At 10:27 PM on April 5, we were dispatched to the area of Massey Landing at the end of Long Neck Road for a one car MVA. Pot-Nets Security was patrolling nearby and also responded. They reported that all occupants were out of the car but it was leaking fluid. The light tower on Engine 80-5 was used to illuminate the scene as the vehicle was secured and absorbent was placed on the leaking engine coolant. All occupants of the car refused treatment. Twenty-three firefighters were in service for forty-eight minutes for this call.
