Holding chemicals are materials tin which we need additional information to verify. When the contents of a container are unconfirmed, safe handling, storage, and disposal become difficult. A fee must be paid to have these materials analyzed and identified. A $75 per container charge (irrespective of the size of the container) is incurred for disposal.
Prevent the generation of holding chemicals by:
- Ensuring that all chemical containers are labeled
- Periodically checking the labels for integrity
- Using full chemical names instead of abbreviations and symbols
- Disposing of unneeded materials
How to prepare your holding container for disposal:
- Visual inspect before handling, look for:
- Marks or symbols denoting hazardous characteristics
- Bulging and collapsing container
- Crystal formation surrounding the lid or cap, within the bottle neck, and/or within the liquid
- Do not move or open the container if crystal formation or bulging is evident, the material may have produced an unstable environment.
