Risk-based Analysis of Construction Accidents in Iran During 2007-2011-Meta Analyze Study

Area of Science:

• Occupational Health
• Construction Safety
• Accident Analysis

Background:

• Construction industry poses significant occupational risks.
• Understanding accident characteristics is crucial for worker safety.
• Previous studies lack comprehensive analysis of Iranian construction accidents.

Purpose of the Study:

• To investigate occupational accident characteristics in the Iranian construction sector.
• To analyze the frequency and severity of work-related accidents among insured workers (2007-2011).
• To identify high-risk groups and contributing factors to accidents.

Main Methods:

• Utilized the Iranian Social Security Organization (ISSO) accident database (21,864 cases, 2007-2011).
• Calculated Total Accident Rate (TAR), Total Severity Index (TSI), and Risk Factor (RF).
• Analyzed data based on worker demographics, occupation, construction phase, work schedule, location, accident type, and body part affected.

Main Results:

• Young workers (15-19) showed a TAR of 13.4%, nearly six times the average (2.51%).
• Laborers and structural workers (TAR=66.6%) and those working at heights (TAR=47.2%) had higher accident rates.
• Older workers (>65), work supervisors, and night shift workers experienced more severe accidents (higher TSI).

Conclusions:

• Young, laborer, and night shift workers require enhanced workplace supervision.
• Mandatory use of Personal Protective Equipment (PPE) is essential, particularly for outdoor and at-height work.
• Policymakers should prioritize safety improvements in less developed and colder western regions.
