POTENTIAL HEALTH EFFECTS
EYE: Vapors may cause irritation. Splashes may cause temporary damage to the surface of the eye.
SKIN: Repeated contact can dry and defat the skin causing redness, peeling and cracking. May cause allergic skin reaction
(dermatitis) in sensitive workers.
INHALATION: Inadequate ventilation may result in overexposure to solvents. Inhalation of high vapor concentrations can
cause respiratory irritation and CNS depression.
CHRONIC: Epidemiologic studies among rubber products workers has noted excess deaths from various cancers.
CARCINOGENICITY: IARC: Yes NTP: Yes OSHA: Yes
IARC lists the rubber industry as an exposure circumstance that "entails exposures that are carcinogenic to humans". This
product contains carbon black, a substance that has caused cancer in experimental animals and is classified as a possible
human carcinogen by IARC (Group 2B). Carbon black is bound in a rubber matrix and release is not expected under normal
conditions. IARC classifies ethylbenzene as a possible human carcinogen (Group 2B).
MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE: Irritant properties may aggravate pre-existing eye, skin, and
respiratory conditions.
SIGNS AND SYMPTOMS: CNS depression may cause dizziness, excitement, drowsiness, staggering, nausea, and
vomiting. Continued overexposure may result in unconsciousness and death.
TARGET ORGANS: Eyes, skin, respiratory system, CNS
4. FIRST AID MEASURES
EYE CONTACT: Immediately flush eyes with lukewarm water for at least 15 minutes. If irritation persists, consult an
ophthalmologist.
SKIN: Remove contaminated clothing and wash skin thoroughly with soap and water. If irritation persists or rashes occur,
get medical attention.
INHALATION: Immediately remove to fresh air. If breathing problems occur, give supplemental oxygen or artificial
respiration as indicated and obtain immediate medical attention.
OTHER: If accidental ingestion occurs, DO NOT INDUCE VOMITING due to potential for aspiration and/or CNS
depression. Consult a physician.

HEALTH: 2 FLAMMABILITY: 3 INSTABILITY: 0
* Data given are the manufacturer's values for the solvent.
EXTINGUISHING MEDIA: Dry chemical, foam, carbon dioxide or water spray. Water may be ineffective to fight fire due to
low flashpoint, but may be used to cool surrounding materials.
FIRE AND EXPLOSION HAZARDS: Flammable liquid. May accumulate static electricity. Dangerous fire and explosion
hazard. Avoid heat, sparks, and flames. Vapors are heavier than air and may collect in low-lying areas or travel a distance
along the ground to an ignition source and flash back. Xylene floats on water and may travel to an ignition source and
spread fire. Container may rupture violently from pressure when heated. Thermal decomposition may form carbon oxides,
hydrocarbons, isoprene derivatives, sulfur compounds, and other oxidation products.

15. FIREFIGHTING MEASURES (continued)
FIRE FIGHTING INSTRUCTIONS: Firefighters should wear a NIOSH-approved, full-facepiece self-contained breathing
apparatus (SCBA) operated in positive pressure mode and full turnout or bunker gear with additional chemical protective
clothing as necessary to protect against thermal decomposition products. Continue to cool fire-exposed containers until well
after flames are extinguished. Move containers from fire area if it can be done without risk. Dike run-off waters from
firefighting for later disposal.
6. ACCIDENTAL RELEASE MEASURES
Immediately extinguish all ignition sources and isolate area of spill. No smoking, sparks, flares or flames in hazard area.
Stop or control the leak if it can be cone without risk. Wear appropriate personal protective equipment (See Section 8) and
deny entry to unauthorized and unprotected personnel. Use water spray or vapor suppressing foam as necessary to control
vapors. Absorb small amounts in suitable inert sorbent material and carefully scoop or shovel into clean, dry, tightly closed
container for later disposal. Dike well ahead of large spills for later recycle or disposal. Prevent entry into waterways and
sewers. Run-off to sewer may cause fire or explosion. Use clean, non-sparking tools to collect spilled materials.
7. HANDLING AND STORAGE
Store in cool, dry, well-ventilated area. Handle and store as a flammable liquid. Detached storage is preferred. Storage
containers should be clearly labeled, kept upright and tightly closed.
Use only in well ventilated areas. Keep away from oxidizers, incompatible materials, heat, and other ignition sources. There
should be no source for accidental ignition in work and storage areas. Immediately close containers after use. Use non-
sparking tools. Five-gallon and larger containers should be grounded and/or bonded before pouring or otherwise
transferring material. Cement may become electrostatically charged during mixing, filtering or pumping at high flow rates.
Sufficient charges may cause sparks that can ignite vapors. Sudden release of hot organic mists or vapors from process
equipment operating at elevated temperature and pressure or sudden entry of air into vacuum equipment may cause ignition
without presence of obvious ignition sources. Evaluate all elevated temperature processes thoroughly to maintain safe
operating conditions.
Empty containers may contain flammable product residue and vapors and should be handled and stored appropriately. Do
not heat, cut, or weld on or near empty containers. Do not re-use containers unless properly cleaned and re-conditioned.
Wear appropriate protective equipment. Use proper handling procedures for any ingredients added to this product.
Avoid skin and eye contact. Do not inhale. Intentional concentration and inhalation of vapors can be harmful or fatal. Do
not eat, drink, smoke, or apply cosmetics in work areas. Do not store personal items in work areas. Wash hands before
eating, drinking, smoking, and breaks.
8. EXPOSURE CONTROLS/PERSONAL PROTECTION
RESPIRATORY PROTECTION: Under normal working conditions below acceptable exposure guidelines, none required.
Respiratory protection is dependent upon conditions and magnitude of exposure. Select NIOSH-approved respirators in
accordance with 29 CFR 1910.134.
SKIN PROTECTION: Protective polyvinyl alcohol gloves worn with additional protective clothing (boots, apron, etc.) as
necessary to prevent irritation.
EYE PROTECTION: Protective goggles. Full-facepiece supplied air respirator for high concentrations.
ENGINEERING CONTROLS: General ventilation used in combination with local exhaust and enclosed processes as
necessary to control air contaminants to at or below acceptable exposure guidelines.

11. TOXICOLOGICAL INFORMATION
INHALATION: High concentrations of solvents can cause respiratory irritation and CNS depression. An L50 of 6,350 ppm/4
H has been cited for xylene (rat). Inhalation of 9150 ppm ethylbenzene caused death in 2 hours in mice.
SKIN: Repeated or prolonged contact may dry or defat the skin causing cracks and secondary infection. Sensitive
individuals may develop dermatitis with repeated contact.
EYE: Ethylbenzene causes severe eye irritation at 2000 ppm and irritation becomes intolerable at 5000 ppm. Xylene
causes less severe irritation (specific values were unavailable).
CHRONIC: Ethylbenzene has caused cancer in laboratory animals and is classified as a possible human carcinogen by
IARC. In a 2-year ethylbenzene inhalation study (6 H/day; 5 days/week for 104 weeks), there was clear evidence of
carcinogenic activity of ethylbenzene in male F344/N rats that inhaled 750 ppm ethyl benzene and some evidence of
carcinogenic activity in female rats and in male and female B6C3F1 mice (at 750 ppm).
Rubber contains carbon black. Although release of these ingredients is not expected, repeated inhalation of carbon black
can affect the lungs and may increase risks of developing cancer.
OTHER: Studies indicate that toluene may increase the risk of miscarriage and adversely affect fetal development.
Ethylbenzene and xylene have caused birth defects at high concentrations in experimental animals; however studies are
inconclusive.
12. ECOLOGICAL INFORMATION
Does not contain Class I or II ozone depleting substances. Ecotoxic effects are expected to resemble those seen in humans
and test animals.
