I could not determine how these are packaged, is it possible to quickly remove and isolate the burning unit, or is the fire going to spread to adjoining units?

Here's an idea. Tesla and SpaceX cooperate with their technologies.

Add a rocket pack underneath each unit. If the system detects a burning unit, ignite the rocket pack and steer the burning unit far out into the Pacific Ocean.

From what I have read the answer is to throw the burning unit into a hole and cover it with dirt until it burns itself out in a few days.
