What is typically the first step in responding to a hazardous materials incident?

Identifying the hazardous material involved is critical as it informs all subsequent actions and decisions during a hazardous materials incident. Understanding what substance you are dealing with allows responders to assess the risks accurately, choose the appropriate protective equipment, and implement the correct containment and mitigation strategies. This step is foundational because different materials require varied responses, from firefighting techniques to decontamination procedures. Only by knowing the specifics of the hazardous material can responders effectively assure both their own safety and that of the surrounding community.

While evacuating nearby areas, setting up a containment area, and alerting the public are important actions, they all rely on having accurate information about the hazardous material first. Without this identification, these actions may not be executed effectively or may even pose additional risks.
