Which of the following is a primary action for private EMS response to hazardous materials?

The primary action for private EMS response to hazardous materials is to ensure the safety of yourself and others. This is crucial because hazardous materials can pose significant risks not only to victims but also to first responders. Before any action is taken, it is paramount for EMS personnel to assess the situation and secure the scene to prevent further harm.

By prioritizing safety, responders can evaluate the hazards present, utilize proper personal protective equipment (PPE), and establish a safe perimeter to keep bystanders and other personnel out of danger. Only after confirming safety can they move on to other actions like patient care or triage. In any emergency setting involving hazardous materials, where unpredictable elements may be involved, ensuring the safety of all is the first and most critical step. This focuses the response on minimizing risk and effectively managing the situation.
