moderate skin irritant; skin sensitizer; slight ingestion hazard.
Chronic Health Effects: (See Section 11.)
HMIS: 2-1-1
CAUTION: Dust may be irritating to eyes and upper respiratory tract. Prolonged or repeated skin contact may
cause irritation due to drying action.
Precautions: Avoid contact with eyes. Avoid prolonged or repeated contact with skin. Avoid prolonged,
repeated or excessive inhalation. Use only with adequate ventilation. Ventilation must be sufficient to limit
employee exposure to this product below permissible exposure limits. Wear respiratory protection when dust
exposure is above permissible exposure limits. Wash thoroughly every day after work. Do not eat, drink or smoke
in work area.
4. FIRST AID MEASURES
INHALATION: Remove from area to fresh air. Get medical attention if respiratory irritation develops or if
breathing becomes difficult. If symptomatic, contact a poison control center, emergency room or physician for
treatment information.
EYE CONTACT: Remove contact lens and pour a gentle stream of warm water through the affected eye for at
least 15 minutes. Retract eyelids often. If irritation persists, contact a poison control center, emergency room or
physician as further treatment may be necessary.
SKIN CONTACT: Remove contaminated clothing. Run a gentle stream of water over the affected area for 15
minutes. A mild soap may be used if available. If any symptoms persist, contact a poison control center,
emergency room or physician as further treatment may be necessary.
INGESTION: If a large quantity is swallowed, give lukewarm water (a pint) if the victim is completely conscious
and alert. Do not induce vomiting or risk of damage to lungs may exceed the risk of poisoning. Contact a poison
control center, emergency room or physician for treatment information.

5. FIRE FIGHTING MEASURES
FLASH POINT: 93C (200F) PMCC
EXTINGUISHING MEDIA: Dry chemical, CO2, foam, water spray/water fog for cooling.
SPECIAL FIREFIGHTING PROCEDURES: Spontaneous polymerization reaction may be caused by high
temperatures, inhibitor depletion, accidental impurities, or exposure to radiation or oxidizers. Do not enter fire
area withough proper protection. Water may be ineffective in firefighting due to ow solubility. Use water spray/fog
for cooling. Do not allow material to enter sewer or public waters.
6. ACCIDENTAL RELEASE MEASURES
Spilled or released material may polymerize and release heat and gasses. Extinguish all ignition sources and
ventilate the area. Wear protective equipment during clean-up. Dike and recover large spills. Wash the spill area
with a strong detergent and water solution; rinse with water but minimize water during cleanup. Dispose per
regulatory requirements. See Section 13 for disposal information.
7. HANDLING AND STORAGE
Store in a dry area. Wear appropriate protective equipment when handling this material. See Section 8. Product
may be heated to 60C (140F) for not more than 24 hours. Do not use localized heat sources. Do not use steam.
Use a hot box or hot room set to a maximum temperature of 60C (140F). Do not overheat or compromise of
product quality may occur. Do not overheat or uncontrolled, hazardous polymerization may occur. If product
freezes, heat as indicated above. Product should be consumed in its entirety after heating. Avoid multiple "re-
heats" which may affect quality or result in degradation. Product is packaged with inhibitor(s). Unless inhibited,
the product can polymerize, raising temperature and pressure and possibly rupturing the container. Check
inhibitor content periodically, adding if needed. In addition, inhibitors require the presence of dissolved oxygen.
Maintain at least the original headspace in the container and do not blanker or mix with oxygen-free gas as this
renders the inhibitor ineffective. Ensure air space (oxygen) is present during product heating.
Store indoors at temperatures greater than 0C (32F) and below 38C (100F). Avoid prolonged storage longer that
shelf-life. Store in tightly closed containers in a properly vented storage area way from heat, sparks, open flame,
strong oxidizers, radiation, and other initiators. Prevent contamination by foreign materials. Prevent moisture
contact. Use only non-sparking tools and limit storage time. Unless specified elsewhere, shelf-life is 6 months
from date of manufacture printed on the label. When transferring material use proper grounding to avoid
electrical sparks. Surface alterations caused by calcining or mixing with additives may alter toxicological
properties.
8. EXPOSURE CONTROLS/PERSONAL PROTECTION
A PEL or TLV has not been established for the acrylate portion of this product. The following information is
available for the silica portion of this product.
Exposure Limits: 8-hour Time Weighted Average (TWA); 15-minute Short-Term Exposure Limit (STEL)
OSHA: 6 mg/m3 (total dust) TWA.
ACGIH: 10 mg/m3 (total amorphous dust) TWA. 3 mg/m3 (respirable nuisance particulate) TWA.
RESPIRATORY PROTECTION: Use NIOSH approve dust filter respirator for exposure above permissible
exposure limits. The respiratory use limitations made by NIOSH or the manufacturer must be observed.
VENTILATION: General or local exhaust sufficient to maintain employee exposure below permissible exposure
limits.
EYE AND FACE PROTECTION: If eye exposure to powder is likely, use tight fitting protective goggles. Contact
lenses should not be worn.
PROTECTIVE GLOVES: Cloth, leather or rubber.
OTHER PROTECTIVE EQUIPMENT: Boots, aprons, or chemical suits should be used when necessary to
prevent skin contact. This equipment must be cledaned thoroughly after each use.

additives and alteration of product properties may alter toxicological properties.
HAZARDOUS THERMAL DECOMPOSITION/COMBUSTION PRODUCTS:
Acrid smoke and fumes, carbon monoxide, carbon dioxide and other toxic vapors may be released during a fire
involving this product.
11. TOXICOLOGICAL INFORMATION
SKIN IRRITATION: Extensive / prolonged or repeated exposure to this material can result in significant
absorption. Moderate skin irritant and an allergic sensitizer. Symptoms of irritation may include redness or rash,
swelling of the affected area and blistering. Prolonged skin contact may result in a more severe sking response.
Symptoms may be delayed.
EYE IRRITATION: May cause eye irritation. Symptoms may include burning sensation, tearing, redness or
swelling.
CARCINOGENICITY: Chronic Health Effects: The active ingredient in this material, SR206, was tested positive
for mutagenicity in the mouse lymphoma assay but negative in the Ames test. There is reason to believe that the
mouse lymphoma assay was a false positive finding. It should be noted that this assay system produces a high
incidence of false responses.
EFFECTS OF OVEREXPOSURE:
ACUTE: Excessive contact with powder can cause drying of mucous membranes of nose, eyes, and throat due
to absorption of moisture and oils. This material can also cause nasal irritation and nosebleeds. Eye contact with
powder can result in mild irritation.
CHRONIC: An epidemiological study was conducted which included 165 precipitated silica workers who had
been exposed an average time span of 8.6 years. Of these 165 workers, 44 had bee exposed for an average of
18 years. No adverse effects were noted in complete medical examinations (including chest roentgenograms) of
these workers. Pulmonary function decrements were correlated only with smoking and age but not with the
degree of duration of dust exposures. Laboratory studies have also been conducted in small animals via
inhalation to levels of precipitated silica dust of up to 126 mg/m3 per 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 the studies performed by, or known to, PPG indicate
a very low order of pulmonary activity for synthetic precipitated silica. PPG recommends that 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.
IARC reviewed the data on amorphous silica in 1996 and concluded there was inadequate evidence from both
epidemiology and experimental studies that amorphous silica is a carcinogenic risk factor. The organization
concluded that amorphous silica is in Group 3.
