SECTION IV - FIRE & EXPLOSION DATA
FLASH POINT (Method Used): N/E (Expected to be >200掳 F)
FLAMMABLE LIMITS: N/E
AUTOIGNITION TEMPERATURE: N/E
EXTINGUISHING MEDIA: Water, ABC dry chemical, or Protein type air foams are recommended media.
Elastomers would be considered "ordinary combustibles" (NFPA defined Class A). Carbon dioxide is generally
not recommended for use on Class A fires as a lack of cooling capacity may result in re-ignition.
SPECIAL FIRE FIGHTING PROCEDURES: Wear positive pressure self-contained breathing apparatus (SCBA)
during the attack phase of firefighting operations and during cleanup in enclosed or poorly ventilated areas
immediately after a fire. Personnel not having suitable respiratory protection must leave the area to prevent
significant exposure to toxic combustion gases from any source.
UNUSUAL FIRE & EXPLOSION HAZARDS: Closed containers may rupture due to pressure buildup under fire
conditions. Toxic gases may be formed upon combustion and represents a hazard to firefighters. See Section
VII for additional information on combustion products.
SECTION V - HEALTH HAZARD DATA
CHRONIC HEALTH EFFECTS: An epidemiological study was conducted which included 165 precipitated silica
workers who had been exposed for an average of 18 years. No adverse effects were noted in complete medical
examination (including chest roentgenograms) of these workers. Pulmonary function decrements were correlated
only with smoking and age but not with the degree or duration of dust exposure. Laboratory studies have also
been conducted in small animals via inhalation to levels of precipitated silica dust of up to 126 mg/m3 for periods
from six months to two years. Although precipitated silica was temporarily deposited in the animal's lungs, most
of the deposited material was cleared soon after the dust exposure ended. The results of all studies performed
by, or known to, PPG indicate a very low order of pulmonary activity for synthetic precipitated silica.

SECTION V - HEALTH HAZARD DATA (cont
PRIMARY ROUTE OF ENTRY- Inhalation, skin, eye contact and process vapor inhalation.
CHEMICAL LISTED AS CARCINOGEN OR POTENTIAL CARCINOGEN: See Appendix.
NTP: No IARC: No OSHA: No
POTENTIAL HEALTH EFFECTS FROM OVEREXPOSURE:
No adverse effects are expected during normal processing when potential exposures are eliminated by good
industrial hygiene practice and well ventilated conditions. At processing temperatures, the combined ingredients
(elastomer and other processing ingredients) may emit fumes and vapors that may cause irritation to the eyes,
skin, nose, throat, and respiratory tract. Processing under conditions of inadequate ventilation may produce
symptoms nausea, dizziness, or headaches. Typically these effects are reversible upon removal from exposure
and no lasting effects are expected. Most importantly, the potential for irritation will depend on the effectiveness
of exhaust ventilation provided to the process area.
Nipol1312 contains a trace amount of p-t-butyl phenol as a component of the antioxidant package. Although
rare, there are reports of pigmentation of the skin (vitiligo) associated with this compound in related elastomer
products. We recommend that contact with exposed skin be avoided by the use of gloves and other personal
protective equipment appropriate for handling and/or processing.
Overexposure to decomposition or combustion products may cause irritation of the eyes, skin, and respiratory
tract. Symptoms such as coughing, tearing, and irritation should be regarded as potentially hazardous and
measures taken to avoid exposure.
EFFECTS OF EXPOSURE-
EYES- Mildly irritating. Excessive contact with powder can cause drying of mucous membranes of eyes due to
absorption of moisture and oils.
SKIN- Mildly irritating.
INHALATION- Nuisance dust. Excessive contact with powder can cause drying of mucous membranes of nose
and throat due to absorption of moisture and oils. This material can also cause nasal irritation and nosebleeds.
INGESTION- Not significantly toxic.
MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE- Persons with breathing problems or lung disease
should not work in dusty areas unless a physician approves and certifies their fitness to wear respiratory
protection.
SECTION VI - EMERGENCY & FIRST AID PROCEDURES
EYE CONTACT: Immediately rinse with clean water for 15 minutes. Retract eyelids often. If irritation persists,
seek medical attention.
SKIN CONTACT: Immediately remove contaminated clothing. Wash skin thoroughly with mild soap and water.
Flush with lukewarm water for 15 minutes. Seek medical attention if ill effect or irritation develops.
INHALATION: If overcome by exposure, remove victim to fresh air. If breathing has stopped, administer artificial
respiration and seek medical assistance immediately.
INGESTION: N/DA

SECTION VII - REACTIVITYDATA
STABILITY: Stable.
MATERIALS TO AVOID- Avoid alteration of product properties before reuse. Avoid or mixing with additives that
may alter toxicological properties, such as strong oxidizers and reducing agents.
CONDITIONS TO AVOID- Avoid overheating. Avoid calcining (temperatures >800掳C) which may result in
crystalline silica formation.
HAZARDOUS DECOMPOSITION PRODUCTS: Oxides of carbon when burned.
HAZARDOUS POLYMERIZATION: Fumes produced when heated to decomposition temperatures may contain
oxides of carbon, hydrogen cyanide, oxides of nitrogen, and small amounts of aromatic and aliphatic
hydrocarbons. Combustion products from rubber, like those of other natural and synthetic materials, must be
considered toxic.
SECTION VIII - SPILL OR LEAK PROCEDURES
STEPS TO BE TAKEN IN CASE MATERIAL IS RELEASED OR SPILLED: MINIMIZE SPILL AREA. Vacuum
spill material and place in closed plastic bags for disposal.
WASTE DISPOSAL METHOD: In accordance with local, state, and federal regulations.
SECTION IX - SPECIALPROTECTIONINFORMATION
RESPIRATORY PROTECTION: Use a respirator such as 3M 9900 or equivalent for protection against
pneumoconiosis producing dusts.
VENTILATION: Provide explosion proof ventilation as required to control airborne dust levels. The sum total of
all ingredients may emit vapors during normal processing. All possible health effects are not known and individual
sensitivities will vary. Effective exhaust ventilation should always be provided to draw dust, fumes and vapors
away from workers to prevent routine inhalation. Ventilation should be adequate to maintain ambient workplace
atmosphere below the limits listed in Section V.
PROTECTIVE GLOVES: Impervious gloves to protect against contact with product.
EYE PROTECTION: Safety goggles.
OTHER PROTECTIVE EQUIPMENT: Protective clothing, eye wash station, safety shower.
SECTION X - SPECIAL PRECAUTIONS
HANDLING AND STORAGE: Handling can create explosive dust clouds. Eliminate ignition sources, use
explosive proof equipment. Conveying and processing equipment should be spark-proof, well bonded and
grounded. Avoid dust accumulations.
OTHER PRECAUTIONS: Wash with soap and water before eating, drinking, smoking, or using toilet facilities.
Launder contaminated clothing before reuse.

SECTION XII - OTHER INFORMATION
Appendix A - Acrylonitrile
This product contains trace amounts of acrylonitrile. Acrylonitrile is regulated by OSHA at 29 CFR 1910.1045.
Acrylonitrile is listed by OSHA as a carcinogen, by IARC as a Group 2A carcinogen, by NTP as an anticipated
human carcinogen, and by ACGIH as a suspected human carcinogen. Air sampling studies conducted on related
acrylonitrile/butadiene polymers under simulated compound processing conditions showed airborne concentration
of acrylonitrile to be below one (1) ppm. Users should not rely on manufacturer's data alone, but should do
sufficient in-plant testing for acrylonitrile levels to assure compliance of their operations.
Appendix B - Butadiene
This product contains trace amounts of butadiene. Butadiene is regulated by OSHA at 29 CFR 1910.1051.
Butadiene is listed by the IARC as a Group 2A carcinogen, by NTP as an anticipated human carcinogen, and by
ACGIH as a suspected human carcinogen.
Appendix C - 4-Vinyl Cyclohexane
This product contains trace amounts of 4-Vinyl Cyclohexane. 4-VCH is listed by the IARC as a Group 2B
carcinogen and by ACGIH as an animal carcinogen.
