Performing a risk assessment

Performing a risk assessment according to EN ISO 12100

The risk assessment process according to EN ISO 12100 consists of several steps that ensure all potential hazards are thoroughly investigated and evaluated. These steps are:

  1. Determining the limits of the machine
    The first step is to define the operational limits of the machine. This includes determining the intended use, operating conditions, foreseeable misuse, and the machine's lifetime.

  2. Identifying hazards
    Next, all hazards that may arise during the machine's lifecycle are identified. These include mechanical, electrical, thermal, and other hazards that may cause injury or damage.

  3. Risk assessment
    The risk of each identified hazard is then assessed. The risk assessment is based on the severity of potential injuries or damage and the likelihood of such an event occurring. This can be a qualitative or quantitative evaluation.

  4. Risk evaluation
    The risk is then compared to the established acceptance criteria. If the risk is deemed unacceptable, additional measures are required to reduce the risk.

  5. Risk reduction
    In the risk reduction step, the risk is reduced by implementing technical, organizational, or personal protective measures. The principle of the three stages of risk reduction applies here:

    • Inherently safe design: Reducing the risk by designing the machine or process.

    • Protective measures and safety devices: Implementing safety devices such as guards, emergency stops, or light curtains.

    • User information: Providing warnings, instructions, and training.

  6. Verifying the risk reduction
    After implementing measures, it is verified whether the risks have been reduced to an acceptable level. If necessary, additional measures are taken or existing measures are adapted.

  7. Documenting the risk assessment
    All steps of the risk assessment, the identified hazards, the measures taken, and the results of the verification must be documented. This documentation is an important proof of compliance with legal requirements and serves as a reference for future assessments.

By consistently applying the CE-CON Safety Tool, this process can be efficiently implemented and compliance with EN ISO 12100 ensured.
