At 8:30 a.m. on June 22, 2020, Employees #1 and #2, employed by a piping company, were working at a multi-employer construction project, a three-story food processing company.  They were adding new pipe to two new, already installed, 14-inch diameter chilled water lines.  The chilled water lines had been pressure-tested with nitrogen.  As Employee #1 attempted to remove the cap from the end of a chilled water line, nitrogen pressurized to 115 psi was released and struck both employees.  Employees #1 and #2 sustained blunt force
