SECTION 3: Hazards Identification
Emergency Overview:	Pyrophoric material. Ignites spontaneously on contact with air. Harmful by inhalation, in contact with skin and if swallowed.
Primary Routes of Exposure:	skin, eyes, inhalation of fumes
Eye Contact:	Liquid causes severe thermal burns to eyes. Irritating fumes.
Skin Contact:	Liquid ignites. Hard to extinguish burning gel on the skin and clothing
Inhalation:	White fumes from burning liquid irritating to the tissues of the nose, mucous membranes, and respiratory tract.
Ingestion:	Ingestion of burning liquid is unlikely
Acute Health Effects:	Liquid 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.

SECTION 5: Fire Fighting Measures
Flash Point:	-1F°C
Autoignition Temperature:	Pyrophoric
Explosion Limits:	no data
Extinguishing Medium:	Vermiculite, sand, dry chemical. Use no water
Special Fire Fighting Procedures:	Fire fighters should be equipped with a NIOSH approved positive pressure self-contained breathing apparatus and full protective clothing.
Hazardous Combustion and Decomposion Products:	Highly flammable. If involved in a fire this material may irritating fumes of gallium oxide
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:	Store in a steel cylinder under dry argon or nitrogen away from other flammable materials. Transfer using metal, not plastic materials. Expect fire when disassembling used piping. Do not use flammable solvents to clean out piping.

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 loose fitting rubber or leather gloves.
Ventilation:	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, and rubber lab apron.
