Flow Path Identification & Stream Placement
With the recent release of the UL Stream study, we thought it would be relevant to share a short education video on flow path identification and stream placement. In this video,(filmed in Ottawa Canada with a Bullard LDX TIC) one can easily identify convection heat currents and a bi-directional flow path at the door. The crew leader continually guides the stream, cools, confirms, and communicates where to move to next. Several valuable lessons are in this short video: Flow paths must be identified and controlled, Do not advance in an exhaust, do not stand up in these convective heat currents, control the air behind you, the area must be continually cooled and often too much water is applied to the ceiling instead of coating the walls and floor which allows moisture to move into the molecular air movement path which is often carried to the base of the fire.
