First Aid:INGESTION: IF SWALLOWED, DO NOT INDUCE VOMITING. IF
CONSCIOUS, GIVE LARGE AMOUNTS OF WATER TO DRINK. FOLLOW WITH WHITE
OF EGGS BEATED WITH WATER. CALL PHYSICIAN IMMEDIATELY. NEVER GIVE
ANYTHING BY MOU TH TO AN UNCONSCIOUS PERSON. EYES: IMMEDIATELY

UPPER EYELIDS OCCASIONALLY.. GET PROMPT MEDICAL ATTENTION. SKIN:
FLOOD WITH WATER, TH EN WASH WITH VINEGAR. INHALATION: REMOVE TO
FRESH AIR. IF NOT BREATHING, GIVE ARTIFICIAL RESPIRATION. IF
BREATHING IS DIFFICULT, GIVE OXYGEN. GET MEDICAL ATTENTION.

Flash Point:NON-COMBUSTIBLE
Extinguishing Media:USE WATER ON FIRE INVOLVING THIS MATERIAL.
Fire Fighting Procedures:IN FIRE CONDITIONS WEAR A NIOSH-APPROVED
SELF-CONTAINED BREATHING APPARATUS AND FULL PROTECTIVE CLOTHING.
MUST INCLUDE COMPLETE EYE PROTECTION. FLOOD WITH WATER, USING CARE
NTO TO SPLATTER OR SPLASH T HIS MATERIAL. CONTACT WITH WATER
PRODUCES INTENSE HEAT AND HIGHLY IRRITATIING AND CORROSIVE MIST.
Unusual Fire/Explosion Hazard:NOT COMBUSTIBLE BUT SOLID FORM IN CONTACT
WITH MOISTURE OR WATER MAY GENERATE SUFFICIENT HEAT TO GENERATE
SUFFICIENT HEAT TO IGNITE COMBUSTIBLE MATERIALS. CONTACT WITH SOME
METALS CAN GENERATE HYDROGE N GAS.HOT OR MOLTEN MATERIAL WILL REACT
VIOLENTLY WITH WATER LIBERATING HEAT & CAUSING SPLASHING. A SEVER
EYE HAZARED.

Spill Release Procedures:CAREFULLY AND WEARING PROTECTIVE CLOTHING,
SWEEP UP AND PLACE IN A SUITABLE CONTAINER. FLUSH SPILL AREA WITH
WATER, RINSE WITH DILUTE ACID, PREFERABLY ACETIC, AND FINALLY WITH
WATER.

Handling and Storage Precautions:KEEP CONTAINER TIGHTLY CLOSED. STORE
IN A COOL, DRY PLACE; PROTECT AGAINST MOISTURE AND WATER. SEPARATE
FROM ACIDS, METALS, EXPLOSIVES, ORGANIC PEROXIDES AND EASILY
IGNITIBLE MATERIALS. AVOID CONTACT WITH SKIN, EYES AND CLOTHING.
KEEP CONTAINER TIGHTLY CLOSED WHEN NOT IN USE.
Other Precautions:DISPOSAL: WHILE MAKING SOLUTION ADD SLOWLY TO SURFACE
OF STIRRED LIQUID TO AVOID VIOLENT SPLATTERING. NEUTRALIZE WITH
SODIUM BISULFITE & FLUSH TO SEWER WITH COPIOUS AMOUNTS OF WATER.

Respiratory Protection:NONE REQUIRED IN NORMAL LABORATORY HANDLING. IF
DUSTY CONDITIONS PREVAIL, USE A HIGH EFFICIENCY PARTICULATE
RESPIRATOR.
Ventilation:LOCAL ECHAUST AND MECHANICAL (GENERAL): RECOMMENDED.
Protective Gloves:RUBBER.
Eye Protection:CHEMICAL SAFETY GOGGLES, OR FACE SHIELD WHERE
APPROPRIATE.
Other Protective Equipment:GOGGLES, LAB COAT, APRON, VENTLATION HOOD,
PROPER GLOVES, EYE WASH STATION.
