Abstract: At 11:00 a.m. on October 7, 2020, a local fire department employee was participating in a standpipe drill at the department local training center. The employee was on the 3rd floor turning on a water valve near the fire escape. The standpipe outlet was approximately a foot away beyond the fire escape railing. The Y-outlet itself had two outlets to accommodate the attachment of 2 hoses. It is a policy that the outer outlet that is furthest away from the fire escape be connected and it was so connected. Partway through the drill, for reasons unknown, the employee went from the floor onto the fire escape and turned on the lever for the 2nd outlet of the Y-valve (which had no hose attached). This caused water to flow out the valve at 100 psi, hitting the employee and pushing him off balance and backwards over the railing. He fell approximately 27 feet to the ground, suffering blunt force head trauma and was killed.
