Regarding Chemical Waste Disposal and Secondary Containers
Date: 4/2/2026
We have had repeated instances of unknown liquid being found inside/on secondary containers for chemical waste bottles, and on chemical waste bottles, some photos shown below. This is unacceptable and must stop immediately.
It is a serious safety hazard for other users, Nano3 staff, and EH&S personnel and can lead to dangerous exposure. Every user is responsible for ensuring they are not putting others at risk of dangerous chemical exposure.
Immediate compliance with the following procedures is required:
- No Bottles in Sinks: Waste bottles must not be placed inside the sink for storage. (you may briefly place the waste bottle in the sink for chemical disposal)
- Use the provided funnels carefully to prevent spills or overflows.
- Clean up any drips or residues immediately and completely.
- Do not leave any drips, puddles, or residues on the bottle, or in/on the secondary container.
- Do not leave funnels resting on waste bottles.
- Return the waste bottle (inside its secondary container) to its designated location within the storage cabinet.
Thank you for your immediate cooperation.
