Since the last decades, wood splitters have considerably facilitated the production of firewood. However, the risk for severe injuries has come along with this technique. The aim of the present study was to analyze wood splitter-related accidents to be able to identify potential risk factors when producing firewood. Based on these results, existing measures for preventing accidents should be revised. In total, 140 moderately severe, severe and lethal wood splitter accidents and 23 scores of user questioning were analyzed with chi-square test. The majority of the injured men ranged in age from 40 to 80. Three quarters of all accidents (72,6 %) happened during usual movement sequences of the splitters. Two thirds (65,3 %) were reduced to disregarding instructions, carelessness and nonattention. The contracted injuries were halfway amputations (2005 – 2007: 53,3 %; 2008: 50,0 %) and partial amputations. The reasons why and how exactly the accident victims got hurt, could not be identified during the data analysis. By interviewing accident victims was found that those who were not working in agricultural jobs tend (10/12; 83,3 %) to collaborate with an assistant. People that work with an assistant stated faster and safer progress in work (10/13; 77 %). The most common accident cause was hurting at the wood splitter itself while mounting the wood pieces (8/23; 35 %), accidents during assembling and servicing wood splitters (5/23; 22 %) and bypassing safety devices, grabbing firewood and tweaking between already splitted firewood (each time 3/23; 13 %). The evaluation of novel wood splitters has shown that they conform to the European standard (EN 609-1) and machine norm (2006/42/EG). Nevertheless, these standards could be reviewed for further optimizing wood splitters, as accidents still happen. Possible new technologies for improving these products could be techniques based on laser, thermal imaging camera, RFID (Radio Frequency Identification), and videosensor. Producers of novel wood splitters could be provided with information on preventing accidents. Further research like interviews with manufacturers, a motion analysis and a body of experts for discussing these research results and prevention measures is recommended.
