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: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.

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.

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
