**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Very toxic by inhalation. Irritating to eyes, respiratory system and
skin. Toxic in contact with skin and if swallowed. Toxic : danger of
serious damage to health by prolonged exposure if swallowed. Very
toxic to aquatic organisms, may cause long-term adverse effects in
the aquatic environment.Air sensitive.
Potential Health Effects
Eye:
Causes severe eye irritation.
Skin:
May cause skin irritation. Harmful if absorbed through the skin.
Ingestion:
Harmful if swallowed. May cause irritation of the digestive tract.
Human systemic effects include acute renal failure, acute tubular
necrosis, cough, diarrhea, dyspnea (labored breathing), headache,
hypermitility, nausea, vomiting, ulceration or bleeding from stomach.
Inhalation:
May cause respiratory tract irritation. May cause a delayed damaging
effect on the lung alveoli.
Chronic:
Effects may be delayed. Chronic ingestion may cause fetal effects.
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 immediately. Immediately flush skin with plenty of
water for at least 15 minutes while removing contaminated clothing
and shoes. Wash clothing before reuse.
Ingestion:
Do not induce vomiting. If victim is conscious and alert, give 2-4
cupfuls of milk or water. Never give anything by mouth to an
unconscious person. Get medical aid immediately.
Inhalation:
Remove from exposure and move to fresh air immediately. If breathing
is difficult, give oxygen. Get medical aid. Do NOT use mouth-to-mouth
resuscitation. If breathing has ceased apply artificial respiration
using oxygen and a suitable mechanical device such as a bag and a
mask.
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.
Extinguishing Media:
Use agent most appropriate to extinguish fire. In case of fire, use
carbon dioxide, dry chemical powder or appropriate foam.
**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Clean up spills immediately, observing precautions in the Protective
Equipment section. Avoid generating dusty conditions. Provide
ventilation. Place under an inert atmosphere. Cover with dry earth,
dry sand, or other non-combustible material followed with plastic
sheet to minimize spreading and contact with water.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Use only in a well-ventilated area.
Minimize dust generation and accumulation. Avoid contact with eyes,
skin, and clothing. Do not ingest or inhale. Handle under an inert
atmosphere. Store protected from air.
Storage:
Store in a tightly closed container. Store in a cool, dry,
well-ventilated area away from incompatible substances. Do not expose
to air. Store under an inert atmosphere.
**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
Engineering Controls:
Facilities storing or utilizing this material should be equipped
with an eyewash facility and a safety shower. Use adequate
ventilation to keep airborne concentrations low.
