What should a security officer do if they are uncertain about a substance at a hazmat incident?

In a hazmat incident, if a security officer is uncertain about a substance, it's crucial to prioritize safety while gathering information. Remaining at a safe distance and observing allows the officer to monitor the situation without exposing themselves to potential hazards associated with unknown substances. This approach not only protects the individual but also enables them to provide useful information to emergency responders when they arrive.

Observing from a safe distance can help in identifying any visible indicators of the substance's nature, such as color, behavior, or the presence of vapors, while maintaining a safe perimeter. This method aligns with best practices in hazardous materials response, emphasizing the importance of safety and caution over making hasty decisions or assumptions that could compromise personal safety or lead to incorrect conclusions about the incident. By observing, the officer remains a valuable resource for information without putting themselves or others at risk.
