Identification of hazards and risk assessment for the workplace of maintenance worker of a bucket-wheel excavator - case study

Abstract

The subject of this paper is the identification of hazards for the workplace of the maintenance worker bucket-wheel excavator SRs 1200x24/4, as well as the risk assessment for that workplace. In addition to the hazards arising from the design of the machine itself, ergonomic hazards have been identified, as well as hazards arising from the working environment. The HRN (Hazard Rating Number) method was used to assess the risk. The emphasis of the paper is on the comparison of the original HRN method with two modifications of this method. The mentioned modifications refer to the tabular values of the influencing factors used in the risk assessment. It was concluded that the original HRN method still represents a solid basis that allows its application in practice for risk assessment.
