The facility maintains a Chemical Inventory List or equivalent records, for all production chemicals.
The chemicals that are purchased by a facility must be recorded in the CIL and this must be updated on a regular basis for additions or deletions in the chemical inventory.
Chemical Inventory List (CIL)
The Chemical Inventory List (CIL) should be managed and updated by the designated Chemical Responsible Person or Team within the facility. This responsibility includes:
- Inputting all relevant technical data into the relevant CIL columns.
- Co-ordinating with the purchase department to obtain information on newly purchased chemicals.
- Updating the list regularly to reflect any new chemical purchases.
- Conducting a regular assessment of the physical stock recorded in the CIL.
This process ensures that the CIL remains a comprehensive and up-to-date record of all chemicals present in the facility, supporting effective chemical management and safety protocols.
The ZDHC CIL template should be completed with information in three columns: foundational, progressive and aspirational.
Record lot/batch numbers of all chemicals purchased by the facility
Lot/batch numbers
Record lot/batch numbers of all chemicals purchased by the facility in the Chemical Inventory List (CIL) and in the production recipe sheets/logs.
Recording lot/batch numbers
Chemicals (formulations, commodity chemicals and solvents) should be purchased with the lot or batch number from the chemical supplier. This information should be recorded in the Chemical Inventory List (CIL) for each chemical listed.
The batch or lot number of the chemical used in the production of an article/product should also be recorded in the recipe sheets/log books of each production batch so that it can be traced back from the finished article to the chemical inventory.
This data helps in undertaking a root cause analysis of any ZDHC MRSL non-conformity of substances in the final article or wastewater or sludge testing.
