Routes of Entry: Inhalation:YES Skin:NO Ingestion:NO
Reports of Carcinogenicity:NTP:NO IARC:NO OSHA:NO
Health Hazards Acute and Chronic:INHAL:MAY CAUSE RESP SENSIT IN
SUSCEPTIBLE INDIVIDUALS. AT ROOM TEMP, VAPS ARE MINIMAL DUE TO LOW
VAP PRESS. IF HEATED OR SPRAYED AS AN AEROSOL, EXCESS CONCS ARE
ATTAINABLE THAT COULD BE HAZ ON SINGLE EXPOSURE. EXCESS EXPOSURE
MAY CAUSE IRRIT OF THE EYES, UPPER RESP TRACT & LUNGS. EFTS MAY BE
DELAYED.(EFTS OF OVEREXP)
Explanation of Carcinogenicity:NOT RELEVANT
Effects of Overexposure:HLTH HAZ:DECREASE VENT CAPACITY HAS BEEN ASSOC
W/EXPOSURE TO SIMILAR ISOCYANATES; IT IS POSSIBLE THAT EXPOSURE TO
MDI MAY CAUSE IMPAIRMENT OF LUNG FUNCTION. ADDNLY, THIS PROD CNTNS
PETROLEUM DISTILLAT ES & INHAL OF CONC VAPS CAN LEAD TO HDCH &
NAUS. SKIN:MAY CAUSE ALLERGIC SKIN RXN IN SUSCEPTIBLE
INDIVIDUALS.(SUPP DATA)
Medical Cond Aggravated by Exposure:NONE SPECIFIED BY MANUFACTURER.

First Aid:EYE: FLUSH W/CLEAN, LUKE WARM WATER @ LOW PRESS FOR @ LST 15
MIN, OCCASNLY LIFTING EYELIDS. CONSULT MD IMMED. SKIN:REMOVE CONTAM
CLTHG. WASH EXPOSED AREA W/WARM SOAPY WATER THORO. CONTAM CLTHG
SHOULD BE PROPERLY LAUNDERED BEFORE REUSING. INHAL:REMOVE VICTIM
FROM AREA OF EXPOSURE TO SAFE AREA. IF NOT BRTHG, GIVE
MOUTH-TO-MOUTH RESUSCITATION. IF BRTHG IS DFCLT, GIVE O*2. CONSULT
MD IMMED. (ING 6)

Flash Point:>180F,>82C
Extinguishing Media:DRY CHEM EXTING SUCH AS MONOAMMONIUM PHOSPHATE,
POTASSIUM SULFATE, POTASSIUM CHLORIDE. ADDNLY, CO*2, HIGH (ING 21)
Fire Fighting Procedures:IF WATER IS USED, USE LARGE AMOUNTS AS THE
REACTION BETWEEN HOT ISOCYANATES AND WATER CAN BE VIGOROUS. USE
NIOSH/MSHA APPROVED SCBA AND FULL PROT EQUIP .
Unusual Fire/Explosion Hazard:WATER CONTAMINATION WILL PRODUCE CARBON
DIOXIDE. DO NOT RE-SEAL CONTAMINATED CONTAINERS AS PRESSURE BUILDUP
MAY RUPTURE THEM. COMBUSTIBLE LIQUID.

Spill Release Procedures:MINOR SPILLS: CNTN SPILLED MATL & THEN COVER
W/LOOSE, ABSORBANT MATL SUCH AS OILDRY, VERMICULITE, SAWDUST OR
FULLER'S EARTH. SHOVEL WASTE MATL INTO PROPER WASTE CNTNRS. DO NOT
MAKE PRESSURE TIGHT. TRA NSPORT TO WELL-VENT AREA & TREAT W/A (ING
9)
Neutralizing Agent:NONE SPECIFIED BY MANUFACTURER.

Handling and Storage Precautions:IF CONTAM OF THE MDI IS SUSPECTED. DO
NOT RE-SEAL CONTAINER BECAUSE OF POSSIBLE RUPTURE DUE TO PRESSURE
BUILDUP.
Other Precautions:ALWAYS VENT CONTAINER WHEN OPENING TO RELIEVE ANY
PRESSURE BUILDUP.

Respiratory Protection:THIS PROD HAS DEMONSTRATED NO OBSERVABLE EFTS AT
ROOM TEMPS, HOWEVER, ATMOSPHERIC LEVELS SHOULD BE MAINTAINED. IN
ADDN, IN ANY SPRAY APPLICATION/SITUATION WHRE AIRBORNE PARTICULATES
OR AEROSOL ARE GEN ERATED, A NIOSH/MSHA APPRVD (ING 17)
Ventilation:NATURAL/MECH. LOC EXHAUST WILL KEEP THE TLV BELOW MINIMUM
IN MOST CASES. SPILLS/OTHER EMERGENCIES MAY REQUIRE (ING 18)
Protective Gloves:NATURAL RUBBER OR POLYVINYL ALCOHOL.
Eye Protection:ANSI APPRVD LIQUID CHEM GOG & FSHLD.
Other Protective Equipment:IF CREAMS ARE USED, KEEP THE AREA COVERED BY
CREAM TO A MINIMUM. SFTY SHOWERS & EYE STATIONS SHOULD BE PROVIDED
(ING 19)
Work Hygienic Practices:ALL EMPLOYEES SHOULD BE PROPERLY TRAINED.
Supplemental Safety and Health
EFTS OF OVEREXP: PRLNGD/RPTD CNTCT MAY CAUSE SKIN IRRIT. MAY STAIN
SKIN. INGEST: THIS IS NOT CONSIDERED A COMMON OCCUP ROUTE OF
EXPOSURE, HOWEVER, PETROLEUM DISTILLATES ARE CONSIDERED HARMFUL IF
SWALL OWED. ADDNLY, INGEST MAY LEAD TO VOMIT & THE ASPIR OF
DISTILLATE INTO LUNGS CAN CAUSE PULMONARY EDEMA.
