An early morning fire in Jersey City reached five alarms, affecting at least three multi-family homes and leaving seven firefighters with injures.

The fire began around 2:30 a.m. in a first-floor bedroom at a building located at 10 Irving St., just off Central Avenue near Washington Park.

The fire chief says the seven firefighters suffered non-life-threatening injuries. Four were injured when a power line fell on a ladder truck, shocking them. They were all sent to a hospital and are expected to be OK.

“As we were starting to advance lines, powerlines came down,” says Chief Steven McGill. “They burned off the side of the building and it energized one of the fire trucks, which injured four of the firefighters, one captain on that apparatus.”

Other firefighters injured included a minor burn and heat exhaustion. Two residents declined medical attention. 

All 18 residents escaped unharmed, but one resident was very emotional after her and her husband jumped about six feet from their kitchen window to safety. She also cannot find her four cats.

There is no word yet on cause.
