**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Causes burns.
Potential Health Effects
Eye:
May cause irreversible eye injury. Contact with liquid is
corrosive to the eyes and causes severe burns.
Skin:
Contact with liquid is corrosive and causes severe burns and
ulceration.
Ingestion:
Causes severe pain, nausea, vomiting, diarrhea, and shock. May cause
hemorrhaging of the digestive tract. May cause corrosion and
permanent tissue destruction of the esophagus and digestive tract.
Inhalation:
Irritation may lead to chemical pneumonitis and pulmonary edema.
Causes severe irritation of upper respiratory tract with coughing,
burns, breathing difficulty, and possible coma.
Chronic:
Prolonged inhalation may cause respiratory tract inflammation and
lung damage.
**** 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. Powerful reducing agent. Decomposes at high
temperatures into H3PO4, phosphoric acid, and spontaneously flammable
PH3, phosphine.
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.
Spills/Leaks:
Cover with sand, dry lime or soda ash and place in a closed
container for disposal. Provide ventilation.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Use with adequate ventilation. Do not get in eyes,
on skin, or on clothing. Do not ingest or inhale.
Storage:
Store in a tightly closed container. Store in a cool, dry,
well-ventilated area away from incompatible substances. Store away
from alkalies. Separate from oxidizing materials.
**** 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.
Exposure Limits
