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

Dizziness occurred in a human exposure to 10 g of dbp. Polyneuritis was reported in one soviet study. There have been several animal and laboratory tests done on the possible teratogenic effect of DBP. The results have been mixed. Studies done on Salmonella cultures have shown mildly positive mutagenic responses. DBP appears to affect females more than males, at least in the rodent studies performed.
