Where should unwanted chemicals, biological specimens, and idle equipment be stored?

Unwanted chemicals, biological specimens, and idle equipment should be stored in designated areas that prioritize safety and compliance with relevant regulations. Storing them on the lab bench is not ideal; it can create clutter and increase the risk of accidental spills or contamination.

The correct practice involves keeping these items in appropriate storage areas designed to contain them safely. For instance, chemicals should be stored in a chemical storage cabinet that is specifically designed for that purpose, ensuring they don’t pose a risk to personnel. Biological specimens typically require cold storage or biohazard containment, while idle equipment should be organized in an area where it does not obstruct work or create hazards.

Storing dangerous items in the hood, under the sink, or in an unlocked cabinet poses significant risks. Hoods are designed for ongoing work with hazardous materials, not for storage; placing items under the sink can lead to contamination or hazards if the sink leaks; and unsecured cabinets provide no protection and could lead to unauthorized access or spills. Thus, proper storage practices are essential for maintaining a safe laboratory environment.
