What Can Go Wrong: Failure Mechanisms and Negligence Theories
The question behind most of these cases is simple to ask and hard to answer: what failed, and whose job was it to prevent it?
When an attorney looks at an elevator accident, the first task is usually to identify which component may have failed, because each one leads to a different responsible party. The possibilities include a leveling system that stops the cab out of line with the floor, a door operator that does not reopen, a hoisting rope or sheave (the grooved wheel the ropes run over) that wears or slips, a safety brake that does not engage as designed, and a control system error that sends the cab the wrong command.
Each failure connects to a legal theory. A maintenance failure means a component was not serviced, repaired or replaced when it should have been. That usually points to a premises liability claim against the owner, a negligence claim against the maintenance contractor, or both. Negligent inspection is a related theory: the failure to identify and correct a hazard that was known or could have been discovered.
Product liability holds the makers and sellers of a product responsible when a defect in that product causes injury. In an elevator case, it applies when a component was defective when it left the manufacturer, whether through its design, a mistake in how it was made, or inadequate warnings.
A worn part, a missed service visit and a design weakness can all be part of the same accident. For a person who was hurt, the stake is that focusing on one party too early can leave out another whose role only shows in the service history or the equipment itself, and that equipment can be repaired.
An accident does not by itself prove a defect or a breach of duty. Whether any of these failures occurred depends on the equipment, the service and inspection history, and the circumstances. Questions a person may raise in a conversation with an attorney include what the cab did just before the injury, whether there were earlier problems with that elevator, and which company services it.
