Symptoms of fire Last week during ICT, we were treated to the usual round of lectures, done by instructors in an army of the 21st century - powerpoint slides, flash animations, the works. Lectures usually precede practical field training, and despite our sniggering, they usually help in our understanding of what we're supposed to do in the field. Except for our fire evacuation drill. The first slide was of five points, and titled 'the five symptoms of fire'. My mates and I spent the next twenty minutes giggling, and could only remember three 'symptoms': heat, bright light and smoke. 'Symptoms of fire' became our catchphrase for the week.
