On sites subject to the obligation to draw up a general co-ordination plan, each company, including sub-contracting companies, called upon to intervene at any time during the work, draws up a specific health and safety protection plan before the work begins. This plan is communicated to the coordinator.
Any company called upon to carry out work on its own, the duration and volume of which exceed certain thresholds, shall also draw up such a plan. It must be sent to the project owner.
