Which practice helps reduce ignition risk when using electrosurgical units (ESUs)?

Answer
The correct practice to reduce ignition risk when using electrosurgical units is holstering the electrode when not in use. Leaving the active tip on the patient, activating the pencil anytime, or using improper covers can lead to accidental activation or tissue burns, whereas properly holstering the active electrode isolates it and prevents unintended thermal injuries or fires.
