Purpose.The aim of the study is to develop recommendations for reducing the probability of accidents during the transportation of rock by dump trucks based on the analysis of the consequences of changes in the psycho-physiological states of the driver. Methods. The study used the method of “Hazard and operability studies” and the method of “Failure Mode and Effects Analysis” including the organizational, logical and mathematical, and statistical procedures aimed at obtaining the expert assessment of hazards from professional experts based on Grabs’ criteria that affect to change the psychophysiological state of the driver while driving a dump truck, their analysis and generalization of the results in order to prepare reasonable decisions. Findings. It is established that the psychophysiological state of the driver as a manifestation of fear, anxiety, doubt, uncertainty when performing discrete work, which is associated with frequent changes in the beginning of movement and stops of the vehicle (accumulation of a large number of dump trucks, complex route plan, etc.) leads to an increase in the risk of an emergency. It is determined that the highest level of emergency occurs due to emotional manifestations, that are associated with the relationship between employees, the presence of leadership support, psychological assistance, mobbing, conflict resolution and more. Recommendations have been developed to increase the level of transportation safety through the formation of an appropriate organizational culture at the enterprise, which ultimately shapes human social behaviour. Originality. The scientific novelty lies in the establishment of the values of occupational risk of an accident while driving a dump truck by the driver, which depends not only on the probability of a dangerous event and the severity of its consequences, but also on changes in the psychophysiological state of the driver, which results from the organizational culture of occupational safety at the mining enterprise. Practical implications. Consists in the development of a procedure for qualitative assessment of the risk of an accident from the psychophysiological state of the driver during the trucking of rock in the conditions of the mining enterprise. Recommendations for improving the safety of transportation through the formation of an appropriate organizational culture of the transport process are developed. An approach of taking into account the socio-psychological climate in the organization to assess the occurrence of the incident is proposed.

Purpose. To improve the approach to the development of a safe work system, one of the important elements of the occupational health and safety management system (OHSMS) of employees at an enterprise. Methodology. The research is based on the Safe Systems of Work, which combines the content of safe procedures, which are determined taking into account the content of the workers production task when performing production activities, his/her competence in understanding the technological process and characteristics involved technological equipment. Findings. To reduce occupational diseases and industrial injuries at enterprises, it is proposed to implement the Safe Systems of Work (SSW) of 5 steps: analyse, summarize, anticipate, support, improve, which will make it possible to identify occupational risks (OR) and justify the feasibility of reducing their impact on the worker during the performance of production activities. For the implementation of each step, a corresponding procedure is provided, which allows ensuring their implementation. It is proposed to carry out the OR evaluation procedure according to the Tree Trunk Analysis model, which is a section of the trunk of a tree divided into six parts which characterize the dangerous factors that affect the activity of the employee, the functioning of the technological equipment and the environment. A feature of the proposed approach is the establishment of zones of interaction between the following components of the proposed SSW: the worker and technological equipment, the worker and the environment, as well as the environment and technological equipment, which characterize the specified external and internal factors of influence on the SSW. Originality. The approach to the organization of SSW to reduce the level of OR during the performance of production activities has been improved based on the improvement of the OR management process, the identification of external and internal dangerous factors that affect the level of OR, the probability of the occurrence of a dangerous event and its degree of severity, taking into account changes, over time, in the conditions of performing professional activities: during stable work, during an emergency situation, during an accident and during martial law. Practical value. Improved labour protection instructions or maps of safe production processes can be applied at enterprises with the aim of better perception by employees of labour safety requirements and improvement of document flow at the workplace.

The article highlights the problem of occupational safety of a technological truck driver by improving the process of determining the level of occupational risk by studying the relationships between various external and internal hazards. A spe...

The object of the study: the process of determining and managing ergonomic risks at workplaces when performing professional activities on the example of truck drivers. The problem lies in uncertainty when making decisions in occupational safety and health management systems. The hypothesis of the study was the possibility of assessing ergonomic risks in the occupational safety management systems of organizations based on the identification of regularities between the load index, typical working postures when performing operations and the intensity of joint movements. An ergonomic risk assessment algorithm was developed, taking into account the load index, which includes a sequence of eleven steps, which can be conditionally divided into three groups. The first is determination of the intensity of joint movement. The second is the determination of the impact of activity and the duration of the production task. The third is determining the impact of environmental factors. An assessment of the ergonomic risk of drivers was carried out for three types of production work: driving a vehicle, replacing a damaged wheel, and repairing a car. At the same time, the ergonomic risk assessment algorithm takes into account the worker’s individual state of health and environmental factors, as well as experience and work experience. It has been established that there is a high level of ergonomic risk during car maintenance due to the highest total load index, which is 30 % higher compared to other types of work of vehicle drivers. The practical application consists in the development of a universal check list of drivers based on an algorithm to determine the ergonomic risk of workers at workplaces, which consists of 11 steps

Purpose. Improving the process of managing occupational risk (OR) in occupational safety and health management systems, due to the distribution of dangerous factors which increase the probability of a dangerous event into several phases: before the occurrence of a dangerous event and after its occurrence. Methodology. The method of morphological analysis is used, which is based on the selection of possible solutions for individual parts of the task based on several morphological typical features important for the problem being solved, and the compilation of all possible combinations of hazardous factors and precautionary measures that will allow reducing the amount of occupational risk. Findings. A new approach to occupational risk management is proposed, which involves the division of all dangerous factors into several phases: before the occurrence of a dangerous event, after its occurrence, provision of pre-medical assistance, provision of emergency and medical care. Typical dangerous factors are defined that increase the probability of the occurrence of a dangerous event, which relate to the first phase (before the occurrence of a dangerous event), as well as dangerous factors that affect the severity of accidents and are characteristic of the second, third and fourth phases (after the occurrence of a dangerous event). A concept was developed for calculating the magnitude of occupational risks, based on the consequences of the occurrence of a dangerous event or by the type of injury with the area of responsibility of the enterprise; from the consequences of pre-medical care or the condition of an injured person with the area of responsibility of the enterprise and with the consequences of emergency and inpatient medical care or the state of loss of health of the employee with the area of responsibility of the medical institution. The hierarchy of preventive measures has been improved due to the addition of protective measures consisting of pre-medical care, emergency medical care, in-patient medical care. Originality. When assessing professional risks, it is proposed to determine the amount in accordance with the area of responsibility of the enterprise and and medical institution taking into account dangerous factors corresponding to a specific phase. Practical value. Examples of three matrices for assessing the occupational risk have been developed, taking into account the classification of the severity of the consequences for the health of the employee, which occurred immediately after the occurrence of a dangerous event (accident), after the provision of pre-medical care and after the provision of emergency and medical care. A description of preventive actions to reduce the severity of the consequences is proposed, taking into account the sphere of responsibility.

An analysis of professional risk management models according to international standards is proposed, taking into account the interpretation of the main terms (danger, risk, incident risk assessment), to build a uniform approach in occupational safety and health management systems in organizations. To solve the problem, the method of morphological analysis was used, which is based on the selection of possible solutions for assessing the technological feasibility of occupational risk management models and making a rational decision regarding the features of documenting the assessment of occupational risks using integrated approaches, which made it possible to specify the elements that form local, topological and metric spaces A comparison of the interpretation of the main terms that form models of occupational risk management was carried out, based on the requirements of the EU-OSHA Workplace Risk Assessment Guide, Guidelines for Occupational Safety and Health Management Systems ILO-BHP 2001, ISO 45001: 2018 Occupational health and safety management systems. Requirements and guidelines for application". Built in accordance with the requirements of the specified international standards, professional risk management models that take into account differences in the interpretation of terminology. The concepts of acceptability (permissibility) and non-acceptability (non-permissibility) of professional risks for their assessment are defined. It has been established that the main difference between ISO 45001:2018 and the existing international standards regarding the requirements for occupational risk management is the consideration of all hazardous occupational factors that can significantly affect both the probability of the occurrence of a hazardous event and the severity of the consequences, which requires a review of the matrix approach to assessment professional risks. Forms for documenting the assessment of occupational risk are proposed, in accordance with the requirements of the specified standards, which reflect their differences formed in the considered models. The scientific novelty consists in substantiating the impact of professional risk management models on their documentation procedure. Forms for documenting the assessment of occupational risk are proposed, in accordance with the requirements of the specified standards, which reflect their differences formed in the considered models. Recommendations have been developed regarding the relationship between dangerous factors of the organization's environment and their impact on the level of professional risks.
