First Aid Measures

Ingestion
Do NOT induce vomiting. 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.
Inhalation
Get medical aid immediately. Remove from exposure to fresh air immediately. If breathing is difficult, give oxygen. DO NOT use mouth-to-mouth respiration. If breathing has ceased apply artificial respiration using oxygen and a suitable mechanical device such as a bag and a mask.
Skin
Get medical aid immediately. Immediately flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse. Destroy contaminated shoes.
Eyes
Get medical aid immediately. Do NOT allow victim to rub or keep eyes closed. Extensive irrigation is required (at least 30 minutes).

Handling and Storage

Storage
Keep container closed when not in use. Corrosives area. Refrigerator (approx 4 C). Store protected from moisture.
Handling
Keep container tightly closed. Do not get on skin or in eyes. Do not ingest or inhale. Use with adequate ventilation. Do not allow contact with water. Discard contaminated shoes. Keep from contact with moist air and steam.

Hazards Identification

Inhalation
May cause severe irritation of the respiratory tract with sore throat, coughing, shortness of breath and delayed lung edema. Causes chemical burns to the respiratory tract. Aspiration may lead to pulmonary edema. May cause systemic effects.
Skin
Causes skin burns. May cause skin rash (in milder cases), and cold and clammy skin with cyanosis or pale color.
Eyes
Causes eye burns. Lachrymator. May cause chemical conjunctivitis and corneal damage.
Ingestion
May cause severe and permanent damage to the digestive tract. Causes gastrointestinal tract burns. May cause perforation of the digestive tract. May cause systemic effects.
Hazards
Contact with metals may evolve flammable hydrogen gas.

Exposure Controls/Personal Protection

Personal Protection
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 minimize contact with skin.
Respirators
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.
Exposure Effects
Effects may be delayed.

Fire Fighting Measures

Flash Point
112
Fire Fighting
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Containers may explode when heated. Extinguishing media: If water is the only media available, use in flooding amounts. Do NOT get water inside containers. Cool containers with flooding quantities of water until well after fire is out. In case of fire, use carbon dioxide or dry chemical.
Fire Potential
Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes.

Accidental Release Measures

Small spills/leaks
Absorb spill with inert material, (e.g., dry sand or earth), then place into a chemical waste container. Avoid runoff into storm sewers and ditches which lead to waterways. Clean up spills immediately, using the appropriate protective equipment. Remove all sources of ignition. Provide ventilation. Do not get water inside containers.

Stability and Reactivity

Incompatibilities
Moisture, alcohols, oxidizing agents, strong bases.
Stability
Stable at room temperature in closed containers under normal storage and handling conditions.
Decomposition
Hydrogen chloride, carbon monoxide, irritating and toxic fumes and gases, carbon dioxide.
Combustion Products
Fire may produce irritating, corrosive and/or toxic gases.
