Factors influencing the implementation of a safety management system for construction sites

The objective of the study was to determine the influential safety factors that governed the success of a safety management system for construction sites. The number of incidences among construction workers and the level of awareness on matters concerning safety were also determined. The study involved a self-administered three-part questionnaire among the workers and interviews with industry experts involved in brick-laying, concreting and in related assorted trades. Part A of the questionnaire concerned personal particulars, Part B involved training and experience and Part C was based on 28 industry-accepted safety factor elements. The construction sites ranged from high rise buildings, landed houses and infrastructure renovation. The sample size was 275. From the survey it was found that the most influential safety factor was personal awareness followed closely by communication. Suggestions and recommendations on equipment design and improved work practices and procedures to improve the efficiency and productivity of construction workers were proposed. Management was urged to get their workers better informed about safety matters.

CSHM: Web-based safety and health monitoring system for construction management

INTRODUCTION: This paper describes a web-based system for monitoring and assessing construction safety and health performance, entitled the Construction Safety and Health Monitoring (CSHM) system. METHOD: The design and development of CSHM is an integration of internet and database systems, with the intent to create a total automated safety and health management tool. A list of safety and health performance parameters was devised for the management of safety and health in construction. A conceptual framework of the four key components of CSHM is presented: (a) Web-based Interface (templates); (b) Knowledge Base; (c) Output Data; and (d) Benchmark Group. RESULTS: The combined effect of these components results in a system that enables speedy performance assessment of safety and health activities on construction sites. With the CSHM's built-in functions, important management decisions can theoretically be made and corrective actions can be taken before potential hazards turn into fatal or injurious occupational accidents. IMPACT ON INDUSTRY: As such, the CSHM system will accelerate the monitoring and assessing of performance safety and health management tasks.

Safety line method for the prediction of deep coal-seam gas pressure and its application in coal mines

Gas pressure is an important index for evaluating the outburst risk and determining the gas content in coal seams. It is recommended to predict coal-seam gas pressure of the workface at deep levels before extending mining activities to deeper levels. According to the prediction results, measurements are taken for gas outburst prevention and control and for workload estimation. At present, regression methods are always used to process the numerous gas pressure data for prediction. Because there are many factors that influence the gas pressure which could lead to a deviation from actual values, the measured data do not possess basic conditions for regression methods; this can cause unexpected dangers if the methods are adopted.Based on a statistical analysis of actual measured results of coal-seam gas pressure in a same geological section in certain coal mine, two symbol measured points are selected to make a line for prediction, i.e. safety line, and the other measured points should be below the line except the abnormal points due to the confined water. It has been successfully applied in numerous coal mines in China. Particularly, this method is analyzed in this paper for the case of the No. 8₂ coal seam in the Taoyuan coal mine in Huaibei coalfield, China. By comparatively analyzing the relationship between gas pressure and depth from surface using regression methods, it is found that the safety line method could lead to a better prediction for deep coal-seam gas pressure, and therefore promote early warning ability and mining safety.
