The aims of this project has been to analyse the work environment of earth moving machinery operators and suggest improvements. Interviews with operators and contractors; assessments of personal injury risks and costs to the companies and suggestions for improvements based on literature, statistics and interviews have been carried out. The results show that the work environment is strenuous. Overexertion injuries and falling are the most common injuries. The cost of injuries at one company was estimated at approximately 1/3 of the company profit. Risk reducing measures are suggested and discussed. For the analysed company the costs are reduced from 1/3 to 1/8 of the company profit after pay-off time of investments. It is concluded that the operators have a strenuous work environment and that the injuries are expensive, but possible to reduce.
