Frequently Asked Questions

Kemibrug is a joint IT system for Aalborg University, the University of Copenhagen, the University of Southern Denmark and the Technical University of Denmark. Since 1988, we have produced safety data sheets for dangerous substances and materials in use or under the consideration for use. The safety data sheets are written material to support the local risk assessments.

Even if a substance is included on the Harmonized List, this classification represents the minimum labeling requirements. Additional Hazard-phrases may be added if there is documentation to support this.

In the event of a discrepancy between the supplier’s labeling and the CLP regulations, Kemibrug will contact the supplier for the preparation of a safety data sheet which is in accordance with Kemibrug’s assessment. Kemibrug is an impartial party and we evaluate the substances according to the data to which we have access. The suppliers will sometimes maintain their assessment, which will give the difference in the labeling. For substances with CAS no., a joint KBA is produced, collecting information from several suppliers and finding the one that best matches Kemibrug’s assessment. Products, without a CAS no., are produced based on a specific SDS from a named supplier, and the KBA refers directly to this supplier. Therefore, there may be several KBAs with the same mixture, but with different labeling.

In Kemibrug, the pH value field is primarily used to enter information under ‘Physical and chemical data’. In addition, the pH value affects the information provided under the ‘Environment’ section, as the pH value can have significant effects on the environment. This helps the assessment of how a substance or mixture could potentially affect the environment based on its acidity. For example, a substance can affect the water environment due to its pH value.

No, it is not necessary to register yourself as ‘responsible’ to create a label in Kemibrug. One can complete the label by simply adding the necessary labeling information. Additional information about the ‘responsible’ role is not necessary for this process. However, it is recommended to use the free text fields to enter who made the label.

The information in the table in section D can be used to prepare substitution explanations and other security measures. Furthermore, there may be information on incompatibility, flash point, solubility and environmentally harmful properties, which can be usable in the local risk assessment.

The CAS number is a unique identifier that helps to avoid misunderstandings between the customer and the chemical consultant who manufactures the KBA. Chemical compounds may be known by various names, including trade names and systematic names.

When Kemibrug changes a KBA, for example due to changes in legislation, the change is not marked in the KBA at the place where it was made. Instead, a note line is added in the KBA under last revised indicating the date of the statutory adjustment and details of what has changed. If you subscribe to the KBA, you will receive an email with the changes directly

If you have many orders in the system, you can prioritize them such that you get the most important ones first. The prioritization can be based on several factors, including whether the substance causes harm, is used frequently or in large quantities, is used in problematic work processes (such as evaporation or aerosol formation), whether the substance has special labeling or legislative requirements, has special physical/chemical properties, such as risk of peroxide formation, or if there is insecurity when working with the substance in question. You can write your priority in the comments field when you order or via the cas-Kemibrug mailbox afterwards.

For endocrine-disrupting substances, EUH phrases are used instead of the regular Hazard phrases. In section B, it can say e.g. ‘The substance is recognized as having endocrine -disrupting effects’.

The ‘Default value’ button in Kemibrug is used when you do not have a specific value for boiling point or flash point available. By using this default value, the CLP calculator can continue to calculate the correct labeling of the mixture. It is important to note that this default value does not necessarily apply to all liquids, but it offers a temporary solution so that the calculation can be performed.
