How to do it |
 |
Identify organic peroxide formers in your chemical inventory. |
|
 |
Store chemicals safely. |
|
 |
Label peroxide formers. |
Chemicals that degrade over time require extra labeling information.
- Tag peroxide formers to make them easily identifiable.
- Make sure chemical labels include the following additional required information:
- Date received
- Date opened
- Date tested (contact the chemical safety officer for testing methods and applicability)
Note: Synthesized material or other laboratory specific operations may present unique circumstances. Contact the chemical safety officer if you have questions.
- Label refillable dispensing containers holding peroxide formers with the fill date.
|
 |
Follow these steps if you discover expired or old peroxide-forming materials. |
Be aware of the passage of time when peroxide formers are in your chemical inventory.
- Review your inventory frequently (including refillable containers) to prevent peroxide formers from reaching unsafe conditions.
- If you find a peroxide-forming material past its expiration date, or more than 1 year past its receipt date, DO NOT OPEN OR MOVE the container.
- Request a hazardous waste collection promptly.
- Label the container to avoid possible inadvertent use until Environment, Health & Safety (EH&S) collects it.
- If the material is very old or shows evidence of conversion to a hazardous status (crystalline materials in or under the cap of ethers, for example), DO NOT MOVE THE CONTAINER.
- Contact EH&S immediately at (858) 534-3660 or 534-2753.
