C- SAFETY AND SECURITY ON WORK SITE
1. The contractor must take any kind of safety measure to prevent workers, plant and local people from being exposed to
any accident or damage due to the works to be performed on site as the work continues (until provisional acceptance).
The contractor shall be liable for covering any potential loss and damage arising from the failure to take adequate
safety measures on or around site. The contractor must take all necessary measures and follow the instructions of the
inspection organization to avoid the occurrence of accidents, losses and damages. Additionally, the contractor must
train employees on the procedures and measures for protection against potential accidents caused by equipment and
machines used on site. All of the expenses relating to safety and protection measures practiced of the contractor’s own
accord shall be borne by the contractor itself. If any complaint is received from the plant management or is found by
the inspection organization in connection with the loss and damage caused by the contractor, the cost of the resulting
