What is the primary focus of a hazard assessment?

The primary focus of a hazard assessment is to identify potential chemical reactions. This process involves analyzing the substances involved in a situation and evaluating how they might interact under certain conditions. When conducting a hazard assessment, it's crucial to understand the characteristics of the chemicals, including their reactivity, toxicity, and the conditions that may lead to dangerous reactions.

Identifying potential chemical reactions helps responders prepare for and mitigate the risks associated with hazardous materials. This enables them to implement appropriate safety measures and responses in the event of an emergency, ensuring the safety of both personnel and the environment.

In the context of the other options, while determining regulatory compliance, evaluating environmental impact, and assessing safety protocols are all important aspects of safety management and emergency response, they are not the primary focus of a hazard assessment specifically. The core aim is to thoroughly understand the possible interactions and reactions of hazardous substances to better prepare for potential incidents.
