Of obvious concerns is the fact that EDM uses very high voltage electricity. The operator needs to make every effort to be constantly aware of the machine and its surroundings. Coming into contact with any part of the fluid or the electrode can cause severe injury or even death.

A second concern is the dielectric fluid, which is an oil based liquid. As with any oil, the proper handling of parts, measuring tools, etc. should be taken into consideration
