Hygroscopic (absorbs moisture from the air).The toxicological properties of this material have not been fully investigated. Potential Health Effects Eye: No information regarding eye irritation and other potential effects was found. Skin: No information regarding skin irritation and other potential effects was found. Ingestion: The toxicological properties of this substance have not been fully investigated. Inhalation: Inhalation of dust may cause respiratory tract irritation. Chronic: No information found. Section 4 - FIRST AID MEASURES Eyes: Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately. Skin: Get medical aid. Flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. 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: Remove from exposure and move to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid. Notes to Physician: Section 5 - FIRE FIGHTING MEASURES General Information: As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Extinguishing Media: Use agent most appropriate to extinguish fire. Section 6 - ACCIDENTAL RELEASE MEASURES General Information: Use proper personal protective equipment as indicated in Section 8. Spills/Leaks: Sweep up or absorb material, then place into a suitable clean, dry, closed container for disposal. Avoid generating dusty conditions. Section 7 - HANDLING and STORAGE Handling: Wash thoroughly after handling. Use with adequate ventilation. Minimize dust generation and accumulation. Avoid contact with eyes, skin, and clothing. Keep container tightly closed. Avoid ingestion and inhalation. Storage: Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances. Section 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION Engineering Controls: Use adequate ventilation to keep airborne concentrations low. Exposure Limits CAS# 17272-46-7: Personal Protective Equipment 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 protective gloves to prevent skin exposure. Clothing: Wear appropriate protective clothing to prevent skin exposure. Respirators: Follow the OSHA respirator regulations found in 29 CFR 1910.134 or European Standard EN 149. Use a NIOSH/MSHA or European Standard EN 149 approved respirator if exposure limits are exceeded or if irritation or other symptoms are experienced.
