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.
Causes burns.

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.

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.
