Wash thoroughly after handling. Use with adequate ventilation. Minimize dust generation and accumulation. Avoid contact with eyes, skin, and clothing. Keep container tightly closed. Avoid ingestion and inhalation.
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.
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.
Sweep up or absorb material, then place into a suitable clean, dry, closed container for disposal. Avoid generating dusty conditions.
Stable under normal shipping and handling conditions.
Strong oxidizing agents.
Nitrogen oxides, carbon monoxide, carbon dioxide.
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. To extinguish fire use water spray, dry chemical, carbon dioxide, or chemical foam.
Slight fire hazard.
Fire may produce irritating, corrosive and/or toxic gases.
May cause bone marrow abnormalities with damage to blood forming tissues.
May cause gastrointestinal irritation with nausea, vomiting and diarrhea. May cause kidney damage. May cause systemic toxicity with acidosis. Exposure may cause anemia and other blood abnormalities. May produce aplastic anemia, blood pressure depression, body temperature decrease, changes in kidnet tubules, dyspnea, flaccid paralysis without anesthesia, gastrointestinal effects, kidney damage and hemorrhaging, muscle contraction or spasticity, muscle weakness, nausea, vomiting, respiratory stimulation and somnolence. Prolonged ingestion may produce bone marrow depression with agranulocytosis, thrombocytopenia, leukopenia and aplastic anemia may occur with prolonged administration. Lab findings in overdoses have indicated metabolic acidosis, hyponatremia, hypokalemia, bone marrow hypoplasia, thrombocytopenia, granulocytopenia, coagulopathy, and less commonly hemolytic anemia.
Causes respiratory tract irritation.
Causes skin irritation.
Causes eye irritation.
If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Get medical aid immediately.
Remove from exposure to fresh air immediately. Get medical aid if cough or other symptoms appear.
Get medical aid if irritation develops or persists. Flush skin with plenty of soap and water.
Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately.
