Hazards and Protection.
Storage
Keep container closed when not in use. Corrosives area. Store protected from moisture. Store in a cool, dry area away from incompatible substances.
Handling
Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Do not get in eyes, on skin, or on clothing. Keep container tightly closed. 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.
Protection
Eyes: Wear safety glasses and chemical goggles if splashing is possible. 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.

Stability
Stable under normal temperatures and pressures.
Incompatibilities
Strong oxidizing agents, moisture.
Decomposition
Hydrogen chloride, carbon monoxide, oxides of sulfur, irritating and toxic fumes and gases, carbon dioxide.

Fire.
Fire fighting
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. To extinguish fire, use water, dry chemical, chemical foam, or alcohol-resistant foam. Do NOT get water inside containers.

Health.
Exposure effects
Effects may be delayed.
   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.
   Inhalation
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. May cause chemical conjunctivitis and corneal damage.
