Health & Safety Responsibilities
Managers and supervisors carry both legal and company responsibilities for ensuring the health and safety of their employees, those under their control, and those who might be affected by the work undertaken, i.e. public, visitors and employees of other organisations. This includes briefing individuals working for them and ensuring there is the necessary understanding, competence and application of requirements to work safely and without harming the environment.
Employees are responsible for ensuring they fully understand the health and safety risks involved in their work activities and their responsibility to apply the controls needed to manage those risks to acceptable levels.
