What is a common guideline for handling hazardous materials?

Following Material Safety Data Sheets (MSDS) is indeed a common and crucial guideline for handling hazardous materials. MSDS provide detailed information about the properties and potential hazards of a chemical substance, including safe handling practices, necessary Personal Protective Equipment (PPE), and emergency procedures in case of exposure or spills.

By adhering to the guidelines laid out in the MSDS, medical assistants and other healthcare workers can ensure they are adequately protecting themselves and others from the dangers associated with hazardous materials. This includes understanding how to store, use, and dispose of these materials safely, thereby minimizing the risk of accidents and health hazards.

The other options do not adhere to safety protocols. Disposing of hazardous materials in regular trash can lead to serious environmental and health risks, while storing them in a locked cabinet is important for safety, but it is fundamentally crucial to know how to handle the materials correctly first. Leaving unmarked containers open is highly unsafe, as it can lead to confusion and accidental exposure or chemical reactions.
