What safety measure should be observed while using galvanic currents?

When using galvanic currents, ensuring proper grounding is crucial for safety. This measure helps prevent electrical shocks that can arise from faults in the equipment or improper handling. Proper grounding directs any excess electrical current safely away from the body, minimizing the risk of electrical accidents during the procedure. This is particularly important in environments where moisture is present, as it can increase the risk of conductivity and electrical hazards.

While wearing gloves can provide a barrier and protect the skin from potential irritation, and protective eyewear is important for shielding the eyes from any incidental splashes or light, they do not address the fundamental risks associated with the electrical aspect of galvanic currents. Limiting treatment time can help mitigate the risk of overheating or discomfort, but it does not directly contribute to electrical safety. Therefore, proper grounding stands out as the most critical safety measure when working with galvanic currents.
