Which of the following is a primary focus of health and safety in construction?

Focusing on the well-being of workers is a primary aspect of health and safety in the construction industry. Health and safety protocols are established primarily to prevent accidents, injuries, and illnesses on the job site. Protecting workers ensures that they can perform their tasks effectively and without undue risk to their physical and mental health. It's essential for employers to implement safety measures, provide adequate training, and maintain a safe work environment to promote the overall health of their workforce.

In contrast, minimizing labor costs, ensuring quality of materials, and accelerating project schedules do not directly correlate to health and safety concerns. While these factors are important for a project's success and can indirectly influence worker safety, they are not the fundamental priorities when it comes to creating a safe construction work environment. The main goal of health and safety measures is always to safeguard the lives and health of the workers on site.
