OSHA A. EMERGENCY OVERVIEW:

Appearance/Odor

translucent solid, odorless Warning Statements Based on currently available data, this product does not meet the regulatory definition of a hazardous substance. However, good industrial hygiene practices should be used in handling it.

Potential health effects

Acute Eye: Slightly irritating. May cause redness, irritation. Acute Skin: Non-irritating. Acute Inhalation: Inhalation not likely. Acute Ingestion: Practically non-toxic.

Potential chronic health

This product does not contain any ingredient designated by IARC, NTP, ACGIH or OSHA as probable or suspected human carcinogens. 4. FIRST AID MEASURES FIRST AID MEASURES FOR ACCIDENTAL: Eye Exposure: In case of contact, immediately absorb excess with clean absorbent cloth or cotton. Then, hold eyelids open and flush with a steady, gentle stream of water for at least 15 minutes. Seek medical attention if irritation develops or persists or if visual changes occur. Skin Exposure: Immediately wipe excess material off skin with a dry cloth; then wash skin with plenty of soap and water. Seek medical attention if irritation develops or persists. Inhalation: Inhalation is not an expected route of exposure. If respiratory irritation or distress occurs remove victim to fresh air. Seek medical attention if respiratory irritation or distress continues. Ingestion: Do Not induce vomiting. Rins mouth thoroughly. Get medical attention if systems occur. MEDICAL CONDITIONS POSSIBLY AGGRAVATED BY EXPOSURE: No specific information found. NOTES TO PHYSICIAN: All treatments should be based on observed signs and symptoms of distress in the patient. Consideration should be given to the possibility that overexposure to materials other than this product may have occurred. Treat symptomatically. No specific antidote available. 5. FIRE FIGHTING MEASURES FIRE HAZARD DATA: Extinguishing Media: Recommended: dry chemical, foam, carbon dioxide, water fog. Unsuitable extinguishing media: Do not use water jet as an extinguisher, as this will spread the fire. Protective Measures: Firefighters should wear NIOSH/MSHA approved self-contained breathing apparatus and full protective clothing. Cool containers exposed to fire with water. Unusual Fire and Explosion Hazards: Product will burn under fire conditions. Hazardous Decomposition Materials: formaldehyde, oxides of carbon, silica (crystalline). Special fire fighting procedures: No specific recommendations. 6. ACCIDENTAL RELEASE MEASURES Evacuation Procedures and Safety: Wear appropriate protective gear for the situation. See Personal Protection information in Section 8. CAUTION: Spilled material may make the floor slippery. Do not leave traces of product on floors, ladders, etc., as this may present a slipping hazard. Containment of Spill: Follow procedure described below under Cleanup and Disposal of Spill. Cleanup and Disposal of Spill: Absorb with an inert absorbent. Scrape up and place in appropriate closed container. Clean up residual material with an appropriate solvent like paint thinner or mineral spirits, provided that there is good ventilation and no sources of ignition. Environmental precautions: Do not allow to enter drains, sewers or watercourses. 7. HANDLING AND STORAGE Minimum/Maximum Storage Temperatures: Temperatures not available. Store in tightly closed original container in a dry, cool and well ventilated place. Handling: Avoid breathing vapors and mists. Avoid direct or prolonged contact with skin and eyes.

Storage

Store in tightly closed containers. Store in an area that is clean, well-ventilated, away from ignition sources, away from incompatible materials (see Section 10. Stability and Reactivity). 8. EXPOSURE CONTROLS/ PERSONAL PROTECTION Introductory Remarks: These recommendations provide general guidance for handling this product. Because specific work environments and material handling practices vary, safety procedures should be developed for each intended application. While developing safe handling procedures, do not overlook the need to clean equipment and piping systems for maintenance and repairs. Waste resulting from these procedures should be handled in accordance with Section 13: Disposal Considerations. Assistance with selection, use and maintenance of worker protection equipment is generally available from equipment manufacturers. This product can form formaldehyde vapors when heated to temperatures above 150 degrees C in the presence of air. Formaldehyde is a potential cancer hazard, a known skin and respiratory sensitizer, and an irritant to the eyes, nose, throat, skin, and digestive system. Safe handling conditions may be maintained by keeping vapor concentrations within the OSHA Permissible Exposure Limit for formaldehyde. Exposure Guidelines: No exposure limits were found for this product or any of its ingredients. Engineering Controls: Where engineering controls are indicated by use conditions or a potential for excessive exposure exists, the following traditional exposure control techniques may be used to effectively minimize employee exposures: general area dilution/exhaust ventilation. Respiratory Protection: When respirators are required, select NIOSH/MSHA approved equipment based on actual or potential airborne concentrations and in accordance with the appropriate regulatory standards and/or industrial recommendations. For reasonably foreseeable industrial end uses of this material, respiratory protection should not be necessary. Eye/Face Protection: Wear approved safety glasses. Skin Protection: Skin contact should be minimized through use of gloves and suitable long-sleeved clothing (i.e., shirts and pants). Work Practice Controls: Personal hygiene is an important work practice exposure control measure and the following general measures should be taken when working with or handling this material: (1) Do not store, use, and/or consume foods, beverages, tobacco products, or cosmetics in areas where this material is stored. (2) Wash hands and face carefully before eating, drinking, using tobacco, applying cosmetics, or using the toilet. (3) Wash exposed skin promptly to remove accidental splashes or contact with this material. 9. PHYSICAL AND CHEMICAL PROPERTIES Physical Appearance: Translucent solid Odor: odorless. pH: Not Applicable Specific Gravity: 1.12 at 25 C (77 F). Water Solubility: Insoluble Melting Point Range: Not Available Freezing Point Range: < 0 C (32 F) Boiling Point Range: > 260 C (500 F) at 760 mmHg Vapor Pressure: No data available Vapor Density: No data available Autoignition Temperature: > 572 F ( 300 C) 10. STABILITY AND REACTIVITY Stability: This material is stable under normal handling and storage conditions. Possibility of Hazardous Reactions: Will not occur Conditions to avoid: None known Decomposition Type: thermal dimethylcyclosiloxanes methylphenylcyclosiloxanes Incompatible Materials: Stong, oxidizers, strong acids, and strong bases Hazardous Decomposition Products: Thermal decompostion may liberate dimethylscyclosiloxanes and methylphenylcyclosiloxanes. This product can form formaldehyde vapors when heated to temperatures above 150 degrees C in the presence of air.
