EMERGENCY OVERVIEW
Harmful by inhalation, in contact with skin and if swallowed.
Limited evidence of a carcinogenic effect. Very toxic to aquatic organisms. Toxic : danger of serious damage to health by prolonged exposure through inhalation, contact with skin and if swallowed.The toxicological properties of this material have not been fully investigated.Hygroscopic (absorbs moisture from the air).Light sensitive.
Potential Health Effects
Eye:
May cause eye irritation.
Skin:
May cause skin irritation. Harmful if absorbed through the skin. If absorbed, may cause symptoms similar to those for ingestion.
Ingestion:
May cause gastrointestinal irritation with nausea, vomiting and diarrhea. The toxicological properties of this substance have not been fully investigated. Methemoglobinemia is characterized by dizziness, drowsiness, headache, shortness of breath, cyanosis (bluish discoloration of skin due to deficient oxygenation of the blood), rapid heart rate and chocolate-brown colored blood.
Overexposure may cause methemoglobinemia.
Inhalation:
May cause respiratory tract irritation. May cause effects similar to those described for ingestion. May cause pulmonary edema and severe respiratory disturbances. The toxicological properties of this substance have not been fully investigated.
Chronic:
Possible cancer hazard based on tests with laboratory animals.

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 immediately. Immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes.
Ingestion:
If victim is conscious and alert, give 2-4 cupfuls of milk or water.
Get medical aid immediately.
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:
Absorption of this product into the body may cause cyanosis (bluish discoloration of skin due to deficient oxygenation of the blood).
Moderate degrees of cyanosis need to be treated only by supportive measures: bed rest and oxygen inhalation. For methemoglobinemia, administer oxygen alone or with Methylene Blue depending on the methemoglobin concentration in the blood. Cleansing of the entire contaminated area of the body is of utmost importance.

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.
Extinguishing Media:
Use water spray, dry chemical, carbon dioxide, or chemical foam.
