Employees who use or are exposed to hazardous materials must receive training regarding proper use. This training is essential because it ensures that workers understand the risks associated with those materials and the proper methods to handle them safely. Effective training covers a range of topics, including the correct use of personal protective equipment (PPE), safe handling and storage practices, and procedures for responding to spills or exposures. Such knowledge is crucial in minimizing accidents and health risks, ensuring a safer work environment.

While health checks, psychological evaluations, and emergency protocols are also important aspects of workplace safety, they do not directly address the immediate need for employees to know how to properly use the hazardous materials they encounter. Therefore, training is the most fundamental requirement in this context.
