In the event of a power outage, which critical equipment should you check for functionality?

• A. Coffee machines and vending machines.
• B. Emergency lighting, PA system, elevators/escalators, and communication devices.
• C. Security cameras only.
• D. Public address announcements only.

Answer: (B)

During a power outage, the main priority is safety and clear communication. In that scenario, you want systems that keep areas visible, allow urgent instructions to passengers, and support safe movement and coordination. The best choice includes emergency lighting to illuminate exits and routes, the public-address system to broadcast safety guidance, elevators and escalators to help people move between levels (especially for those with mobility needs), and reliable communication devices so staff can coordinate with each other and with responders. Together, these elements enable people to evacuate safely and allow responders to manage the situation.

Coffee machines and vending machines have no safety function during an outage. Relying on public-address alone misses crucial visibility and mobility needs, and focusing only on security cameras doesn’t guarantee you can guide or move people or exchange information effectively.
