Go inside Philadelphia's Office of Emergency Management operation | Exclusive

PHILADELPHIA (WPVI) -- From managing issues with infrastructure and protecting the vulnerable population during the deep freeze to planning for the city's biggest events, the Office of Emergency Management is there.

Action News got a look at the OEM mobile command center, a rolling hub designed to deploy at a moment's notice for emergencies and major public events.

"We're actually on the city's mobile command post. It's called Command Post One," said OEM Director Dominick Mireles.

The vehicle has served as a central base at incidents such as the I-95 collapse and at large gatherings, including July 4th celebrations on the Parkway.

The OEM warehouse is stocked with essential supplies to support responders and residents during crises. "It's not glamorous, but we have the basics covered. There's plenty of cots, walkers and wheelchairs," said Mireles.

The ongoing extended code blue has added pressure to the agency's operations. Officials said the weekend alone saw 12 house fires, many linked to increased strain on power systems.

"Space heater things need to be plugged into a wall. They can't be plugged into a surge protector or extension cord," said Mireles.

Along with power and water concerns, the cold snap has renewed calls for residents to prepare for emergencies at home. "This sounds scary: be prepared to be on your own for three days at home," Mireles said.

OEM teams are also monitoring waterways as frigid temperatures freeze rivers.

"We're pretty much 90 to 99% ice coverage," said Mireles.

Now OEM is preparing for any flooding once the thaw begins.

Even as they manage winter hazards, the agency is already planning for a busy summer filled with large-scale events.

"Because of the magnitude of events, because we are in storm season, all of the what-ifs that are out there, we'll be coordinating 24/7," said Mireles.
