Pneumatic Nail Guns: Revisiting Trigger Recommendations

IN BRIEF •Use of a pneumatic nail gun with a sequential actuation trigger (SAT) significantly diminishes the risk for acute traumatic injury compared to use of a nail gun equipped with a contact actuation trigger (CAT). •A theoretically based increased risk of work-related musculoskeletal disorders from use of an SAT nail gun, relative to CAT, appears unlikely and remains unproven. •Based on current knowledge, use of CAT nail guns cannot be justified as a safe alternative to SAT nail guns. The authors, who are ergonomists and occupational safety researchers, recommend the use of the SAT for all nail gun tasks in the construction industry.
