An Airborne supervisor was killed and eight firefighters were injured Sunday afternoon after fire suppression foam was released in a hangar at the Wilmington Air Park, according to a press conference livestreamed by Fox 19.

According to Clinton County Health Commissioner Pam Bauer, who served as Public Information Officer for the conference, on Sunday, Aug. 7 at 1:45 p.m., the release of fire suppression foam was reported at Hangar 1006 at the Wilmington Air Park.

Bauer said that the cause of the foam’s release is unknown at this time but confirmed that it was “not a fire.”

At the time of the initial call, there were reports of “multiple injuries” as well as individuals trapped in a vehicle at the hangar’s entrance and one person “unaccounted for” in an office at that hangar, Bauer said. She said that the individuals in the vehicle were rescued, but the “unaccounted for” employee was killed.

Tim Law, 55, an Airborne Maintenance Area Supervisor, passed away as a result of the incident. Bauer asked that the family’s privacy be respected at this time.

Wilmington Fire and EMS responded to the Air Park at 1:56 p.m. “but had to vacate due to unsafe conditions,” Bauer said. Mutual aid was called to assist, including numerous agencies from Clinton, Fayette, Highland and Warren counties.

“During response operations, two separate responder maydays were issued, and eight responders were transported for medical care due to eye injury, electrocution and other physical injuries,” Bauer said. “Three of those firefighters were transported to Miami Valley Hospital with non-life-threatening injuries. All responders have since been released and have followup appointments today.”

The identities of the firefighters and their departments were not provided.

The Ohio State Fire Marshal’s Office is leading the investigation, Bauer said.

“The City of Wilmington and Clinton County would like to thank the following agencies for support during this response: Wilmington Fire and EMS, Sabina Fire and EMS, Clinton/Warren Joint Fire and EMS District, Chester Township Fire and EMS, Clinton-Highland Fire and EMS, Blanchester Marion Township Fire, Blanchester EMS, Port William-Liberty Township Fire and EMS, Paint Creek Joint Fire/EMS, Lynchburg Fire and EMS, Salem-Morrow Fire and EMS, Washington Court House Fire and EMS, Wilmington Police Department, Clinton County Coroner’s Office, Red Cross, the Highland County Emergency Management Agency along with the Clinton County Emergency Management Agency,” Bauer said.

After Bauer discussed the incident, Air Transport Services Group (ATSG) President and CEO Richard Corrado spoke, as he also thanked the first responders and logistics employees for their efforts Sunday.

“Let us start out by sharing our deepest condolences with the family of Tim Law, who was lost in yesterday’s incident,” Corrado said. “Our priority is on supporting the family and ask that their privacy be respected at this point in time.”

Corrado said that ATSG is “fully cooperating” with the investigation, which he said “will continue as long as it’s needed.”

“All the ATSG companies are focused on safety and reliability throughout our network,” Corrado said. “Safety and training are part of our culture, and incidents such as what happened in Hangar 1006 yesterday validate that focus.”
