Section 3 - Hazards Identification

EMERGENCY OVERVIEW

Appearance: orange powder.
Danger! Toxic if swallowed. Possible cancer hazard. May cause cancer based on animal data. Possible risks of irreversible effects. May cause methemoglobinemia. May cause cyanosis (bluish discoloration of skin due to deficient oxygenation of the blood).
Target Organs: Blood, kidneys, liver, lungs, respiratory system, skin.


Potential Health Effects
Eye: May cause eye irritation.
Skin: May cause skin irritation. May cause dermatitis. May be harmful if absorbed through the skin.
Ingestion: May cause irritation of the digestive tract. May form methemoglobin which in sufficient concentration causes cyanosis (bluish discoloration of skin due to deficient oxygenation of the blood). Toxic if swallowed.
Inhalation: May cause respiratory tract irritation. May be harmful if inhaled.
Chronic: Possible cancer hazard based on tests with laboratory animals. Prolonged or repeated skin contact may cause dermatitis. May cause methemoglobinemia, which is characterized by chocolate-brown colored blood, headache, weakness, dizziness, breath shortness, cyanosis (bluish skin due to deficient oxygenation of blood), rapid heart rate, unconsciousness and possible death. Chronic exposure may cause liver damage. Chronic exposure may cause blood effects. Possible risk of irreversible 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.
Skin: Get medical aid. Immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes.
Ingestion: POISON material. If swallowed, get medical aid immediately. Only induce vomiting if directed to do so by medical personnel. Never give anything by mouth to an unconscious person.
Inhalation: Get medical aid immediately. Remove from exposure and move to fresh air immediately. If breathing is difficult, give oxygen. Do not use mouth-to-mouth resuscitation if victim ingested or inhaled the substance; induce artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device.
Notes to Physician: Treat symptomatically and supportively.

Section 5 - Fire Fighting Measures
