We were shocked about the emerging understanding about the dangers of smoke, particularly from plastics. We learned about compartment fires, flashover and backdraft, and the different methods of fire attack. We also estimated fire loads in terms of pounds per square foot of wood or synthetic materials using British thermal units (Btus) per pound. We conversed in a language that had very few numerical terms: temperature [Fahrenheit (°F)], water volume (gpm), and water pressure (psi). It was that simple. In recent years, significant advances have included computer…
