Hazards and Protection.
Keep away from heat, sparks, and flame. Keep away from sources of ignition. Do not store near combustible materials. Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances.
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.
Vacuum or sweep up material and place into a suitable disposal container. Avoid generating dusty conditions.
Stable under normal temperatures and pressures.
Aluminum + aluminum fluoride, aluminum + barium nitrate + potassium nitrate, aluminum powder + titanium dioxide, barium chromate + tungsten and/or titanium, boron + magnesium + silicon rubber, combustible materials, ethanol, ferrocenium diamminetetrakis (thiocyanato-N) chromate(1-), lavtose, metal powders, potassium hexacyanocobaltate, reductants, sulfur, titanium hydride.
Hydrogen chloride, oxides of potassium, oxides of chlorine.
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Oxidizer. Greatly increases the burning rate of combustible materials. Extinguishing media: Use water spray to cool fire-exposed containers. For large fires, use water spray or fog. For small fires, use dry chemical, carbon dioxide, halon, or water spray.
These substances will accelerate burning when involved in a fire.
These substances will accelerate burning when involved in a fire. Some may decompose explosively when heated or involved in a fire. May explode from heat or contamination. Some will react explosively with hydrocarbons (fuels). May ignite combustibles (wood, paper, oil, clothing, etc.). Containers may explode when heated. Runoff may create fire or explosion hazard.
Liberates toxic gases when involved in fire.
Prolonged or repeated skin contact may cause dermatitis. May cause anemia and other blood cell abnormalities.
May cause irritation of the digestive tract. May cause kidney damage. In higher doses as an antithyroid agent, it has been associated with gastric irritation, nausea, vomiting, fever, skin rashes, lymphadenopathy, nephrotic syndrome, and rarely leukpopenia, agranulocytosis, pancytopenia, and fatal aplastic 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.
Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid if cough or other symptoms appear.
Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Get medical aid if irritation develops or persists.
Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid.
