Every company is required to prepare a document that assesses all safety and health risks to workers present within its operations, the so-called DVR (Risk Assessment Document). This document must consider all workplaces, all workers and all hazards present. Finally, possible changes that will reduce or eliminate the risks must be defined, also indicating what the priorities of the measures to be taken are. The employer, the person in charge of the prevention and protection service, the competent doctor, and the Workers’ Safety Representative participate in the drafting of the document. By consultation.
