Repetitive movements and the speed of upper limbs increase the risk of musculoskeletal disorders. This study aimed to analyse the risk of shoulder injuries in repetitive tasks by evaluating the humerus angle, angular velocity, and angular acceleration during simulated chicken wing cutting. The study was conducted in a laboratory simulating a real environment. Thirty-six healthy right-handed volunteers were assessed using an electromagnetic tracking device, TrakSTAR, integrated with MotionMonitor™ (Innovative Sports Training, Inc. Chicago, IL) and software to collect 3-D kinematic data developed in the research centre. The equipment measured the angles performed by the upper limbs during the entire movement. The humerus angles were automatically transformed into angular velocity (°·s−1) and angular acceleration (°·s−2). Maximum angular velocities were 27.39°·s−1 (men, right humerus) and 22.39°·s−1 (women, left humerus), both below the safe limit. Maximum accelerations were 25.32°·s−2 (men, left side) and 28.94°·s−2 (women, left side); safety values for these accelerations are not established. Monotony is a risk factor, especially for the dominant side. Future studies should evaluate risk factors simultaneously in repetitive tasks. Repetitiveness exceeds the safe limit according to the OCRA method.

On 1 January 2024, a large earthquake occurred in Japan’s Noto region. Many buildings collapsed as a result of violent shaking. Electricity and water supplies were cut off, and communications were disrupted. On 5 January, four days after the earthquake, we visited Noto and conducted disaster-relief activities. This report integrates and discusses the results of the site visits, information broadcasts by public institutions, and previous research. Evacuation centers lacked water and proper sanitation, leading to health issues, including infectious diseases. Disaster Medical Assistance Teams (DMAT) were delayed in implementing infection control measures. Isolated evacuation centers faced communication and supply challenges. Infrastructure restoration, power supply, and toilet facilities at evacuation centers were delayed because of geographical challenges. It is important to have a team that can determine and carry out the necessary activities on site, even without instructions from the DMAT. It is believed to be effective to decide in advance how volunteer teams and the private sector will conduct their activities, assuming that they will be unable to contact public institutions during a disaster. In large-scale disasters, evacuees must operate evacuation centers autonomously. To achieve this, it is necessary for residents to regularly come together as a community. Systematically recording and accumulating these experiences will contribute to improved disaster prevention and mitigation planning. We hope that the experiences we obtained through the abovementioned disaster will be useful for preparing for future disasters.

The occupational health and safety of agricultural workers is a topic that has a direct impact on the agricultural sector worldwide. For this reason, investigations into ergonomic factors are relevant to the health and safety of agricultural workers. In this study, nine variables of the physical–ergonomic dimension were analyzed to determine which factors represent occupational risks for agricultural workers in Mayo Valley, Mexico. A sample of 200 people was considered. The sample was separated by gender and divided into groups according to age. A closed-ended survey was developed and validated to assess physical ergonomics variables using a five-level Likert scale. Using Principal Component Analysis, it was found that there are physical ergonomic variables that affect male agricultural workers more than female workers (the risk of carrying heavy objects, PE3, and the risk of performing repetitive movements, PE4). It was also found that certain physical ergonomic variables are not perceived as hazardous by agricultural workers (the risk of using inappropriate materials, PE9). In addition, various research findings are discussed to determine the implications and recommendations for improving the occupational health and safety of agricultural workers in Mayo Valley, Mexico.

Total quality management (TQM) is a strategic philosophy that has adopted kaizen activities which drives the business to carry out activities effectively to yield the best desired output, hence, a profitable organization. The kaizen philosophy acts as a catalyst in productivity rate and integrated management systems (IMS) which results in drastic improvements. When the nonconformity arises within the process, the accuracy of the problem solving determines quality of preventive action, therefore the preventive action should be accompanied by the opportunity of improvement from the raised nonconformance. This research seeks to add more knowledge and upgrade technology of problem-solving models relating to the integrated management systems by examining various troubleshooting models for problem solving and preventive action related to quality nonconformances, safety incidents and engineering breakdowns. Hence, the aim of this research is for troubleshooting model technique enhancement for issues related to process engineering, quality management systems and occupational health and safety by creating a model which analyses kaizen projects from the corrective and preventive action analysis of nonconformances. The proposed troubleshooting model was developed using lean techniques and risk rating tools; it was then applied to the case study company for simulation and the outcomes resulted in the closure of nonconformances and continual improvement of future projects. The proposed model is more advantageous to the manufacturing industries seeking to improve their Corrective Action and Preventive Action (CAPA) systems.

Industrial wool textile production exposes workers mainly to the biomechanical loading of the shoulder joint. In this work context, which is characterized by poor machine ergonomics, exposure to biomechanical risk factors, and variable work organization, exoskeletons could facilitate work processes or could be a valuable means to protect workers from overuse injuries. Field evaluation is essential to verify the suitability of specific devices and their acceptance by users. As part of a pilot study, we examined the short-term subjective effects of a passive Arm-Support Exoskeleton (ASE) on workers performing repetitive overhead tasks. In a textile factory, eight workers participated in the study, answering questionnaires after carrying out a work session with (ASE) and without an exoskeleton (FREE). Participants had been using the Paexo exoskeleton for 4.2±5.8 months (min 0–max 12). Subjective evaluations were collected regarding the workload (NASA-TLX) and relief (Borg’s CR10 scale) obtained from the use of the exoskeleton, satisfaction (Quebec User Evaluation of Satisfaction with Assistive Technology (QUEST)), usability (System Usability Scale (SUS)), and opinions on the ergonomics of the device (Ergonomics questionnaire). Workers reported a high workload (NASA 7.2±1.0) and assessed a 46% reduction in effort on the CR10 in ASE conditions compared to FREE. They expressed high satisfaction with most characteristics of the ASE (100% satisfied with durability and effectiveness), high level of usability (62% of scores above 80, out of a maximum score of 100), and ergonomics of the device (88±12, out of a maximum score of 110). In addition to the objective effects (electromyography (EMG) reduction) already demonstrated in a previous publication, these qualitative results demonstrate a positive perception by textile workers regarding the effectiveness, usability, and suitability of the exoskeleton. The adoption of ASE in the textile industry appears beneficial in the short term, but the impact associated with individual variables and long-term effects remains to be explored.
工业羊毛纺织品生产中，工人主要承受肩关节的生物力学负荷。这种工作环境的特点是机器人体工程学性能差、暴露于生物力学风险因素和多变的工作组织，在这种情况下，外骨骼可以促进工作流程，也可以成为保护工人免受过度劳损的重要手段。实地评估对于验证特定设备的适用性和用户的接受程度至关重要。作为试点研究的一部分，我们研究了被动式手臂支撑外骨骼（ASE）对从事重复性高空作业的工人的短期主观影响。在一家纺织厂，八名工人参加了这项研究，他们在使用（ASE）和不使用（FREE）外骨骼进行工作后回答了调查问卷。参与者使用 Paexo 外骨骼的时间为 4.2±5.8 个月（最小 0 个月，最大 12 个月）。收集的主观评价包括使用外骨骼后的工作量（NASA-TLX）和缓解程度（博格CR10量表）、满意度（魁北克用户对辅助技术满意度评估（QUEST））、可用性（系统可用性量表（SUS））以及对设备人体工学的看法（人体工学问卷）。工人们表示他们的工作量很大（NASA 7.2±1.0），与免费相比，在 ASE 条件下使用 CR10 的工作量减少了 46%。他们对 ASE 的大多数特性（对耐用性和有效性 100%满意）、高水平的可用性（62% 的评分超过 80 分，最高分为 100 分）和设备的人体工程学（88±12 分，最高分为 110 分）表示高度满意。除了之前发表的客观效果（肌电图（EMG）减少）之外，这些定性结果还表明纺织工人对外骨骼的有效性、可用性和适用性有积极的看法。纺织业采用 ASE 似乎在短期内是有益的，但与个体变量和长期效果相关的影响仍有待探索。

Wildland firefighting represents a physically and mentally demanding endeavour fraught with various risk factors. The primary aim of this study is to delineate occupational chemical exposure within the firefighting work environment on the firefront and its implications for firefighters’ health status. A systematic literature review was conducted utilising diverse keyword combinations across Scopus, Web of Science, Academic Search Complete, and ScienceDirect databases. Only English-language journal articles, real-world monitoring reports, and studies featuring samples of firefighters were considered for inclusion. Forty-one studies were analysed, with 26 focusing on firefighters’ occupational exposure to chemical agents during wildland firefighting and 15 addressing the health impairments of wildland firefighting activities. Polycyclic aromatic hydrocarbons (PAHs), VOCs, and particulates emerged as the most prevalent chemical agents in the exposure profiles of frontline firefighters. They were shown to be the main incidents of cardiovascular disease, respiratory disease, and work-related cancer. The rigorous demands of wildland firefighting have been demonstrated to significantly impact firefighter health, resulting in a notable prevalence of fatalities and illnesses. Given that an elevated number of health issues are common in this occupation, adopting advanced assessment technologies is imperative.

Protecting people from the risks associated with products is a critical concern in today’s economy. Pakistan, being the world’s fifth most populous country, lacks the framework of warning labels and therefore faces a significant gap in product warning labels. Pakistan is a representative of a number of countries that export a variety of products to Pakistan; however, warning labels on these goods are typically in English, which might mislead people of Pakistan in perceiving the hazard level. It is therefore imperative to conduct research into the non-textual and cross-cultural understanding of labels from the perspective of Pakistan. This study examined the applicability of ANSI Z535.4 in the context of Pakistan. A total of 66 (34 male and 32 female) undergraduate students with a mean age of 20.5 participated in this study. A meticulous experiment was designed using a nine-point rating scale with anchors on both sides, where one represented ‘not at all hazardous’ and nine represented ‘extremely hazardous’. Participants rated each component of warning labels, i.e., color, symbol, signal words, and their complex configurations. The results showed alignment with the ANSI Z535.4 standards for some components (i.e., colors, symbols, and signal words) and complex configurations, whereas no significant difference was found in perceived hazard levels between green (M = 3.167), blue (M = 3.591, and yellow (M = 3.652) colors, with a p-value greater than 0.05. Participants did not differentiate significantly between signal words, i.e., caution (M = 5.182) and warning (M = 5.879). Participants also did not differentiate significantly between complex configurations, i.e., safety alert–caution–yellow (M = 5.076) and safety alert–warning–orange (M = 5.197), with p-values greater than 0.05. These results state that discrepancies in the perception of warning labels exist. This study is the first of its kind conducted in the context of Pakistan, which will help policy makers to consider the findings before implementing a policy. In fact, differences in perception could result in failure to take appropriate precautions. Nonetheless, these nuances can be overcome with proper awareness through training for the people.

Fire alarm systems are an important part of the safety concept in complex buildings. For this reason, there are high availability requirements for the systems, which must be sustained by a maintenance concept. A shortage of skilled workers and rising costs in the construction and operation of buildings are pushing these concepts ever further. This study deals with proposed changes to the maintenance strategies to achieve cost and time savings in addition to an improvement in quality. As a first part of the work, the current state of research on developments in fire alarm systems and their maintenance and inspection concepts is analyzed within a literature review. The results serve as a basis for further research, which is based on a qualitative content analysis of expert interviews and standardized surveys to identify the weaknesses in current inspection strategies and future factors influencing the methods and technology of inspections through technical innovations. As a data basis for this study, expert interviews were conducted with experts from manufacturers, industry associations, and standards bodies in order to determine the possible influencing factors. To determine their relevance for the inspection, more than 40 experts were surveyed about testing the systems. The presented results show that new technical risks, such as cyber threats and networked plant structures, are insufficiently covered by current inspection strategies. Furthermore, inspection steps can be substituted by new technologies. The most important influencing factors that can be identified here are automatic self-test functions of components and remote inspection techniques of the systems. Finally, the results are discussed within the framework of a PESTEL analysis. In conclusion, it can be stated that the integration of identified impacts in future inspection strategies brings time and efficiency benefits in the operation of systems.

The construction industry has been identified as a major contributor to occupational accidents that can lead to fatalities. As a result, this study aims to evaluate the effectiveness of new safety and health regulations and revised guidelines in improving safety and health disclosures and performance within the construction industry. We retrieved safety and health disclosure reports from 25 Taiwanese construction companies between 2013 and 2020 using the Market Observation Post System website. We analyzed the data using the Kaplan–Meier method to assess the timing of disclosures and differences between larger (≥300 employees) and smaller (<300 employees) companies. We found that construction companies reported safety indicators more promptly than health indicators and that larger companies disclosed earlier compared to smaller ones. Only 45% of companies provide detailed reviews and preventative measures in their sustainability reports despite 64% disclosing occupational accidents. We found that from 2013 to 2020, more companies improved their occupational safety and health (OSH) reporting. This improvement coincided significantly with the adoption of international standards and Taiwan’s government regulations. In summary, the study found that larger companies were more likely to disclose OSH data compared to smaller ones. This suggests that company size and available resources could have an impact on reporting practices. While some progress was made, companies still struggle to provide detailed reports on major accidents, balancing transparency with competitiveness.

Unsafe roads have posed a significant threat to public health, economic stability, societal well-being, and national interests for numerous decades. Road traffic accidents constitute the primary cause of death among Morocco’s youth population. This study facilitates a comprehensive exploration of the opinions held by youth in Morocco with regard to decision-making in road safety. Through a rigorous analysis of their perspectives, the research endeavors to scientifically categorize these opinions. 97.8% of the surveyed youth strongly agree that road safety holds national importance and 58% recognize road safety as a personal responsibility. The overarching aim is to provide decision-makers with valuable insights to enhance the implementation of effective strategies and actively involve youth in shaping future road safety initiatives.
