To enable a simple research to the subjects addressed in the standard occupational health and safety hazards ' content hazards treated in classes were divided into standards . The notations of the classes were formed from sequences of letters . After the specific types of hazards and strains ( eg, chemical hazards ' electrical hazards ' mechanical hazards ' etc.) can be searched directly in the overview list by clicking the desired class.

The classes are in turn divided into sub-classes (eg mechanical hazards - Class D - in subclasses such as DB " squeezing, pinching " or DF " fall, slip, trip ' fall '" etc. ) . If standards were available, the contents of which were not allocated to one subclass ' the first sub- class has the name of the upper class with the words " in general" and recognized those standards . In order to cover standards that make only indirect statements about hazards that class A was compiled . This includes standards with terminological definitions ' measurement and testing procedures ' and standards that deal with the consequences of hazards.

The number of existing standards to the upper and lower classes is displayed in the overview list of classes ( index list). A hit list of the standards found can be retrieved. From this out further information ( eg, short summaries of the individual standards) can be displayed.

A combination with other search criteria is only possible via the advanced search.

The index contains the entire field entry.
