SECTION 3: Hazards Identification

Emergency Overview:

Toxic by inhalation and if swallowed. Irritating to skin, eyes and
respiratory tract.

Primary Routes of Exposure:

Contact with skin and eyes. Inhalation of dust.

Eye
Contact:

Causes irritation and serious eye damage. Effects may not immediately
appear.

Skin
Contact:

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.
Apply calcium gluconate jelly or water soluble calcium salts as
antidote. Seek medical assistance.

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

not
applicable

Autoignition Temperature:

none

Explosion Limits:

none

Extinguishing Medium:

None. Material is non-flammable.

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 corrosive fumes of
hydrofluoric acid.

Unusual Fire or Explosion Hazards:

No
unusual fire or explosion hazards.

SECTION 6: Accidental Release Measures

Spill and Leak Procedures:

Small spills can be mixed with powdered sodium bicarbonate, lime, or
calcium carbonate and swept up. Avoid raising dust. Spillage in areas
not adequately ventilated may require an evacuation of area. Emergency
response teams will require self-contained breathing apparatus.

SECTION 7: Handling and Storage

Handling and Storage:

Store solid in a tightly sealed container away from moisture. Handle
under a dry atmosphere of air or nitrogen. Prolonged exposure to the
atmosphere may degrade the product.

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:

solid may form a toxic fine dust. If possible, handle the solid in an
efficient fume hood.

Respirator:

If
in form of fine dust and 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.
