In the event of electrical fibrillation, who should operate the defibrillator?

• A. Trained supervisor
• B. Qualified person
• C. On-site nurse
• D. Electrician

Answer: (B)

Operating a defibrillator requires someone who is trained and authorized to perform life-saving actions. A qualified person is the one who has received formal training in CPR and AED use and is empowered by the organization to carry out emergency interventions. This ensures they can correctly place pads, follow the device prompts, deliver shocks only when indicated, and coordinate with EMS for aftercare. In many workplaces, this designation is used to identify who can perform this procedure safely and effectively, including awareness of electrical hazards and scene safety. A trained supervisor or on-site nurse could also be qualified, but the important point is having that recognized, authorized competence to use the device. An electrician, while skilled in electrical work, may not have the necessary defibrillator training, so relying on someone without that qualification could delay or mishandle treatment.
