"Drilling Truck" Fire at Lehigh

Local Box 8-7. At 11:30 hrs., Carroll County 911 dispatched Station 8 for a "Drill on Fire" in the quarry at Lehigh Portland Cement Company. Engine 81 responded, followed by Engine/Tanker 82 and Paramedic 89, since it was known that a "Drilling Truck" on fire would require more than 1000 gallons of water to extinguish. Initially, directions from CCECC 911 and calls direct from Lehigh conflicted, so Engine 81 went in by the Main Street Entrance while Engine/Tanker 82 went in by the Clemsonville Entrance.

After a 6 minute response time into the 9th level of the quarry (450' below grade), Engine 81 arrived to find a "Drilling truck well involved". The crew quickly deployed an 1 3/4" Pre-Connect and a 2" Pre-Connect to begin the extinguishment of the fire. Engine/Tanker 82 arrived just after the lines were deployed and assisted with 'backing-up' the attack line crews and providing additional water supply.

Safety became an issue early on since the drilling trucks tower had already begun to lean; first to the left, then to the right (viewed from the front of the truck); as the tires and hydraulic jacks began to give-way. As the fire was 'knocked-down', the 1 3/4" pre-connect was switched to operate as a foam line with 3% Aqueous Film Forming Foam (Class B: AFFF) due to the large amount of gear and hydraulic oil that was burning on and under the truck (multiple hydraulic lines had burnt through from the rigs drilling unit).

At 11:56 hrs., Chief 8 advised the fire was out and that crews would be remaining on-scene for mop-up. A total of 3,000 gallons of water and nearly 15 gallons of AFFF was used to extinguish the fire. No injuries were reported, but the "Drilling Truck" sustained heavy damage to the 'drilling rig' and under chassis.

Units returned to the station by 12:53 hrs., but it took another 2 1/2 hours to clean-up the apparatus, turn-out gear, hose and tools used to extinguish the fire.
