Accident risks and the effect of performance feedback with industrial CO2 lasers

Abstract A safety survey of seven industrial CO 2 lasers was carried out in order to discover the hazards, the incidents which have occurred, and perceived safety risks. A safety behaviour modification programme was developed and implemented in one laser workshop. Beam related incidents were not as rare as was expected on the basis of earlier analyses and reported accidents. Most incidents, however, related to the materials handling in the workstation. The performance feedback improved safety behaviour effectively. The baseline safety level was 50%, and during the feedback it rose up to 90%, while two months after the feedback it was 72%.
