A Method For Determination of Accident Probability in Construction Industry

Abstract

Safety issues within the construction industry have been an area of concern in almost every country. In this paper, an objective and quantitative accident probability calculation approach is proposed using 623 actual construction accidents that resulted in 681 casualties between the years 2000 and 2013. Of these accidents, the first five account for 84.1% of all fatalities and 85.4% of all injuries. In total, five construction jobs (excavation, reinforced concrete work, masonry, plastering and painting, and roof work) were the focus of the study, as they account for 70.8% of all occurrences. Probability values were calculated by using the Poisson distribution, in which accident rates and exposure values were used as distribution parameters. In an industry where accidents are recorded according to non-specific standards, it is very difficult to represent the probability of accidents within a known distribution model. The proposed approach in this paper provides an objective method to obtain probabilities by using the Poisson distribution for construction accidents.

Identifying Factors that Contribute to Severity of Construction Injuries using Logistic Regression Model

“…Research efforts in occupational safety and health field have mainly concentrated on determining the causes of occupational injuries and illnesses and thus help discover new strategies to reduce or eliminate them. Majority of research studies in the past used surveys to collect information from employers and workers [1][2][3], while several studies preferred to use descriptive statistics to summarize and interpret occupational injury and illness data [4][5][6][7][8][9][10][11][12]. Even though conducting surveys and using descriptive statistics may be helpful, such as describing how the accident occurred and who were involved; using them alone is not sufficient in determining the factors that contribute most to the unfortunate incident.…”

Safety net applications in developing countries: Turkey and Iran case study

“…This affects safety culture and climate especially in small and medium sized enterprises. High fatal accident rates in developing countries indicate that the OHS culture has not yet been fully adopted [7]. Altough legislation enacted in recent years, obligation of OHS training at undergraduate level and tightening of the inspections have positive effect on the occupational accident statistics in the construction sector, it has not reached a sufficient level yet compared to developed countries [7,8].…”

“…In the construction sector, the first reason of the work accidents is "falling from the height" [7,[9][10][11][12][13]. Accidents caused by falling from height are followed by struck by thrown and projected or falling object accidents [7,8,14,15]. The accident types of falling from height are; falls from scaffold; falls from floor slab or platform edges; falls from floor and elevator openings and falls from roofs and other falls [8].…”

“…The accident types of falling from height are; falls from scaffold; falls from floor slab or platform edges; falls from floor and elevator openings and falls from roofs and other falls [8]. Accidents caused by falling from buildings may effected by many reasons such as building height, wind speed, employees' attitudes and risky activities [16,17] and it is determined as the most dangerous accident type [7,17]. 47.5% of the occupational accidents occurred in the Turkish construction sector are due to worker or material fall [10].…”

İşçi̇ Sağliği Ve İş Güvenli̇ği̇ (İsi̇g) Si̇stemi̇ni̇n İnşaat Uygulama İş Programina Entegrasyonu

“…İnşaat sektörünün gelişmekte olan ülkelerde ekonomi ve sosyal politikalar üzerinde çok büyük bir pozitif etkisi bulunmaktadır. Bu olumlu etkilerine rağmen en büyük zarar da yine aynı sektörde meydana gelen ölümlü iş kazalarından kaynaklanmaktadır [3]. Bu kazaların olmasının nedeni; sektörün kendine has yapısı, alt yüklenicilerin ve ana yüklenicilerin koordinasyonunda yaşanan zorluklar, tek bir alanda birden fazla farklı iş kolunun birarada çalışmasının zorunluluğu, eğitimsiz iş gücü ve projenin kendi yapısından kaynaklanan riskler ve tüm bunlarla birleşen insan yaşamını göz ardı eden, iş güvenliğini arka sıralara iten bakış açısıdır [4].…”
