Chemical safety report
CSR , including CSR ( English chemical safety report ) is a term from the hazardous substances.
Documenting the chemical safety assessment is called so ( English chemical safety assessment ) that after the REACH regulation is required for all substances subject to registration in quantities of more than 1 tonne per year per registrant. The chemical safety assessment includes assessments of the harmful effects on health and the environment , persistence and bioaccumulation . In the case of dangerous or particularly worrying substances, acc. Art. 14 para. 4 REACH also carry out an exposure assessment (with the creation of exposure scenarios ) and a risk description. The information in the safety data sheet must in accordance with Art. 31 para. 2 REACH must be compared with the chemical safety assessment.
The REACH regulation is based on the principle that the industry must ensure that the substances manufactured or imported are not dangerous to human health or the environment. The chemical safety report is used to ensure for all risks how these risks can be reduced to a minimum or even avoided entirely.
The document also serves as an information source, along the supply chain is passed (supply chain). The manufacturers / suppliers are obliged to release the assessment of the respective substances to the downstream users.
The components of a chemical safety report
The document consists of three parts:
- Determination of adverse effects
- Exposure assessment
- Risk description
Determination of adverse effects
In order to conduct a successful investigation, one must collect and evaluate all relevant information about the substance . Such information is e.g. B. the properties of the substance , information about the manufacture and use, the exposure limit etc. If the information according to REACH regulation is insufficient, additional information must be obtained.
The aim is to identify the harmful effects of the substance , to assess their effects and what impact they have on human health and the environment. The substance must meet one of the following criteria:
- Must be considered dangerous
- Is a PBT / vPvB substance
If the determination reveals that the substance is not considered hazardous and not a PBT - / - vPvB substance, the safety assessment ends at this point.
Exposure assessment
The exposure assessment is the process of measuring or estimating the dose of the substance , which is or can be exposed to humans and the environment, depending on the uses of the substance. The information about the manufacturing conditions and uses is called an exposure scenario. The limit values for humans and the environment must be determined for each exposure scenario. All uses are listed in the exposure scenario and the life cycle stages of the substance are precisely described.
Risk description
When describing the risk, the respective exposure levels are compared with the threshold values. If a threshold cannot be assigned, a quantitative or semi-quantitative approach is used. The risks are considered “controlled” when the exposure limit is within the threshold values that are safe for both humans and the environment. If there is no threshold, exposure must be minimized as much as possible so that the risk is considered to be under control according to the REACH regulation .
If the risks cannot be controlled, the safety assessment must be refined. Possibilities are:
- Collection of other relevant data
- Change of manufacture or use
The conditions that ensure the control of the risks form the so-called final exposure scenario. The safety assessment is documented in the Chemical Safety Report (CSR). The exposure scenarios are passed on through the supply chain as part of the E-SDS .
If the risks cannot be controlled despite further refinements, use is not recommended and is documented in the E-SDS .
