Bir metro inşaat projesindeki kaya düşmesi olaylarıyla ilişkili işçi yaralanmalarını azaltma çabalarında gerçekçi bir hedef, kaya düşmesi tehlikesi yaratan koşulları değerlendirmektir. İşverenler bu riskleri doğru bir şekilde değerlendirebilmesi ve uygun teknik ve idari kontrolleri uygulayabilmesi durumunda, riskleri daha iyi hafifletebilirler. Bu hedefi başarmak için Kök Neden Analizi (RCA) metodolojisi, risk değerlendirmesi yöntemi olarak düşünülebilir. Etkili bir risk değerlendirme yöntemi, değişken tavan koşullarını gözlemleme ve bunların işçileri ne kadar potansiyel olarak yaralayabileceğini değerlendirme yeteneğini içermelidir. RCA'nın değişen koşullarla ilişkili riskleri önceliklendirme yeteneği, tavanı istikrarlı hale getiren veya malzemenin tavanından düşme riskini azaltan kontrolleri tasarlama, onaylama veya kurma sorumluluğu olan herkes için önemli faydalar sağlar. Bu çalışma, bir metro inşaat projesindeki kaya düşmesi olaylarının risklerini ve nedenlerini RCA metodolojisi kullanarak bir vak'a analizi üzerinden incelemektedir. Bu çalışma, tavanın düşmesi gibi sistem düzeyindeki başarısızlıkları ve zayıflıkları geliştirmeye yardımcı olabilecek bir RCA metodolojisinin kullanımını açıklamaktadır. Ayrıca, mevcut raporlar, kazalara yol açan nedenler inceledi ve balık kılçığı yaklaşımını kullanarak bütün faktörler değerlendirildi. Buna göre, yetersiz eğitim, deneyimsizlik ve uygun olmayan ekipman kullanımı kazaların nedenleri olarak belirlendi. İhmalci davranışlar, güvenlik prosedürlerini izlemede başarısızlıkla birlikte, tehlike kaynaklarından biri olarak belirlendi.

REDUCING ROCKFALL HAZARDS IN SABIHA GOKÇEN – TAVSANTEPE METRO PROJECT CONSTRUCTION BY USING ROOT CAUSE ANALYSIS METHODOLOGY

Öz

A realistic goal in efforts to reduce worker injuries related to rockfall incidents is to assess the conditions that create a rockfall hazard. If employers can properly assess the risks of rockfall and implement appropriate technical and administrative controls, they can better mitigate the risks. In order to achieve this goal, the methodology of Root Cause Analysis (RCA) can be considered as a method of risk assessment. An effective risk assessment method should include the ability to observe variable ceiling conditions and assess how much potential they represent for injuring workers. RCA's ability to prioritize the risks associated with changing conditions provides significant benefits to anyone responsible for designing, approving, or installing controls that are reasonably repeatable and stabilize the ceiling or reduce the risk of material falling from the roof. Herein, this study is based on a case analysis of the risks and causes of rock fall incidents in a metro construction project using the RCA methodology. This study explains the use of an RCA methodology that can help improve system-level failures and weaknesses, such as rocks falling from the ceiling of a tunnel. Furthermore, the present report examined the causes that led to the accidents and the predictors/variations were assessed using fishbone approach. Accordingly, inadequate training, lack of experience and the use of inappropriate equipment were identified as the causes of accidents. Careless behavior is also a major source of danger, in addition to failure to follow safety procedures.
