It also sets some boundaries and rules for the employer to consider and follow, in order to protect the safety of the employees. Employers need to evaluate what things can harm the employees and implement the required protections so that no accidents occur. Workers are also trained in terms of safety in the workplace, so that they can identify any risk and avoid it.
