Also substances that are part of mixtures must be identified and accounted in chemicals inventories.
Chemicals inventory is an overview of all chemical substances and mixtures used in company.
Chemicals inventory is an overview of all chemical substances and mixtures used in company. It composes all information on identification, classification, storage, safety and other information that is relevant for safe handling of hazardous chemicals and having an overview of their flows in the company. As such, chemicals inventory can be seen as one of cornerstones of conducting a good chemicals management practice.
Chemicals inventory need to be kept in all companies that are professional or industrial users of hazardous chemicals to comply with legal requirements.
But the inventory is not necessary only because the law requires it. It provides several useful features for the company:
- helps to create a systematic frame for collecting information on hazardous chemicals;
- brings out the bottlenecks;
- gives an overview on the use of hazardous chemicals;
- provides information for the company's future strategies and development plans;
- helps to anticipate problems;
- allows you to quickly find the necessary information.
There should be sufficient information to clearly identify substances that are being used and/or produced, their amounts, hazard information and handling conditions. The following sections should be included in inventory:
- Name of the product – name of substance or mixture, as identified on the label, or in technical documentation (in safety data sheet, SDS). This can be a commercial name and the one most commonly used in internal communication within the company or between company and supplier/client.
- Composition of the product – identification of components of the mixture or chemical name of the pure substance by IUPAC nomenclature. This section should also contain information on percentage of each ingredient in the product and CAS/EC numbers of each ingredient – all essentail information that can be found in SDS to properly identify composition of a chemical mixture.
- Classification and hazard identification – hazard classification of each substance or component in mixtures according to the CLP Regulation. It should include hazard class and relevant Hazard statements and Precautionary statements.
- Use of the product – section should contain information on purpose of use (technological process, formulation of new products, etc.) of each chemical product and used amount in each process/product (each year)
- Storage – information on storage method (container, what sort of packaging, etc.), amount (volume stored simultaneously) and storage location (warehouse, storage place identification number, etc.)
