What is the first step in the hazardous materials response process?

Identifying the presence of hazardous materials is the essential first step in the hazardous materials response process because it lays the groundwork for all subsequent actions. Without accurately confirming the existence and type of hazardous materials involved, responders cannot evaluate the risks or take appropriate measures to protect themselves, the public, and the environment. This step involves assessing the scene, checking for labels, placards, and other indicators, as well as utilizing monitoring equipment if necessary. Knowing what hazards responders are dealing with is critical for making informed decisions about evacuation, communication, and safety planning, ultimately ensuring an effective and safe response.

The other steps, while important, depend on the initial identification of hazards to ensure they are relevant and appropriate to the specific situation.
