 cells before any pain can be felt. In the event of contact with methoxide, rinse the contacted area with water, seek medical attention immediately.

Making sodium methoxide is dangerous, involving H2 and lots of heat. In addition, the resultant chemical is highly toxic. For this reason, the safety of the design of equipment and workspace should be carefully considered before use, and protective clothing and a respirator should be worn during handling. Only as much as is intended to be used immediately should be created.
