RTECS No:
XS5250000
Properties:
Highly Flammable, clear,
colorless, watery, volatile liquid. Sweet, strong, pleasant, benzene-, or model
glue-like odor. Only a small amount will dissolve; the rest floats on water.
Vapors are heavier than air; will collect in low areas.
Uses:
Solvent for metal coatings, adhesives, paint
removers, fats, gums, oils, bitumens, resins, lacquers, waxes; degreasing of
metals; component of industrial cleaning compounds; gasoline additive.
HEALTH & SAFETY INFORMATION
• IDLH:
500 ppm (1885 mg/m
3
)
• IARC:
Group 3, inadequate animal and human
evidence.
• Odor threshold:
0.60 - 139.5 mg/m

• NIOSH Criteria Document
: NIOSH 73-11023
• OSHA Table Z-1 Air Contaminant
• OSHA Table Z-2 Air Contaminant
• Chemical protective clothing is recommended
because vapor and liquid can be dermally absorbed and may contribute to
systemic toxicity. Irritates the eyes and respiratory tract. Exposure could
cause central nervous system depression. Exposure at high levels may result in
cardiac dysrhythmia, unconsciousness, and death. Chronic toluene exposures at
<200 ppm have been associated with headache, fatigue, and nausea. Workers
repeatedly exposed to 200 to 500 ppm have reported loss of coordination, memory
loss, and loss of appetite. Some workers have developed reversible disorders of
the optic nerves after chronic exposure sin the workplace. May affect the
central nervous system, resulting in decreased learning ability and
psychological disorders. Chronic exposure due to solvent abuse can result in
permanent neuropsychiatric effects. Disorders of the muscles, cardiovascular
effects, renal tubular damage, and sudden death have occurred in chronic
abusers of toluene (e.g., glue sniffers). Chronic skin exposure may cause
dermatitis. Blood effects and anemia have been reported; may be due to
contamination by benzene. Based on animal tests, this chemical may be a
reproductive toxin with developmental consequences.

CCRFOV[any air-purifying,
full-facepiece respirator (gas mask) with a chin-style, front- or back-mounted
acid gas canister] PAPROV [any powered, air-purifying respirator with organic
vapor cartridge(s)] GMFOV(any air-purifying, fullfacepiece respirator (gas
mask) with a chin-style, frontor back-mounted organic vapor canister] SA (any

full facepiece).
Emergency
or Planned Entry into Unknown Concentrations or IDLH Conditions
SCBAF:PD,PP (any
self-contained breathing apparatus that has a full facepiece and is operated in
a pressure-demand or other positivepressure mode) SAF:PD,PP:ASCBA (any
suppliedair respirator that has a full facepiece and is operated in a
pressure-demand or other positive-pressure mode in combination with an
auxiliary self-contained breathing apparatus operated in a pressure-demand or
other positive-pressure mode).
Escape:
GMFOV [any airpurifying, full-facepiece
respirator (gas mask) with a chin-style, front- or back-mounted organic vapor
canister] SCBAE (any appropriate escape-type, elfcontained breathing
apparatus).
Reactivity:
Forms explosive mixture with
air (flash point 39°F/4°C). Violent reaction with strong oxidizers, bromine,
bromine trifluoride, chlorine, hydrochloric acid-sulfuric acid mixture,
1,3-dichloro-5,5-dimethyl- 2,4-imidazolididione, dinitrogen tetraoxide,
fluorine, nitric acid (concentrated), nitrogen dioxide, silver chloride, sulfur
dichloride, uraniumfluoride, vinyl acetate. Forms explosive mixture with
strong acids, strong oxidizers, silver perchlorate, tetranitromethane.
Incompatible with
bis
-toluenediazo oxide. Attacks
some plastics, rubber, and coatings. Flow or agitation of substance may
generate electrostatic charges due to low conductivity.
FIRE INFORMATION:
This material is a
significant ire hazard at room temperature. Vapors may travel long distances to
ignition sources and flash back. Vapors in confined areas or containers may
explode in fire. If material or contaminated runoff enters waterways, notify
downstream users of potentially contaminated water.

FIRST AID:
Move victim to fresh air.
Call emergency medical care. Apply artificial respiration if victim is not
breathing. Administer oxygen if breathing is difficult. Remove and isolate
contaminated clothing and shoes. In case of contact with substance, immediately
flush skin or eyes with running water for at least 20 minutes. Wash skin with
soap and water. Keep victim warm and quiet. Effects of exposure (inhalation,
ingestion or skin contact) to substance may be delayed. Ensure that medical
personnel are aware of the material(s) involved, and take precautions to
protect themselves.
