Whiteboard Drawing 2: roof ventilation

Whiteboard drawing detailing roof operations
The drawing above briefly summarizes the roof operations my crew has been training on over the last couple shifts.

By using two roof ladders, firefighters are able to safely cut a vent hole without needing to step off the ladder.

In the drawing, the first firefighter (top left) has finished their cuts and has started to open the roof. The second firefighter (bottom center) has just finished the bottom cut, and is handing the saw off to the lieutenant, then the two firefighters will work together to open the hole with hand tools.

Another important note is to never lean/pull or put your weight on a chimney, for obvious reasons.
