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