Consider this scenario from a secondary school. A teacher is running a food technology lesson. Before the class, she brings extra supplies from another room in several cardboard boxes. After unpacking them, she flattens the boxes and leaves them outside the classroom door for the cleaners to collect later. During the lesson, a pupil spills some flour. The teacher tells the pupil to stop work and clean it up immediately.
She also reminds the class to put their rubbish in the bins placed next to each hob, for convenience. At the end of the lesson, she asks the pupils to make sure their electric hobs are fully switched off, and to tidy their stations. The pupils clean up and leave mixing bowls, utensils, flour and cooking oils neatly on the counters, close to the hobs.
The teacher glances briefly around the room, switches off the lights and locks the door as she leaves. Before moving on, think about which of these actions helped fire safety, and which created a risk.
