What is one of the best practices for managing unknown materials found in a collection system?

Conducting thorough investigations into the origins of unknown materials is crucial in managing them effectively. This process involves identifying where the material came from, determining its composition and potential hazards, and evaluating its impact on the environment and public health. Thorough investigations ensure that appropriate safety protocols are followed, and necessary actions can be taken based on the nature of the materials discovered.

By understanding the materials' origins, you can make informed decisions about proper handling, treatment, and disposal. This proactive approach helps to mitigate risks associated with unknown substances, ensuring the safety of personnel and compliance with regulations. It also aids in preventing potential contamination within the waste collection system and surrounding environments.

In contrast, immediately labeling materials as hazardous without investigation could lead to unnecessary alarm and incorrect safety measures. Ignoring them based solely on the absence of odor jeopardizes safety, as many hazardous substances may not emit smells. Keeping materials in storage without investigation could also pose risks, as unknown substances may deteriorate or cause contamination over time.
