1
125 A
SKIN: Contact may cause irritation.
INGESTION: Not a likely route of exposure. Relatively non-toxic
INHALATION: Irritation of the nose, throat, and lungs may result from exposure to vapors or mist. Severe
overexposure may cause pulmonary edema. Can cause asthma like symptoms. May aggravate existing
conditions.
CHRONIC (CANCER) INFORMATION: Not classified as carcinogenic.
LONG TERM TOXIC EFFECTS: Skin and respiratory sensitization may result.
_____________________________________________________________________________
4. FIRST AID MEASURES
_____________________________________________________________________________
First Aid:
INHALATION: Remove to fresh air.
SKIN CONTACT: Wash thoroughly. Consult medical personnel if irritation develops.
EYE CONTACT: Irrigate eyes with running water for at least 15 minutes. Get medical attention.
INGESTION: None applicable but consult a physician.
NOTE TO PHYSICIAN:............................. Eyes. Stain for evidence of corneal injury. If cornea is
burned, instill antibiotic steroid preparation frequently.
Workplace vapors have produced reversible corneal
epithelial edema impairing vision.
Skin. This compound is a known skin sensitizer. Treat
symptomatically as for contact dermatitis or thermal
burns. If burned, treat as thermal burn.
Ingestion. Treat symptomatically. There is no specific
antidote. Inducing vomiting is contraindicated because
of the irritating nature of this compound.
Respiratory. This compound is a known pulmonary
sensitizer. Treatment is essentially symptomatic. An
individual having a skin or pulmonary sensitization
reaction to this material should be removed from
exposure to any Isocyanate.

5. FIRE FIGHTING MEASURES
_____________________________________________________________________________
FLASH POINT.................................................. .. 390 des. F (198.8 deg. C) Pensky-Martens Closed Cup
(ASTM D-93)
EXTINGUISHING MEDIA................................. .. Dry Chemical; Carbon Dioxide; Foam; Water spray for
large fires.
SPECIAL FIRE FIGHTING PROCEDURES:.... .. Full emergency equipment with self-contained breathing
apparatus and full protective clothing should be worn by
firefighters. During a fire, MDI vapors and other
irritation, highly toxic gases may be generated by
thermal decomposition or combustion. (See Section
VIII). At temperatures greater than 400 deg. F (204 deg.
C), polymeric MDI can polymerize and decompose
which can cause pressure build-up in closed containers.
Explosive rupture is possible. Therefore, use cold water
to cool fire-exposed containers.
_____________________________________________________________________________
6. ACCIDENTAL RELEASE MEASURES
_____________________________________________________________________________
Safeguards (Personnel)
NOTE: Review FIRE FIGHTING MEASURES and HANDLING (PERSONNEL) sections before
proceeding with clean-up. Use appropriate PERSONAL PROTECTIVE EQUIPMENT during clean-up.

____________________________________________________________________________________
7. HANDLING AND STORAGE
STORAGE TEMPERATURE (MIN/ MAX):........64 deg.F (18 deg.C) 86 deg. F (30 deg. C)
SHELF LIFE:.............................................Six months
SPECIAL SENSITIVITY...............................If container is exposed to high heat, 400 deg. F (204
deg. C), it can be pressurized and possibly rupture. MDI
reacts slowly with water to form carbon dioxide gas which
can cause sealed containers to expand and possibly
rupture.
HANDLING/ STORAGE PRECAUTION: ......... Store in tightly closed containers to prevent moisture
contamination. Do not reseal if contamination is suspected.
Avoid contact with skin and eyes. Do not breathe aerosols
or vapors. Warning properties (irritation of the eyes, nose
and throat or odor) are not adequate to prevent chronic
overexposure from inhalation. This material can produce
asthmatic sensitization upon either single inhalation
exposure to a relatively high concentration or upon
repeated inhalation exposures to lower concentrations.
Exposure to vapors of heated MDI can be extremely
dangerous. Employee education and training in the safe
handling of this compound are required under the OSHA
Hazard Communication Standard.
_________________________________________________________________________________
8. EXPOSURE CONTROLS/ PERSONAL PROTECTION
_________________________________________________________________________________
EYE PROTECTION REQUIREMENTS: ... Chemical tight goggles full-face shield if splashing is
....
possible.
SKIN PROTECTION REQUIREMENTS: Gloves determined to be impervious under the
.. ...
conditions of use. Depending on conditions of use,
additional protection may be required such as apron,
arm covers, or full body suit. Wash contaminated
clothing before rewearing.
RESPIRATOR REQUIREMENTS:............ ... Because of the low vapor pressure, ventilation is usually
sufficient to keep vapors below the TLV at room
temperatures. Exceptions are when the material is
sprayed or heated. If airborne concentrations exceed or
are expected to exceed the TLV, use MSHA/NIOSH
approved positive pressure supplied air respirator with a
full-face piece, or an air-supplied hood. For
emergencies, use a positive pressure self-contained
breathing apparatus. Air purifying (cartridge type)
respirators are not approved for protection against
Isocyanates.
VENTILATION REQUIREMENTS:............ ... If needed, use local exhaust ventilation to keep airborne
concentrations below the TLV. Follow guidelines in the
ACFGIH publication "Industrial Ventilation." Exhaust air
may need to be cleaned by scrubbers or filters to reduce
environmental contamination.
MONITORING:.......................................... ... Isocyanate exposure levels must be monitored.
Monitoring of airborne Isocyanates in the breathing zone
of individuals should become part of the overall
employee exposure characterization program. NIOSH,
and OSHA have developed monitoring techniques.
3
125 A
MEDICAL SURVEILLANCE:.................... ... Medical supervision of all employees who handle or
.
come in contact with Isocyanates is recommended.
These should include pre-employment and periodic
medical examinations with pulmonary function tests
(FEV, FVC as a minimum). Persons with asthmatic-type
conditions, chronic bronchitis, other chronic respiratory
diseases or recurrent skin eczema or sensitization
should be excluded from working with Isocyanates.
Once a person is diagnosed as sensitized to an
Isocyanate, no further exposure can be permitted.
ADDITIONAL PROTECTIVE MEASURES: ... Safety showers and eyewash stations should be
available. Educate and train employees in safe use of
product. Follow all label instructions.

HUMAN EFFECTS AND SYMPTOMS OF OVEREXPOSURE:
ACUTE INHALATION:...................................... MDI vapors or mist at concentrations above the
TLV can irritate (burning sensation) the mucous
membranes in the respiratory tract (nose, throat, lungs)
causing runny nose, sore throat, coughing, chest
discomfort, shortness of breath and reduced lung
function (breathing obstruction). Persons with a pre-
existing, nonspecific bronchial hyperactivity can respond
to concentrations below the TLV with similar systems as
well as asthma attack. Exposure well above the TLV
may lead to bronchitis, bronchial spasm and pulmonary
edema (fluid in lungs). These effects are usually
reversible. Chemical or hypersensitive pneumonitis, with
flu-like symptoms (e.g., fever, chills) has also been
reported. These systems can be delayed up to several
hours after exposure.
CHRONIC INHALATION:................................. As a result of previous repeated overexposures or a
single large dose, certain individuals develop Isocyanate
sensitization (chemical asthma), which will cause them
to react to a later exposure to Isocyanate at levels well
below the TLV. These symptoms, which can include
chest tightness, wheezing, cough, shortness of breath or
asthma attack, could be immediate or delayed (up to
several hours after exposure). Similar to many non-
specific asthmatic responses, there are reports that once
sensitized, an individual can experience these symptoms
upon exposure to dust, cold air or other irritants. This
increased lung sensitivity can persist for weeks and in
severe cases for several years. Overexposure to
isocyanates has also been reported to cause lung
damage (including decrease in lung function), which may
be permanent. Sensitization can either be temporary or
permanent.
ACUTE SKIN CONTACT:................................. Isocyanates react with skin protein and moisture and can
cause irritation, which may include the following
symptoms: reddening, swelling, rash, scaling or
blistering. Cured material is difficult to remove.
CHRONIC SKIN CONTACT:............................ Prolonged contact can cause reddening, swelling, rash,
scaling, blistering and in some cases, skin sensitization.
Individuals who have skin sensitization can develop
these symptoms from contact with liquid or vapors.
ACUTE EYE CONTACT:................................. Liquid, aerosols or vapors are irritating and can cause
.
tearing, reddening and swelling. If left untreated, corneal
damage can occur and injury is slow to heal. However,
damage is usually reversible.
CHRONIC EYE CONTACT: ............................. None Found
ACUTE INGESTION:........................................ Can result in irritation and corrosive action in the mouth,
stomach tissue and digestive tract. Symptoms can
include sore throat, abdominal pain, nausea, vomiting
and diarrhea.
CHRONIC INGESTION: ................................... None Found
None of the components are listed as carcinogens.
