Posted By willhiem should you not get someone who is trained in its use to go with you and you both do it? colour blindness is an issue also for users/ oh and never use it at an angle!!! unless you like seeing nails lodged in unusual body parts!!

Posted By Anthony Edwards Thanks for the responses so far. I am aware of some possible risks such as: Ensuring the gun is positioned correctly prior to firing. Correct PPE. Training. Working area being free from trip hazards. I am more interested if there is an issue regarding 'kick back' when firing. loading of nails etc. Regards Nutty

Posted By lewes I would have also thought that the operative needs to ensure there are no persons working the other side of the penetration area (behind where you are nailing) This HSS leaflet (other tool hire company's are available) could give you a basic idea of how the equipment works http://www.hss.com/imagshop/guides/og_550.pdf

Posted By D H Willhiem - I was called in by a client to investigate an incident recently where an operator nailed his thumb to a bench. Yes it was reported that the nail (6 inch)had deflected from a knot - but the injury was also assisted by the fact that the operator had not put the wood flat on the bench, jammed it into its "locking area" as with the work place procedure. The trigger was also being held from full release of pressure after nailing "to save time". Other operators claimed nails are often deflected by knots, but after the incident, I did not witness any deviation from the procedures and no deflection of nails. I strongly suspect that if the work piece is properly secured then deflection chances may be low? Dave
