3. HAZARDS IDENTIFICATION
Eye Contact: May cause eye irritation.
Skin Contact: Slight mechanical irritation is possible.
Inhalation: Inhalation of dust may cause respiratory tract (nose, throat, lungs) irritation.
4. FIRST AID MEASURES
RESPIRATORY TRACT (nose & throat) IRRITATION:
1
If respiratory tract irritation develops, move the person to a dust free location. Get medical attention if the irritation
continues.
EYE IRRITATION:
If eyes become irritated, flush immediately with large amounts of lukewarm water for at least 15 minutes. Eyelids
should be held away from the eyeball to ensure thorough rinsing. Do not rub eyes. Get medical attention if irritation
persists.
SKIN IRRITATION:
Wash area of contact thoroughly with soap and water. Do not rub or scratch exposed skin. Using a skin cream or
lotion after washing may be helpful.
GASTROINTESTINAL IRRITATION:
If gastrointestinal tract irritation develops, move the person to a dust free environment.
5. FIRE FIGHTING MEASURES
This product is non-combustible (does not burn).
6. ACCIDENTAL RELEASE MEASURES
Avoid creating airborne dust. Dust suppressing cleaning methods such as wet sweeping or vacuuming should be
used to clean the work area. If vacuuming, the vacuum must be equipped with a HEPA filter. Compressed air or dry
sweeping should not be used for cleaning.
7. HANDLING AND STORAGE
STORAGE
Store in a dry area.
HANDLING
Limit use of power tools unless in conjunction with local exhaust. Use hand tools whenever possible. Frequently
clean the work area with HEPA filtered vacuum or wet sweeping to minimize the accumulation of debris. Do not use
compressed air for clean-up.
8. EXPOSURE CONTROLS/PERSONAL PROTECTION
ENGINEERING CONTROLS
Use engineering controls such as local exhaust ventilation, point of generation dust collection, down draft work
stations, emission controlling tool designs, and materials handling equipment designed to minimize airborne
particulate.
Respiratory Protection:
In case of dust formation, use a NIOSH approved respirator for nuisance dust.

Skin Protection:
Wear gloves, head coverings and full body clothing as necessary to prevent skin irritation. Barrier cream may be
useful to prevent dryness of skin.
Eye Protection:
In case of dust formation, wear safety glasses with side shields or other forms of eye protection in compliance with
appropriate OSHA standards to prevent eye irritation. Do not touch eyes with soiled body parts or materials. If
possible, have eye-washing facilities readily available where eye irritation can occur.

HAZARDOUS DECOMPOSITION PRODUCTS:
Excelfrax® 1800 Board & Excelfrax® 300 VIP
At combustion, silicon carbide, silica, carbon dioxide, carbon monoxide, incompletely burnt hydrocarbons (in
traces) may be formed. Use adequate ventilation or other precautions to eliminate exposure to vapors resulting
from thermal decomposition.
Excelfrax® 1800 Flexliner (encapsulated)
At combustion, zirconium compounds, aluminum oxide, silica, carbon dioxide, carbon monoxide, incompletely
burnt hydrocarbons (in traces) may be formed. Use adequate ventilation or other precautions to eliminate
exposure to vapors resulting from thermal decomposition.
HAZARDOUS POLYMERIZATION: Not Applicable.
11. TOXICOLOGICAL INFORMATION
The International Agency for Research on Cancer (IARC), has concluded that amorphous silica is "not classifiable as
to its carcinogenicity to humans (Group 3)" based on "inadequate evidence in humans for the carcinogenicity of
amorphous silica" and "inadequate evidence in experimental animals for the carcinogenicity of synthetic amorphous
silica" (IARC Monograph 68, June 1997, p. 210-211).
EPIDEMIOLOGY:
IARC noted that "very little epidemiological evidence was available" for amorphous silica. In evaluating the results of
three community-based case-control studies, IARC concluded that "no association was detected for mesothelioma
TOXICOLOGY:
A food-grade miconized synthetic amorphous silica was tested by oral administration to mice and rats. No increased
incidence of tumors was seen. In another study in rats, using intrapleural implantation of two different preparations of
synthetic amorphous silica, no increased incidence of tumors were observed (IARC Monograph 68, June 1997, p.
209).
Excelfrax® 1800 Board & Excelfrax® 1800 Flexliner contain fibrous glass (continuous filament). In case of
dust formation, exposure to these fibers may occur. The fibers are not respirable, i.e. can not enter the lungs, due to
their >3 micron length to diameter ratio. Glass filaments have been classified by IARC as not classifiable as to their
carcinogenicity to humans (Group 3).

15. REGULATORY INFORMATION
EPA: Toxic Substances Control Act (TSCA) - All substances in this product are listed, as required,
on the TSCA inventory.

and the Respiratory Protection Standards 29 CFR 1910.134 and 29 CFR 1926.103.
16. OTHER INFORMATION
Formation of crystalline silica (cristobalite) is possible after prolonged use (> 900 degrees C). IARC’s evaluation of
crystalline silica states “Crystalline silica inhaled in the form of quartz or cristobalite from occupational sources is
carcinogenic to humans (Group 1)� and additionally notes “carcinogenicity in humans was not detected in all industrial
circumstances studied� (IARC Monograph Vol. 68, 1997). NTP lists all polymorphs of crystalline silica amongst
substances which may "reasonably be anticipated to be carcinogens".
