Hazards and Protection.
Storage
Do not store near combustible materials. Store in a cool, dry, well-ventilated area away from incompatible substances. Keep away from water. Keep away from metals. Corrosives area. Keep containers tightly closed.
Handling
Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use with adequate ventilation. Do not allow water to get into the container because of violent reaction. Do not get in eyes, on skin, or on clothing. Do not ingest or inhale. Wash clothing before reuse. Keep away from clothing and other combustible materials. Discard contaminated shoes.
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 prevent skin exposure.
Respirators
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.
Small spills/leaks
Do not flush into a sewer. Clean up spills immediately, using the appropriate protective equipment. Absorb spill using an absorbent, non-combustible material such as earth, sand, or vermiculite. Isolate area and deny entry. Provide ventilation. Do not expose spill to water.
Stability
Stable at room temperature in closed containers under normal storage and handling conditions.
Incompatibilities
Alcohols, ammonia, reactive metals, water.
Decomposition
Hydrogen chloride, irritating and toxic fumes and gases, chloride fumes, titanium oxychlorides.

Fire.
Fire fighting
Not flammable. For small fires, use dry chemical or carbon dioxide. For large fires, flood fire area with water from a distance. Do not get solid streams of water on spilled material. Move container from fire area if this can be done without risk. Cool containers exposed to flames with water until well after fire is out.
Fire potential
Nonflammable.
Hazards
Material will react with water to produce hydrochloric acid. It may ignite other combustible materials (e.g., wood, oil, etc.). Flammable, poisonous gases may accumulate in tanks and hopper cars. Runoff to sewer may create fire or explosion hazard. Reacts strongly with water to release hydrochloric acid and heat. Avoid water, moist air. Stable in concentrated aqueous solutions. Avoid contact with moisture; the chemical absorbs moisture from air and evolves dense white fumes.
Combustion products
Fire will produce irritating, corrosive and/or toxic gases. Reaction with water may generate much heat which will increase the concentration of fumes in the air.

Exposure effects
Fever may develop from acute inhalation exposure. No data were available to assess the teratogenic potential of this agent. <br>No data were available to assess the potential effects of exposure to this agent during pregnancy or lactation. <br>No information about possible male reproductive effects was found in available references.
   Ingestion
Causes gastrointestinal tract burns. May cause perforation of the digestive tract.
   Inhalation
May be fatal if inhaled. Effects may be delayed. Causes chemical burns to the respiratory tract. May cause lung damage. Inhalation may be fatal as a result of spasm, inflammation, edema of the larynx and bronchi, chemical pneumonitis and pulmonary edema.
   Skin
Contact with liquid is corrosive and causes severe burns and ulceration.
   Eyes
Causes severe eye burns. May cause irreversible eye injury.

First aid
 
   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 not breathing, give artificial respiration. If breathing is difficult, give oxygen.
   Skin
Get medical aid immediately. Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse. SPEEDY ACTION IS CRITICAL! Destroy contaminated shoes.
   Eyes
Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately. Do NOT allow victim to rub or keep eyes closed.
