What is the first step in HAZMAT spill response?

The initial step in responding to a hazardous materials spill is discovery. This involves recognizing that a spill has occurred and assessing the situation to ensure safety. Discovery is vital as it sets the stage for the subsequent actions. It helps identify the type and extent of the hazardous materials involved, and it allows responders to determine immediate hazards to personnel and the environment, which is crucial for effective incident management.

Once the spill has been discovered, proper notifications can then be made to ensure that help is on the way and appropriate containment, cleanup, and decontamination efforts can be initiated. Each of these subsequent steps is critical, but none can effectively occur without first recognizing and assessing the spill.
