Why is it important to avoid assumptions at hazardous material incidents?

Avoiding assumptions at hazardous material incidents is crucial because making incorrect assumptions increases the potential for exposure. In such scenarios, the substances involved can be highly toxic, flammable, or otherwise harmful. If responders assume they understand the nature of the hazard without verifying it, they may inadvertently place themselves and others at risk by approaching the situation with an inadequate understanding of the necessary precautions or protective measures.

For example, if responders assume that an unknown substance is safe without proper identification or assessment, they might enter a contaminated area without appropriate personal protective equipment, which could lead to serious health consequences. Ensuring accurate information and assessments before taking action helps to maintain safety and mitigate risks effectively.
