=====================  Hazards Identification  =====================

LD50 LC50 Mixture:ORAL LD50 (RATS): 4130-6170 MG/KG
Routes of Entry: Inhalation:YES  Skin:YES  Ingestion:YES
Reports of Carcinogenicity:NTP:YES    IARC:YES	  OSHA:NO
Health Hazards Acute and Chronic:INHALATION MAY CAUSE IRRITATION OF
    MUCOUS MEMBRANES IN RESPIRATORY TRACT. SKIN CONTACT MAY CAUSE
    IRRITATION. EYE CONTACT MAY CAUDE SEVERE IRRITATION,
    CONJUNCTIVITIS. INGESTION MAY RESULT IN IRRITATION	AND CORROSIVE
    ACTION IN THE MOUTH, STOMACH TISSUE AND DIGESTIVE TRACT.
Explanation of Carcinogenicity:NTP LISTS TDI AS "SUBSTANCE REASONABLY
    ANTICIPATED TO BE A CARCINOGEN". IARC LISTS TDI IN GROUP 2B.
Effects of Overexposure:RUNNY NOSE, SORE THROAT, COUGHING, CHEST
    DISCOMFORT, SHORTNESS OF BREATH, REDUCED LUNG FUNCTION, FEVER,
    CHILLS, SKIN REDDENING/SWELLING/RASH/SCALING/BLISTERING, SKIN
    SENSITIZATION, EYE PAIN/TEARING/RE DDENING/SWELLING, CORNEAL
    DAMAGE, CONJUNCTIVITIS, CORROSIVE ACTION IN MOUTH/STOMACH
    TISSUR/DIGESTIVE TRACT, NAUSEA.
Medical Cond Aggravated by Exposure:PERSONS WITH PREEXISTING,
    NONSPECIFIC BRONCHIAL HYPERACTIVITY MAY EXPERIENCE ASTHMA ATTACKS.

=======================  First Aid Measures  =======================

Eyes: FLUSH WITH WATER FOR 15 MINUTES WHILE HOLDING EYELIDS
    OPEN. GET MEDICAL ATTENTION. SKIN: REMOVE CONTAMINATED CLOTHING.
    WASH WITH SOAP AND WATER. IF IRRITATION PERSIST, GET MEDICAL
    ATTENTION. INH ALATION: REMOVE TO FRESH AIR. RESTORE BREATHING. GET
    MEDICAL ATTENTION. INGESTION: DO NOT INDUCE VOMITING. GIVE 1-2 CUPS
    OF MILK OR WATER TO DRINK. NEVER GIVE ANYTHING BY MOUTH IF
    UNCONSCIOUS. GET MD.

=====================  Fire Fighting Measures  =====================

Flash Point Method:PMCC
Flash Point:260F,127C
Lower Limits:0.90 %
Upper Limits:9.50 %
Extinguishing Media:FOAM, CARBON DIOXIDE, DRY CHEMICAL, WATER
Fire Fighting Procedures:FIRE FIGHTERS SHOULD WEAR SELF CONTAINED
    BREATHING APPARATUS AND FULL PROTECTIVE GEAR. COOL TANKS AND
    CONTAINERS EXPOSED TO FIRE WITH WATER.
Unusual Fire/Explosion Hazard:REACTION BETWEEN WATER OR FOAM AND HOT
    TDI CAN BE VIGOROUS.

==================  Accidental Release Measures  ==================

Spill Release Procedures:EVACUATE ALL NON-ESSENTIAL PERSONNEL.
    VENTILATE IF INDOORS. ABSORB SPILL WITH SAWDUST OR OTHER ABSORBENT,
    PLACE IN SUITABLE UNSEALED CONTAINERS, TRANSPORT TO WELL-VENTILATED
    AREA. AND TREAT WITH NEUTR ALIZING SOLUTION. ALLOW TO STAND FOR
    48HOURS.
Neutralizing Agent:NEUTRALIZING SOLUTION: WATER (80%), NON-IONIC
    SURFACTANT TERGITOL TMN-10 (20%).

======================	Handling and Storage  ======================

Handling and Storage Precautions:STORE IN TIGHTLY CLOSED CONTAINERS TO
    PREVENT MOISTURE CONTAMINATION. DO NOT RESEAL IF CONTAMINATION IS
    SUSPECTED. PREVENT ALL CONTACT.
Other Precautions:DO NOT BREATHE THE VAPORS. WARNING PROPERTIES ARE NOT
    ADEQUATE TO PREVENT CHRONIC OVEREXPOSURE FORM INHALATION. THIS
    MATERIAL CAN PRODUCE ASTHMATIC SENSITIZATION UPON EITHER SINGLE
    INHALATION OR REPEA TED INHALATION EXPOSURES.

=============  Exposure Controls/Personal Protection  =============

Respiratory Protection:AN APPROVED POSITIVE PRESSURE AIR-SUPPLIED
    RESPIRATOR IS REQUIRED WHENEVER TDI CONCENTRATIONS ARE NOT KNOWN OR
    EXCEED THE TLVS. AN APPROVED AIR-SUPPLIED RESPIRATOR WITH FULL
    FACEPIECE MUST ALSO BE WOR N DURING SPRAY APPLICATIONS.
Ventilation:LOCAL EXHAUST SHOULD BE USED TO MAINTAIN LEVELS BELOW TLV
    WHENEVER TDI IS HANDLED, PROCESSED OR SPRAY-APPLIED.
Protective Gloves:BUTYL RUBBER, NITRILE RUBBER, PVA
Eye Protection:CHEMICAL GOGGLES, SAFETY GLASSES W/SIDES
Other Protective Equipment:CHEMICAL RESISTANT CLOTHING AS NECESSARY TO
    PREVENT SKIN CONTACT. AN EMERGENCY EYEWASH AND SHOWER SHOULD BE
    AVAILABLE.
Work Hygienic Practices:WASH HANDS THOROUGHLY WITH SOAP AND WATER
    BEFORE EATING, DRINKING, SMOKING OR USING TOILET FACILITIES.
Supplemental Safety and Health
CONTACT LENSES SHOULD NOT BE WORN. MEDICAL SUPERVISION OF ALL EMPLOYEES
    WHO HANDLE OR COME IN CONTACT WITH TDI IS RECOMMEENDED. THESE
    SHOULD INCLUED PREEMPLOYMENT AND PERIODIC MEDICAL EXAMINATIONS WIT
    H RESPIRATORY FUNCTION TESTS (FEV, FVC AS A MINIMUM). PERSONS WITH
    ASTHMATIC-TYPE CONDITIONS SHOULD BE EXCLUDED.
