Explosive powder actuated tool

Today we spent the majority of the day learning about the correct and safe use of explosive powder actuated tools. It was a pretty interesting unit and we learnt about choosing the correct fasteners for the job, depending on what material we are fixing to what, steel, wood and concrete. The main focus of this unit was safety as the gun is very much like a real gun. we learnt about the difference between direct and indirect firing (piston or no piston). After we had a few shots each we filled out the work book which reinforced what we'de learnt about the safety issues and types of nails and strength of charges.
