First Aid Measures

Ingestion
If victim is conscious and alert, give 2-4 cupfuls of milk or water. Get medical aid immediately.
Inhalation
Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid.
Skin
Immediately flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Get medical aid if irritation develops or persists.
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. Refrigerator (approx 4 C).
Handling
Wash thoroughly after handling. Use spark-proof tools and explosion proof equipment. Avoid contact with eyes, skin, and clothing. Avoid contact with heat, sparks and flame. Avoid ingestion and inhalation. Use only in a chemical fume hood.

Hazards Identification

Ingestion
The toxicological properties of this substance have not been fully investigated. May cause headache. May cause nausea and vomiting.
Inhalation
May cause respiratory tract irritation. The toxicological properties of this substance have not been fully investigated.
Skin
May cause skin irritation.
Eyes
May cause eye irritation.
Hazards
Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion and poison hazard indoors, outdoors or in sewers.

Exposure Controls/Personal Protection

Personal 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.

Fire Fighting Measures

Flash Point
56
Fire Fighting
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Combustible Liquid. To extinguish fire use water spray, dry chemical, carbon dioxide, or chemical foam.
Fire Potential
HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames.

Accidental Release Measures

Small spills/leaks
Absorb spill with inert material, (e.g., dry sand or earth), then place into a chemical waste container. Wash area with soap and water. Remove all sources of ignition. Use a spark-proof tool. Provide ventilation.

Stability and Reactivity

Stability
Stable under normal temperatures and pressures.
Incompatibilities
Strong bases; strong oxidizing agents; strong reducing agents.
Decomposition
Carbon monoxide, oxides of sulfur, carbon dioxide, hydrogen bromide, hydrogen sulfide.
Combustion Products
Fire will produce irritating, corrosive and/or toxic gases.
