I would like to announce to the world that I have made an enormous breakthrough in the area of fire extinguisher training. This new method of mine is pollution neutral, 100% safe and clean for the users and is very easily transported. "How on earth did you do that NT you clever thing?" I hear you all ask.
Well, with the trainee in the middle of a room, I stand in any corner with a red rag and when he is least expecting it I shout out "Yoohoo, I'm a fire and I'm over here" and frantically wave the flag. The trainee points an imaginary fire extinguisher at me and goes "Schhhhhhhhhht" until I stop shouting and waving the flag. Because it is so portable and adaptable I can then go to another room and do the same thing again. It can even be used to train many at the one time.
The system can be enhanced by hiding behind a box or cupboard and then taking the trainee completely by surprise, even from behind.
What ya think people?
NB. This process is patent pending and any attempt to copy all or any of it will mean that the potential thief is a cuckoo and needs help.
