SECTION 3: Hazards Identification
Emergency Overview:	Pyrophoric material. Ignites spontaneously on contact with air causing thermal burns. Burning solid/liquid clings to clothing and skin.
Primary Routes of Exposure:	skin, eyes, inhalation of fumes
Eye Contact:	Dust causes severe thermal burns to eyes. Irritating fumes.
Skin Contact:	Solid ignites. Hard to extinguish burning gel on the skin and clothing
Inhalation:	White fumes from burning solid irritating to the tissues of the nose, mucous membranes, and respiratory tract.
Ingestion:	Ingestion of burning solid is unlikely
Acute Health Effects:	Solid is pyrophoric and bursts into flame, causing severe thermal burns. Dense white smoke is irritating to eyes, and respiratory system.
Chronic Health Effects:	No information available on long-term chronic effects.
NTP:	No
IARC:	No
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.

Unusual Fire or Explosion Hazards:	Pyrophoric material. Material may ignite spontaneously on contact with air.

SECTION 6: Accidental Release Measures
Spill and Leak Procedures:	The material will ignite spontaneously in air. Burning material may release toxic fumes. Leave the area unless fitted with a self-contained breathing apparatus. Smother fire with dry powder. Do not use water.

SECTION 7: Handling and Storage
Handling and Storage:	Handle and store the material under an inert atmosphere of nitrogen or argon. Prepare for the possibility of fire. Keep away from heat.

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. Consult with glove manufacturer to determine the proper type of glove.
Ventilation:	Material may form a fine dust. If possible, handle the 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, lab apron and suitable gloves.
