Do not use lift in the event of a fire

At almost every elevator the warning is appropriate and actually everyone knows that the elevator should not be used in case of fire. However, this is gradually changing, as people with disabilities or wheelchair users eventually need it. Many elevators are now being built so that
they should even be preferred in case of fire.

Why should the elevator not be used in case of fire?

Everyone knows the sentence, but many do not realize why the elevator should not be used. On the one hand, an elevator requires electricity, on the other hand, the elevator could just keep in the floor in which the actual fire is located.

Power failure with fire

Without electricity, the elevator does not work. Hardly anyone can predict when the electricity will be lost in a fire. Under certain circumstances, it is also switched off by the fire department.

Above all, if there is a photovoltaic system on the roof, the fire department has a main switch that switches the entire building off-line, so that the firefighters do not suffer a blow when deleting. If the power fails, if you have not reached the bottom yet, you will inevitably be trapped.

Chimney effect in the elevator

Since the lift leads from the bottom up like a chimney, the smoke will use this path. The toxic gases spread throughout the elevator shaft and suffocate any passenger who is still in it.

Photocell fails

If the elevator door opens on a floor filled with smoke, it can not close. As the doors are checked for safety reasons with a light barrier, if someone is still between the closing doors, the smoke is interpreted incorrectly by the light barrier and the doors remain open. That is, the elevator stops in this smoky floor. The passenger would now have to find the escape staircase in this smoky, unfamiliar floor to escape.

Reasons against using an elevator:

  • Power failure
  • chimney effect
  • Photocell at the door

What's different about the new elevators?

These elevators are specially controlled to keep them away from a smoky or burning floor. In the elevator shaft, a negative pressure is generated, which prevents the smoke from spreading. In addition, all electrical elements and controls are protected so that extinguishing water can not reach them. In addition, in an elevator with a "service extension in case of fire", the controls are lowered so that even children can reach them.

How do I know if the elevator is allowed to be used in case of fire?

Such elevators are marked either as an evacuation elevator or as an elevator with a service extension in case of fire. Once the fire department arrives, however, it has all the privileges to use this elevator.

Tips & Tricks

Always use the elevator waiting time to see the escape plans. Especially if it is a confusing building that you do not know yet. Who makes this a habit, has in case of emergency, a big advantage.
