Here are my favourite health and safety props to help discussions about power tools as work equipment. They are lightweight and each have action features and noise without need for batteries. They are precious now as I have not found them anywhere since. It makes such a difference to handle and play with these while talking through competence, maintenance, fault reporting, electrical safety, PPE etc. Who needs PowerPoint???!!!
"The Creative Trainer" - by David Newsum 
P.S. you can find these elsewhere just google toy drill s etc. but they are quite expensive, whereas I paid just a £1 each!!!!
Seem familiar – still have some – used them for both first aid and health and safety training when teaching, For the former in scenarios added some red paint. The most effective was the drill that looked really great with red paint and the added mock blood.
Thanks Peter – yes I have a severed hand!!!! Best regards
