CONDITIONS RECOGNIZED AS BEING AGGRAVATED BY EXPOSURE TO THIS
PRODUCT. MAY CAUSE ALLERGIC RESPIRATORY REACTION IN PERSONS
SENSITVE TO A COMPONENT PRESENT AT <1.0 %.

First Aid:EYE CONTACT: FLUSH WITH WATER FOR 15 MINUTES. HOLD EYELIDS
APART TO RINSE ENTIRE EYE AND LIDS. GET MEDICAL ATTENTION. SKIN
CONTACT: REMOVE PRODUCT USING MECHANICAL METHODS BEFORE WASHING
WITH WATER. SEEK MEDICAL ATTENTION. INHALATION: MOVE TO FRESH AIR.
PROVIDE OXYGEN IF BREATHING IS DIFFICULT. GIVE ARTIFICIAL
RESPIRATION IF NOT BREATHING. GET MEDICAL ATTENTION. INGESTION:
NEVER GIVE AN UNCONSCIO US PERSON ANYTHING TO DRINK. IF
UNCONSCIOUS, TREAT FOR SHOCK. NOTIFY A PHYSICIAN OR NEAREST POISON
CONTROL CENTER. (CONTD. SEE "ECOLOGICAL")

Extinguishing Media:USE CARBON DIOXIDE, DRY CHEMICAL OR FOAM TYPE
EXTINGUISHING MEDIA.
Fire Fighting Procedures:AS IN ANY FIRE, PREVENT HUMAN EXPOSURE TO
FIRE, SMOKE, FUMES, OR PRODUCTS OF COMBUSTION. EVACUATE
NON-ESSENTIAL PERSONNEL FROM FIRE AREA. FIRE FIGHTERS SHOULD WEAR
FULL-FACE SELF-CONTAINED BREATHING A PPARATUS AND IMPERVIOUS
PROTECTIVE CLOTHING.
Unusual Fire/Explosion Hazard:VAPORS FROM COMBUSTION OF THE UNCURED
MATERIAL ARE TOXIC. THIS IS A PASTE LIKE MATERIAL THAT WILL BURN
WITH A LAZY SMOLDERING TYPE FLAME. COMBUSTIBLE VAPORS MAY
ACCUMULATE IN THE CONTAINER HEADSPACE O N FORMATION OF HYDROLYSIS
BY-PRODUCTS.

Spill Release Procedures:USE ADEQUATE VENTILATION. WEAR A
NIOSH-APPROVED RESPIRATOR WITH DUST, MIST AND FUME FILTER. WEAR
PROTECTIVE CLOTHING. ABSORB SPILL WITH SAND OR FULLER'S EARTH.
SWEEP UP AND PLACE IN APPROPRIATE CHEMIC AL WASTE CONTAINER. FLUSH
SPILL AREA WITH WATER. OBSERVE ALL LOCAL, STATE AND FEDERAL LAWS
REGARDING DISPOSAL, SPILL, CLEANUP, REMOVAL OR DISCHARGE.
Neutralizing Agent:NO DATA PROVIDED BY RESPONSIBLE PARTY.

Handling and Storage Precautions:STORE IN A COOL, DRY WELL-VENTILATED
AREA. EXERCISE DUE CAUTION TO PREVENT DAMAGE TO THE CONTAINER. KEEP
CONTAINERS CLOSED, EVEN WHEN EMPTY. OPEN CONTAINER WITH CARE.
COMBUSTIBLE VAPORS MAY BE PRESENT IN THE CONTAINER HEADSPACE AS A
RESULT OF THE FORMATION OF HYDROLYSIS BY PRODUCTS.
Other Precautions:EMPTY CONTAINERS MAY CONTAIN RESIDUAL MATERIAL. DO
NOT REUSE CONTAINERS UNLESS PROPERLY RECONDITIONED.

Respiratory Protection:IF ADEQUATE VENTILATION IS NOT AVAILABLE, WEAR A
NIOSH/MSHA APPROVED AIR-PURIFYING RESPIRATOR WITH ORGANIC VAPOR
FILTER CARTRIDGES.
Ventilation:USE GENERAL VENTILATION, LOCAL EXHAUST VENTILATION,
ENCLOSURE OR CONFINEMENT OF OPERATION, AND/OR PROCESS ISOLATION
AS NEEDED TO LIMIT EMPLOYEE EXPOSURE.
Protective Gloves:SUITABLE GLOVES TO MINIMIZE SKIN CONTACT.
Eye Protection:WEAR CHEMICAL SAFETY GLASSES, GOGGLES OR FACE SHIELD TO
AVOID EYE CONTACT.
Other Protective Equipment:SUITABLE LONG SLEEVED CLOTHING TO MINIMIZE
SKIN CONTACT.
Work Hygienic Practices:OPEN CONTAINERS OF FOOD AND BEVERAGES SHOULD BE
KEPT AWAY FROM AREAS WHERE PRODUCT USED OR STORED. EATING,
DRINKING, SMOKING, APPLICATION OF COSMETICS SHOULD BE PROHIBITED IN
AREAS PRODUCT BEING USED.
Supplemental Safety and Health
BEFORE EATING, WASH HANDS AND FACETO REMOVE RESIDUAL CONTAMINATION.
EXPOSURE LIMITS: NO EXPOSURE LIMIT HAS BEEN ESTABLISHED FOR THIS
MATERIAL. EXPOSURE LIMITS.METHYL ETHYL KETOXIME HAS BEEN ASSIGNED

EXPOSURE. NIOSH CRITERIA DOCUMENT ON CARBON BLACK RECOMMENDS THAT
ONLY CARBON BLACKS WITH POLYNUCLEAR HYDROCARBON (PAH) LEVELS
GREATER THAN 0.1% BE CONSIDERED SU SPECT CARCINOGENS. THE PAH
CONTENTS OF ALL CARBON BLACKS WHICH ARE USED AS INGREDIENTS IN
WACKER SILICONES CORPORATION PRODUCTS IS LESS THAN 0.1%.
