Hazards Identification

Inhalation

May cause respiratory tract irritation. The toxicological properties of this substance have not been fully investigated.

Skin

May cause skin irritation. The toxicological properties of this material have not been fully investigated.

Eyes

May cause eye irritation.

Ingestion

May cause irritation of the digestive tract. The toxicological properties of this substance have not been fully investigated. Practically Nontoxic: probable oral lethal dose (human) is above 15 g/kg = greater than 1 Qt. (2.2 Lb) for a 70 kg (150 Lb) person.

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

A respiratory protection program that meets OSHA's 29 CFR 1910.134 and ANSI Z88.2 requirements or European Standard EN 149 must be followed whenever workplace conditions warrant a respirator's use.

Exposure Effects

Ingestion of large quantities will produce a laxative effect and may be irritating to the digestive tract. Esophageal, gastric, small intestinal and rectal obstruction may occur due to osmotic disturbance.

Poison Class

-

Fire Fighting Measures

Fire Fighting

Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Dusts at sufficient concentrations can form explosive mixtures with air. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Extinguishing media: Use agent most appropriate to extinguish fire. In case of fire use water spray, dry chemical, carbon dioxide, or appropriate foam.

Fire Potential

This material is probably combustible.

Accidental Release Measures

Small spills/leaks

Clean up spills immediately, using the appropriate protective equipment. Sweep up, then place into a suitable container for disposal. Avoid generating dusty conditions. Provide ventilation.

Stability and Reactivity

Incompatibilities

Calcium oxide, bleeching powder, perchlorates, perchloric acid, sodium chlorate, fluorine, nitric acid, sodium nitrite, sodium nitrate, strong oxidizing agents.

Stability

Stable under normal temperatures and pressures.

Decomposition

Carbon monoxide, carbon dioxide.
