Occupational safety and health (OSH) is a multidisciplinary field concerned with the safety, health, and welfare of people at occupation. These terms also refer to the goals of this field. In common-law jurisdictions, employers have a common law duty (also called duty of care) to take reasonable care of the safety of their employees. Statute law may, in addition, impose other general duties, introduce specific duties, and create government bodies with powers to regulate occupational safety issues: details of this vary from jurisdiction to jurisdiction. And us COH&S (Centre for Occupational Health & Safety) are a centre which provides training courses to ensure the safety of employees at various workplaces.
