Section 3: HAZARD IDENTIFICATION
Appearance, form, odor: Liquid at STP with aromatic hydrocarbon type odor.
Route of Entry: Inhalation, Ingestion, Skin Absorption
Target Organ: Respiratory system, central nervous system, kidneys, liver, skin.
Inhalation: Harmful if inhaled. May affect the brain, nervous system, or respiratory system, causing
dizziness, headache, nausea or respiratory irritation.
Skin Contact: May cause moderate skin irritation.
Eye Contact: Corneal injury / eye damage.
Ingestion: None known.
Overexposure: Prolonged or overexposure has been associated with permanent branin and nervous
system damage. Misuse by deliberately concentrating and inhaling the contents may be
harmful or fatal. Possible birth defects hazard. Contains ingredients which may cause
birth defects based on animal data. May cause kidney damage. May cause liver damage.
SECTION 4: FIRST AID MEASURES
Inhalation: Remove patient to fresh air. If symptoms persist, get medical attention.
Skin Contact: Immediately remove contaminated clothing and excess contaminant. Flush skin with
water for 15 minutes. Wash thoroughly with soap and warm water. Consult a physician
if irritation develops.
Eye Contact: Flush eye with clean water for at least 15 minutes while gently holding eyelids open. Get
immediate medical attention.
Ingestion: Consult a physician immediately. DO NOT induce vomiting. If patient is conscious,
give milk or water. Never give anything by mouth to an unconscious person. If vomiting
occurs spontaneously, keep head below hips to prevent aspiration.
Note to Physician: EYES: stain for evidence of corneal injury. If corneal is burned, instill antibiotic steroid
preparation frequently. Workplace vapors have produced reversible corneal epithelial
edema impairing vision. SKIN: treat symptomatically as for contact dermatitis or
thermal burns. INGESTION: treat symptomatically. Inducing vomiting is
contraindicated because of irritating nature. RESPIRATORY: treat symptomatically.
Remove a sensitized individual from exposure to any isocyanate.
SECTION 5: FIRE-FIGHTING MEASURES
Extinguishing Media: CO2, Dry Chemical, Water Fog or All Purpose Foam
Flash Point (F): Method:
> 80 CCT
Explosive limits in air (percent): Lower: Upper:
--- 1% 7%
If exposed to a heat source, closed containers can build pressure leading to a sudden release. As in any fire, wear a
pressure demand MSHA / NIOSH approved self-contained breathing apparatus (SCBA), and full protective bunker

gear. For large fires, apply foam according to manufacturer's specifications. For small fires, utilize carbon dioxide
or dry chemical extinguishers. Keep containers cool by applying water spray.
SECTION 6: ACCIDENTAL RELEASE MEASURES
Spill control: Evacuate and ventilate area. Wear full protective equipment including respiratory equipment.
Dike spill to prevent entry into water system.
Containment: Dike with sawdust or other absorbent.
Cleanup: Wipe, scrape with non-sparking tools, or soak up in inert material such as dry sand or earth, and
put in an approved chemical waste container for disposal. Avoid and prevent runoff into storm
drains and ditches. Spilled materials should be contained and disposed of in accordance with local
and federal statutes.
SECTION 7: HANDLING AND STORAGE
Handling Precautions: Keep container closed when not in use.
Storage Requirements: Store tightly closed in a cool, dry place (below 120 F). Store away from potential
physical damage, ignition sources, and incompatible materials such as oxidizers and strong acids.
Based on flash point and vapor pressure, suitable storage should be provided in accordance with
SHA 1910.106, and Ontario OH & S Regulation 851 Section 22. Empty containers may contain
product residues, including flammable or explosive vapors. Do not cut, puncture, or weld on or
near container. All label warnings must be observed until the container has been commercially
cleaned or reconditioned. If the product is used near or above the flashpoint, an ignition hazard
may be present. Activities, uses, or operations which liberate vapors (such as mixing or free fall
of liquids) may also present an ignition hazard. Please ensure containers and other interconnected
equipment are properly bonded and grounded at all times.
SECTION 8: EXPOSURE CONTROLS AND PERSONAL PROTECTION
Engineering Controls: Explosion proof ventilation is required when spraying or applying in confined areas.
Eliminate ignition sources. Maintain vapor levels in air below established exposure limits.
Personal Protective
Equipment: Respiratory Protection
For locations where levels may exceed established exposure limits by no more than a
factor of ten, trained users should utilize proper NIOSH / MSHA (or equivalent)
approved air purifying respirators equipped with organic vapor cartridges with mist pre-
filters. For concentrations higher than the protection capabilities of air purifying
respirators, supplied air respiratory protection is required. All respiratory protection
should be used in accordance with 29 CFR, OSHA 1910.134 Respiratory Protection. In
events involving unknown concentrations, or an uncontrolled release, utilize a positive
pressure SCBA.
Eye Protection
Avoid contact with eyes. For liquid splash protection utilize chemical goggles, or a full
face splash shield. If fine aerosolized mist is present, utilize a full-face respirator.
Skin Protection
Wear appropriate chemical resistant clothing, rubber boots, and gloves made of
compatible materials.
