Hazards and Protection.
Storage
Keep container tightly closed.
Protection
Compatible chemical-resistant gloves. Chemical safety goggles. Face shield (8-inch minimum). 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
Cover with dry lime or soda ash, pick up, keep in a closed container, and hold for waste disposal. Ventilate area and wash spill site after material pickup is complete.
Stability
Stable at normal temperatures and pressures.
Incompatibilities
Strong oxidizing agents, strong acids.
Decomposition
Oxides of carbon, oxides of nitrogen.

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
Combustible liquid.
Hazards
Emits toxic fumes under fire conditions.

Health.
Exposure effects
Material is extremely destructive to tissue of the mucous membranes and upper respiratory tract, eyes, and skin. Inhalation may result in spasm, inflammation and edema of the larynx and bronchi, chemical pneumonitis, and pulmonary edema. Symptoms of exposure may include burning sensation, coughing, wheezing, laryngitis, shortness of breath, headache, nausea, and vomiting.
   Ingestion
Harmful if swallowed.
   Inhalation
May be harmful if inhaled. Material is extremely destructive to the tissue of the mucous membranes and upper respiratory tract.
   Skin
Causes burns. May be harmful if absorbed through the skin.
   Eyes
Causes burns.

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.
