The MSDS serves to communicate information about the properties of the chemical to the user as well as information necessary for emergency response personnel in the event of a contingency. In addition, MSDS also contain sections on health effects and spill clean-up. MSDSs for chemicals present in a laboratory must be maintained on file in the laboratory, and should be reviewed periodically, especially when using unfamiliar chemicals. For an explanation of some common MSDS terms, see Appendix XV, MSDS Acronyms and Definitions. The lower molecular weight ethers can be dangerous fire and explosion hazards.
Some ethers form explosive peroxides on exposure to air and light.
Therefore, old ether containers that have previously been opened pose a serious problem in terms of handling and disposal. Order only the amount of ether required. Do not open multiple containers simultaneously. Attempt to utilize the ether as soon as possible. Once the container is empty, rinse with alcohol or other fat solvent.
