A crew of 6 to 8 employees were relining a sewer pipe using a concrete liner system. The employees are required to pump hot water through the liner to cure the concrete. As the employees were disconnecting the hose from the system, residual pressure from an unknown source caused two employees to be sprayed with hot water (greater than 190 degrees Fahrenheit). Employee 1 sustained second-degree burns to his torso and employee 2 sustained second-degree burns to both feet. Both employees were hospitalized.
