We have to evacuate the clinic.

Now, Will, we better be getting cleared away...

We must be prepared to abandon ship.

That is very dramatic, but our role is to take the drama out of things and foster dialogue.

We stopped the ambulance with the engine on, in the middle of a crossing, communicating our whereabouts via phone to the relatives of some patients on their way.

While I'm digging the grave, you get your things together, all the things you want to carry, and then we can clear out of here in a hurry.
