**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Toxic by inhalation and if swallowed. May cause cancer. Very toxic
to aquatic organisms, may cause long-term adverse effects in the
aquatic environment.Carcinogen.Hygroscopic (absorbs moisture from
the air).
Potential Health Effects
Eye:
Causes eye irritation.
Skin:
Causes skin irritation. May be fatal if absorbed through the skin.
Ingestion:
May be fatal if swallowed. Poison by ingestion. Causes
gastrointestinal irritation with nausea, vomiting and diarrhea.
Inhalation:
Causes respiratory tract irritation.
Chronic:
Prolonged or repeated skin contact may cause dermatitis. May cause
cancer in humans.
**** SECTION 4 - FIRST AID MEASURES ****
Eyes:
Flush eyes with plenty of water for at least 15 minutes,
occasionally lifting the upper and lower eyelids. Get medical aid
immediately.
Skin:

**** 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.
Extinguishing Media:
For small fires, use water spray, dry chemical, carbon dioxide or
chemical foam.
**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****
General Information: Use proper personal protective equipment as indicated
in Section 8.
