Does a Pneumatic Nail Gun fall under the classification of an explosive power tool. With reference to or in terms of Constr regs 2014. CR 21. Seeing there is no definition of this in the regs.This is similar to a pellet gun and fires nails just as a Hilti gun with a cartridge. The end result is the same it is just that one is operated by an explosive cartridge and the other by a high powered burst of compressed air.Which ejects the projectile with the same force as a cartridge.
