Abstract: At approximately 11:00 a.m. on November 6, 2012, Employee #1, a 46-year-old male journeyman carpenter-framer with Ellison Framing Inc., was assigned to work with a crew to do framing work on the second floor of building number three of the ongoing multi-family construction. Employee #1 was framing a wall on the floor of the building using a nail gun and 2 in. by 4 in. wood when he struck his right foot while trying to nail a 2 in. by 4 in. studding. Employee #1 discharged a 16-guage nail, (less than three-inches) into his foot with the nail gun. Afterwards, Employee #1 pulled the nail from his foot with the use of a hammer and continued working. However, because the pain persisted, Employee #1 went to the company's trailer office and told the Project Engineer what happened. Employee #1 sought medical treatment and was hospitalized as a result of unspecified injuries to his right foot that was punctured by a nail fired from a nail gun. Ellison Framing, Inc. was a licensed General Building Contractor specializing on wood framing works. They operate in the Bay Area and employs more than a hundred employees. Employee #1 had worked for Ellison Framing Inc. for twelve years and was a permanent full-time employee and a journeyman framer for the company.
