Early intervention mechanism for preventing electrocution in construction engineering

Area of Science:

• Construction Engineering
• Occupational Safety and Health
• Risk Management

Background:

• Electrocution remains a significant hazard in the construction industry, leading to preventable fatalities.
• Existing safety measures may not adequately address the complex interplay of factors contributing to electrical accidents.

Purpose of the Study:

• To develop an effective early intervention mechanism for construction engineering to prevent electrocution incidents.
• To improve labor safety and reduce the risk of casualties in the construction sector.

Main Methods:

• Utilized narrative text analysis and the Haddon Matrix for data collection.
• Employed the exhaustive chi-square automatic interaction detector algorithm to analyze correlations among 113 electrocution deaths.
• Designed the early intervention mechanism using IDEF0 (Integrated DEFinition for Function Modeling) based on the Theory of Inventive Problem Solving (TRIZ).

Main Results:

• Identified key hazard correlations between operating features and conductive media, pinpointing entry points for electrocution prevention.
• Proposed the establishment of inspection stations for electric tools to ensure the safety of portable power equipment.
• Successfully integrated TRIZ and IDEF0 to create a robust pre-entry testing and safety mechanism framework.

Conclusions:

• The developed early intervention mechanism effectively addresses operating features linked to electric shock hazards.
• The study provides a novel approach to risk reduction through systematic hazard analysis and targeted safety interventions.
• Recommendations include implementing tool inspection stations and pre-entry testing to strengthen overall construction site safety.
