Which material is NOT mentioned as hazardous due to routine testing?

The material referred to in the question, which is not considered hazardous due to routine testing, is test strips. Test strips are commonly used in various applications for measuring pH levels, the presence of harmful substances, or other specific indicators. They are typically designed for safe and straightforward use without posing significant hazards to human health or the environment during routine testing processes.

In contrast, heavy metals, organic solvents, and acids are well-documented as hazardous materials. They often require careful handling, specific safety protocols, and protective measures due to their toxicological profiles and potential health risks. This distinction makes it clear why test strips are not categorized in the same way as the other materials listed.
