What are positioning device systems commonly known as?

Positioning device systems are commonly known as work positioning equipment because they are specifically designed to support a worker in a way that allows them to maintain their position while working at heights or in other elevated environments. This type of equipment enables workers to work safely with their hands free, while ensuring that they are securely held in an optimal position to perform their tasks effectively.

Work positioning equipment typically includes devices such as positioning belts, lanyards, and specialized harnesses that provide a stable working platform and prevent the worker from falling. Unlike fall arrest systems, which are intended to stop a fall after it has occurred, work positioning systems focus on allowing a worker to maintain their position safely while they are actively engaged in work.

The other options represent different types of safety equipment but do not accurately describe the primary function of positioning device systems. Safety harnesses can be part of a work positioning system but are also used in fall arrest systems. Fall arrest systems are designed to prevent workers from falling without positioning them. Rescue equipment is specifically meant for retrieval in emergency situations and is not focused on positioning during work tasks.
