In evaluating the judge’s refusal to direct verdicts for City Tank and Old Dominion on negligence, we of course adopt the view of the evidence most favorable to Uloth. Everett v. Bucky Warren, Inc., ante, 280, 282 (1978). We must determine whether "anywhere in the evidence, from whatever source derived, any combination of circumstances could be found from which a reasonable inference could be drawn in favor of the plaintiff.” Poirier v. Plymouth, 374 Mass. 206, 212 (1978), quoting from Raunela v. Hertz Corp., 361 Mass. 341, 343 (1972).
Uloth was injured while working on the Loadmaster 316, a refuse body designed and manufactured by City Tank and Old Dominion. The refuse body had been installed on a used truck chassis supplied by Uloth’s employer, the town of Amesbury, and was used for collecting trash.
The Loadmaster 316 was designed as follows. Running the full width of the truck is a rear step on which the workers ride between stops. The step is approximately two feet from the ground. Twelve inches above the step is a loading sill four inches wide. Just beyond the sill is a "trash hopper” area into which the trash is loaded. A packer blade sweeps through this trash hopper area during the compaction cycle, and pushes the trash into the storage area of the truck. Where the blade meets the loading sill, it creates a shear point where the blade acts like scissors.
The compaction cycle on the Loadmaster 316 is activated by placing the truck in neutral, operating several switches in the cab, and pulling a lever on the side of the truck. The packer blade then descends, reaching the shear point in eleven seconds. The blade returns to its original position and stops. The compaction cycle can be interrupted at any time by disengaging the lever at the side of the truck. Engine noise increases during the cycle.
In Amesbury, two loaders and a driver were customarily sent with the truck, and an effort was made to match an inexperienced loader with one more familiar with the
