Hazard Symbols: XN
Risk Phrases: 10 20/21 38
Section 3 - Hazards Identification
Appearance: clear, colorless liquid. Flash Point: 77 deg F.
Flammable liquid and vapor.
May cause central nervous system depression. May cause liver and
kidney damage. Aspiration hazard if swallowed. Can enter lungs and
cause damage. Causes respiratory tract irritation.
Warning! Causes eye irritation. Prolonged or repeated
contact may dry the skin and cause irritation. May be harmful if
absorbed through skin or if inhaled. This substance has caused
adverse reproductive and fetal effects in animals.
Target Organs: Blood, kidneys, central nervous
system, liver, lungs, eyes, skin, mucous membranes.
Potential Health Effects
Causes severe eye irritation. Splashes of xylene in human eyes
generally cause transient superficial injury.
May be harmful if absorbed through the skin. Xylene contact causes
defatting of the skin with irritation, dryness, and cracking.
Blistering may occur, particularly if exposure to concentrated xylene
is prolonged and the exposed area of skin is occluded.
Aspiration hazard. May cause irritation of the digestive tract. May
cause central nervous system depression, characterized by
excitement, followed by headache, dizziness, drowsiness, and nausea.
Advanced stages may cause collapse, unconsciousness, coma and
possible death due to respiratory failure. May cause effects similar
to those of acute inhalation.
Inhalation of high concentrations may cause central nervous system
effects characterized by nausea, headache, dizziness, unconsciousness
and coma. Prolonged exposure may result in dizziness and general
weakness. Irritation may lead to chemical pneumonitis and pulmonary
edema. May cause liver and kidney damage. Causes irritation of
mucous membrane. Exposure may cause blood abnormalities. Odor is not
an adequate warning for overexposure to xylene.
Chronic exposure to xylene may cause defatting dermatitis,
reversible eye damage, dyspnea (labored breathing), confusion,
dizziness, apprehension, memory loss, headache, tremors, weakness,
anorexia, nausea, ringing in the ears, irritability, thirst, mild
changes in liver function, kidney impairment, anemia, and
hyperplasia, but not destruction, of the bone marrow.
Section 4 - First Aid Measures
In case of contact, immediately flush eyes with plenty of water for
at least 15 minutes. Get medical aid.
In case of contact, flush skin with plenty of water. Remove
contaminated clothing and shoes. Get medical aid if irritation
develops and persists. Wash clothing before reuse.
Potential for aspiration if swallowed. Get medical aid immediately.
Do not induce vomiting unless directed to do so by medical
personnel. Never give anything by mouth to an unconscious person.
If inhaled, remove to fresh air. If not breathing, give artificial
respiration. If breathing is difficult, give oxygen. Get medical aid.
Notes to Physician:
Treat symptomatically and supportively.
Section 5 - Fire Fighting Measures
As in any fire, wear a self-contained breathing apparatus in
pressure-demand, MSHA/NIOSH (approved or equivalent), and full
protective gear. Flammable liquid and vapor. Vapors may form an
explosive mixture with air. Vapors are heavier than air and may
travel to a source of ignition and flash back. Vapors can spread
along the ground and collect in low or confined areas. This liquid
floats on water and may travel to a source of ignition and spread
fire. May accumulate static electricity.
Use water spray to cool fire-exposed containers. Water may be
ineffective. This material is lighter than water and insoluble in
water. The fire could easily be spread by the use of water in an
area where the water cannot be contained. Use water spray, dry
chemical, carbon dioxide, or appropriate foam.
Flash Point: 77e deg F ( 25.00 deg C)
Autoignition Temperature: 984 deg F ( 528.89 deg C)
Explosion Limits, Lower:1.1%
(estimated) Health: 2; Flammability: 3; Instability: 0
Section 6 - Accidental Release Measures
General Information: Use proper personal protective equipment as indicated
in Section 8.
Absorb spill with inert material (e.g. vermiculite, sand or earth),
then place in suitable container. Remove all sources of ignition.
Provide ventilation. A vapor suppressing foam may be used to reduce
vapors. Water spray may reduce vapor but may not prevent ignition in
closed spaces. U.S. regulations require reporting spills and releases
to soil, water and air in excess of reportable quantities. This
material creates a fire hazard because it floats on water. If
possible, try to contain floating material.
Section 7 - Handling and Storage
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Ground and bond containers when transferring
material. Avoid contact with eyes, skin, and clothing. Empty
containers retain product residue, (liquid and/or vapor), and can be
dangerous. Do not pressurize, cut, weld, braze, solder, drill, grind,
or expose empty containers to heat, sparks or open flames. Use only
with adequate ventilation. Keep away from heat, sparks and flame.
Avoid breathing vapor or mist.
Keep away from sources of ignition. Keep container closed when not
in use. Keep from contact with oxidizing materials. Store in a cool,
dry, well-ventilated area away from incompatible substances. Keep
away from strong acids.
Section 8 - Exposure Controls, Personal Protection
Facilities storing or utilizing this material should be equipped
with an eyewash facility and a safety shower. Use adequate general or
local exhaust ventilation to keep airborne concentrations below the
permissible exposure limits.

In air, xylenes degrade by reacting with photochemically produced
hydroxyl radicals. In soil it will volatilize and leach into
groundwater. Little bioconcentration is expected.
ATMOSPHERIC FATE: According to a model of gas/particle partitioning
of semivolatile organic compounds in the atmosphere, xylene, which
has an experimental vapor pressure of 7.99 mm Hg at 25 deg C, will
exist solely as a vapor in the ambient atmosphere. Vapor-phase xylene
is degraded in the atmosphere by reaction with
photochemically-produced hydroxyl radicals; the atmospheric lifetime
of xylene is about 14-26 hours. Ambient levels of xylene are detected
in the atmosphere due to large emissions of this compound.
Section 13 - Disposal Considerations
Chemical waste generators must determine whether a discarded chemical is classified
as a hazardous waste.
US EPA guidelines for the classification determination are listed in 40 CFR Parts 261.3.
Additionally, waste generators must consult state and local hazardous waste regulations to
ensure complete and accurate classification.
