The forklift had a Hippo Hopper 2 yard self-dumping hopper (model HH32, serial no. 53906) attached to the forks, and the employee was using the forklift to convey tire refuse to refuse container. At approximately 8:42 p.m. twilight conditions existed following the sunset at approximately 8:20 p.m. as the employee approached the north metering bin while operating the forklift.

The employee then drove the forklift and made a couple of turns and while turning to the left with the hopper elevated, the forklift tipped over onto the right side, and the employee was pinned between the forklift and the ground. The employee was killed from the crushing injuries.
