What must any individual utilizing an electric file demonstrate?

To utilize an electric file safely and effectively, an individual must demonstrate proficiency in the use of the instrument. This proficiency includes understanding how to operate the electric file correctly, handle different speeds, and apply the appropriate pressure to achieve the desired results while minimizing risks such as injuries or damage to the natural nails. Mastery of the electric file is essential because improper use can lead to burns or discomfort for the client, as well as preventable accidents.

While familiarity with other manicuring tools, basic knowledge of salon operations, and experience with nail art can be beneficial, they do not specifically address the critical requirement of being skilled in the use of an electric file, which is key to providing quality service and maintaining client safety.
