Two firefighters were injured after a tanker from the Dunkirk Volunteer Fire Department overturned Saturday morning.

Around 8:05 a.m., deputies from Calvert County Sheriff’s Office responded to Robinson Road in Huntingtown for an overturned tanker.

The tanker, which was full with 3,000 gallons of water, was responding as the primary water supply to a house fire in Huntingtown.

Firefighters Lt. Marty Sealey and Lt. John Faulkner Jr. were injured in the crash. They were both transported to the hospital in critical condition, but stable condition.

Lt. Sealey has been released from the hospital and Lt. Faulkner is expected to be released Saturday night.

A tire “blowout” appears to be what caused the tanker to crash, the Calvert County Sheriff’s Office reported. Deputies continue to investigate what caused the tread to completely separate from the wheel.

The original house fire has been put out and is under investigation.
