7、t 15 minutes while removing contaminated clothing and shoes. Discard contaminated clothing in a manner which limits further exposure.Ingestion: Do NOT induce vomiting. If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Get medi
8、cal aid immediately.Inhalation: Remove from exposure to fresh air immediately. If breathing is difficult, give oxygen. Get medical aid. Do NOT use mouth-to-mouth resuscitation. If breathing has ceased apply artificial respiration using oxygen and a suitable mechanical device such as a bag and a mask
9、.Notes to Physician: Treat symptomatically and supportively.5) Fire Fighting MeasuresGeneral Information: As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Contact with metals may evolve flammable hydrogen gas
10、. Containers may explode when heated.Extinguishing Media: Do NOT get water inside containers. For small fires, use dry chemical, carbon dioxide, or water spray. For large fires, use dry chemical, carbon dioxide, alcohol-resistant foam, or water spray. Cool containers with flooding quantities of wate
11、r until well after fire is out.6) Accidental Release MeasuresGeneral Information: Use proper personal protective equipment as indicated in Section 8. Spills/Leaks: Remove all sources of ignition. Absorb spill using an absorbent, non-combustible material such as earth, sand, or vermiculite. Do not us
12、e combustible materials such as saw dust. Provide ventilation.7) Handling and StorageHandling: Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use with adequate ventilation. Do not get in eyes, on skin, or on clothing. Do not ingest or inhale. Discard contaminated
13、 shoes.Storage: Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances.8) Exposure Controls, Personal ProtectionEngineering Controls: Use process enclosure, local exhaust ventilation, or other engineering controls to control airborne levels
