Tactical Integration

Each of the UL ventilation studies has generated a list of tactical considerations, many of which overlap or reinforce one another. It is useful to revisit the tactical considerations developed in the horizontal ventilation study and to integrate these with those resulting from the vertical ventilation research project. Download the Tactical Integration Poster as an … Read more

Theory and Practice

Recently I have been following a series of discussions on Facebook on the relative merits of compressed air foam (CAF) versus water as an extinguishing agent. Some of my colleagues profess that CAF is superior in all respects and in all applications for extinguishment by cooling. Others point to the limited ability to cool hot … Read more
