Improving the process of occupational risk ­management according to the Haddon matrix

Abstract

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.
