    • Contractors should take all appropriate precautions to protect persons present at, or in the vicinity of, a construction site from all risks which may arise from such site. Contractors should provide its workers with necessary Safety Apparel/Equipment while performing its task. Apparel such as hard hats, safety belt googles should be provided depending on the nature of work.

    • Contractors should arrange for regular safety inspections by competent persons at suitable intervals of all equipment, tools, machinery, workplaces and systems of work under the control of the contractor at construction sites in accordance with national laws, regulations, standards or codes of practice. As appropriate, the competent person should examine and test by type or individually to ascertain the safety of construction machinery and equipment.

    • When acquiring equipment or machinery, contractors should ensure that it takes account of ergonomic principles in its design and conforms to relevant national laws, regulations, standards or codes of practice and, if there are none, that it is so designed or protected that it can be operated safely and without risk to health.

    • Contractors should provide such supervision as will ensure that workers perform their work with due regard to their safety and health.

    • Contractors should assign workers only to employment for which they are suited by their age, physique, state of health and skill.

    • Contractors should satisfy themselves that all workers are suitably instructed in the hazards connected with their work and environment and trained in the precautions necessary to avoid accidents and injury to health.

    • Contractors should take all practicable steps to ensure that workers are made aware of the relevant national or local laws, regulations, standards, codes of practice, instructions and advice relating to prevention of accidents and injuries to health.

    • Equipment, tools, machinery or workplaces in which a dangerous defect has been found not be used until the defect has been remedied.

    • Where there is an imminent danger to the safety of workers, the contractor should take immediate steps to stop the operation an evacuate workers as appropriate.

    • On dispersed sites where small groups of workers operate in isolation, contractors should establish a checking system by which it can be ascertained that all the members of a shift, including operators of mobile equipment, have returned to the camp or base at the close of work.

    • Contractors should provide appropriate first aid, training and welfare facilities to workers and, whenever collective measures are not feasible or are insufficient, provide and maintain personal protective equipment and clothing. Contractors should also ensure access for workers to occupational health services.
