Specification
(R)-(-)-1-METHOXY-2-PROPANOL(4984-22-9) is hazardous,so the first aid measures and others should be known .Such as:
Skin: Get medical aid. Should flush skin with plenty of water immediatelyfor at least 15 minutes while removing contaminated clothing and shoes.
Eyes: Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids.Then get medical aid soon.
Inhalation: Remove from exposure and move to fresh air immediately. when breathing is difficult, give oxygen.And as soon as to get medical aid.
Ingestion: Wash mouth out with water,and get medical aid immediately.
Notes to Physician: Treat supportively and symptomatically.
Polymerization of the (R)-(-)-1-METHOXY-2-PROPANOL(4984-22-9) can be stable under normal temperature and pressure conditions.It is not compatible with strong oxidizing agents, and you must not take it with ignition sources and incompatible materials.And also prevent it to broken down into hazardous decomposition products: carbon dioxide,carbon monoxide.
