A fire in a Harford County building containing emergency vehicles and the 911 communications center caused moderate damage when intense heat warped a wall and blackened one of the vehicles.
The blaze, which began just before 8 p.m. and was brought under control in 30 minutes, was being investigated last night by the state fire marshal's office. No estimate of the damage was available.
Four firefighters suffered minor burns to their hands while fighting the fire; a 911 dispatcher, who attempted to move one of the trucks out, was being treated for smoke inhalation at Fallston General Hospital.
County spokesman George Harrison said one vehicle was blackened by heat and smoke, and others received minor damage; numerous suits and supplies used by a county hazardous materials unit were destroyed in the building in the 2200 block of Ady Road just north of Bel Air.
The county's 911 service was temporarily rerouted but not interrupted.
