selected according to the concentration and amount of the dangerous substance at the specific workplace.
Respiratory protection: Where risk assessment shows air-purifying respirators are appropriate use a full-face respirator with multipurpose combination (US) or type AXBEK (EN 14387) respirator cartridges as a backup to engineering controls. If the respirator is the sole means of protection, use a full-face supplied air respirator. Use respirators and components tested and approved under appropriate government standards such as NIOSH (US) or CEN (EU).
Personnel protection: ... Wear appropriate chemical protective gloves, boots, and goggles.
There is some data suggesting that the breakthrough times of methanol through natural rubber are approximately an hour or more.
Breakthrough times of methanol through nitrile or Viton are greater than one hour reported by (normally) two or more testers.
Breakthrough times of methanol through polyvinyl alcohol or polyvinyl chloride are less (usually significantly less) than one hour reported by (normally) two or more testers.
