Accidents of Electrical and Mechanical Works for Public Sector Projects in Hong Kong

Abstract

A study on electrical and mechanical (E&M) works-related accidents for public sector projects provided the opportunity to gain a better understanding of the causes of accidents by analyzing the circumstances of all E&M works accidents. The research aims to examine accidents of E&M works which happened in public sector projects. A total of 421 E&M works-related accidents in the “Public Works Programme Construction Site Safety and Environmental Statistics” (PCSES) system were extracted for analysis. Two-step cluster analysis was conducted to classify the E&M accidents into different groups. The results identified three E&M accidents groups: (1) electricians with over 15 years of experience were prone to ‘fall of person from height’; (2) electricians with zero to five years of experience were prone to ‘slip, trip or fall on same level’; (3) air-conditioning workers with zero to five years of experience were prone to multiple types of accidents. Practical measures were recommended for each specific cluster group to avoid recurrence of similar accidents. The accident analysis would be vital for industry practitioners to enhance the safety performance of public sector projects. This study contributes to filling the knowledge gap of how and why E&M accidents occur and promulgating preventive measures for E&M accidents which have been under researched.

Implementation Phase Safety System for Minimising Construction Project Waste

“…This factor ranked sixth for minimising waste in time and fourth for minimising cost overrun. This result agrees with the findings of previous studies [12,72,73]. The importance of this factor lies in its containment: (1) preventing mistakes in supplies, (2) avoiding transport error and reducing supplier errors, (3) preventing mistakes in quantity surveys, (4) avoiding incorrect procedures of material delivery, (5) avoiding increase over the allocated quantities to purchase, (6) reducing the repetition of change orders and (7) reducing the waiting time for equipment replacement.…”

Classification of Economic Regions with Regards to Selected Factors Characterizing the Construction Industry

“…The tools that were used, and the results obtained using them, are a good starting point for the analysis of accidents in the construction industry around the world. A similar study can be found in [19], in which an analysis of accidents related to electrical and mechanical work was carried out. In these studies, a two-stage cluster analysis was used.…”

Optimalisasi Penerapan Keselamatan dan Kesehatan Kerja di Laboratorium

“…Instalasi listrik di semua laboratorium telah terpasang dengan baik, ini perlu diperhatikan karena pekerjaan kelistrikan dapat mengakibatkan kecelakaan serius dan komplikasi dengan risiko tinggi (Wong et al, 2018;Gille et al, 2018). Catu daya juga harus dijauhkan dari area basah dan instalasi harus mematuhi peraturan keselamatan listrik setempat (WHO, 2020).…”
