The obligation to report serious accidents applies only for salaried employees or self-employed if they work under the authority of others. If someone is self-employed and working under his own authority when an accident happens, the accident is not reportable.

The used accident data is taken from the accident database of the Dutch Labour Inspectorate. This database contains investigated reportable accidents.

The manual of webORCA explains the use and possibilities of webORCA via screenshots. Using a simple example, the main steps necessary to calculate a risk are carried out. In addition, assumptions and definitions are explained.

WebORCA is the Web version of ORCA (Occupational Risk Calculator). Based on the input of actual working conditions and duration of exposure to hazards, the model calculates the risk for various activities in the workplace or for different occupations.
