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.

4. First Aid Measures

Inhalation: Remove to fresh air. Rinse mouth to clear throat and expel liquid. Blow nose to evacuate dust. Consult a physician if irritation persists.

Eye Contact: Products can be physical irritants to eyes. Do not rub eyes. Keep hands or contaminated body parts away from eyes. Remove contact lenses. Flush with water. If irritation persists, consult a physician.

Skin Contact: Products are irritants. Wash with soap and water. For dryness, a skin cream may be helpful. Do not apply anything to a rash. Consult a physician if irritation persists.

Ingestion: Drink plenty of water. Do not induce vomiting without advice of a physician. Seek medical attention.

5. Fire Fighting Measures

Materials are not combustible.

6. Accidental Release Measures

Spill Procedures: Clean up procedures should minimize formation of airborne dusts. Remove dust by vacuuming using HEPA filtration where possible. or use wet sweeping or a dust suppressant where sweeping is necessary.

Release into Air: Prevent release of airborne particulates where possible.

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 in a dry place indefinitely. Physical abrasion may produce small amounts of respirable dusts. Minimize airborne dusts by avoiding the unnecessary disturbance of materials

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 fibers or particulates. While not considered problematic during use, airborne fibers may complicate removal activities. It is recommended that product use be carefully matched to design parameters.

After Service: The fibers used in Soluble Fiber Insulation may devitrify and form cristobalite (a form of crystalline silica) when used at temperatures above 1000°C for extended 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 crystobalite from occupational sources is carcinogenic to humans (Group 1)." OSHA has adopted a permissible exposure limit (PEL) for respirable crystobalite at 0.05 mg/m³. Appropriate ventilation and respiratory protection should be provided in compliance with OSHA standards. Strict adherence to recommended safe work practices is advised. Product removal must consider the possibility of usage above design temperatures. See section 8 for appropriate respiratory protection during removal.

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 < 1.0 f/cc	No specific recommendation, use personal protective equipment based on local conditions.
PPE 1.0 f/cc to 5.0 f/cc	Half-face, air purifying respirator equipped with a high efficiency particulate air (HEPA) filter cartridge.
PPE 5.0 to 25 f/cc	Full-facepiece, air purifying respirator equipped with a high-efficiency particulate air (HEPA) filter cartridge
PPE > 25 f/cc	Full-facepiece, positive pressure, supplied air respirator.
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. See section 7 for after service and section 13 for disposal recommendations.

10. Stability and Reactivity

Conditions or materials to avoid: Avoid direct contact with strong acid environments.

Decomposition Products: Fibers contained in this product may form cristobalite when used at temperatures above 1000C for sustained periods of time. See section 7 for more information.

11. Toxicology

Epidemiology: The fibers used in these insulation products have not been the subject of epidemiological studies. Epidemiological studies related to other fiber chemistries of similar solubility have not identified a stastically significant incidence of exposure-related respiratory disease.

Toxicology: The dissolution rate of the fibers used in Soluble Insulation Products has been determined through standard in vitro testing. The dissolution rate of these fibers is higher than that of other fiber types that have been tested in chronic animal studies and did not produce respiratory disease. These fibers possess a fiber chemistry within the regulatory (European Commission Directive 97/69/EC) definition as a "man-made vitreous (silicate) fiber with random orientation with alkaline oxide and alkaline earth oxide (Na₂O + K₂O + MgO + BaO) content greater than 18% by weight". These fibers have been tested pursuant to EU protocal ECB/TM/27, rev.7, Nota Q, Directive 97/69/EC. The test results were below regulatory; hence, the product is no longer subject to EU classification.

12. Ecological Information

Ecotoxicological Information: No ecological concerns have been identified.

.13. Disposal Information

Disposal: Consult with local, state and federal regulations. In most cases these materials may be landfilled safely. Disposal regulations vary. Consult with all applicable regulations prior to disposal.

14. Transportation Information

Not regulated hazardous substances, no specific regulations apply.
