Section 3. Hazards Identification
Emergency Overview:
DANGER ! MAY BE FATAL IF SWALLOWED, INHALED OR ABSORBED THROUGH SKIN,
AFFECTS LIVER, KIDNEYS, CENTRAL NERVOUS SYSTEM AND GASTROINTESTINAL
1
TRACT, CAUSES SEVERE IRRITATION TO EYES, SKIN AND RESPIRATORY TRACT.
FLAMMABLE, HAZARD SYMBOLS: F
Persons with pre-existing skin, eye or central nervous system disorders or impaired liver, kidney or
pulmonary function may be more susceptible to the effects of this substance.
Potential Health Effects:
INHALATION: High concentrations are irritating to the mucus membranes of the upper respiratory tract,
may cause headache, ringing in the ears, dizziness, nausea, vomiting and severe breathing difficulties.
High vapor concentrations are anesthetic and central nervous system depressants.
SKIN: Brief contact may cause slight irritation, loss of natural oils, prolonged contact may cause moderate
irritation or dermatitis. This problem may be accentuated by liquid becoming trapped against the skin by
contaminated clothing or shoes.
EYES: High vapor concentration or contact may cause irritation, discomfort or pain. May cause slight
transient corneal injury. Splashes may cause severe irritation. Possible corneal burns and eye damage.
INGESTION: Swallowing of this material may result in irritation of the mouth and GI tract. Vomiting and
subsequent aspiration into the lungs may lead to a severe hemorrhagic pneumonitis with severe pulmonary
injury or death..
CARCINOGENICITY: Xylene is listed in Group 3 by IARC (monograph), 鈥淣ot classifiable as
carcinogenic in humans鈥?, listed by ACGIH, Appendix 4 as 鈥淣ot Classifiable as a human carcinogen 鈥?.
OSHA PEL and NIOSH REL: 100 ppm, 435 mg/m3.
Section 4- First Aid Measures
INHALATION: Remove affected person to fresh air, provide oxygen if breathing is difficult, if affected
person is not breathing administer CPR, do not use mouth-to-mouth resuscitation, seek emergency medical
attention.
SKIN: Remove contaminated clothing, wash affected area with soap and water, launder contaminated
clothing before reuse, if irritation persists seek medical attention.
EYES: Remove contact lenses, flush eyes with clear running water for 15 minutes while holding eyelids
open, if irritation persists seek immediate medical attention.
INGESTION: Aspiration hazard, DO NOT induce vomiting. If vomiting occurs keep head below hips to
prevent aspiration into lungs. Take affected person immediately to a hospital, do not give anything by
mouth to an unconscious person.
Section 5- Fire Fighting Measures
FLASH POINT (METHOD USED): 84掳F (Closed Cup)
FLAMMABLE LIMITS: LEL 1.0 %; UEL 7.0%
AUTOIGNITION TEMPERATURE: Xylene: 464掳C NFPA Class: IC
EXTINGUISHING MEDIA: Carbon dioxide, water, water fog, dry chemical, chemical foam. Water in
straight hose stream should be avoided as it can scatter and spread existing burning liquid.
FIRE FIGHTING PROCEDURES: Self-contained respiratory equipment, cool containers to prevent
build-up and possible explosion when exposed to extreme heat. CAUTION- MATERIAL IS
FLAMMABLE !
UNUSUAL FIRE AND EXPLOSION HAZARDS: Closed containers can explode due to build-up of
pressure when exposed to extreme heat. Sensitive to static discharge.
HAZARDOUS COMBUSTION PRODUCTS: Irritating or toxic substances such as carbon oxides may be
emitted upon thermal decomposition.
Section 6- Environmental Release Measures
STEPS TO BE TAKEN IN CASE MATERIAL IS RELEASED OR SPILLED: Remove all sources of
ignition and use non-sparking tools and equipment. Evacuate and ventilate area, confine and absorb into
2
inert absorbent (vermiculite, dry sand, earth, DO NOT use combustible materials like sawdust); do not
flush to sewer, place material into approved containers for disposal; for spills in excess of allowable limits
(RQ) notify the National Response Center (800-424-8802); refer to CERCLA 40 CFR 302 and SARA
Title III, Section 313, 40 CFR 372 for detailed instructions concerning reporting requirements. DO NOT
enter low-lying areas without self-contained breathing apparatus where vapors may be present. Inhalation
could be fatal.
Section 7- Handling and Storage
PRECAUTIONS TO BE TAKEN IN HANDLING AND STORAGE: Keep container closed when not in
use; protect containers from abuse , extreme temperatures and separate from incompatibles.. CAUTION
FLAMMABLE- keep away from all sources of ignition. 鈥淓mpty鈥? containers may contain residue which
may form explosive vapors. Do not weld or cut near empty container that has not been professionally
reconditioned. Use non-sparking tools when opening and closing containers. Maintain well ventilated
work areas to minimize exposure when handling this material. Avoid inhaling concentrated fumes or
vapors.
Section 8- Exposure Controls/Personal Protection
ENGINEERING CONTROLS:
The use of local exhaust ventilation is recommended to control emissions near the source and keep
employee exposures below the Airborne Exposure Limits. Provide Self-contained Breathing Apparatus for
workers entering confined spaces. Provide mechanical ventilation of confined spaces. Use explosion-
proof ventilation equipment. See Section 2 for component exposure guidelines.
PERSONAL PROTECTION:
RESPIRATORY PROTECTION: None required while threshold limits (Section 2) are kept below
maximum allowable concentrations: if TWA exceeds limits NIOSH approved respirator must be worn.
Refer to 29 CFR 1910.134 or European Standard EN 149 for complete regulations. DO NOT enter low-
lying areas without self-contained breathing apparatus.
PROTECTIVE GLOVES: neoprene or rubber gloves with cuffs to prevent skin contact
EYE PROTECTION: Safety goggles with side shields of full face shield where splashing is possible.
OTHER PROTECTIVE CLOTHING OR EQUIPMENT: Chemical impervious apron, safety eyebath
nearby.
WORK/ HYGIENIC PRACTICES: Practice safe workplace habits. Minimize body contact with this as
well as all chemicals in general.
Section 9- Physical and Chemical Properties
BOILING POINT: 173 掳F VAPOR PRESSURE @ 68掳F: 8 mm Hg
VAPOR DENSITY: (air = 1): 3.78 SOLUBILITY IN WATER: complete
VISCOSITY: similar to water EVAPORATION RATE (n-butyl acetate =1): 0.7
FREEZING POINT: not determined PHYSICAL STATE: liquid
VOLATILE ORGANIC CMPDS (total VOCs): 8.97 lbs/gal
Section 10- Stability and Reactivity
STABILITY: Stable CONDITIONS TO AVOID: extreme temps, open flames, sparks
INCOMPATABILITY (materials to avoid): strong oxidizers and strong acids.
HAZARDOUS DECOMPOSITION OR BYPRODUCTS: Decomposition will not occur if handled and
stored properly, in case of fire oxides of carbon, hydrocarbons, fumes and toxic smoke may be produced.
HAZARDOUS POLYMERIZATION: will not occur
