It has been pointed out that the act of carrying a heavy object that exceeds a certain weight by a worker at a construction site is a major factor that puts physical burden on the worker’s musculoskeletal system. However, due to the nature of the construction site, where there are a large number of workers simultaneously working in an irregular space, it is difficult to figure out the weight of the object carried by the worker in real time or keep track of the worker who carries the excess weight. This paper proposes a prototype system to track the weight of heavy objects carried by construction workers by developing smart safety shoes with FSR (Force Sensitive Resistor) sensors. The system consists of smart safety shoes with sensors attached, a mobile device for collecting initial sensing data, and a web-based server computer for storing, preprocessing and analyzing such data. The effectiveness and accuracy of the weight tracking system was verified through the experiments where a weight was lifted by each experimenter from +0 kg to +20 kg in 5 kg increments. The results of the experiment were analyzed by a newly developed machine learning based model, which adopts effective classification algorithms such as decision tree, random forest, gradient boosting algorithm (GBM), and light GBM. The average accuracy classifying the weight by each classification algorithm showed similar, but high accuracy in the following order: random forest (90.9%), light GBM (90.5%), decision tree (90.3%), and GBM (89%). Overall, the proposed weight tracking system has a significant 90.2% average accuracy in classifying how much weight each experimenter carries.

<p>In recent years in building construction site construction workers due to the complexity, the project construction period, the working environment is poor, the construction process hazard and more security-conscious workers partial bottom. When accidents occur, such as by falling, falling objects wounding, electric shock, earthmoving collapse, overturning and other machinery, causing casualties, to construction companies and property losses caused by the economy to varying degrees. Throughout its reasons, one is security responsibilities are not clear, safety supervision and management system is not perfect, the other is the weakening of the internal management of construction enterprises, especially flawed construction site management, lack of effective security measures, the responsibility is not implemented, management personnel and operations personnel have not performed the necessary education and training, lack of knowledge of security technologies, illegal command, illegal operation.</p>

Abstract Safety management is very important for construction sector as it is the most hazardous working environments when it comes to occupational fatalities. The high cases such as injuries at the workplace, illnesses, and fatalities often caused harm to the workers and create the delay on the work progress. Therefore, this paper reviewed the whole operation process of the sensor modules that enhanced safety performance to prevent accidents occurred on construction site. By providing lab scale location-based safety management services to the workers, this technology able to allow a speedy response in the event of accident. From the benchmark conducted, there are three study that had been conducted previously using vibrational alert signal which identified as an accurate transmitted especially inside a danger zone, as the vibrational function of the sensor module able to function within the designated range. The second benchmark shows that previous study able to identify errors in the location information of the workers arising from obstacles, even though so the technology able to conveyed within the designated range as well. Thirdly, the previous study able to shows the information of a fall was conveyed quickly upon occurrence, and the previous study showed that fall able to identified using the context-aware information from the sensor module. The findings showed that the real-time location and context-aware information collected from the sensor module can be used to prevent accidents and respond quickly in the event of a fall. However, the vibration signal which generated by sensor module was insufficient to alert the workers when approaching the danger zone at construction site. Therefore to improve the whole development of prototype sensor module a further study is needed to incorporate the vibrational and alarm signal for recognising accidents upon occurred for enhancement safety management at construction sites.

Abstract BackgroundPersonal Protective Equipment (PPE) is a material, device, equipment or clothing which is used or worn by a worker to protect them from exposure or contact with any harmful material or energy which may cause injury, disease or even death. The use of personal protective equipment is a universal legal requirement to protect workers against occupational injuries and illnesses in their workplace. The international labor office estimates that every year there are some 125 million work-related accidents, 220, 000 of them are fatal. This study assessed personal protective equipment utilization and associated factors among building construction workers in Addis Ababa, Ethiopia 2019.MethodsInstitution based cross-sectional survey was conducted on the selected construction sites in April 2019. Data was collected by using pre-tested Amharic questioner from 206 study subjects with a response rate of 100% via face to face interviews. Epi info version 7.1 and SPSS version 25 were used for data cleaning and analysis respectively. Independent variables with P<0.2 were transformed from bivariate to multivariate logistic regression. P<0.05 and was declared as an associated factor.ResultsThis study showed that (38.3%) of construction site workers were used at least one personal protective equipment. Presence of safety training, safety brief before commencing work and the availability of governmental visits were associated factors for utilization of personal protective equipment. Regarding, the type of injuries that occur on a majority of workers were abrasion (35%) and climbing at high was the common cause of injury. ConclusionsPPE utilization and safety measure in construction industries is insignificant and construction site workers are not adapted to take care of themselves as it manifested by low use of PPE. An effort for occupational safety assurance should be put in practice to avoid accidents on building a site with an unconditional commitment to all the projects. Riddance of hazards and deterrence of accidents on-site should be within the proficiency of each site. The client should be involved in safety management coupled with having a great craving for safety.
