First Aid Measures

Ingestion
Never give anything by mouth to an unconscious person. 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. 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 Storage

Storage
Store in a tightly closed container. Store in a cool, dry area away from incompatible substances.
Handling
Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Do not get in eyes, on skin, or on clothing. Keep container tightly closed. Do not ingest or inhale. Use with adequate ventilation. Do not breathe dust or fumes.

Hazards Identification

Inhalation
Causes irritation of the mucous membrane and upper respiratory tract.
Skin
Causes skin irritation.
Eyes
Causes eye irritation. May cause chemical conjunctivitis.
Ingestion
May cause gastrointestinal irritation with nausea, vomiting and diarrhea.

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
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. Prolonged exposure can cause damage to the eyes, severe irritation or burns.

Fire Fighting Measures

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. To extinguish fire use water spray, dry chemical, carbon dioxide, or appropriate foam.

Accidental Release Measures

Small spills/leaks
Wash area with soap and water. Clean up spills immediately, using the appropriate protective equipment. Sweep up, then place into a suitable container for disposal. Provide ventilation.

Stability and Reactivity

Stability
Stable under normal temperatures and pressures.
Incompatibilities
Strong oxidizing agents, strong bases, acid chlorides, acid anhydrides.
Decomposition
Carbon monoxide, oxides of sulfur, carbon dioxide.
