The article presents a case study of the identification and analysis of operating and equipment losses in a steel plant. Losses may be visible in costs resulting from premature wear of machine and equipment components, removal of emergency failures related to quality losses, including loss of reputation of a reliable supplier, as well as losses related to production, especially in the case of continuous production. The analysis of losses was based on the cost criterion, including losses resulting from the loss of a potential client. The real data from the 2016 were used in the case study. In order to ensure proper operation at the finishing department, standard solutions have been developed. The analysis of losses was based on the Pareto principle and the analysis of TPM coefficients.


In this paper TPM and PAMCO coefficients were shortly characterised. On the basis of TPM coefficients its effectiveness was estimated. Thanks to using time and PAMCO coefficients, the utilization of working time machines was researched. Moreover, there a correlation between TPM coefficient and the quality level was examined. A histogram was drawn up in order to illustrate the distribution. The obtained results allowed to evaluate the effectiveness of the machine. The period of research embraced fifty-two weeks (1 year) and the object of the analysis is the injection moulding machine.

Lean Management is currently one of the best-known and is the most widely used management concepts in production enterprises. Lean creates such a culture of work in an organization that makes all participants in the organization interested in raising the level of quality, reducing costs and delivery time. However, there is no information about the influence of lean tools on the level of safety in production organizations. The paper presents the influence of five lean tools on the safety level by the example of metal manufacturing organization. The number of potentially dangerous situations and the number of accidents were taken as the measure of safety level. The obtained results indicates that the most important for the safety level is 5S, TPM while Kaizen, Poka-Yoka and VSM are smaller. The paper aims to broaden the knowledge about the dependence of the use of lean tools on the level of occupational safety.


The presence of dioxin-like compounds, such as chlorinated dibenzodioxins, chlorinated dibenzofurans and chlorinated biphenyls, in mainstream cigarette smoke has been investigated for seven cigarette brands covering a range of ‘tar’ deliveries from 1 mg to 14 mg. Adjusted per milligram of total particulate matter (TPM), ultra-light cigarettes had the highest concentrations of toxic equivalents (TEQ) of 10 fg/mg TPM. As the ‘tar’ delivery increased, lower concentration values were found in lights and full-flavor cigarettes. Calculated on the basis of a pack of twenty cigarettes, mainstream smoke from the ultra-lights and lights products produced values around 200 fg TEQ, and the full-flavor brand produced 575 fg TEQ per pack. Levels of TEQ from dioxin-like compounds in the tobacco section of four cigarette brands did not show significant differences and were similar to previous literature findings.
