SECTION IV - FIRE & EXPLOSION DATA
FLASH POINT (Method Used): 480篎 (PMCC)
FLAMMABLE LIMITS: N/DA
AUTOIGNITION TEMPERATURE: N/DA
EXTINGUISHING MEDIA: Use water fog, foam, dry chemical, or CO2.
SPECIAL FIRE FIGHTING PROCEDURES: Material will not burn unless preheated. Do not enter confined
space without full bunker gear (helmet with face shield, bunker coats, gloves and rubber boots), including a
positive pressure NIOSH approved self-contained breathing apparatus (SCBA). Cool fire exposed containers
with water.
UNUSUAL FIRE & EXPLOSION HAZARDS: See Section VII.
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 animals 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)
ACUTE TOXICITY DATA:
Acute Oral LD50 Acute Dermal LD50 Acute Inhalation LC50
11.4 g/kg (rat) >20 ml/kg (rabbit) No deaths in saturated air, 8 hr.
15.6 g/kg (mouse)
PRIMARY ROUTE OF ENTRY- Inhalation.
CHEMICAL LISTED AS CARCINOGEN OR POTENTIAL CARCINOGEN: None
NTP: No IARC: No OSHA: No
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. Contact with product at elevated temperatures can result in thermal
burns.
SKIN- Mildly irritating. Based on product testing product may cause skin sensitization. Contact with
product at elevated temperatures can result in thermal burns.
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- Base on product testing, product is considered to have a low order of acute oral toxicity.
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. Preexisting skin and eye disorders may be aggravated by exposure to this product. Preexisting
skin or lung allergies may increase the chance of developing increased allergy symptoms form exposure to
this product.
SECTION VI - EMERGENCY & FIRST AID PROCEDURES
EYE CONTACT: Immediately rinse with clean water for 15 minutes. Retract eyelids often. Get medical
attention. If contact with hot product occurs immediately flush with cool water for 15 minutes. Get
medical attention immediately.
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.
If contact with hot product occurs immediately flush with cool water for 15 minutes. Carefully remove
clothing; if clothing is stuck to a burn area do not pull it off, but cut around it. Cover burn area with a clean
material. Get medical attention immediately.
INHALATION: If overcome by exposure, remove victim to fresh air. Provide oxygen if breathing is difficult.
Get medical attention.
INGESTION: Do not induce vomiting. In general, no treatment is necessary unless large quantities of
product are ingested. However, get medical advice.
NOTE TO PHYSICIA: In general, emesis induction is unnecessary in high viscosity, low volatility products,
e.g., neat epoxy resins.

SECTION VII - REACTIVITY DATA
STABILITY: Stable.
MATERIALS TO AVOID- Avoid alteration of product properties before reuse. Calcining, which may result
in crystalline formation or mixing with additives may alter toxicological properties. Can react vigorously
with strong oxidizing agents, strong Lewis or mineral acids, and strong mineral and organic bases/especially
primary and secondary aliphatic amines.
CONDITIONS TO AVOID- Avoid high temperatures (>800?C) treatment. Reaction with some curing
agents may produce considerable heat. Run-a-way cure reactions may char and decompose the resin
system, generating unidentified fumes and vapors which may be toxic.
HAZARDOUS DECOMPOSITION PRODUCTS: Oxides of carbon when burned, aldehydes, acids, and other
organic substances may be formed during combustion or elevated (>500?F) temperature degradation.
HAZARDOUS POLYMERIZATION: Will not occur.
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 - SPECIAL PROTECTION INFORMATION
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.
