First Aid MeasuresBack to Contents
【Ingestion】

Never give anything by mouth to an unconscious person. Get medical aid. Do NOT induce vomiting. If conscious and alert, rinse mouth and drink 2-4 cupfuls of milk or water.
【Inhalation】

Remove from exposure to fresh air immediately. If breathing is difficult, give oxygen. Get medical aid. DO NOT use mouth-to-mouth respiration.
【Skin】

Get medical aid. Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse.
【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 StorageBack to Contents
【Storage】

Keep away from heat, sparks, and flame. Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances.
【Handling】

Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Avoid contact with eyes, skin, and clothing. Empty containers retain product residue, (liquid and/or vapor), and can be dangerous. Avoid contact with heat, sparks and flame. Avoid ingestion and inhalation. Use only in a chemical fume hood. Do not pressurize, cut, weld, braze, solder, drill, grind, or expose empty containers to heat, sparks or open flames.
Hazards IdentificationBack to Contents
【Inhalation】

Causes respiratory tract irritation. Can produce delayed pulmonary edema. Inhalation at high concentrations may cause CNS depression and asphixiation.
【Skin】

Causes skin irritation. May cause dermatitis. May cause cyanosis of the extremities.
【Eyes】

Causes eye irritation. May cause chemical conjunctivitis and corneal damage.
【Ingestion】

May cause gastrointestinal irritation with nausea, vomiting and diarrhea.
【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 ProtectionBack to Contents
【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】

A respiratory protection program that meets OSHA's 29 CFR 1910.134 and ANSI Z88.2 requirements or European Standard EN 149 must be followed whenever workplace conditions warrant a respirator's use.
【Exposure Effects】

Effects may be delayed.
【Exposure limit(s)】

NIOSH REL: C 0.5 ppm (3.3 mg/m3) [15-minute]
Fire Fighting MeasuresBack to Contents
【Flash Point】

78
【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. Will burn if involved in a fire. Use water spray to keep fire-exposed containers cool. Combustible Liquid. Vapors may be heavier than air. They can spread along the ground and collect in low or confined areas. Containers may explode when heated. Extinguishing media: Use water spray to cool fire-exposed containers. This material is lighter than water and insoluble in water. The fire could easily be spread by the use of water in an area where the water cannot be contained. In case of fire, use carbon dioxide, dry chemical powder or appropriate foam.
【Lower exp. limit】

.7
【Fire Potential】

HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames.
Accidental Release MeasuresBack to Contents
【Small spills/leaks】

Absorb spill with inert material, (e.g., dry sand or earth), then place into a chemical waste container. Avoid runoff into storm sewers and ditches which lead to waterways. Remove all sources of ignition. Use a spark-proof tool. Provide ventilation.
Stability and ReactivityBack to Contents
【Incompatibilities】

Oxidizing agents, reducing agents, strong acids, strong bases, alkali metals.
【Stability】

Stable at room temperature in closed containers under normal storage and handling conditions.
【Decomposition】

Carbon monoxide, oxides of sulfur, irritating and toxic fumes and gases, carbon dioxide, hydrogen sulfide.
【Combustion Products】

Fire will produce irritating, corrosive and/or toxic gases.
