When there is an unwanted or threatening person attempting to enter the facility you should?

Follow these steps:

1. Immediately call the police.

2. While waiting for the police, try to keep the person outside the facility. You can do this by:

* Locking the doors and windows.

* Putting up a barricade.

* Using a fire extinguisher or other object to deter the person.

3. If the person does manage to get inside, try to stay calm and avoid any physical confrontation. You can:

* Move away from the person and try to find a safe place to hide.

* Call the police again and tell them that the person is now inside.

4. Do not attempt to apprehend the person yourself. This is a job for the police.
