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:
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.

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 with biogenic amorphous silica fibres." (IARC Monograph 68, June 1997, p. 208).


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).

12. ECOLOGICAL INFORMATION

No ecological concerns have been identified.
13. DISPOSAL CONSIDERATIONS

Formation of crystalline silica (cristobalite) is possible after prolonged use (> 900°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".
