Firefighters battling a blaze in a Warren County house Friday morning suffered injuries when they fell through the floor, officials said.

Crews responded to a residential structure fire just before 7:30 a.m. Friday at 24 Markham Farm Road in the Blue Mountain Area, according to information released that afternoon by Warren County Department of Fire and Rescue Services Chief Richard Mabie.

Crews arrived on the scene and reported smoke coming from the attic and throughout the first floor of the home, the media release notes. Firefighters forced entry into the home to attack the blaze and to conduct search-and-rescue efforts.

The first-story floor collapsed and two firefighters fell through into the basement, according to the release. Members alerted crews by transmitting a call of “mayday firefighter down.” Both firefighters came out of the basement on their own. Emergency medical technicians treated the firefighters at the scene for non-life threatening injuries then transported the crew members to Warren Memorial Hospital for further evaluation. The firefighters were treated and released from the hospital and then sent home, Mabie stated in an email.

Firefighters brought the blaze under control in roughly 15 minutes, the release states. The fire caused an estimated $85,000 in damage. No occupants were on the property at the time of the fire.

The Frederick County Fire Marshals Office Canine Division assisted the Warren County Fire Marshals Office. The cause of the fire remains under investigation by the Warren County Fire Marshals Office.

Mabie ordered a detailed review of the incident response, action plan and the “near-miss” of two emergency responders who fell through the collapsed floor. As a result, the Fire Marshal’s Office and the county department’s Training Division plan to complete a Significant Incident Review and train all members on its findings.

The department asks anyone with information on the incident to contact Fire Marshal Gerry Maiatico at gmaiatico@warrencountyfire.com or 540-636-3830.

Online property records for Warren County indicate that Alfonso Elia has owned the single-family home since 2011. The house was built in 2006, according to the county records.
