Improving construction site safety remains a critical challenge in Saudi Arabia’s rapidly growing construction sector, where high accident rates and diverse labor forces demand evidence-based managerial interventions. This study investigated the influence of Managers’ Safety Perceptions and Practices (MSP) on Workers’ Safety Behaviors (WSB) in the Saudi construction industry, emphasizing the mediating roles of Workers’ Safety Awareness (WSA), Safety Competency (WSC), and Safety Actions (SA). The conceptual framework integrates these three mediators to explain how managerial attitudes and practices translate into frontline safety outcomes. A quantitative, cross-sectional design was adopted using a structured questionnaire distributed among construction workers, supervisors, and project managers. A total of 352 from 384 valid responses were collected, and the data were analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM) via SmartPLS 4. The findings revealed that MSP does not directly influence WSB but has significant indirect effects through WSA, WSC, and SA. Among these, WSC emerged as the most powerful mediator, followed by WSA and SA, indicating that competency is the most critical driver of safe worker behavior. These results provide robust empirical support for a multidimensional mediation model, highlighting the need for managers to enhance safety behaviors not merely through supervision but through fostering awareness and competency, providing technical training, and implementing proactive safety measures. Theoretically, this study contributes a novel and integrative framework to the occupational safety literature, particularly within underexplored Middle Eastern construction contexts. Practically, it offers actionable insights for safety managers, industry practitioners, and policymakers seeking to improve construction safety performance in alignment with Saudi Vision 2030.

Objectives: To elucidate the status of reduction in working hours following physician work-style reforms and factors associated with long working hours. Methods: A nationwide questionnaire survey was conducted among obstetricians and gynecologists (OB/GYNs) working in hospitals. The survey elucidated actual working conditions, including working hours and number of out-of-hour (OOH) shifts. To identify factors associated with long working hours, a multivariate logistic regression analysis was performed, with ≥60 or ≥80 working hours per week as dependent variables and OB/GYNs attributes (sex, age, job position, hospital type by ownership, total number of hospital beds, and regional characteristics) as independent variables. Results: Questionnaires were sent to 1,170 hospitals. Valid responses were obtained from 1164 OB/GYNs at 423 hospitals (response rate: 36%): 26.0% worked ≥60 hours per week, a reduction from 58.1% in 2019 (equivalent to over 960 hours of overtime annually), 5.4% worked ≥80 hours per week, a reduction from 41.2% in 2019 (equivalent to over 1,920 hours of overtime annually); and 46.9% worked OOH shifts ≥5 times per month. Factors significantly associated with long working hours per week included male sex, resident position, teaching duty, and number of OOH shifts. Conclusions: Although the working hours of OB/GYNs have decreased because of physician work-style reforms initiated in 2019, long working hours persist. To ensure health of OB/GYNs and patient safety, it is necessary to actively promote physician work-style reforms and advance measures aimed at the centralization of medical resources and addressing their maldistribution.

Introduction: Tinea unguium is a nail infection caused by dermatophytes, characterized by nail discoloration, thickening, and brittleness. Farmers, often exposed to prolonged wet conditions, are at higher risk of this infection. The use of appropriate footwear is recommended to mitigate this risk. However, inadequate personal protective equipment (PPE) usage makes farmers more susceptible to Tinea unguium. Research on Tinea unguium among farmers in Lojejer Village is limited, with differing result on the link between wearing footwear as PPE and the occurance of Tinea unguium. This study aimed to investigate the relationship between the use of footwear as PPE and the incidence of Tinea unguium among farmers in Lojejer Village. Methods: This study uses a cross-sectional observational design. It involved 98 respondents determined using Slovin’s formula. Data were collected through interviews and nail samples, which were subjected to fungal culture on sabouraud dextrose agar (SDA) medium and microscopic examination with lactophenol cotton blue staining. Fisher’s Exact tests were used for analysis. Results: Results revealed that seven farmers (7.14%) were affected by Tinea unguium, predominantly males (85.8%) aged 45–64 years (57.1%). Trichophyton rubrum was identified as the primary dermatophyte, with Aspergillus sp. as a contaminant. Statistical analysis showed no significant relationship between footwear usage, personal hygiene, or footwear hygiene and Tinea unguium (p-values > 0.05). Conclusion: The study found no significant association between footwear use, hpersonal hygiene, and footwear hygiene with Tinea unguium incidence among farmers in Lojejer Village

On 24 April 2021, a disastrous fire in an Iraqi hospital took the lives of 82 people. Since the outbreak of the pandemic in March 2020, incidents of oxygen-related hospital fires in various countries around the world have caused over 200 deaths, the majority of whom were patients extremely ill with the novel Coronavirus. Fires involving medical oxygen are not a new phenomenon but are more common in the operating theatre where oxygen is routinely administered. In these settings, strict safety protocols are normally enforced and surgical staff are well trained in dealing with oxygen hazards. It appears that some hospitals may not have been fully prepared for the elevated risk of oxygen-related fire in intensive care units due to the high demand for oxygen therapy in severely ill Covid-19 patients. Indeed, gas producers and public health authorities were also slow to recognize and alert hospitals to the potential dangers. Oxygen is essential to life and generally makes up about 21 % of the gases in the air we breathe. Pure oxygen reacts with common materials such as oil and grease to cause fires, and even explosions, when released at high pressures. A leaking valve or hose, and openings at interfaces of masks and tubes, when in a confined space or where air circulation is low, can quickly increase the oxygen concentration to a dangerous level. Even a small increase in the oxygen level in the air to 24 % can create a fire hazard. In an oxygen-enriched environment, materials become easier to ignite and fires will burn hotter and more fiercely than in normal air. There is also a potentially heightened risk of using ethanol-based and organic solvents as cleaning agents in an oxygen rich atmospheres. This paper will provide an overview of oxygen accident scenarios that may be relevant for hospital intensive care units, with particular reference to recent events and similar accidents that have occurred in the past. The paper will recommend that hospitals recognize their chemical risks as part of their risk governance responsibility and assign chemical risk management a prominent role in their overall management. Investigation of dangerous events to extract causes and lessons learned should be utilized to highlight opportunities for prevention as well as emergency response. The industrial gas industry also needs to actively support hospitals in adoption of more rigorous risk management approaches, building on lessons learned in chemical process safety for managing flammable and explosive atmospheres.

Highly autonomous vehicles (HAV) have the potential of improving road safety and providing alternative transportation options. Given the novelty of HAVs, high-fidelity driving simulators operating in an autonomous mode are a great way to expose transportation users to HAV prior to HAV adoption. In order to avoid the undesirable effects of simulator sickness, it is important to examine whether factors such as age, sex, visual processing speed, and exposure to acclimation scenario predict simulator sickness in driving simulator experiments designed to replicate the HAV experience. This study identified predictors of simulator sickness provocation across the lifespan (N = 210). Multiple stepwise backward regressions identified that slower visual processing speed predicts the Nausea and Dizziness domain with age not predicting any domains. Neither sex, nor exposure to an acclimation scenario predicted any of the four domains of simulator sickness provocation, namely Queasiness, Nausea, Dizziness, and Sweatiness. No attrition occurred in the study due to simulator sickness and thus the study suggests that high-fidelity driving simulator may be a viable way to introduce drivers across the lifespan to HAV, a strategy that may enhance future HAV acceptance and adoption.

Occupational Health and Safety (K3) is generally defined as the science of anticipating, recognizing, evaluating and controlling hazards arising in or from the workplace that may interfere with the health and well-being of workers, taking into account the possible impact on the environment and the surrounding community. The scope is quite broad, covering a large number of disciplines and many hazards in the workplace and the environment.The International Labor Organization (ILO) released data in 2020 that globally, more than 2.78 million people die from workplace-related accidents or diseases, which means one death every fifteen seconds Measures and strategies designed to prevent, control, reducing or eliminating occupational hazards and risks have been developed and implemented over the years to keep pace with technological and economic changes. Work and industrial accidents are all caused by preventable factors that can be eliminated by applying known and available measures and methods. This is indicated by the continued decline in accident rates in industrialized countries. Therefore, the implementation of prevention strategies offers significant human and economic benefits. However, occupational accidents and diseases are still too frequent and their cost in terms of human suffering and economic burden continues to be significant. This study discusses the level of occupational accidents and occupational diseases obtained by conducting a walk-through survey at the tofu factory "House Of Tofu" which is located at Way Halim Permai Bandar Lampung. Identification of occupational safety and health is carried out by means of a Walk Through Survey using Hazard Identification, Risk Assessment, and Determining Control techniques. The results show that there are still many potential Occupational Safety and Health Hazards and Risks at the House Of Tofu Tofu Factory that have not been identified and have a negative impact on the workers in it. Interventions against potential hazards must be carried out by employers to reduce the number of work accidents.

HAZOP analysis has become a versatile tool for industrial risk assessment and optimization in the past decades. It facilitates systematical design review with wide applications spanning across entire project lifecycle, from initial design to operation and decommission stages. Traditional qualitative HAZOP process that largely depends on historical experience and brainstorming can lead to inaccurate hazard identification and severe accident consequences. This study aims at improving the depth and accuracy of HAZOP analysis by delivering a comprehensive exploration of the critical factors and advanced quantitative approach. The impact factors were illustrated from prerequisite and assurance aspects. Prerequisite factors serve as the fundamentals of HAZOP which involve design technical details, HAZOP team management, execution strategy and HSE culture, while assurance factors denote the systematical PSI data and quantitative analytical frameworks. A classical chemical case study via semi-quantitative method was exemplified. Countermeasures and international leading practices were introduced with a summary chart at the end. Special attention should be paid to the effectiveness of safety guards and coming up HAZOP recommendations. Motivating future works can be explored such as HAZOP efficiency optimization, finer study targeting different project types, and broader industry applications. By incorporating the critical factors with integrated quantitative approach, the influence of enterprise HAZOP analysis will be more profound with enhanced accident prevention and risk awareness in the overall industrial environment.

Prevention of accidents is one of the key paradigms of occupational safety at work. The main mechanism aimed at minimizing potential hazards is a systematic review and analysis of the causal relationships of occupational injuries. The task of reducing the possible probability of injury and its consequences has a multi-factor structure, since it requires the restoration of the circumstances of the situation, their analysis and lessons learned, and the procedure for predicting industrial injuries depends on the type of mathematical model chosen and the quality of the initial data to be further analyzed. The paper analyzes sequential, complex linear and non-linear models and methods for assessing the cause-and-effect relationships of accidents, identifies key provisions and results. Based on the analysis of the scope, advantages and disadvantages, recommendations for the implementation of methods of predictive analysis of injuries in Russia are formed.

As industries continue to grow, complexities and uncertainties associated with process systems tend to increase, and so are the potential major industrial accidents with corresponding catastrophic consequences. To combat these industrial accidents around the worldwide, there is a need for a more dynamic approach to hazard identification and risk management that proactively mitigates potential exposures in real-time. Evidence suggests that a dynamic approach to risk management can identify and assess developing and increasing industry risks and prevent unwanted outcome. The Piper Alpha investigation and the derivation and adoption of safety case framework in the UK is a proven approach to mitigate major accident hazards for the front-end design of high-risk process facilities, throughout their lifespan. With the increasing complexity of process systems, dynamic risk management as a next-generation risk management approach is required to ensure operational safety. This study aims to stimulate discussions on the novel dynamic risk management approach, leveraging advanced technologies such as artificial intelligence and the 4th Industrial Revolution as a new risk management pathway for industrial accident prevention.

The explosion is one of the most serious safety incidents occurring in the application of the gas methane in industrial process. The new developments in attenuating the destruction and environmental hazard of this explosion are conducted using the combined inert gas and ABC dry powder. The explosive characteristic parameters including flame configuration, velocity of flame propagation, explosion pressure, and pressure rising rate are quantified and revealed. The difference of explosion mitigation effect of ordinary and ultra‐fine ABC dry powders are examined based upon the specific surface area and the settling velocity. As the concentration of ordinary or ultra‐fine ABC dry powder increases, the explosion pressure initially increases and decreases afterwards, indicating that there is an optimal mass concentration of explosion mitigation for both powders. The effect of ignition delay time on the explosion mitigation of ultra‐fine ABC dry powder is characterized on the basis of the turbulent lever and the dry powder particle settling state. Moreover, the mechanisms of explosion mitigation with CO2 and the ultra‐fine ABC dry powder are fully revealed both on the physical and chemical properties. The present research provides basic data and theoretical guidance for prevention and controlling of gas explosion accidents.

Improper organization of production, unsatisfactory working conditions, industrial accidents and occupational diseases cause serious economic losses for the government and employers. The labor protection management system formed during the Soviet era cannot reduce occupational injuries and morbidity, does not encourage employers to improve working conditions, and requires modernization. The article deals with motivation indicators in the occupational risk management system. Much attention is paid to the hazard prevention method aimed at identifying and analyzing circumstances causing dangerous situations. In assessing the motivation indicators and competence in the production and occupational risk management system, employee’s abilities to identify, evaluate and manage occupational risks, knowledge of occupational safety requirements, personal characteristics, skills, and experience in occupational safety are analyzed. It allows for reduction of the individual occupational risk level. The article concludes that it is necessary to study scientific and methodological foundations of an informative, simple, objective and understandable ORMS which includes motivation and competence indicators, to solve actual scientific and practical labor protection problems which are studied by Russian and EU experts.
