Developing techniques for cause-responsibility analysis of occupational accidents.

Area of Science:

• Occupational Safety and Health
• Risk Management
• Construction Management

Background:

• Work-related accidents pose significant risks in the construction industry.
• Determining the root causes and responsible parties is crucial for effective accident prevention.
• Existing methods may not adequately detail responsibilities and their rates.

Purpose of the Study:

• To specify the causes of occupational accidents.
• To determine social responsibility and the role of involved groups in work-related accidents.
• To develop and test novel cause-responsibility analysis (CRA) techniques.

Main Methods:

• Development of occupational accidents causes tree and responsibility tree.
• Creation of an occupational accidents component-responsibility analysis worksheet.
• Application of developed cause-responsibility analysis (CRA) techniques, including occupational accidents tree analysis (OATA) and occupational accidents components analysis (OACA).
• Analysis of 100 fatal/disabling occupational accidents in Tehran's construction sector (2010-2014).

Main Results:

• The management group in construction projects bears a substantial 74.65% responsibility for work-related accidents.
• The developed OATA and OACA techniques effectively determine responsible groups and their rates of responsibility.
• The study identified specific tasks, responsibilities, and their associated rates contributing to accidents.

Conclusions:

• The developed CRA techniques are effective tools for occupational accident investigation and analysis.
• Pinpointing management's high responsibility rate provides a clear focus for accident prevention strategies.
• Implementing these techniques can lead to targeted interventions and reduced work-related accidents.
