Assessing the situation/scene is the essential first step in responding to a hazardous materials incident because it provides critical information necessary for making informed decisions regarding safety and response actions. During this assessment, responders gather data about the nature of the hazardous materials involved, the extent of the incident, potential risks to first responders and the public, environmental factors, and any immediate dangers present.

This assessment helps responders identify the type of hazardous material, determine the appropriate protective equipment needed, and establish an initial response plan. Without this crucial step, responders would lack the necessary information to effectively manage the incident, which could lead to unsafe conditions, ineffective containment, or inadequate public safety measures.

Understanding the overall scene allows for effective coordination with other response agencies and ensures that all actions taken, including containment and evacuation, are done safely and appropriately based on the evaluated risks.
