What should responders do when they encounter an unknown substance?

When responders encounter an unknown substance, it is essential to assume it is hazardous and follow standard procedures. This approach is based on the principle of caution and the understanding that many substances can be dangerous or toxic. Recognizing the potential risk helps ensure the safety of responders and the public.

Standard procedures typically involve securing the area, identifying the substance if possible, using appropriate personal protective equipment (PPE), and coordinating with hazardous materials teams or experts. By following these protocols, responders can effectively mitigate risks and handle the situation safely.

Taking this cautious approach is crucial because ignoring the substance or assuming it is harmless could lead to serious health and safety risks. Additionally, just reporting it to local authorities without taking action may not provide immediate safety to those nearby. Thus, assuming the substance is hazardous ensures a proactive and safety-focused response.
