What should be the first step when approaching a hazardous materials situation?

When approaching a hazardous materials situation, the foremost priority is to assess the scene for safety and hazards. This step is crucial because it allows first responders to identify potential threats, determine the nature and extent of the hazardous materials involved, and evaluate environmental factors that could impact safety. By understanding the situation's dynamics—including the presence of hazardous substances, wind direction, potential sources of ignition, and the level of risk to both personnel and the surrounding public—responders can make informed decisions about the necessary actions to take.

Once the scene's safety and hazards have been assessed, appropriate protocols can be initiated, which may include communication with team members, containment procedures, or evacuation processes. Prioritizing scene assessment ensures that responders do not put themselves or others in unnecessary danger and sets the foundation for effectively managing the incident.
