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

Abnormally low blood pressure, reduced body temperature, rapid breathing, and rapid heart rate may develop with severe toxicity. Initial CNS excitation, including seizures, is commonly followed by CNS depression ranging from lethargy to coma and death. Fetotoxicity and skeletal abnormalities have been reported in animal experiments.
