Reduction of Occupational Accidents with The Six-Sigma Method And Application in The Textile Industry

Abstract

In this study, the number and types of occupational accidents in the Indigo section of a denim fabric production factory where Six Sigma DMAIC method is applied are analysed. In the Indigo department, 136 occupational accidents occurred between 2018 and 2023. It is seen that 650 lost working days were experienced as a result of occupational accidents. The part of this data between 2018-2020 represents the part of the six sigma study that has not been implemented, and the part between 2021-2023 represents the part where the six σ study has been implemented. The number of accidents decreased from 84 to 52 and the number of lost working days decreased from 379 to 271 days. Thus, it is seen that there is an improvement of 38.09% in the number of occupational accidents and 28.5% in the number of lost working days. OAFR decreased from 12.1 to 11.7 and improved by 3.3%. OASR has decreased from 124 to 98 and an improvement of 27.1% has been realised. The sigma level of the process increased from 4.71σ to 4.87σ. Lost working hours, the amount of errors per million opportunities, decreased from 655 to 371. This is an improvement of more than 18,5 per cent in lost working hours.

Altı Sigma Yöntemi ile İş Kazalarının Azaltılması ve Tekstil Sektöründe Bir Uygulama

Öz

Bu çalışmada, Altı Sigma TÖAİK (Tanımlama, Ölçme, Analiz, İyileştirme, Kontrol) yönteminin uygulandığı bir denim kumaş üretim fabrikasının İndigo bölümündeki iş kazalarının sayısı ve türleri analiz edilmiştir. İndigo bölümünde 2018-2023 yılları arasında 136 iş kazası meydana gelmiştir. İş kazaları sonucunda 650 kayıp iş günü yaşandığı görülmektedir. Bu verilerin 2108-2020 yılları arasındaki kısmı six sigma çalışmasının uygulanmadığı kısmı, 2021-2023 yılları arasındaki kısmı ise six sigma çalışmasının uygulandığı kısmı temsil etmektedir. Kaza sayısı 84'ten 52'ye, kayıp iş günü sayısı ise 379 günden 271 güne düşmüştür. Böylece iş kazası sayısında %38,09, kayıp iş günü sayısında ise %28,5'lik bir iyileşme olduğu görülmektedir. İş kazası sıklık hızı (İKSH) 12.1'den 11.7'ye düşmüş ve %3.3 oranında iyileşmiştir. İş kazası ağırlık hızı (İKAH) 124'ten 98'e düşmüş ve %27,1'lik bir iyileşme gerçekleşmiştir. Sürecin sigma seviyesi 4.71σ'den 4.87σ'ye yükselmiştir. Bir milyon fırsat başına düşen hata miktarı olan kayıp çalışma saati 379'dan 271'e düşmüştür. Bu, kayıp çalışma saatlerinde yüzde 18,5'ten fazla bir iyileşme anlamına gelmektedir.
