Step-by-step explanation:
The Health and safety regulations assign a legal duty to employers to ensure that employees remain safe and healthy at the workplace. The regulations demand that as reasonably practicable as possible, the employers should provide mechanisms to protect and promote employee welfare and safety.
Under the health and safety regulations, the employer must ensure any potential hazard of work-related nature is eliminated or controlled. Employers must formulate a written health and safety policy statement detailing how they manage health and safety in the workplace. The policy statement, when implemented, goes a long way to improve employees working conditions.
