Define “substitution” as a hazard control method.

Substitution as a hazard control method involves replacing a hazardous material or process with a less hazardous one. This tactic aims to eliminate or significantly reduce the risk associated with a particular hazard by selecting an alternative that poses less danger to workers and the environment. For example, a company might substitute a toxic chemical used in production with a non-toxic alternative, thereby decreasing the likelihood of health risks to employees and minimizing potential environmental impacts.

This method is effective because it addresses the hazard at its source rather than just providing protective measures or procedures, leading to a more sustainable and proactive approach to safety. In contrast, the other choices focus on enhancing policies, personal protective equipment, or training, which, while beneficial, do not address the fundamental issue of the hazard itself.
