The southbound lanes of Pennsylvania Avenue from Foothill Boulevard were closed Friday due to an explosion in one unit of an apartment complex in the 4400 block of Pennsylvania Avenue.

Someone in the apartment was doing some fumigation work in a unit.

“What could have happened was the fumigation met with an ignition source like a pilot light,” said Glendale Fire Dept. Battalion Chief Thomas Marchant Friday while at the site. “We mitigated any hazards that existed when we got here.”

Both the gas and electricity were shut off for the entire complex and all residents were evacuated.

A senior building inspector from the city of Glendale Building Dept. was called to address any building structure problems before residents were allowed to return to their units.

“One man was transported to USC VHH [with minor injuries],” said Glendale police Sgt. Ruiz.

GFD responded with three engines, one truck, two ambulances and a battalion command vehicle. Glendale police also responded.

Glendale fire department  investigated the incident.
