3. Hazard Identification

Emergency Overview

TARGET ORGANS: Skin, eyes, and lungs

CAUTION: Handling or machining of these products may produce respirable dust particles. Dust may irritate eyes, skin respiratory tract.

Inhalation

Dust may cause irritation or soreness of throat and nose.

Eye Contact

Dust may cause temporary irritation or inflammation.

Skin Contact

May cause temporary dryness, irritation or rash.

Ingestion

Ingestion is unlikely. May cause gastrointestinal disturbances. Never induce vomiting without the advice of a physician.

Medical Conditions Aggravated by Exposure: Respiratory effects may be aggravated by smoking. Pre-existing respiratory problems may be aggravated by dust. Removal of used product, sanding, scraping, or otherwise destroying the integrity of the dried product may result in the release of silica dust. Pre-existing medical conditions, including dermatitis, asthma or chronic lung disease may be aggravated by exposure to silica dust; individuals who are atopic (with a history of allergies) may experience greater amounts of skin and respiratory irritation.

Hazard Classification: The International Agency for Research on Cancer (IARC) has determined that amorphous silica is not classifiable as to its carcinogenicity to humans (Group 3). IARC classified respirable crystalline silica, a possible byproduct of amorphous silica devitrification following sustained, high-temperature (>1800F) use, as a substance known to be carcinogenic to humans (Group 1).

6. Accidental Release Measures

Spill Procedures: Contain with absorbent material, such as clay, soil or any commercially available absorbent. Shovel reclaimed liquid and absorbent into recovery or salvage drums for disposal. Clean up procedures should minimize formation of airborne dusts. Remove dust by vacuuming using HEPA filtration where possible. Liquid products (groups 1) should be cleaned up with sponge, mop or cloth.

Large liquid spills: Dike to prevent further movement and reclaim into recovery or salvage drums or tank truck for disposal.

Release into Air: Prevent release of airborne particulates where possible. Not a regulated hazardous substance. See section 8 for appropriate engineering controls.

Release into Water: Release into water is not appropriate. Not a regulated hazardous substance. Landfill dusts and debris consistent with local regulations.

7. Handling and Storage

Storage: These materials are stable and may be stored indefinitely. Physical abrasion may produce small amounts of respirable dusts. Liquid products (group 1) should be stored in a sealed container. See precautions under section 8.

Normal Use: Materials are stable under normal use and are not expected to produce significant hazardous by-products or emissions.

Machining and Cutting: These materials may produce respirable and nuisance dusts when machined or cut. See section 8 for exposure controls and personal protection during machining or installation procedures.

High Temperature Conditions: Service significantly above the product design temperature may increase friability and the possibility of generating airborne particulates. While not considered problematic during use, airborne particulates may complicate removal activities. It is recommended that product use be carefully matched to design parameters.

After Service: As manufactured these products may contain amorphous silica which may transform upon heating (temperatures greater than 1000oc for extended periods of time) to cristobalite (CAS # 14464-46-1), a form of crystalline silica. Removal of these products after use may generate dusts. Prolonged or repeated inhalation of respirable free crystalline silica dust may cause delayed lung injury (silicosis). The IARC has classified crystalline silica as group 2A, probable human carcinogen. There is sufficient evidence of carcinogenicity in animals, but limited evidence in humans. OSHA's final rule limit and ACGIH'S tlv for respirable cristobalite is .05 mg/m3 . Product removal must consider the possibility of usage above design temperatures. See section 8 for appropriate respiratory protection during removal.

Empty Containers: Product packaging may contain residue. Do not reuse.


8. Exposure Controls

Engineering Controls:

Use dust suppression controls. Local exhaust ventilation, point of generation dust collection, and/or down-draft work stations to minimize airborne dust generation are recommended when machining product.

Respiratory Protection:

Use appropriate protection pursuant to OSHA 29CFR 1910.134 and 29CFR 1926.103. The following information is provided as a guide and reflects industry recommendations for control of dust.

PPE Other

Work clothes should be washed separately and the washing machine rinsed following use. If possible, do not take work clothes home following machining or removal activities that produce significant amounts of dust.

Skin Protection

Wear gloves, head coverings, and full body clothing to prevent skin irritation. Disposable clothing may be used. Store work clothes and street clothes separately.

Eye Protection

Wear safety glasses or chemical goggles to prevent eye contact. Do not wear contact lenses without goggles. Do not get dust or liquids into eyes. Have eye washing facilities available when using products.

These products are generally not hazardous during normal use. These guidelines are provided for special circumstances involved in machining , use and or after service removals.

11. Toxicology

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).
12. Ecological Information

Ecotoxicological Information: No information available.

Distribution: Silica is naturally occurring and widely distributed in igneous rock. Secondary deposits in sedimentary rock may be found.

16. Other

After-Service: Removal

The amorphous silica contained in this product may devitrify and form cristobalite (a form of crystalline silica) when used at temperatures above 1000C for sustained periods. Chronic exposure to respirable crystalline silica may lead to lung disease. IARC has concluded that: "Crystalline silica inhaled in the form of quartz or cristobalite from occupational sources is carcinogenic to humans (Group 1)." [IARC Monograph 68, June 1997, p. 210-211]. The Occupational Safety and Health Administration (OSHA) has adopted a permissible exposure limit (PEL) for respirable cristobalite at 0.05 mg/m. When needed, the use of proper exposure controls and respiratory protection is recommended to reduce potential health risks and to ensure compliance with OSHA requirements. The evaluation of workplace hazards and the identification of appropriate respiratory protection is best performed, on a cases by case basis, by a qualified Industrial Hygienist.
