“…Research on FFH prevention and monitoring has been conducted by Zhang et al [15], who developed an automated rule-checking framework that integrates safety into BIM and allows preventive detection of fall-related hazards to prevent falls, near-misses, and accidents. Tanvi et al [2] identified technologies that ensured safety at heights and their application in the construction industry. The authors provided an in-depth understanding of how technology can prevent fall accidents.…”

“…Different practices, such as work-at-level (WaH) principles and other rules, have been created to oversee FFH incidents. However, such injuries are still occurring, highlighting the potential lack of implementation or negligence of such systems on construction sites [2]. According to Construction Fatality Assessment and Control Evaluation (FACE) database [3], between 1982 and 2015, 42% of deaths in the construction industry were related to falls.…”

“…For instance, according to Occupational Safety and Health Administration (OSHA), all workers working at a height above two meters are prone to falls and must use PPE [12]. Regrettably, despite the legal stipulations in the national laws and international standards, workers rarely use PPE at heights mainly because of low safety awareness or discomfort while wearing the safety gear [2]. This trend is more pronounced in developing countries.…”

Falls from height (FFH) are common safety hazards on construction sites causing monetary and human loss. Accordingly, ensuring safety at heights is a prerequisite for implementing a strong safety culture in the construction industry. However, despite multiple safety management systems, FFH are still rising, indicating that compliance with safety standards and rules remains low or neglected. Building information modelling (BIM) is used in this study to develop a safety clauses visualization system using Autodesk Revit’s application programming interface (API). The prototype digitally stores and views clauses of safety standards, such as the Operational Health and Safety Rules 2022 and Introduction to Health and Safety in Construction by NEBOSH 2008, in the BIM environment. This facilitates the safety manager’s ability to ensure that the precautionary measures needed to work at different heights are observed. The developed prototype underwent a focus group evaluation involving nine experts to assess its effectiveness in preventing FFH. It successfully created a comprehensive safety clause library that allows safety managers to provide relevant safety equipment to workers before work execution. It also enhances the awareness of construction workers of all safety requirements vis-à-vis heights. Moreover, it creates a database of safety standards that can be viewed and expanded in future by adding more safety standards to ensure wider applicability.

“…Falls from a height on construction sites [19][20][21] and fall detection have repeatedly been the subject of scientific research and technical design [8,[22][23][24][25][26]. Essentially, fall detection solutions can be divided into three main classes: wearables, devices located in the environment, and image-based devices.…”

The use of individual fall protection equipment is one of the most commonly applied methods of protecting workers whose worksites are located above the floor level. The safety of the user in such a situation depends on both the proper selection and correct use of such equipment. Additionally, aspects such as minimizing the free-fall distance before the fall arrest, as well as quick notification of an accident and efficient rescue operation, are important factors influencing safety. This paper presents a new testing method for fall arrest equipment using a test stand consisting of the Hybrid III 50th Pedestrian ATD anthropomorphic manikin and measuring set with three-axis acceleration transducers. The proposed method and test stand were developed for the design and testing of new fall protection devices equipped with electronic detection and alarm systems, for which it is necessary to determine acceleration limits in order to determine the alarm threshold. The proposed method is based on the measurement of accelerations that occur during tipping and falling from the height of an anthropomorphic manikin secured by a self-locking device. Two places of attachment of the measuring set with a three-axis acceleration sensor were analyzed at the waist belt of the manikin (abdomen and back). Moreover, the self-locking device lanyard was attached to the two points of the safety harnesses (the front and back point). The aim of the research was to check whether the acceleration values depend on the places of attachment of the measuring and anchored system, as well as to determine their maximum values. Acceleration values corresponding to fall arrest and tipping were analyzed. Limits of acceleration have been established in order to determine the threshold of alarm triggering. The non-parametric Mann–Whitney U test was used to check whether the location of the three-axis acceleration transducer and the position of the self-locking device lanyard attachment affect the value of the recorded acceleration. For results of acceleration measurements when testing the behavior of the manikin during fall arrest, no statistically significant differences were found. For results of acceleration measurements when testing the tipping behavior of the manikin, statistically significant differences occurred. This means that during fall arrest, the location of the three-axis acceleration transducer and the position of the self-locking device lanyard attachment do not matter. This work is a continuation of previous research on accelerations characterizing human body positions occurring during normal physical activities (ADL—activities of daily living).

The fall arrest belt as a piece of personal protective equipment is one of the primary methods of protection against falls. This paper uses pressure-sensitive paper to test the pressure distribution of six parts at different hanging points in static suspension and dynamic fall. The ordinary seat belt is improved by developing a wide–narrow changing belt, which promotes uniform pressure distribution. The results show that the front hanging point is better than the back hanging point, as it can minimize the pressure of the seat belt on the human body during static suspension. Using a wide–narrow changing belt to increase the contact area of the heavily compressed parts can significantly reduce the pressure and promote uniform pressure distribution. The variable coefficient of pressure distribution p of ordinary seat belts and wide–narrow changing seat belts decreased from 0.68 to 0.28. The force discrepancy in different parts fell from 143.7 to 34.8 N.
