OSHA:	No

SECTION 4: First Aid Measures
Eye Exposure:	Immediately flush the eyes with copious amounts of water for at least 10-15 minutes. A victim may need assistance in keeping their eye lids open. Get immediate medical attention.
Skin Exposure:	Wash the affected area with water. Remove contaminated clothes if necessary. Seek medical assistance if irritation persists.
Inhalation:	Remove the victim to fresh air. Closely monitor the victim for signs of respiratory problems, such as difficulty in breathing, coughing, wheezing, or pain. In such cases seek immediate medical assistance.
Ingestion:	Seek medical attention immediately. Keep the victim calm. Give the victim water (only if conscious). Induce vomiting only if directed by medical personnel.

SECTION 5: Fire Fighting Measures
Flash Point:	1°F
Autoignition Temperature:	pyrophoric
Explosion Limits:	pyrophoric
Extinguishing Medium:	carbon dioxide, dry powder or foam
Special Fire Fighting Procedures:	If this product is involved in a fire, fire fighters should be equipped with a NIOSH approved positive pressure self-contained breathing apparatus and full protective clothing.
Hazardous Combustion and Decomposion Products:	If involved in a fire this material may emit toxic organic fumes and vapors of phosphorus pentoxide.
Unusual Fire or Explosion Hazards:	Spontaneously flammable in air, especially in contact with organic matter such as paper or cloth.

SECTION 6: Accidental Release Measures
Spill and Leak Procedures:	The material may ignite spontaneously in air. Avoid static discharge. Burning material may release toxic fumes. In case of poor ventilation, leave the area unless fitted with a self-contained breathing apparatus. Small spills can be mixed with ground limestone, sodium bicarbonate or other suitable adsorbents, swept up and held in a closed metal can.

SECTION 7: Handling and Storage
Handling and Storage:	The material will degrade on exposure to air. Store and handle under an inert atmosphere of nitrogen or argon. Keep bottle tightly sealed and away from heat and direct sunlight.

SECTION 8: Exposure Controls and Personal Protection
Eye Protection:	Always wear approved safety glasses when handling a chemical substance in the laboratory.
Skin Protection:	Wear protective clothing and gloves.
Ventilation:	Material has a pungent odor. Always handle material in an efficient fume hood.
Respirator:	If ventilation is not available a respirator should be worn. The use of respirators requires a Respirator Protection Program to be in compliance with 29 CFR 1910.134.
Additional Protection:	Wear a full face shield, flame resistant lab apron and suitable gloves.
