The Health and Safety at Work Act is a key piece of legislation in the United Kingdom that aims to ensure the health, safety, and welfare of employees at work. It requires employers to provide a safe working environment, conduct risk assessments, and implement necessary safety measures to protect workers from potential hazards. Under this act, employees also have responsibilities to take care of their own health and safety, as well as that of their colleagues. The act applies to all workplaces and is enforced by the Health and Safety Executive (HSE), which monitors compliance and provides guidance on best practices.
