Hazards and Protection.
Storage
Keep tightly closed. Keep away from heat, sparks, and open flame.
Protection
Compatible chemical-resistant gloves. Chemical safety goggles. Protective clothing.
Respirators
Use respirators and components tested and approved under appropriate government standards such as NIOSH (US) or CEN (EU). Where risk assessment shows air-purifying respirators are appropriate use a full-face respirator with multi-purpose combination (US) or type ABEK (EN 14387) respirator cartridges as a backup to engineering controls. If the respirator is the sole means of protection, use a full-face supplied air respirator.
Small spills/leaks
Absorb on sand or vermiculite and place in closed containers for disposal. Ventilate area and wash spill site after material pickup is complete.
Stability
Stable at normal temperatures and pressures.
Incompatibilities
Moisture sensitive. Keep away from strong oxidizing agents and strong bases.
Decomposition
Carbon monoxide, Carbon dioxide, Hydrogen chloride gas.

Fire fighting
For small (incipient) fires, use media such as alcohol foam, dry chemical, or carbon dioxide. For large fires, apply water from as far as possible. Use very large quantities (flooding) of water applied as a mist or spray; solid streams of water may be ineffective. Cool all affected containers with flooding quantities of water. Wear self-contained breathing apparatus and protective clothing to prevent contact with skin and eyes.
Fire potential
Cumbustible liquid.
Hazards
Emits toxic fumes under fire conditions.

Health.
Exposure effects
   Ingestion
Harmful if swallowed.
   Inhalation
May be harmful if inhaled. Material is irritating to mucous membranes and upper respiratory tract.
   Skin
Causes skin irritation. May be harmful if absorbed through the skin.
   Eyes
Lachrymator. Causes eye irritation.

First aid
 
   Ingestion
If swallowed, wash out mouth with water provided person is conscious. Call a physician.
   Inhalation
If inhaled, remove to fresh air. If not breathing give artificial respiration. If breathing is difficult, give oxygen.
   Skin
In case of contact, immediately wash skin with soap and copious amounts of water. Remove contaminated clothing and shoes. Call a physician.
   Eyes
In case of contact with eyes, flush with copious amounts of water for at least 15 minutes. Assure adequate flushing by separating the eyelids with fingers. Call a physician.
