Based on data from the Dutch accident surveillance system PORS, other Dutch and foreign accident sources, it was attempted to establish the fact ors relating to the occurrence of do-it-yourself accidents.

It is recommended that the current preventive activities should be continued, yet an increase of the activities does not seem necessary. S ome specific fields for future attention are indicated: accidents involving do-it-yourself tools (especially hand-operated ones, like stanley knives), vehicles, cutting or piercing objects, and accidents leading to eye or han d injuries.
