This case involves an injury to a construction worker. The plaintiff, a twenty-eight-year-old male, was constructing a deck using a compressed air nail gun. The nail gun had a safety mechanism that did not allow the gun to fire a nail unless the muzzle was pressed against a surface. However, while the plaintiff was using the gun, the muzzle became stuck, and the gun fired three nails into the plaintiff’s leg. The plaintiff sustained extensive injuries and was forced to miss two months of work.
