Route of Entry:
Target Organs:
Inhalation:
Respiratory system; Skin; Eyes;
At room temperature, MDI vapors are minimal due to low vapor pressure. However, heating,
spraying, foaming, or otherwise mechanically dispersing (drumming, venting or pumping)
operations may generate vapor or aerosol concentrations sufficient to cause irritation or other
adverse effects. Excessive exposure may cause irritation of the eyes, upper respiratory tract and

Skin Contact:
Eye Contact:
lungs. Severe overexposure may lead to pulmonary edema. May cause respiratory sensitization
with asthma-like symptoms in susceptible individuals. MDI concentrations below the exposure
guidelines may cause allergic respiratory reactions in individuals already sensitized. Symptoms
may include coughing, dryness of throat, headache, nausea, difficult breathing and a feeling of
tightness in the chest. Effects may be delayed. Impaired lung function (decreased ventilator
capacity) has been associated with overexposure to isocyanates
Chronic: As a result of previous repeated overexposures or a single large dose, certain individuals
develop isocyanate sensitization (chemical asthma) or tissue injury in the upper respiratory tract.
Animal tests indicate skin contact alone may also lead to allergic respiratory reaction. These
effects may be permanent. Any person developing asthmatic reaction or other sensitization should
be removed from further exposure
Product is a skin sensitizer. Causes irritation with symptoms of reddening, itching and swelling.
Prolonged or repeated exposure can cause skin irritation, reddening, dermatitis, and in some
individuals, sensitization. Skin contact may result in allergic skin reactions or respiratory
sensitization, but is not expected to result in absorption of amounts sufficient to cause other
adverse effects. May stain skin. Cured material is difficult to remove.
As a liquid, vapor, aerosol or dust, may cause irritation, inflammation, and/or damage to sensitive
eye tissue. Symptoms include reddening, tearing, stinging and swelling. May cause corneal injury.
Prolonged contact may cause conjunctivitis.
Ingestion: Single dose oral toxicity is considered to be extremely low. Can result in irritation and corrosive
action in the mouth, stomach tissue and digestive tract. Symptoms can include nausea, vomiting,
sore throat, abdominal pain and diarrhea. Ingestion is not an applicable route of entry for intended
use.

4 FIRST AID MEASURES
Inhalation: Remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, oxygen should be
administered by qualified personnel. Call a physician or transport to a medical facility immediately.
Skin Contact:Wash off in flowing warm water or shower with soap. Remove and wash contaminated clothing and discard
contaminated shoes. For severe exposure, get under safety shower after removing clothing, then seek
medical attention. If redness, itching or a burning sensation develops or persists after the area is washed,
consult a physician.
Eye Contact: Flush with large amounts of water for 15 minutes. Materials containing MDI may react with the moisture in
the eye forming a thick material that is difficult to remove. Get immediate medical attention.
Ingestion: DO NOT INDUCE VOMITING. Give 1-2 cups of milk or water to drink. Never give anything by mouth to an
unconscious person. Seek medical attention.

Use dry chemical, foam, carbon dioxide, foam or water spray for large fires. The reaction between water and hot isocyanate
may be vigorous. If possible, contain fire run-off water.
Protective Equipment: Wear positive-pressure self-contained breathing apparatus with full face mask and full protective
clothing.
Unusual Hazards: At temperatures greater than 400 F, polymeric MDI can polymerize and decompose which will cause
pressure build-up in closed containers. Explosive rupture is possible. Water contamination will produce carbon dioxide. Do not
reseal contaminated containers as pressure buildup may rupture the containers. Downwind personnel must be evacuated.
Fire Degradation Products: Isocyanate vapor and mist, carbon dioxide, carbon monoxide, nitrogen oxides and traces of
hydrogen cyanide.
6 ACCIDENTAL RELEASE MEASURES
Spill: Evacuate and isolate spill area. Remove any ignition sources. With adequate ventilation and appropriate personal
protective equipment, cover the area with an inert absorbent material such as clay or vermiculite and transfer to metal waste
containers. Move container to a well ventilated area (outside), but do not seal the container with the isocyanate mixture.
Larger quantities of liquid may be transferred directly to drums for disposal. Decontaminate or discard all clean-up equipment.
NOTE: ISOCYANATES WILL REACT WITH WATER AND GENERATE CARBON DIOXIDE. THIS COULD RESULT IN THE
RUPTURE OF ANY CLOSED CONTAINERS.
Clean up: The area should then be flushed with a decontamination solution. The decontamination solution is a 5-10% mixture
of sodium carbonate and 0.5% liquid detergent in water solution or a 3-8% concentrated ammonium hydroxide and 0.5%
liquid detergent in water. Use 10 parts decontamination solution to 1 part spilled material. If the ammonium hydroxide solution
is used, ammonia will be evolved as a vapor. Use caution to avoid exposure to high concentrations of ammonia. Allow to
stand for 48 hours letting evolved carbon dioxide escape.
7 HANDLING AND STORAGE
Handling Precautions: Handling: Use personal protective equipment when transferring material to or from drums,
totes or other containers. The reaction of polyols and isocyanates generates heat. Contact of
the reacting materials with skin or eyes can cause irritiation and may be difficult to remove
from the affected areas. Do not smoke or use naked lights, open flames, space heaters, or
other ignition sources near pouring, frothing or spraying operations.
Special Emphasis for Spray Applications: Inspect the application area from the potential to
expose other persons or for overspray to drift onto buildings, vehicles or other property. When
spraying building exteriors, persons entering or exiting the building as well as those inside
could be exposed to polyisocyanates due to wind conditions, open windows or air intakes. Do
not begin application work until these potential problems have been corrected.
Storage Requirements: Storage: When stored between 15 and 30 C (60 and 85 F) in dry place in tightly sealed
containers, typical shelf life is 6 months or more from the date of manufacture. Consult
technical data sheet for shelf life requirements affecting performance quality. Should freezing
occur, the material must be thawed thoroughly and mixed until uniform. Opened containers
must be handled properly to prevent moisture pickup. Do not reseal if contamination is
suspected.
8 EXPOSURE CONTROLS/PERSONAL PROTECTION
Engineering Controls: MDI has a low vapor pressure at room temperature. Monitoring is required to determine
engineering controls. Uses requiring heating and/or spraying may require more agressive
engineering controls or PPE. Eyewash and safety showers should be available.
Personal Protective
Equipment:
HMIS PP, X | Consult your supervisor for special instructions
Personal protective equipment
Respiratory protection: Where risk assessment shows air-purifying respirators are appropriate
use a full-face particle respirator type N100 (US) or type P3 (EN 143) respirator cartridges as
a backup to engineering controls. If the respirator is the sole means of protection, use a full-
face supplied air respirator. Use respirators and components tested and approved under
appropriate government standards such as NIOSH (US) or CEN (EU).
Hand protection: Handle with gloves. Gloves must be inspected prior to use. Use proper glove
removal technique (without touching gloves outer surface) to avoid skin contact with this
