The main responsibility of a first responder at a hazardous materials incident is to assess the scene and protect their own safety. This priority is crucial because understanding the hazards present, evaluating the risks, and ensuring personal safety can significantly influence the overall response to the situation. Responders must identify potential dangers such as toxic substances, fire, or explosions, which helps in determining the appropriate actions to take while ensuring they do not become victims themselves.

This focus on safety is essential in hazardous materials responses, as it helps to create a controlled environment in which responders can effectively carry out their duties and work towards mitigating the incident's impact. By prioritizing safety and situational awareness, first responders can make informed decisions on how to proceed, safeguard themselves, and protect the public and the surrounding environment from potential harm.

In contrast, entering contaminated zones without PPE poses a serious risk to the responder’s health and safety. Similarly, the expectation of immediately containing all types of spills is unrealistic; responders must first assess the situation and the materials involved before containment measures are initiated. Lastly, determining disposal methods for hazardous materials is typically a responsibility that falls to specialized personnel rather than first responders, whose primary focus should be on immediate safety and scene management.
