The OSHA standards that recommend against contact lenses (Acrylonitrile,
Ethylene oxide, Dibromochloropropane (DBCP), 4,4'-Methylenedianiline,
1,3-Butadiene, and Methylene chloride) date from well before it was shown
that the presence or absence of contacts made no significant different in
most chemical exposure situations. So does the 1981 Prudent Practices.
