Per an article in "This Old House" magazine there are 14,800 nail-gun accidents a year among nonprofessions which I think would include many of us. Norm's friend Tom Silva offers these safety tips: - Take your finger off the trigger immediately after you're driven in a fastener - Use a nailer with a sequential-trip trigger - Wear safety glasses - Never aim the business end at a hand or any body part - Keep digits at least 10 inches to the side of the impact point - Remove the gun from the power source when loading or clearing jams We probably all have seen fired nails glance off hidden knots and nails causing fish-hooking. This article was a wake-up call for me.
