What should be the first priority at any hazardous materials incident?

The first priority at any hazardous materials incident is the safety of responders and victims. In emergency situations involving hazardous materials, whether it is a chemical spill, fire, or any other dangerous scenario, ensuring the safety of all individuals in the vicinity is paramount. This includes evaluating potential risks and taking immediate actions to protect people from exposure to harmful substances.

Emergency responders must assess the situation to identify hazards and take necessary precautions, such as wearing appropriate personal protective equipment (PPE) and ensuring that victims are out of harm's way. If responders do not prioritize safety first, it could lead to injuries or fatalities, making the situation far more complicated and dangerous.

Other aspects, such as containment of the material, evacuating the area, and securing the perimeter, are critical steps that follow the initial assessment and safety measures. While they are essential for managing the incident effectively, they cannot take precedence over the immediate need to protect lives. Therefore, prioritizing safety lays the foundation for all subsequent actions at a hazardous materials incident.
