Hazardous Substances Register

Each working group must keep a list of all hazardous substances that are handled in the working group. Hazardous substances that are intermediate stages or reaction products intended for short-term testing do not have to be included in the list of hazardous substances.

The list must contain at least the following information:

The name to be used here is that which is listed in the operating instructions, in the labeling or in material information (e.g. safety data sheet).

In the case of preparations or products, the name of the preparation or product is sufficient if the dangerous ingredients or the dangerous substances that are produced or released can be seen from an available safety data sheet or comparable information and reference is made to this sheet.

If it is known that dangerous substances or preparations are produced or released when products are used as intended, these can be listed instead of the product without specifying the quantity. However, the classification or hazardous properties and the working area must be specified.

When specifying groups, hazardous substances of the same classification should be grouped together. The substances assigned to the group must be identifiable.

In the case of substances and preparations that require classification, the hazard designation and the associated risk phrase(s) must be given. It is sufficient to state the code letter of the hazard designation(s) (e.g. T, Xn, F) and the number of the R phrase (e.g. R 40/22) if the associated text can be found in a list.

In the case of substances and preparations that do not have to be classified, the hazardous ingredients that arise or can be released must be named with the hazard designation and the associated risk phrase(s).

In the case of hazardous substances that have not been placed on the market and that have been classified by the employer himself, the employer's self-classification must be stated.

The annual average amounts used or used are sufficient, whereby planned amounts can also be specified. Quantities are not required for substances that are not deliberately generated in the work area but have an effect on employees (diesel engine emissions, nitrosamines, sanitation).

If the hazardous substance is handled in a specific work area of a company, then the relevant area must be named. The determination of the hazardous substances used in a work area must be based on the intended handling.

The list of hazardous substances must be updated in the event of significant changes and checked at least once a year.

Therefore, the status (date of creation) and the date of the last inspection must be evident from the list of hazardous substances.

Significant changes can be:

  • New intake of hazardous substances
  • Change in product composition
  • change of classification
  • Change in volume ranges
  • Change in the work area in which the hazardous substance is handled as well as
  • Discontinuation of Use
