Hazards Identification

Ingestion
The toxicological properties of this substance have not been fully investigated.
Inhalation
Inhalation of dust may cause respiratory tract irritation.
Skin
No information regarding skin irritation and other potential effects was found.
Eyes
This product contains a cationic dye. Similar dyes have caused permanant injury to the cornea and conjunctiva in documented exposure cases with human or rabbit eyes.

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.

Fire Fighting Measures

Fire Fighting
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. 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.

Accidental Release Measures

Small spills/leaks
Scoop up with a nonsparking tool, then place into a suitable container for disposal. Avoid generating dusty conditions.

Stability and Reactivity

Incompatibilities
Oxidizing agents.
Stability
Stable under normal temperatures and pressures.
Decomposition
Nitrogen oxides, irritating and toxic fumes and gases.
