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.

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
Respiratory depression secondary to hypoxia may occur. CNS depression is secondary to hypoxia from methemoglobinemia. DNT was NOT teratogenic in rats, and had no effects in a 3- generation study in rats. Testicular effects have been seen in laboratory animals, but not in exposed workers.
