At 10:15 a.m. on February 12, 2015, an employee was working from the elevated basket of a manlift, installing sheetrock in an area of the job site where water piping was undergoing pneumatic testing, at 130 psi. At the same time, another contractor was performing a compressed air leak test. An 80-pound section of the pipe under pressure dislodged and struck and killed the employee in the elevated basket of a manlift.
