Application domain and functionalities

  • What is ChemRADE used for exactly?

    ChemRADE is a web-based application that allows you to manage all relevant aspects of risk assessment of hazardous substances in the workplace.

  • Does the Inspectorate SZW accept ChemRADE as a method for risk assessment and evaluation of hazardous substances?

    The Inspectorate SZW (I-SZW), the Dutch labour inspection, acknowledges a number of mathematical models that can be used in the risk assessment of hazardous substances including the European exposure assessment model ‘ECETOC Targeted Risk Assessment (TRA)’ (which is often used in the context of REACH), and the ‘Stoffenmanager’ exposure model. More information on this topic can be found on the I-SZW www.zelfinspectie.nl. The algorithms used in the ‘Stoffenmanager’ exposure model and the ‘ECETOC Targeted Risk Assessment (TRA)’ exposure model are both incorporated in ChemRADE.

  • Can ChemRADE be used in the context of REACH?

    Yes, ChemRADE is suitable for use in the context of the Use Compliance Check under REACH. By implementing the ‘ECETOC Targeted Risk Assessment (TRA)’ algorithm in ChemRADE, exposure scenarios from the annexes of the extended Safety Data Sheets can easily be simulated. This way, it can be determined whether the exposure level remains below the exposure limits when the hazardous substances is applied in different processes.

  • I already have a register of hazardous substances. Can this register be applied in ChemRADE?

    Yes, all available product and substance data can easily be imported into ChemRADE using the ChemRADE import format.

  • How are occupational exposure limits determined in ChemRADE?

    ChemRADE automatically determines an occupational exposure  limit (8h-tgg and 15min-tgg) for a substance based on available limits. This is done in analogy with the SER guidelines for deriving operating limits (in Dutch). If no threshold value has been entered into ChemRADE, limits are calculated tentatively on the basis of the COSHH Control Banding method. If desired, a limit for a mixture of substances can be documented in ChemRADE.

  • How are hazard classifications of products and substances determined in ChemRADE?

    The hazard classification (or Hazard Group) of a product or substance is determined automatically in ChemRADE based on the COSHH Control Banding method.

  • How is the CMR classification of products and substances determined in ChemRADE?

    The CMR classification (carcinogenicity, mutagenicity, reproduction toxicity) of a product or substance is automatically determined in ChemRADE based on the R and / or H-statements in accordance with the CLP regulation.

  • Are the occupational activities and workplaces defined in ChemRADE easily assigned to other products?

    Occupational activities and workplaces are defined once in ChemRADE. When carrying out a risk assessment, one need only to combine the respective activities and workplaces by means of a drop-down menu. A set of recorded activity-workplace combinations can then easily be transferred from one product to a selection of other products.

  • Can I prioritise risks using ChemRADE?

    No, ChemRADE evaluates the risk of exposure directly. Thanks to the efficient risk assessment method, the risk prioritisation stage can be omitted.

  • How are the exposure estimates in ChemRADE calculated?

    ChemRADE contains algorithms from the validated ‘Stoffenmanager exposure model‘ and ‘ECETOC Targeted Risk Assessment (TRA)’. The ChemRADE risk assessment is determined on the basis of these algorithms.

  • What does a ChemRADE risk assessment look like exactly?

    After selecting a product-activity workplace combination, an estimate of the air concentration during the activity is made for each component in the product. Additionally, a daily average concentration is calculated based on the given task duration and task frequency. Estimates are automatically checked against the 8h-TGG and 15min-TGG values of any of the components so it is immediately clear whether health risks are controlled or not.

  • I am obliged to assess risks without taking into account the use of personal protective equipment (PPE). Is this possible in ChemRADE?

    Yes. In addition to a regular risk assessment, ChemRADE automatically provides a risk assessment corrected for PPE.

  • What is the degree of reliability of exposure estimates produced by ChemRADE?

    ChemRADE applies the algorithms of the validated ‘Stoffenmanager exposure model‘ and ‘ECETOC Targeted Risk Assessment (TRA)’. The risk assessment calculated in ChemRADE is based on these algorithms.

  • Can I use ChemRADE to assess the risks of skin exposure?

    Yes, skin exposure is also quantified in ChemRADE and compared to available dermal Occupational Exposure Limits through the implementation of the ‘ECETOC Targeted Risk Assessment (TRA)’ algorithm.

  • What exporting options are incorporated into ChemRADE?

    The products and substances register, all exposure estimates and risk assessments and the plan of action can be exported easily in the form of MS Excel or PDF files. The information can be sorted and filtered as desired by the user.

  • What are ChemRADE’s system requirements?

    ChemRADE is a web-based application and can thus be used on any system with access to the Internet.

  • Is ChemRADE secure?

    Yes, the data in ChemRADE is stored in a highly secure and managed server. The transfer of information between server and web browser takes place through an encrypted SSL connection.

  • In what sectors is ChemRADE used?

    At the moment several companies in the following sectors use ChemRADE:
    – Petrochemistry (including multinationals in production of raw materials and bulk liquid storage terminals);
    – Chemistry (compilers of products for professional and consumer market, including glue and lubricant manufacturers, research laboratoria);
    – Food (including candy manufacturers and tobacco processors);
    – Pharma (synthesis and packaging of pharmaceuticals).
