Here’s a guide on what to do if you find yourself stuck in an elevator during a power outage:

1. **Stay Calm and Avoid Panic:**
The most important thing is to remain calm. Take deep breaths to stay composed and avoid making the situation more stressful.

2. **Press the Alarm Button:**
Use the emergency alarm button inside the elevator. This will alert building management or emergency services to your situation and prompt a response.

3. **Avoid Trying to Open the Elevator Door:**
It’s unsafe to try and force open the elevator doors yourself. Wait for trained professionals who can safely handle the situation without risk of injury.

4. **Call the Emergency Number (112):**
If the alarm button doesn’t work or if you have a mobile phone, call the emergency number 112. Provide your location and details about being stuck in the elevator.

5. **Sit Down to Relieve Stress:**
Sitting down can help reduce stress and conserve energy while you wait for help. It’s a safer position in case the elevator moves unexpectedly.

By following these steps, you can stay safe and manage the situation effectively until professional assistance arrives. Remember, staying calm is key to ensuring a safe resolution.
