SECTION 3: Hazards Identification
Emergency Overview:	Dust causes irritation of eyes and nasal cavity.
Primary Routes of Exposure:	Ingestion, inhalation.
Eye Contact:	Causes slight to mild irritation of the eyes.
Skin Contact:	May cause slight to mild irritation of the skin.
Inhalation:	Inhalation of fine dust is irritating to the nasal cavity, mucous membranes and respiratory tract.
Ingestion:	No specific information on the physiological effects of ingestion.
Acute Health Effects:	Dust may be irritating to eyes and respiratory tract.
Chronic Health Effects:	No information available on long-term exposure to this material.
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:	not applicable
Autoignition Temperature:	no data
Explosion Limits:	no data
Extinguishing Medium:	Dry chemical or Class D metal fire agent.
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.
Hazardous Combustion and Decomposion Products:	If involved in a fire, burning boron may produce mildly irritating fumes of boric acid.
Unusual Fire or Explosion Hazards:	Flammable solid. Dust may form explosive mixtures with air under some conditions.

SECTION 6: Accidental Release Measures
Spill and Leak Procedures:	In the case of a spill, the fine powder should be covered with sodium carbonate or dolomite in order to reduce the formation of airborne dust. Sweep up the mixture.

SECTION 7: Handling and Storage
Handling and Storage:	Store in a tightly sealed container in a cool dry place. Use good housekeeping practice to avoid accumulation of spilled dust and so avoid the resulting fire hazard.

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 is 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:	No additional protection required.
