The use of quality management tools to ensure safe working conditions at CO2 laser workstations

Ciecińska Barbara, Oleksiak Beata

Dynamic development of various technologies replacing existing, difficult or in various ways arduous, is the reason for replacing equipment with modern ones. New equipment may be associated with a different power supply, a different way that the construction materials are processed or the tools used, than the previous one. Then arises a need to re-examine whether the working conditions at a workplace are safe, what onerous and hazardous factors are associated with the work. An example of such a technological change could be a laser processing, when equipment using a concentrated energy stream, properly controlled, produces a specific effect on materials. However, along with the benefits of the new technology, come also many risks, such as the effects of radiation on matter and the human body, electricity, fire hazards, the problem of toxic emissions and others. This paper presents the problem of ensuring work safety at a newly commissioned CO2 laser station. Technique of brainstorming was used to identify and analyze the working conditions and types of hazards. These may be different from what was previously known, partially known, or even unconscious. Ishikawa diagram was developed and shown to be an effective tool for detailing and structuring problems in relation to safety. In the case of a technical problem, a poka-yoke solution to eliminate the hazard was proposed. Problems occurring at the workstation during machining and related to its operation were assigned, using the affinity diagram, to specific departments of the company, according to its work organization, which can significantly facilitate the management of the work and employees of the different departments in the future, in order to ensure safe and hygienic working conditions.
