What is the main duty of a worker?

• A. Inspect quality of materials.
• B. Carry out construction work with the required skills and appropriate training or supervision to do it safely and without health risk.
• C. Prepare designs.
• D. Coordinate subcontractors.

Answer: (B)

The key point is that on site, each worker must perform their tasks with the appropriate skills and training, or under supervision, so the work can be done safely and without health risk. This focus on competence and safe practice protects the worker and others from injuries and hazards that arise in construction environments. Tasks like inspecting material quality or coordinating subcontractors belong to other roles—quality inspectors and engineers or site managers—not the everyday duty of a worker carrying out construction work. Preparing designs is the responsibility of designers or engineers. So the best answer centers on carrying out the construction tasks safely, using the right training or supervision.
