First Aid Measures

Ingestion
Get medical aid immediately. Do NOT induce vomiting. If conscious and alert, rinse mouth and drink 2-4 cupfuls of milk or water.
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. Immediately flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes.
Eyes
Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately.

Handling and Storage

Storage
Keep away from sources of ignition. Store in a tightly closed container. Deep freeze (below -20 C). Store protected from light. Store under argon.
Handling
Do not breathe dust, vapor, mist, or gas. Do not get in eyes, on skin, or on clothing. Use only in a chemical fume hood.

Hazards Identification

Inhalation
Inhalation may be fatal as a result of spasm, inflammation, edema of the larynx and bronchi, chemical pneumonitis and pulmonary edema. Toxic if inhaled. May cause burning sensation, coughing, wheezing, laryngitis, shortness of breath, headache, nausea, and vomiting. Inhalation may cause sore throat, shortness of breath, labored breathing, coughing, and pulmonary edema.
Skin
May be harmful if absorbed through the skin. Causes irritation with burning pain, scaling, itching and redness. May cause erythema and blistering.
Eyes
May cause conjunctivitis. Causes redness and pain. Causes eye irritation and burns. May cause permanent corneal opacification.
Ingestion
May be harmful if swallowed. May cause irritation of the digestive tract and possible burns. May cause nausea, vomiting, headache, cramps, chills and drowsiness.
Hazards
Containers may explode. When heated to decomposition, it emits acrid smoke and fumes. Stable when stored at 41F. Avoid storing in areas of exposure to the direct rays of the sun and in areas of high fire hazard. Tends to polymerize on storage. Avoid elevated temperatures.

Exposure Controls/Personal Protection

Personal Protection
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.
Exposure Effects
May cause cancer in humans. Animal studies have reported the development of tumors.
Exposure limit(s)
TLV: 0.5 ppm; 1.5 mg/m3 A3 (ACGIH 1997). OSHA PEL: 1910.1013 See Appendix B NIOSH REL: Ca See Appendix A NIOSH IDLH: Potential occupational carcinogen N.D
Poison Class
1*

Fire Fighting Measures

Flash Point
74
Fire Fighting
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Will burn if involved in a fire. Combustible Liquid. Extinguishing media: Use water spray to cool fire-exposed containers. In case of fire use water spray, dry chemical, carbon dioxide, or chemical foam.
Upper exp. limit
25.1
Lower exp. limit
2.9
Fire Potential
Moderately flammable. Combustion with moderate heating.

Accidental Release Measures

Small spills/leaks
Avoid runoff into storm sewers and ditches which lead to waterways. Neutralize spill with sodium bicarbonate. Cover with sand, dry lime or soda ash and place in a closed container for disposal. Remove all sources of ignition. Provide ventilation.

Stability and Reactivity

Stability
Stable when stored at +5 C in glass containers.
Incompatibilities
Strong oxidizing agents, strong bases, strong acids, acetates, halogens, thiocyanates, 2-aminoethanol, ammonium hydroxide, aniline, chlorosulfonic acid, ethylene diamine, ethyleneimine, hydrochloric acid, hydrofluoric acid, nitric acid, oleum, pyridine, sodium hydroxide, sulfuric acid.
Decomposition
Carbon monoxide, carbon dioxide.
Combustion Products
Fire may produce irritating, corrosive and/or toxic gases.
