| [Fire Fighting] Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Extinguishing media: Substance is noncombustible; use agent most appropriate to extinguish surrounding fire. Use agent most appropriate to extinguish fire. | |
| [Ingestion] If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Get medical aid immediately. | |
| [Inhalation] Get medical aid immediately. Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. | |
| [Skin] Get medical aid. Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse. | |
| [Eyes] Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately. | |
| [Storage] Store in a cool, dry place. Keep container closed when not in use. | |
| [Handling] Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use with adequate ventilation. Avoid contact with eyes, skin, and clothing. Avoid ingestion and inhalation. | |
| [Inhalation] May cause respiratory tract irritation. May cause lung damage. Contains crystalline silica which may lead to respiratory abnormalities and silicosis. | |
| [Skin] May cause skin irritation. | |
| [Eyes] May cause eye irritation. | |
| [Ingestion] May cause gastrointestinal irritation with nausea, vomiting and diarrhea. | |
| [Personal Protection] Eyes: Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166. Skin: Wear appropriate gloves to prevent skin exposure. Clothing: Wear appropriate protective clothing to minimize contact with skin. | |
| [Respirators] A respiratory protection program that meets OSHA's 29 CFR 1910.134 and ANSI Z88.2 requirements or European Standard EN 149 must be followed whenever workplace conditions warrant a respirator's use. Wear a NIOSH/MSHA or European Standard EN 149 approved full-facepiece airline respirator in the positive pressure mode with emergency escape provisions. | |
| [Exposure Effects] Chronic inhalation of dust may lead to silicosis. | |
| [Poison Class] F (Not subject to toxicity classification) | |
| [Appearance] Colorless, odorless solid. | |
| [Solubility in water] Insoluble | |
| [Melting Point] 1710 | |
| [Boiling Point] 2230 | |
| [Density] 2.196 g/cm3 (20 C) | |
| [Usage] Vitreous or fused silica is used as laboratory glassware in chemical laboratories and in the semiconductor industry; thin-film dielectric coating in integrated circuits; electric-resistance furnaces and radiant heaters, and protection of precious-metal themocouples; as a refractive optical material, used for prisms, camera lenses, cells, solar cell covers, spacecraft windows, and other optical components; in mirror blanks of astronomical telescopes; as a component of laser optics; as an envelope material for mercury-vapour and incandescent tungsten-halogen cycle lamps; as a chromatography substitute, inert filler or as a coating material in the investment-cast industry; insulation or packing material. | |
