DOT Classification: 8; Label: Corrosive
Specification
Such as: When on the skin: first,should flush skin with plenty of water immediatelyfor at least 15 minutes while removing contaminated clothing. Secondly,Get shoesmedical aid . Or in the eyes: Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids.Then get medical aid soon.While ,it's Inhaled: Remove from exposure and move to fresh air immediately.Give artificial respiration while not breathing. When breathing is difficult, give oxygen. And as soon as to get medical aid. Then you have the ingesting of the product : Do not induce vomiting.Wash mouth out with water,and get medical aid immediately.
In addition, Antimony trifluoride (CAS NO.7783-56-4) can be stable under normal temperature and pressure conditions.It is not compatible with metals, strong acids, and you must not take it with incompatible materials and not be exposured to moist air or water.And also prevent it to broken down into hazardous decomposition products: hydrogen fluoride gas, antimony/antimony oxides.
