Evaluation of Noise Level at the Position of Water Cutter Operator at Selected Enterprise

Pałęga Michał, Kwapisz Marcin

New Trends in Production Engineering

2019

Vol. 2, Iss. 2

341-349

The subject of this publication is to assess the exposure of the water jet operator to the noise hazard. The publication presents basic information about noise in the work environment. Next, the procedure of noise measurement in the work environment was discussed and the results of tests carried out at the water jet operator's station for three basic activities were presented, ie: (1) plotter support, supervision of the cutting process, loading and receiving material, (2) auxiliary, transport and cleaning, (3) computer service, keeping documentation, hygienic and social break. The noise level test included the determination of: the maximum sound level A LAmax the peak sound level C LCpeak, the noise exposure level related to the 8-hour work day LEX,8h. Based on the obtained measurement results, it can be stated that the exposure to noise at the station of the waterjet operator is at an acceptable level.

The subject of this publication is to analyze the circumstances and causes of accidents at work in a selected industrial enterprise that provides services in the field of water jet cutting and laser beam. The paper present the statutory definition of an accident at work and its basic categories (light, heavy, mortal and collective accident). It also discusses the most popular accident investigation method – the TOL method, which classifies the causes of accidents into three basic groups: material-technical, organizational and human. In the further part of the work the characteristics of the waterjet operator's work station were made, including the scope of activities, possible occupational hazards and preventive actions. Next, the results of the analysis of the circumstances and causes of accidents at work were presented. In the period from 2013 to 2018 eight accidents were reported, resulting in minor injuries, such as cuts and cuts, fracture of the phalanx, overloading of the spine, leg twisting or knee injury.
