Section 3 - HAZARDS IDENTIFICATION
EMERGENCY OVERVIEW
Harmful by inhalation and if swallowed.Cancer suspect agent.
Potential Health Effects
Eye:
May cause eye irritation.
Skin:
May be harmful if absorbed through the skin. May cause irritation and dermatitis.
Ingestion:
May cause gastrointestinal irritation with nausea, vomiting and diarrhea. May cause liver and kidney damage. May be harmful if swallowed. May form methemoglobin which in sufficient concentration causes cyanosis (bluish discoloration of skin due to deficient oxygenation of the blood).
Inhalation:
May cause respiratory tract irritation. May cause irritation of the mucous membranes.
Chronic:
Laboratory experiments have resulted in mutagenic effects.

Section 4 - FIRST AID MEASURES
Eyes: Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately.
Skin:
Get medical aid. Flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes.
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:
Remove from exposure and move to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid.
Notes to Physician:

Section 5 - FIRE FIGHTING MEASURES
General Information:
As in any fire, 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. Containers may explode in the heat of a fire.
Extinguishing Media:
Use water spray, dry chemical, carbon dioxide, or appropriate foam.
