Manditory Evacuations?

Question

There is a big fire that started about 8am not to far from here. I can see the big plumes of smoke. It's not to far from Disneyland.

On the news they are saying 200 homes have been made manditory evacuated. Many homeowners want to stay and help but the Fire fighters have the right to evacuate.
