What is necessary for an inspector when dealing with unknown substances?

When dealing with unknown substances, it is crucial for an inspector to document the findings accurately. This is important because proper documentation ensures that there is a clear record of the substance in question, the context in which it was found, and any actions taken in response to it. Accurate records are essential for safety, compliance with regulations, and providing information for further investigation or response by the appropriate authorities.

In situations involving unknown substances, assuming safety or ignoring a potential hazard can lead to serious consequences. Additionally, public input does not provide the technical expertise necessary to assess the risks associated with unknown substances, which is why it is not a suitable response in such scenarios. The most responsible and professional approach is thorough documentation, which supports risk assessment and future decision-making.
