SECTION 2: Hazards identification

OSHA Classification Physical Health Not Hazardous

2.1 Classification of the substance or mixture

Physical Health Not Hazardous Label Elements Not hazardous in accordance with the GHS and OSHA Hazcom 2012. 3. COMPOSITION / INFORMATION ON INGREDIENTS Chemical name CAS No. Percent Synthetic Amorphous Silica 7631-86-9 40-50% Methylsilylated Silica 68909-20-6 10-20% Polyethylene Terephthalate (PET or polyester) 25038-59-9 10-20% Fibrous Glass (textile grade) Not Applicable 10-20% Magnesium Oxide 1309-48-4 0-5% Synthetic Graphite 7782-42-5 0-5% The exact percentage (concentration) of composition has been withheld as a trade secret. 4. FIRST-AID MEASURES Inhalation: If dust is inhaled, remove to fresh air. Drink water to clear throat, and blow nose. If irritation occurs or symptoms develop, seek medical attention. Spaceloft® Skin contact: Wash skin with soap and water. If irritation develops, seek medical attention, launder clothing before reuse. Eye contact: Do not rub eyes. Dust particles may cause abrasive injury. Immediately flush eyes with water while lifting the upper and lower lids. Seek medical attention if irritation persists. Ingestion: No first aid is generally required. No adverse effects are expected from incidental ingestion. Most important symptoms/effects, acute and delayed: Dust may cause eye irritation. Silica aerogels are hydrophobic (repel water) and may cause temporary drying and irritation of the skin, eyes, and mucous membranes. Inhalation of dust from handling may cause temporary upper respiratory tract irritation. Handling may cause dryness and irritation of the skin. Indication of immediate medical attention and special treatment, if necessary: Immediate medical attention is generally not required. 5. FIRE-FIGHTING MEASURES Extinguishing media: Use any media that is suitable for the surrounding fire. Specific hazards arising from the substance or mixture: Product is a super-insulator. Rolls of material will retain heat within internal layers that may be a source of ignition after the fire is extinguished. Keep hot material away from combustible materials and cool hot insulation with water. Special protective equipment and precautions for fire-fighters: Normal firefighting procedures should be followed to avoid inhalation of smoke and gases produced by a fire. 6. ACCIDENTAL RELEASE MEASURES Personal precautions, protective equipment, and emergency procedures: Wear appropriate protective clothing and equipment as described in Section 8. Avoid generating airborne dust during cleanup. Ensure adequate ventilation. Environmental Precautions: Material is not water soluble. Report spills as required under federal, state and local regulations. Methods and materials for containment and cleaning up: Collect using methods that avoid the generation of dust (pick up or vacuum dust) and place in appropriate container for disposal. 7. HANDLING AND STORAGE Precautions for safe handling: Aerogel blankets may generate dust when handled. Workplace exposures to all dusts should be controlled with standard industrial hygiene practices. Local exhaust should be the primary dust control method. Dust generated when handling this product should be cleaned up promptly. Dry vacuuming is the preferred method for cleaning up dust. Because aerogel dust is hydrophobic, water is not an effective dust control agent. Unpack material in the work area. This will help to minimize the area where dust exposure may occur. Trimmed material should be promptly packed in disposal bags. Trims and offcuts may be reused in secondary applications, otherwise scrap material should be packed for disposal. Avoid dust contact with eyes, skin and clothing and avoid breathing dust. Wash hands with soap and water after handling. Spaceloft® Conditions for safe storage, including any incompatibilities: Keep tightly closed in the packaging until ready for use. Store in a dry location. 8. EXPOSURE CONTROLS / PERSONAL PROTECTION Exposure guidelines: Synthetic Amorphous Silica 6 mg/m3 TWA OSHA PEL* Methylsilylated Silica (as particulates not otherwise 5 mg/m3 (respirable), 15 mg/m3 (total dust) TWA classified) OSHA PEL Polyethylene Terephthalate (PET or polyester) (as 5 mg/m3 (respirable), 15 mg/m3 (total dust) TWA particulates not otherwise classified) OSHA PEL Fibrous Glass (textile grade) 5 mg/m3 (respirable), 15 mg/m3 (total dust) TWA OSHA PEL 5 mg/m3 (inhalable) / 1 fiber/cc TWA ACGIH TLV Magnesium Oxide 15 mg/m3 (total dust) TWA OSHA PEL 10 mg/m3 (inhalable) TWA ACGIH TLV Synthetic Graphite 5 mg/m3 (respirable), 15 mg/m3 (total dust) TWA OSHA PEL 2 mg/m3 (respirable) TWA ACGIH TLV *Equivalent to 20 mppcf; 54 FR 2701 Appropriate engineering controls: Use with adequate local exhaust ventilation to minimize exposures. Provide local exhaust ventilation where product is processed in a manner that generates dust. Individual protection measures: Respiratory protection: If exposures exceed the occupational exposure limits or if inhalation of dust results in experiencing irritation, an appropriate certified particulate respirator is recommended. Selection of respiratory protection depends on the contaminant type, form and concentration. Select and use in accordance with OSHA 1910.134 and good Industrial Hygiene practice, e.g. a NIOSH approved P100 or N100 particulate filtering facepiece respirator Skin protection: Impervious gloves recommended for handling product. Long-sleeved and long-legged work clothing are also advised. Eye protection: Safety glasses with side shields or dust goggles recommended. Other: None known. 9.
