Name two common indicators of a hazardous materials incident.

Unusual odors and visible vapors or clouds are critical indicators of a hazardous materials incident. In many instances, the presence of strange or strong smells can signal the release of hazardous substances, which may pose risks to health and safety. Similarly, the appearance of vapors or clouds can indicate the dispersion of hazardous materials in the atmosphere, potentially affecting air quality and safety in the surrounding area.

Identifying these signs is essential for first responders and HazMat teams, as they contribute to an initial assessment of the situation and inform subsequent actions, such as evacuations or containment measures. Recognizing these indicators allows responders to quickly ascertain the nature of the hazard and take appropriate measures to protect themselves and the public.
