Hazards and Protection.
Store in a cool, dry place. Store in a tightly closed container. Keep under a nitrogen blanket.
Wash thoroughly after handling. Use only in a well ventilated area. Avoid contact with eyes, skin, and clothing. Avoid ingestion and inhalation. Do not allow contact with water.
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.
Absorb spill with inert material, (e.g., dry sand or earth), then place into a chemical waste container. Do not expose spill to water.
Stable under normal temperatures and pressures.
Metals, strong acids, strong bases, glass.
Hydrogen chloride, carbon monoxide, carbon dioxide, silicon oxide.
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Water Reactive. Material will react with water and may release a flammable and/or toxic gas. Substance is noncombustible. Extinguishing media: DO NOT USE WATER! For small fires, use carbon dioxide, dry chemical, dry sand, or alcohol-resistant foam.
Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes.
Contact with water in foam applied to adjacent fires will produce irritating fumes of hydrogen chloride.
Fire will produce irritating, corrosive and/or toxic gases.
May cause burns to the digestive tract.
May cause respiratory tract irritation. Causes chemical burns to the respiratory tract.
Contact with skin causes irritation and possible burns, especially if the skin is wet or moist.
Contact with eyes may cause severe irritation, and possible eye burns.
Do NOT induce vomiting and seek IMMEDIATE MEDICAL ADVICE.
Get medical aid immediately. Remove from exposure to fresh air immediately. If breathing is difficult, give oxygen.
Get medical aid immediately. Immediately flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes.
Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately.
