3. HAZARDS IDENTIFICATION
Potential Health Effects
Eye
Can cause eye irritation. Symptoms include stinging, tearing,
redness, and swelling of eyes.
Skin
Can cause skin irritation. Prolonged or repeated contact may dry
the skin. Symptoms may include redness, burning, and drying and
cracking of skin, burns and other skin damage. Passage of this
material into the body through the skin is possible, but it is
unlikely that this would result in harmful effects during safe
handling and use.
Swallowing
Swallowing small amounts of this material during normal handling
is not likely to cause harmful effects. Swallowing large amounts
may be harmful. This material can get into the lungs during
swallowing or vomiting. This results in lung inflammation and
other lung injury.
Inhalation
Breathing of vapor or mist is possible. Breathing this material
may be harmful. Symptoms usually occur at air concentrations
higher than the recommended exposure limits (See Section 8).
Symptoms of Exposure
Signs and symptoms of exposure to this material through breathing,
swallowing, and/or passage of the material through the skin may
include: stomach or intestinal upset (nausea, vomiting, diarrhea)
irritation (nose, throat, airways), central nervous system
depression (dizziness, drowsiness, weakness, fatigue, nausea,
headache, unconsciousness), central nervous system depression
(dizziness, drowsiness, weakness, fatigue, nausea, headache,
unconsciousness) and other central nervous system effects,
irregular heartbeat, elevated carbon monoxide levels in the blood,
and death.
Target Organ Effects
Overexposure to this material (or its components) has been
suggested as a cause of the following effects in laboratory
animals: kidney damage, liver damage.
Developmental Information
This material (or a component) has been shown to cause harm to the
fetus in laboratory animal studies. Harm to the fetus occurs only
at exposure levels that harm the pregnant animal. The relevance
of these findings to humans is uncertain.
Cancer Information
This material (or a component) causes cancer in laboratory animals
and therefore may present a carcinogenic risk to humans. This
material (or a component) is listed as a carcinogen by the
International Agency for Reseach on Cancer and the National
Toxicology Program.
Other Health Effects
No data
Primary Route(s) of Entry
Inhalation, Skin absorption, Skin contact, Eye contact.
__________________________________________________________________________
4. FIRST AID MEASURES
Eyes
If symptoms develop, immediately move individual away from
exposure and into fresh air. Flush eyes gently with water for at
least 15 minutes while holding eyelids apart; seek immediate
medical attention.
Skin
Remove contaminated clothing. Flush exposed area with large
amounts of water. If skin is damaged, seek immediate medical
attention. If skin is not damaged and symptoms persist, seek
medical attention. Launder clothing before reuse.
Swallowing
Seek medical attention. If individual is drowsy or unconscious,
do not give anything by mouth; place individual on the left side
with the head down. Contact a physician, medical facility, or
poison control center for advice about whether to induce vomiting.
If possible, do not leave individual unattended.
Inhalation
If symptoms develop, immediately move individual away from
exposure and into fresh air. Seek immediate medical attention;
keep person warm and quiet. If person is not breathing, begin
artificial respiration. If breathing is difficult, administer
oxygen.
Note to Physicians
Inhalation of high concentrations of this material, as could occur
in enclosed spaces or during deliberate abuse, may be associated
with cardiac arrhythmias. Sympathomimetic drugs may initiate
cardiac arrhythmias in persons exposed to this material. This
material is an aspiration hazard. Potential danger from
aspiration must be weighed against possible oral toxicity (See
Section 3 - Swallowing) when deciding whether to induce vomiting.
Preexisting disorders of the following organs (or organ systems)
may be aggravated by exposure to this material: skin, lung (for
example, asthma-like conditions), liver, kidney, Exposure to this
material may aggravate any preexisting condition sensitive to a
decrease in available oxygen, such as chronic lung disease,
coronary artery disease or anemias. Individuals with preexisting
heart disorders may be more susceptible to arrhythmias (irregular
heartbeats) if exposed to high concentrations of this material.

5. FIRE FIGHTING MEASURES
Flash Point
Not applicable
Explosive Limit
Not applicable
Autoignition Temperature
No data
Hazardous Products of Combustion
May form: carbon dioxide and carbon monoxide, chlorine, hydrogen
chloride, phosgene.
Fire and Explosion Hazards
No flash to boiling point. This product contains halogenated
solvents which inhibit flashing until the halogenated solvent has
been evaporated away. The product may become combustible or
flammable after this occurs. Vapors are heavier than air and may
travel along the ground or may be moved by ventilation and ignited
by pilot lights, other flames, sparks, heaters, smoking, electric
motors, static discharge, or other ignition sources at locations
distant from material handling point.
Extinguishing Media
water fog, carbon dioxide, dry chemical.
Fire Fighting Instructions
Wear a self-contained breathing apparatus with a full facepiece
operated in the positive pressure demand mode with appropriate
turn-out gear and chemical resistant personal protective
equipment. Refer to the personal protective equipment section of
this MSDS.
NFPA Rating
Health - 2, Flammability - 1, Reactivity - 0
__________________________________________________________________________
6. ACCIDENTAL RELEASE MEASURES
Small Spill
Absorb liquid on vermiculite, floor absorbent or other absorbent
material. Persons not wearing proper personal protective
equipment should be excluded from area of spill.
Large Spill
Prevent run-off to sewers, streams or other bodies of water. If
run-off occurs, notify proper authorities as required, that a
spill has occurred. Persons not wearing protective equipment
should be excluded from area of spill until clean-up has been
completed. Stop spill at source, dike area of spill to prevent
spreading, pump liquid to salvage tank. Remaining liquid may be
taken up on sand, clay, earth, floor absorbent, or other absorbent
material and shoveled into containers.
__________________________________________________________________________
7. HANDLING AND STORAGE
Handling
Containers of this material may be hazardous when emptied. Since
emptied containers retain product residues (vapor, liquid, and/or
solid), all hazard precautions given in the data sheet must be
observed.
Storage
Aluminum equipment should not be used for storage and/or transfer,
e.g. pumps, mixers, fittings, storage tanks, etc. Contact with
aluminum parts in a pressurizable fluid system may cause violent
reactions.

8. EXPOSURE CONTROLS/PERSONAL PROTECTION
Eye Protection
Chemical splash goggles in compliance with OSHA regulations are
advised; however, OSHA regulations also permit other type safety
glasses. Consult your safety representative.
Skin Protection
Wear resistant gloves (consult your safety equipment supplier).,
To prevent skin contact, wear impervious clothing and boots..
Respiratory Protections
If workplace exposure limit(s) of product or any component is
exceeded (see exposure guidelines), a NIOSH/MSHA approved air
supplied respirator is advised in absence of proper environmental
control. OSHA regulations also permit other NIOSH/MSHA
respirators (negative pressure type) under specified conditions
(see your industrial hygienist). Engineering or administrative
controls should be implemented to reduce exposure. See 29 CFR
1910.1052 for specific OSHA requirements for employee exposure to
methylene chloride.
Engineering Controls
Provide sufficient mechanical (general and/or local exhaust)
ventilation to maintain exposure below TLV(s).
