Using entertaining yet informative experiments, Capt. Doug Watson demonstrates how various physical laws of science apply to the fireground operations. In this DVD, Capt. Watson illustrates heat and its effects on smoke and pressure; he measures and quantifies the effect of hand placement when forcing a door; and he assesses the effect of footing a ladder from the front versus from the back. A solid understanding of fireground dynamics gives the firefighter tools to be safe and more efficient.
