Nail gun study finds training and 'sequential' tool cut injuries - By Andrew McIntosh, Sacramento Bee
Apprentice carpenters who use a sequentially fired nail gun and get proper training before operating the tool suffer far fewer injuries, says a study published today in the American Journal of Industrial Medicine.
The findings, based on a three-year study of 1,962 apprentices in St. Louis, may push California workplace safety officials to consider whether rookie carpenters here could be forced to use the safer tool.
California earlier this year adopted rules requiring nail gun training for all operators.
Duke University professors Hester Lipscomb and John Dement, with carpenters James Nolan and Dennis Patterson from the Carpenters District Council of Greater St. Louis, did the research.
'Our data shows that the law should require both the safer sequential firing system and training,' Lipscomb said Wednesday.
The group interviewed the 1,962 apprentices between 2005 and 2007; 384 were hurt by nail guns.
Most nail guns offer an automatic or "contact-trip" firing system. They fire when both the trigger is pulled and the tool's nose or workpiece is pressed against wood or another object – in any order.
