Overview
- Pittsburgh EMS reported several emergency alerts, including ones triggered by social-media posts showing people on the ice.
- Crews observed dozens of people, including children, walking on the frozen Allegheny River over the weekend.
- EMS Chief Amera Gilchrist said roughly 4 to 5 inches of solid, clear ice is needed to support an adult, yet river thickness varies with no reliable way to gauge it.
- Falling through can induce cold-water shock within seconds, with fast-moving currents and hypothermia quickly escalating the danger.
- Ice rescues expose trained divers and responders to significant risk, and in Philadelphia police logged more than a dozen calls and say going onto city rivers is illegal.
