Which one of the following is NOT among the steps of awareness in handling hazardous materials?

The correct answer signifies that "Assessment" is not a part of the steps typically recognized in handling hazardous materials. The steps of awareness in hazardous materials situations generally focus on recognizing the presence of hazardous materials, identifying what they are, and notifying the appropriate authorities or response teams.

The step of recognition involves being able to determine when a hazardous situation is present, while identification means pinpointing the type of hazardous material involved. Notification is crucial as it involves informing the right personnel about the hazards detected, ensuring that emergency response can be initiated appropriately.

While assessment is an important part of many safety and emergency response protocols, in the specific context of handling hazardous materials at the awareness level, it isn't classified as one of the foundational steps. Instead, awareness focuses on recognition, identification, and notification, which are essential for initial responders to take appropriate and timely action.
