Which of the following is NOT one of the work site parties defined by OHS in the material?

• A. Contractor
• B. Supplier
• C. Worker
• D. Client

Answer: (D)

Who counts as a work site party? The material defines the groups that have direct safety duties on the work site—those who actively participate in planning, directing, and carrying out safe work. This typically includes the contractor, who runs the on-site activities and safety programs; the supplier, who provides equipment and materials with safety considerations; and the worker, who performs the tasks and follows safety procedures. A client, while important as the project’s customer or requester, is not listed as one of the on-site safety parties in this material. Their role is external to the day-to-day safety duties defined for on-site parties, so they aren’t included in the defined work site party list.
