Exposure Controls/Personal Protection

Personal Protection

Eyes: Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166. Skin: Wear appropriate protective gloves to prevent skin exposure. Clothing: Wear appropriate protective clothing to prevent skin exposure.

Respirators

Follow the OSHA respirator regulations found in 29CFR 1910.134 or European Standard EN 149. Always use a NIOSH or European Standard EN 149 approved respirator when necessary.

Exposure Effects

The phthalimide fungicides contain the phthalimide moiety in common with phthalidomide, a known human teratogen. Captan has been teratogenic, fetotoxic, and/or embryotoxic in a variety of rodent species and caused stillbirths in dogs. Folpet was teratogenic in rabbits, chicks, and hamsters. Captafol has been embryo- or fetotoxic in experimental animals. <br>Captan, folpet, and captafol have all induced testicular degeneration in laboratory animals.
