**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Causes burns. Irritating to respiratory system.
Potential Health Effects
Eye:
Causes eye burns. May cause chemical conjunctivitis and corneal
damage.
Skin:
Causes skin burns.
Ingestion:
Causes gastrointestinal tract burns.
Inhalation:
Causes chemical burns to the respiratory tract.
Chronic:
Chronic inhalation and ingestion may cause effects similar to those
of acute inhalation and ingestion. Chronic inhalation may cause lung
damage, bronchitis, and silicosis. May decrease blood clotting.
**** SECTION 4 - FIRST AID MEASURES ****
Eyes:
In case of contact, immediately flush eyes with plenty of water for
at least 15 minutes. Get medical aid immediately.
Skin:
In case of contact, immediately flush skin with plenty of water for
at least 15 minutes while removing contaminated clothing and shoes.
Get medical aid immediately. Wash clothing before reuse.
Ingestion:
If swallowed, do NOT induce vomiting. Get medical aid immediately.
If victim is fully conscious, give a cupful of water. Never give
anything by mouth to an unconscious person.
Inhalation:
If inhaled, remove to fresh air. If not breathing, give artificial
respiration. If breathing is difficult, give oxygen. Get medical aid.
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. Substance is noncombustible.
Extinguishing Media:
Substance is noncombustible; use agent most appropriate to
extinguish surrounding fire.
**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Vacuum or sweep up material and place into a suitable disposal
container. Clean up spills immediately, observing precautions in the
