SECTION 4 - FIRST AID MEASURES
Eye Contact: Immediately flush eyes with copious amounts of water for a minimum of 15 minutes, holding lids
open with fingers. If irritation persists, repeat flushing. Refer individual to a physician for immediate follow-up.
Skin Contact: Remove contaminated clothing and/or shoes. Immediately wash affected area thoroughly with
soap and water. Some organic materials such as corn oil or propylene glycol can aid in the removal of PMDI from
the skin when applied immediately. Contaminated clothing should be thoroughly cleaned before reuse. If
irritation, redness, or a burning sensation develops and persists, obtain medical advice.
Inhalation: Remove patient from further exposure and obtain medical attention. Treatment is symptomatic for
primary irritation or difficulty in breathing. If breathing is labored, qualified personnel should administer oxygen.
Apply artificial respiration if breathing has ceased or shows signs of failing. Asthmatic-like symptoms, if
manifested, may develop immediately, or be delayed for up to several hours.
Ingestion: Do NOT induce vomiting. Provided the patient is conscious, wash mouth out with water. Refer
person to medical personnel for immediate attention.
Note to Physicians: Symptomatic and supportive therapy as indicated. Following severe exposure, medical
follow-up should be monitored for at least 48 hours.

SECTION 6 - ACCIDENTAL RELEASE MEASURES
Clear the area surrounding the spilled material and prevent further spillage, leakage or entry into drains. Eye and
skin protection should be worn during spill cleanup and ventilation maintained. If the potential for airborne
concentrations of MDI above the PEL exists, then respiratory protection should be worn. Contain and cover spill
with loose absorbent (earth, sand, sawdust or other absorbent material), or absorbent pillows, pads or socks.
Collect absorbed material in open containers or plastic bags, and treat with deactivating solution (90% water, 8%
concentrated ammonia, 2% detergent). Allow to stand uncovered for 48-72 hours to permit carbon dioxide to
escape and solidification to occur. Wash spill area with deactivating solution and let stand for 30 minutes or
longer. Dispose of absorbed and neutralized material properly.

Exposure Guidelines: Medical supervision of employees who come into contact with respiratory sensitizers is
recommended. Persons with asthmatic-type conditions, chronic bronchitis, other chronic respiratory diseases or
recurrent skin eczema or sensitization should be excluded from working with this product. Once a person is
sensitized, no further exposure to the material that caused the sensitization should be permitted. Avoid inhalation
of mists and vapors. Avoid skin contact.
Respiratory Protection: Due to the low vapor pressure of this material, the PEL is not likely to be exceeded under
normal conditions. If the material is heated or spilled in a confined area, respiratory protection should be worn.
An approved air purifying respirator equipped with an organic vapor cartridge and a HEPA (P100) particulate
filter may be used when an appropriate cartridge change-out schedule has been developed in accordance with the
OSHA respiratory protection standard (29 CFR 1910.134). Where concentrations exceed the level for which an
air-purifying respirator is effective, use a positive pressure, supplied air respirator.
Eye Protection: Safety glasses with side shields or goggles.

LC50 Inhalation:
370-490 mg/m3/4 hour (rat) for polymeric MDI
Primary Route(s) of Exposure: Skin contact from liquid. Inhalation. However, due to the low vapor pressure,
overexposure is not expected under normal conditions unless material is heated or used in a poorly ventilated
area.
Inhalation: This product is a respiratory irritant and respiratory sensitizer. Inhalation of vapor or aerosol at levels
above the occupational exposure limit can cause respiratory sensitization. Symptoms may include irritation to the
eyes, nose, throat, and lungs, possibly combined with dryness of the throat, tightness of chest and difficulty in
breathing. The onset of respiratory symptoms may be delayed for several hours after exposure.

SECTION 11 - TOXICOLOGICAL INFORMATION (continued)
A hyper-reactive response to even minimal concentrations of MDI may develop in sensitized persons. Sensitized
persons should be removed from any further exposure. Persons with asthma-type conditions or other chronic
respiratory diseases should be excluded from working with MDI. Like many other non-specific asthmatic
responses, there are reports that a sensitized individual can experience symptoms upon exposure to dust, cold air
or other irritants. In a single evaluation of 5 men occupationally exposed to MDI and hydrocarbon solvent vapors
under conditions where adequate ventilation or other safety precautions were not used, neuropsychologic findings
were attributed to MDI.
Skin Contact: Skin irritant and sensitizer. May cause irritation or rash. Can cause skin discoloration. Repeated
and/or prolonged contact may result in skin sensitization. Individuals who have skin sensitization can develop
symptoms (e.g., reddening swelling, rash) from contact with liquid or vapors. There is limited evidence from
laboratory tests that skin contact may play a role in respiratory sensitization. This data reinforces the need to
prevent direct skin contact and the importance of protective gloves.
Eye Contact: Liquid can cause eye irritation, tearing, reddening and swelling. Permanent corneal injury is
unlikely. Exposure to MDI vapors in excess of 0.02 ppm may cause irritation.
Ingestion: Ingestion is unlikely. Based on the acute oral LD50, this product is considered practically non-toxic by
ingestion. Ingestion can cause irritation and corrosive action in the mouth, stomach and digestive tract.
Chronic Effects: A study was conducted where groups of rats were exposed for 6 hours/day, 5 days/week for a
lifetime to atmospheres of respirable polymeric MDI aerosol either at concentrations of 0, 0.2, 1, or 6 mg/m3. No
adverse effects were observed at 0.2 mg/m3 concentrations. At the 1 mg/m3 concentration, minimal nasal and lung
irritant effects were seen. Only at the highest concentration (6 mg/m3) was there an increased incidence of benign
tumor of the lung (adenoma) and one malignant tumor (adenocarcinoma). MDI administration to rats in this study
did not change the distribution and incidence of tumors from those seen in control animals. The increased
incidence of lung tumors is associated with prolonged respiratory irritation and the concurrent accumulation of
yellow material in the lung. In the absence of prolonged exposure to high concentrations leading to chronic
irritation and lung damage, it is highly unlikely that tumor formation will occur.
Carcinogenicity: The ingredients of this product (>0.1%) are not classified as carcinogenic by ACGIH or IARC,
not regulated as carcinogens by OSHA and not listed as carcinogens by NTP.
Mutagenicity: There is no substantial evidence of mutagenic potential.
Reproductive Effects: No adverse reproductive effects are anticipated.
Teratogenicity and Fetotoxicity: No birth defects were seen in two independent animal (rat) studies. Fetotoxicity
was observed at doses that were extremely toxic (including lethal) to the mother. The dose that produced this
effect (1.2 ppm) is 60 times higher than the OSHA-PEL. Fetotoxicity was not observed at doses that were not
maternally toxic. The doses used in these studies were maximal, respirable concentrations well in excess of the
defined occupational exposure limits.
SECTION 12 - ECOLOGICAL INFORMATION
Environmental Fate and Distribution: It is unlikely that significant environmental exposure in the air or water will
arise, based on consideration of the production and use of the substance.
