What must a lone worker be qualified in?

A lone worker in the context of the Roadway Worker Protection (RWP) Program must be qualified in RWP, NORAC (North American Operating Rules), and Physical Characteristics. This qualification is essential because RWP covers the rules and practices specifically designed to ensure the safety of individuals working on or near the tracks. NORAC provides guidelines for safe operations and communication within the rail environment, which is critical for lone workers who may have limited support. Understanding Physical Characteristics allows the worker to recognize and navigate their working environment effectively, assessing the layout, potential hazards, and safe zones.

This combination of qualifications is specifically tailored to help lone workers operate safely and efficiently, minimizing risks associated with working alone in potentially hazardous situations. Other options, while important in their contexts, do not encapsulate the specific requirements necessary for a lone worker under the RWP framework.
