Risk Assessment

The procedure for a complete risk assessment is described in EN ISO 12100. In order to be able to present a risk assessment efficiently and, above all, completely, the sequence of steps plays an important role alongside the appropriate timing.

After defining the boundaries and the intended use of the machine, EN ISO 12100 is based on the tasks and activities that must be performed by persons on the machine. These activities are the basis for possible hazardous events, which are assigned to the normative hazards, such as crushing, shearing, cutting, etc., in the next step.

This approach has the advantage of focusing exclusively on relevant hazards. In addition, no hazards are forgotten.

In the subsequent risk assessment, the risk and the required risk reduction are determined using risk graphs (DIN EN ISO 13849-1, EN 62061).

For example, fixed and movable guards in accordance with EN ISO 14120 with and without guard locking and interlocking devices in accordance with EN ISO 14119 are used here.

Controller-based measures and safety functions are implemented in accordance with DIN EN ISO 13849-1, EN 62061, EN 60204-1 and EN 61800-5-2, for example.

Important: The leading standards are the C standards for each machine category. The risk-reducing measures have already been worked out in these standards and must always be taken into account.

The risk-reducing measures must be implemented in the following order:

1. Inherently safe design
2. Technical protective measures (guards, controller-based protective measures)
3. User information on residual risks

I would be pleased to create risk assessments for you, develop controller-based measures and safety functions and create verification documentation or expertises for your machines.

The risk assessment is created using a software tool that supports the procedure described above and provides clear documentation in various output formats.
