Hazards and Protection.
Keep from contact with oxidizing materials. Store in a cool, dry, well-ventilated area away from incompatible substances.
Wash thoroughly after handling. Minimize dust generation and accumulation. Avoid contact with eyes, skin, and clothing. Keep container tightly closed. Avoid ingestion and inhalation. Use with adequate ventilation. Wash clothing before reuse.
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.
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.
Wash area with soap and water. 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.
Stable at room temperature in closed containers under normal storage and handling conditions.
Strong oxidizing agents.
Carbon monoxide, oxides of nitrogen, irritating and toxic fumes and gases, carbon dioxide.
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. To extinguish fire use water spray, dry chemical, carbon dioxide, or appropriate foam.
3 (Strong toxins)
May cause fetal effects. Effects may be delayed.
May cause gastrointestinal irritation with nausea, vomiting and diarrhea. May be harmful if swallowed.
Causes respiratory tract irritation. The toxicological properties of this substance have not been fully investigated. Can produce delayed pulmonary edema.
Causes skin irritation. Prolonged and/or repeated contact may cause irritation and/or dermatitis.
Causes eye irritation. 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. May cause chemical conjunctivitis.
Get medical aid immediately. Induce vomiting by giving one teaspoon of Syrup of Ipecac.
Get medical aid immediately. Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen.
Get medical aid. Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse.
