1 p.m.: Residents of the E.D.G.E., a workforce housing complex for Copper Mountain Resort employees, have started reentering the building after a structure fire set off alarms there Tuesday, Dec. 2, around 10:15 a.m.

Red, White & Blue Fire Protection District public information officer Matt Benedict said the fire officials are not allowing residents to go to the third and fourth floors of the building as of 1 p.m. Dec. 2 because responders are still working to clear smoke out of those floors.

The fire did not spread from the room in which it started, Benedict said, although smoke did spread throughout the building.

“Hazards have been eliminated,” Benedict said. “We’re just being cautious. Making sure everything’s ready for people to be back in.”

Benedict said fire officials anticipate the fire will only displace the residents of the room in which it started and “worst-case scenario” one adjacent room.

Summit Fire & EMS public information officer Steve Lipsher said around 400 people live in the E.D.G.E. He said the cause of the fire is still under investigation. The occupants of the unit where the fire started were not present when it did, Lipsher said, but they did return to the building to be interviewed by investigators.

The fire triggered the building’s alarms, and Copper Mountain security was the first to the scene and confirmed there was a fire in the building, Lipsher said. Seven units of firefighters responded, Lipsher said, as it was a two-alarm fire, meaning Summit Fire & EMS received support from the Red, White & Blue Fire Protection District.

“We send everybody we have in our district, and then Red, White & Blue comes and supplements us on the fire scene,” Lipsher said. “They also cover our district for us, for any other emergencies that may happen simultaneously.”

One fire engine had a rapid intervention team, Lipsher said, which is a group of firefighters in emergency rescue gear that wait outside the building “ready to go at a moment’s notice” to rescue firefighters in the building that might be in trouble.

Lipsher credited Copper Mountain’s housing department and the Summit County Sheriff’s Office for helping fire officials evacuate the building. He said the fire did not result in any injuries, and within the room the fire started, it did not spread beyond its origin.

“It was confined to whatever caught on fire and the immediate vicinity,” Lipsher said. “I am optimistic that this is the type of thing that is going to be rehabilitated and returned without being a tremendously long ordeal.”

11:15 a.m.: A crowd has gathered outside of the E.D.G.E., a workforce housing complex for Copper Mountain Resort employees, following a structure fire Tuesday, Dec. 2, around 10:15 a.m.

Summit Fire & EMS public information officer Steve Lipsher stated the building had a fire in one room and was safely evacuated. He said the problem was addressed and that more details will be provided soon.

Red, White & Blue Fire Protection District public information officer Matt Benedict stated the fire was contained to one room but that they are investigating how far the smoke might have spread. He noted there are no known injuries at this time.

“We have smoke throughout many floors at this point, so a lot of what we are doing right now is just making sure that is mitigated. There’s still an investigation going on to make sure it stayed in one room. We don’t know that for sure right now.”

Benedict said the size of the building caused multiple agencies to get called to the scene since there was a potential for a risk for a “huge potential loss.”

As of 11:15 a.m., the situation was still not in an “emerging” phase but not in a stable phase, meaning there’s still a potential that the fire has spread.

“It was contained to one room,” Benedict said. “We are hoping it stays that way.”
