Health Hazards Acute and Chronic:CONTAINS TOLUENE DIISOCYANATE (TDI)
VAPOR EXTREMELY IRRITATING MAY CAUSE ALLERGIC SKIN OR RESPIRATORY
REACTION CAUSES EYE IRRITATION CONTAMINATION OR PRESSURE HEAT MAY
RESULT IN DANGEROUS PRESSUR E. CHRONIC TOXICITY HAZARD CONTAINS
TDI WHICH MAY CAUSE RESPIRATORY SYSTEM DAMAGE. TDI CAUSED CANCER IN
LABORATORY ANIMAL TESTS. RISK DEPENDS ON DURATION AND LEVEL OF
EXPOSURE.
Effects of Overexposure:ACUTE ORAL (RAT) AND DERMAL (RABBIT) LD50
VALUES ARE ESTIMATED TO BE GREATER THAN 5,000 MG/KG AND GREATER
THAN 2,000 MG/KG RESPECTIVELY. THE 4-HOUR LC50 (RAT) VALUE IS
CALCULATED TO BE 2.9 MG/L. REPEA TED OR PROLONGED DERMAL
CONTACTWITH THIS MATERIAL MAY CAUSE ALLERGIC SKIN REACTIONS. DIRECT
CONTACT WITH THIS MATERIAL MAY CAUSE MODERATE EYE AND SKIN
IRRITATION. INHALATION OVEREXPOSURE MAY CAUSE IRR ITATION OF THE
RESPIRATORY TRACT AND EYES. INHALATIONS OVEREXPOSURE MAY CAUSE
ALLERGIC RESPIRATORY REACTION.

First Aid:DIRECT CONTACT WITH THIS MATERIAL MAY CAUSE MODERATE EYE AND
SKIN IRRITATION. IN CASE OF SKIN CONTACT. IMMEDIATELY WASH
AFFECTED AREAS WITH SOAP AND WATER. REMOVE CONTAMINATED CLOTHING
AND SHOES. DES TROY OR THOROUGHLY CLEAN SHOES BEFORE REUSE. DO NOT
REUSE CONTAMINATED CLOTHING WITHOUT LAUNDERING. IN CASE OF EYE
CONTACT, IMMEDIATELY IRRIGATE WITH PLENTY OF WATER FOR 15 MINUTES.
OBTAIN MEDICAL ATT ENTION IF IRRITATION PERSISTS. IF VAPOR OF
THIS MATERIAL IS INHALED, REMOVE FROM EXPOSURE. ADMINISTER OXYGEN
IF THERE IS DIFFICULTY IN BREATHING. GIVE ARTIFICIAL RESPIRATION IF
PERSON IS NOT BREATHI NG AND CONTINUE UNTIL NORMAL BREATHING.

Flash Point Method:TCC
Flash Point:>93.3C, 200.F
Extinguishing Media:USE CARBON DIOXIDE, DRY CHEMICAL, WATER SPRAY OR
ALCOHOL FOAM TO EXTINGUISH FIRES. USE WATER TO KEEP CONTAINERS
COOL.

Spill Release Procedures:WHERE EXPOSURE LEVEL IS NOT KNOWN, WEAR NIOSH
APPROVED, POSITIVE PRESSURE, SELF CONTAINED RESPIRATOR. WHERE
EXPOSURE LEVEL IS KNOWN. WEAR NIOSH APPROVED RESPIRATOR SUITABLE
FOR LEVEL OF EXPOSURE. IN A DDITION TO THE PROTECTIVE
CLOTHING/EQUIPMENT IN SECTION 8 (EXPOSURE CONTROLS/PERSONAL
PROTECTION), WEAR IMPERVIOUS BOOTS. COVER SPILLS WITH SOME INERT
ABSORBENT MATERIALS.

Handling and Storage Precautions:AVOID BREATHING VAPOR. AVOID CONTACT
WITH EYES, SKIN, AND CLOTHING. KEEP CONTAINER CLOSED. USE WITH
ADEQUATE VENTILATION. DO NOT ALLOW OR OTHER LIQUIDS TO GET INTO
CONTAINER. DO NOT HEAT CONTENTS IN C LOSED CONTAINERS.

Respiratory Protection:WHERE EXPOSURES EXCEED THE PEL, USE RESPIRATOR
APPROVED BY NIOSH FOR THE MATERIALS
Ventilation:WHERE THIS MATERIAL IS NOT USED IN A CLOSED SYSTEM, GOOD
ENCLOSURE AND EXHAUST VENTILATION SHOULD BE PROVIDED TO CONTROL
EXPOSURES
Eye Protection:CHEMICAL SPLASH PROOF GOGGLES OR FACE SHIELDS
Other Protective Equipment:PROTECTIVE CLOTHING SUCH AS IMPERVIOUS
GLOVES, APRON, WORKPANTS, LONG SLEEVE WORK SHIRT, OR DISPOSABLE
COVERALLS ARE RECOMMENDED TO PREVENT SKIN CONTACT.
Work Hygienic Practices:EYEWASH EQUIPMENT AND SAFETY SHOWER SHOULD BE
PROVIDED IN AREAS OF POTENTIAL EXPOSURES.

APPLICABLE REGULATIONS.

Toxicological Information:ACUTE OVEREXPOSURES TO TOLUENE DILLSOCYANTE
VAPOR MAY CAUSE SEVERE RESPIRATORY IRRITATION. REPEATED
OVEREXPOSURES TO LOW LEVELS MAY CAUSE RESPIRATORY SENSITIZATION AND
ALLERGIC REACTION. RESPIRATORY S ENSITIZATION MANIFESTS ITSELF AS
SEVERE BREATHING DIFFICULTY SIMILAR TO ASTHMA. THIS REACT MAY OCCUR
6-24 HOURS AFTER EXPOSURE AND AT EXPOSURES LEVELS BELOW THE
ESTABLISHED PERMISSIBLE LIMITS. SKIN EX POSURE TO THE LIQUID MAY
CAUSE MODERATE IRRITATION AND ALLERGIC SKIN REACTION. IT IS ALSO AN
EYE IRRITANT. THE ORAL LD50 IS THE RATE IS 5.8-6.2 G/KG.
