What is the primary purpose of a work area diagram (chart)?

A work area diagram, also known as a site plan or chart, is primarily used to identify operational quadrants within a lifting area. Its main function is to provide a visual representation of the layout of the site, including critical areas such as the location of the crane, barriers, hazards, and zones where equipment will operate. This diagram helps in planning lifts and ensuring that operations are conducted safely and efficiently by clarifying the operational boundaries and helping all personnel understand where they should be positioned during lifting activities. By mapping out these elements, the work area diagram facilitates better communication and coordination among the crew, ultimately enhancing safety and efficiency on the job site.
