Evacuation should be considered during a HAZMAT incident when there is an immediate threat to public health or safety. This situation generally arises when hazardous materials are involved that could lead to exposure or harm to individuals nearby, including the general public and first responders. Factors that can indicate an immediate threat may include releases of toxic gas, explosive materials, or other hazardous substances that pose a rapid risk of injury or illness.

Prioritizing public safety is critical in HAZMAT responses, and immediate evacuation can prevent exposure and save lives. Taking prompt action in potentially dangerous situations reflects an understanding of the urgency that often accompanies these incidents. Other considerations like the potential for a secondary hazard or the timing of responders' arrival may influence operational decisions but do not directly dictate the necessity of evacuation as urgently as the immediate health and safety threat does. Similarly, the identification of the pollutant, while important for managing a response, does not negate or outweigh the need for immediate action in the face of imminent danger to the public.
