Properties.

Hazards and Protection.
Storage
Keep in a cool, dry, dark location in a tightly sealed container or cylinder. Keep away from incompatible materials, ignition sources and untrained individuals. Secure and label area. Protect containers/cylinders from physical damage.
Handling
All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood.
Protection
Wear appropriate protective gloves, clothing and goggles.
Respirators
Wear positive pressure self-contained breathing apparatus (SCBA).
Small spills/leaks
Wear a fully encapsulating, vapor protective clothing should be worn for spills and leaks with no fire. Prevent contact unless wearing appropriate protective clothing. Stop leak if you can do it without risk. Use water spray to reduce vapors; do not put water directly on leak, spill area or inside container. Keep combustibles (wood, paper, oil, etc.) away from spilled material. Cover with DRY earth, DRY sand, or other non-combustible material followed with plastic sheet to minimize spreading or contact with rain. Use clean non-sparking tools to collect material and place it into loosley covered plastic containers for later disposal.
Stability
No data.
Decomposition
Produces hydrochloric acid when exposed to water.

Fire.
Fire fighting
When material is not involved in fire: do not use water on material itself. Small Fires: Dry chemical or carbon dioxide. Large Fires: Flood fire area with large quantities of water, while knocking down vapors with water fog. If insufficient water supply: knock down vapors only.
Fire potential
May burn but not ignite readily. May ignite combustibles (wood, paper, oil, clothing, etc.).
Hazards
Substance will react with water (some violently), releasing corrosiveand/or toxic gases.
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.

First aid
 
   Ingestion
Treat ingestions of greater than 40 milligrams per kilogram with decontamination of the stomach if within 4 hours of ingestion. Administer charcoal as a slurry.
   Inhalation
Move victim to fresh air. Apply artificial respiration if victim is not breathing. Do not use mouth-to-mouth method if victim ingested or inhaled the substance; induce artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device.Administer oxygen if breathing is difficult.
   Skin
