       Ingestion, inhalation, and skin contact.

       Eyes:

       Causes moderate eye irritation

       Skin:

       Harmful if absorbed through the skin.

Section 4: First Aid Measures:

       Eyes:

       Flush eyes with plenty of water for 15 minutes. Get medical attention if irritation persists

       Skin:

       Wash with plenty of soap and water. Get medical attention if irritation persists

       Ingestion:

       Call a physician or Poison Control Center. Drink 1 or 2 glasses of water and induce vomiting by

       touching back of throat with finger. Do not induce vomiting or give anything by mouth to an

       unconscious person.

       Inhalation:

       Remove person to fresh air. If not breathing, give artificial respiration, preferably mouth to

       mouth. Get medical attention

       Note to Physician:

       Surface contact can produce conjunctivitis, pharyngitis and rhinitis. Ingestion causes abdominal

       pain, nausea and vomiting. Inhalation is more dangerous, inducing respiratory stimulation, then

       depression and possibly seizures. There is no specific antidote. Treatment is supportive.



Section 5: Fire Fighting Measures:

       Extinguishing Media:

       Carbon dioxide, dry chemical, foam or water

       Fire Fighting Instructions:

       As in any fire, wear self-contained breathing apparatus, pressure demand, MSHA/NIOSH

       approved (or equivalent), and full protective gear. Keep upwind. Isolate hazard area. Avoid

       inhalation of smoke and fumes. Use water or foam to reduce fumes. Do not touch spilled

       material. If possible, move containers from area. Extinguish only if flow can be stopped. Use

       flooding amounts of water as a fog. Cool containers with flooding amounts of water from as far a

       distance as possible. Avoid breathing vapors.

       Flammability Classification/Rating:

       NFPA/OSHA Class: IIIB

       NFPA Rating (Fire): 1



Section 6: Accidental Release Measures:

       General and Disposal: Use proper protective equipment to minimize personal exposure (see

       Section 8). Take all necessary action to prevent and to remedy the adverse effect of the spill.

       Ensure that the disposal is in compliance with all Federal, State/Provincial, and local regulations

       (see Section 13 for applicable RCRA number). Refer to Section 15 for applicable Reportable

       Quantity (RQ) and other regulatory requirements.

       Land Spill: Sweep or shovel spilled material into a tightly sealed container. Dispose of with

       chemical waste.
