Assessment of the acceptable risk of injury in employees of the Federal Fire Service of EMERCOM of Russia

Abstract

Relevance. Occupational Safety and Health Management System (OSHMS) should be improved and regularly adjusted based on continuous analysis of hazards and current risks.Intention. Development of approaches to determining the permissible level of risks to the personnel of the Federal Fire Service (FPS) of the EMERCOM of Russia when performing occupational duties.Methodology. Cases of injuries were analyzed in the staff of the FPS when performing occupational duties. Relative frequencies of injuries were calculated in the personnel of the FPS as follows: light damage (the number of days of temporary disability ≤ 3), moderate damage (the number of days of temporary disability from 4 to 30) and severe damage (the number of days of temporary disability more than 30, the onset of disability or death). Associations between injuries in the personnel of the FPS and the complexity of fires were assessed, including amount of the fire extinguishers used.Results and Discussion. It is proposed to allocate two levels of acceptable risk of injury for the personnel of the FPS when performing official duties: the maximum risk and acceptable risk. Estimates of acceptable and maximum risks of injury to personnel of the FPS were obtained using the relative index of the frequency of injuries to personnel: acceptable risk estimates R acceptable = (5 ± 1) • 10–5 and maximum risk estimates Rmaximum = (4,4 ± 0,3) • 10–4. It is proposed to use the values of acceptable risks of personal injury adjusted for the complexity of fires extinguished to assess the effectiveness of the OSHMS in fire protection units. Options for decision-making in the framework of the Occupational Safety and Health Management Systems, depending on the actual level of injury to personnel in the performance of official duties, are considered.Conclusion. The proposed model for assessing the effectiveness of the OSHMS is based on the planning of OSHMS activities depending on the degree of implementation of the OSHMS procedures and the risk of injury to the personnel of the FPS of EMERCOM of Russia in the performance of official activities.

Safety risk assessment method of key personnel in infrastructure projects based on image data coupling identification

“…For the alarm times of non-dangerous actions, the alarm times of the proposed method are 0, which shows that the proposed method has no false alarm when judging non-dangerous actions. For the alarm times of the first, second and third dangerous actions, the alarm times of the proposed method are less than those of the methods in reference [3] and reference [4], which shows that the proposed method has higher accuracy and sensitivity in judging different dangerous action levels. To sum up, the proposed method can greatly improve the accuracy of dangerous action identification, and has better performance and effect.…”

“…In order to verify the practical application performance of the proposed method, reference [3] method and reference [4] method are introduced for comparative test, and the evaluation result is based on whether the danger alarm signal is issued or not, and the experimental results are shown in Table 2. It can be seen from Table 2 that the alarm times of the proposed method under different dangerous action levels are close to the real results, and it has better performance than the methods in reference [3] and reference [4]. The proposed method can accurately determine whether the action is dangerous or not, while the other two literature methods have the probability to determine the error and send out the wrong alarm signal.…”

“…Reference [3] puts forward an acceptable injury risk assessment method for employees of the Russian Federal Fire Department, and analyzes the cases of employees of the Russian Federal Fire Department who are injured while performing their professional duties. Reference [4] puts forward a safety risk assessment method of power operation site based on variable precision rough set.…”
