What must be done to electrical equipment before using it on a client?

To ensure client safety and maintain a professional standard, electrical equipment must be thoroughly inspected for any signs of damage before use. This includes checking for frayed cords, exposed wires, and any other defects that could pose a risk of injury or malfunction. Proper maintenance is also crucial, as it ensures that the equipment operates efficiently and safely. Regular inspections and maintenance help to prevent accidents and ensure compliance with health and safety regulations.

While cleaning with alcohol is a good practice for hygiene, it does not guarantee the safety of the equipment in terms of functionality and potential hazards. Charging the equipment fully may be important in some situations, but it does not address the safety concerns associated with damaged equipment. Covering the equipment with a protective sheet does not relate to its safety or operational state. Thus, the focus on inspecting and maintaining electrical equipment is vital for both the technician's and the client's safety during any nail service.
