Reports of Carcinogenicity:NTP:NO IARC:NO OSHA:NO
Health Hazards Acute and Chronic:ACUTE: SEVERE POISON AND CORROSIVE!
BURNS EYES/SKIN/RESPIRATORY SYSTEM. WILL DEPLETE CALCIUM IN BONES
AND TEETH. CAN AFFECT KIDNEY FUNCTION. EYE CONTACT CAUSES CORNEAL
BURNS/CONJUNCTIVITIS. CAUSES LUN G INFLAMMATION AND PULMONARY
EDEMA. CHRONIC: BONE AND JOINT CHANGES (FLUOROSIS), HYPOCALCEMIA.
Explanation of Carcinogenicity:HYDROFLUORIC ACID IS NOT LISTED BY IARC,
NTP, OR OSHA AS A CARCINOGEN.
Effects of Overexposure:INFLAMMATION OF THE NOSE, THROAT, UPPER
RESPIRATORY TRACT, EYES, SKIN AND MUCOUS MEMBRANES. VERY CORROSIVE
AND CAN CAUSE SEVERE BURNS AND DAMAGE. SLOW TO HEAL BURNS, FLUORIDE
POISONING AND CALCIUM DEP LETION POISONING ARE SYMPTOMS ARE
EXPOSURE.
Medical Cond Aggravated by Exposure:PERSONS WITH A HISTORY OF AILMENTS
OR WITH A PRE-EXISTING DISEASE INVOLVING THE EYES, SKIN, KIDNEY, OR
RESPIRATORY TRACT MAY BE AT INCREASED RISK FROM EXPOSURE.

First Aid:INHALATION:REMOVE TO FRESH AIR. RESUSCITATE IF NOT BREATHING.
EYES:FLUSH WITH PLENTY OF WATER FOR 15 MINUTES HOLDING EYELIDS
OPEN. SKIN:REMOVE CONTAMINATED CLOTHING AND DRENCH WITH WATER FOR
20 MINUTE S. TREAT BURNED AREA WITH ICED 0.2% HYAMINE 1622 OR 0.13%
ZEPHIRAN CHLORIDE. GET IMMEDIATE MEDICAL ATTENTION. INGESTION:DO
NOT INDUCE VOMITING. GIVE MILK OR MILK OF MAGNESIA. SEEK MEDIAL
HELP ALL CASE

APPROPRIATE FOR SURROUNDINGS. DO NOT USE WATER ON HF (REACTS
VIOLENTLY)
Fire Fighting Procedures:WEAR FIRE FIGHTING PROTECTIVE EQUIPMENT AND A
FULL FACED SELF CONTAINED BREATHING APPARATUS. EVACUATE AREA. COOL
FIRE EXPOSED CONTAINERS WITH WATER SPRAY.
Unusual Fire/Explosion Hazard:COMBUSTION OR HEAT OF FIRE MAY PRODUCE
HAZARDOUS DECOMPOSITION PRODUCTS AND VAPORS.

Spill Release Procedures:SMALL SPILL: FLUSH WITH WATER AND NEUTRALIZE
WITH ALKALINE MATERIAL. SEWER NEUTRALIZED MATERIAL WITH EXCESS
WATER. LARGE SPILL: EVACUATE AND VENTILATE AREA. IF POSSIBLE, STOP
LEAK. DIKE TO RETAIN RUN OFF. NEUTRALIZE & PICK UP WITH ABSORBENT
MATERIAL.
Neutralizing Agent:SODA ASH, LIME OR OTHER SUITABLE ALKALINE MATERIAL.
