Hazards and Protection.
Keep away from sources of ignition. Store in a tightly closed container. Store in a dry area. Keep under an argon blanket. Refrigerator (approx 4 C).
Use spark-proof tools and explosion proof equipment. Do not breathe dust, vapor, mist, or gas. Do not get in eyes, on skin, or on clothing. Use only in a chemical fume hood.
Skin: Wear appropriate protective gloves to prevent skin exposure. Clothing: Wear appropriate protective clothing to minimize contact with skin.
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. Remove all sources of ignition. Use a spark-proof tool.
Reacts slowly with water to form hydrochloric acid.
Strong oxidizing agents, strong bases.
Hydrogen chloride, carbon monoxide, carbon dioxide.
Upper exp. limit, %
Lower exp. limit, %
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Will burn if involved in a fire. To extinguish fire use water spray, dry chemical, carbon dioxide, or chemical foam.
The material will burn, though it may require some effort to ignite. Fire produces irritating and poisonous gases. When heated to decomposition, it emits toxic fumes of chlorine-containing compounds.
Fire may produce irritating, corrosive and/or toxic gases.
May cause cancer in humans.
Poison by ingestion. Causes gastrointestinal tract burns.
May be fatal if inhaled. Causes chemical burns to the respiratory tract. May cause abdominal pain, nausea, vomiting, and inflammation of the gums and mouth.
Causes skin burns. Toxic in contact with skin.
Causes eye burns. Lachrymator.
Do NOT induce vomiting. If victim is conscious and alert, give 2-4 cupfuls of milk or water. SPEED IS ESSENTIAL. A DOCTOR MUST BE NOTIFIED AT ONCE.
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 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.
