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 gloves to prevent skin exposure. Clothing: Wear appropriate protective clothing to minimize contact with skin.

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

There are no human or animal reports suggesting a teratogenic potential for carbon black.

Exposure limit(s)

Fire Fighting Measures

Autoignition

449

Fire Fighting

Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Dust can be an explosion hazard when exposed to heat or flame. Flammable solid. Can be easily ignited and burns vigorously. Extinguishing media: For small fires, use water spray, dry chemical, carbon dioxide or chemical foam.

Fire Potential

Slight risk when exposed to heat or flame. Carbon black can be ignited in the presence of open flames, and burns slowly with production of carbon monoxide.

Accidental Release Measures

Small spills/leaks

Vacuum or sweep up material and place into a suitable disposal container. Avoid generating dusty conditions.

Stability and Reactivity

Incompatibilities

May react vigorously or violently when mixed with strong oxidizing agents such as chlorates, bromates and nitrates, especially when heated. Incompatible with chlorinated paraffins, lead oxide, manganese oxide, iron oxide, liquid oxygen, oils, and moisture. .

Stability

Stable under normal temperatures and pressures.

Decomposition

Carbon monoxide, carbon dioxide.

Combustion Products

Toxic vapors and gases (e.g. carbon monoxide) may be released in a fire involving carbon black.
