• B. Level 1: Awareness
• C. Perception
• D. Level 1: Detection

Answer: (C)

Level 1 of Situational Awareness is perception—the act of noticing and identifying elements in the environment within a given time and space. In a hazmat situation, this means observing cues like odors, leaks, placards, container shapes, spill patterns, equipment, people, and wind direction. This initial noticing provides the data you need to understand what’s happening and to build toward deeper understanding and anticipation. Perception is the best descriptor for this first stage because it focuses on actually sensing what’s present; other terms like “awareness” or “detection” don’t map as precisely to the defined first level.
