SECTION 3: Hazards Identification
Emergency Overview:	Flammable liquid. Irritating to skin eyes and mucous membranes. Boron affects the central nervous system. Boron poisoning causes depression of circulation, vomiting, diarrhea, shock, and coma.
Primary Routes of Exposure:	Ingestion, inhalation, skin and eyes.
Eye Contact:	May cause severe burns to the eyes.
Skin Contact:	Harmful in contact with skin. May be fatal if absorbed through the skin.
Inhalation:	Irritating to nose, mucous membranes, and respiratory tract. Causes bad taste in mouth, headache and nausea.
Ingestion:	May be toxic by ingestion. High doses may cause boron poisoning: convulsions, cyanosis, coma and death.
Acute Health Effects:	Irritating to eyes, skin and respiratory tract. Sore throat, and twitching of facial muscles may occur. High doses may cause convulsions, cyanosis, coma, and death.
Chronic Health Effects:	Repeated ingestion of some boron compounds may cause dryness of mucous membranes, anorexia, vomiting, mild diarrhea, skin rash, and low blood cell count. Kidney damage may occur.
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:	37°F
Autoignition Temperature:	206°C
Explosion Limits:	2.2-19.7%
Extinguishing Medium:	carbon dioxide, dry chemical
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:	Flammable. If involved in a fire this material may release toxic fumes and with water, explosive hydrogen gas.
Unusual Fire or Explosion Hazards:	Reacts violently with water to release explosive hydrogen gas.

SECTION 6: Accidental Release Measures
Spill and Leak Procedures:	Remove all ignition sources. Small spills can be mixed with vermiculite, sodium carbonate or other suitable non combustible adsorbent and swept up.

SECTION 7: Handling and Storage
Handling and Storage:	Handle and store the material under an inert atmosphere of nitrogen or argon. Store cold. Material may decompose if exposed to moisture or heated to >75 �C releasing flammable toxic diborane gas and cause bursting of containers.

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:	It is essential to 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:	No additional protection required.
