released in fire situations. May cause eye irritation or
corneal injury. May be absorbed through the skin and
causes skin irritation. Potential skin sensitizer. Toxic to
aquatic organisms and avian.
EMERGENCY PHONE NUMBER: 800-992-5994
4. FIRST AID:
EYES: Hold eyes open and rinse slowly and gently with
water for 15-20 minutes. Remove contact lenses, if present,
after the first 5 minutes, and then continue rinsing eyes.
Call a poison control center or doctor for treatment advice.
SKIN: Take off contaminated clothing. Wash skin with soap
and plenty of water for 15-20 minutes. Call a poison control
center or doctor for treatment advice. Wash clothing before
reuse. Shoes and other leather items which cannot be
decontaminated should be disposed of properly.
INGESTION: Call poison control center or doctor
immediately for treatment advice. Have person sip a glass
of water if able to swallow. Do not induce vomiting unless
told to do so by the poison control center or doctor. Never
give anything by mouth to an unconscious person.
INHALATION: Move person to fresh air. If person is not
breathing, call 911 or an ambulance, and then give artificial
respiration; if by mouth to mouth use rescuer protection
(pocket mask, etc.). Call a poison control center or doctor
for treatment advice. If breathing is difficult, oxygen should
be administered by qualified personnel.
NOTE TO PHYSICIAN: Because rapid absorption may
occur through lungs if aspirated and cause systemic
effects, the decision of whether to induce vomiting or not
should be made by a physician. If lavage is performed,
suggest endotracheal and/or esophageal control. Danger
from lung aspiration must be weighed against toxicity when
considering emptying the stomach. Respiratory symptoms,
including pulmonary edema, may be delayed. Persons
receiving significant exposure should be observed 24-48
hours for signs of respiratory distress. Maintain adequate
ventilation and oxygenation of the patient. Repeated
excessive exposure may aggravate preexisting lung, liver,
and kidney disease. If burn is present, treat as any thermal
burn, after decontamination. Animal data indicates that this
material is a potential skin sensitizer. However, skin
sensitization has not been encountered among employees
involved in the manufacture of this material. Treatment of
exposure should be directed at the control of symptoms
and the clinical condition of the patient.
5. FIRE FIGHTING MEASURES:
FLASH POINT: 81.5°F (27.5°C)
METHOD USED: TCC
FLAMMABLE LIMITS

FIRE & EXPLOSION HAZARDS: Keep unnecessary
people away; isolate hazard area and deny unnecessary
entry. Highly toxic and irritating fumes are released in fire
situations. Keep product vapors away from possible ignition
sources. Vapors can form flammable mixtures at ordinary
temperatures. Static electricity may accumulate and create
a fire ignition. Vapors are heavier than air and may travel a
considerable distance where they may linger and/or find an
ignition source and flash back. Stay upwind; keep out of low
areas.
FIRE-FIGHTING EQUIPMENT: Use NIOSH or MSHA
approved positive-pressure, self-contained breathing
apparatus and special protective clothing, including heavy
neoprene or rubber boots and neoprene gloves.

providing gas-tight protection is required to prevent
possible skin effects (read product label).
CLEAN-UP FOR SMALL SPILLS:
If it can be done safely, invert or reposition the leaking
container of product so that the area with the leak is up and
the flow is reduced. If possible, put the container into an
overpak. Cover or confine the leakage with an absorbent
such as diatomaceous earth, clay, sand, or other non-
combustible absorptive material. Collect the spent
absorbent material in a disposal drum. If the spill is on the
ground, dig up enough of the soil to eliminate the
contamination and place the soil in a disposal drum.
