Report: Water blast knocked California firefighter over rail

SAN FRANCISCO — A San Francisco firefighter who died this week was knocked over a third-floor railing by a water blast from a valve he had “inadvertently” opened during a training exercise, authorities said in a preliminary report.

Firefighter Jason Cortez, 42, was participating in a training drill Wednesday when he was injured. The married father of two died an hour later at a hospital. Fire officials previously described his death publicly as a “training accident.”

The fire department on Sunday released a copy of the preliminary investigation’s findings to The Associated Press. KNTV first reported it the day before.

The tragedy may have been compounded by confusion about protocols designed to limit the spread of the coronavirus, according to a copy of the five-page report. Only four firefighters — half the typical amount — participated in Wednesday’s “pump drill” exercise meant to train a rookie.

For reasons that aren’t known, Cortez left other firefighters who were dousing a simulated fire on the third floor of a training tower and went to a fire escape, the report stated. There, he “inadvertently” opened a valve — possibly intending to drain water — that did not have a hose connected to it, and a stream flowed out at as much as 100 pounds per square inch pressure.

“The stream of water coming from the (valve) struck him in the chest, knocking him backwards into the fire escape railing, causing him to fall backwards off the fire escape,” according to the report.
