Section 3 - Hazards Identification

EMERGENCY OVERVIEW

Appearance: brown solid.
Warning! Harmful if absorbed through the skin. Harmful if swallowed. Causes eye irritation. Toxic to aquatic organisms, may cause long-term adverse effects in the aquatic environment. May cause skin and respiratory tract irritation. Hazardous polymerization may occur.
Target Organs: Blood, kidneys, central nervous system, liver, eyes.


Potential Health Effects
Eye: Causes eye irritation.
Skin: May cause skin irritation. Toxic in contact with skin. May be metabolized to cyanide which in turn acts by inhibiting cytochrome oxidase impairing cellular respiration.
Ingestion: May cause irritation of the digestive tract. May cause nausea and vomiting. Metabolism may release cyanide, which may result in headache, dizziness, weakness, collapse, unconsciousness and possible death. Toxic if swallowed.
Inhalation: May cause respiratory tract irritation. Toxic if inhaled.
Chronic: May cause liver and kidney damage. Chronic exposure may cause blood effects. Exposure to high concentrations may cause central nervous system depression. Exposure to small amounts of cyanide compounds over long periods of time is reported to cause loss of appetite, headache, weakness, nausea, dizziness, and symptoms of irritation of the upper respiratory tract and eyes.

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 imme diately.
Skin: Get medical aid immediately. 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


General Information: As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear.
