Opis:: Horizontal Directional Drilling (HDD) technology is a highly complex process connected with high risk and uncertainty due the high variability underground strata, often limited access to specialised equipment, dynamic natural environment, technical disruptions, human factor and changes in economic environment that further complicate the gathering of reliable information and data. This work presents a new risk evaluation model tailored for HDD technology, in which failure mode and effect analysis (FMEA) modelling were applied. This paper focuses on 15 human risk factors and 9 equipment risk factors in HDD technology. The proposed approach takes into account not only the probability of the risk factor occurrence, but also its severity and the possibility of detecting faults, which were not clearly separated and analyzed in the previous works. Application of the proposed model shows the relationship between occurrence, severity and detection for the analyzed failures. Moreover, many detection possibilities for the identified failures were presented. The calculated risk priority numbers allowed to rank HDD failures and identify the most critical risks for which one should look for risk treatment possibilities beyond risk cause reduction, such as risk effect reduction, risk transfer, risk elimination or active risk retention.

Opis:: Introduction. Weed control is one of the most important issues in the maintenance sectors of both agriculture and green areas. Small tools are employed for controlling grass and other growths on steep verges and river banks. This leads the operators being exposed to many risks among which vibration is one. The purpose of this study is to measure and evaluate hand-arm vibration and to verify the daily exposure to which workers are often subjected while weeding. Materials and method. Two cutting heads, a brush knife and a mowing head were compared. Both were mounted on the same cow-horn brush cutter. The vibration total value was expressed as the root-mean-square (rms) of three component values according to the axes X, Y and Z. The signal was frequency weighted using the weighting curve Wh, as described in the ISO 5349–1 (2001) standard. In addition, the daily vibration exposure was calculated and compared with the thresholds set by EU Directive 2002/44/EC (2005). Results. The obtained results showed that the exposure action value (EAV) of 2.5 ms-2 was exceeded while using both cutting heads. The exposure limit value (ELV) using the brush knife also exceeded 5 ms-2. Conclusions. The results highlighted important aspects in terms of exposure values that should be considered with the view of preventing the risk of Hand-Arm Vibration Syndrome (HAVS) to which the operators who frequently use these tools are exposed. Specific measures should therefore be taken to protect the exposed workers.

Opis:: Several empirical studies of the social construction of risk have been conducted within the risk study paradigm but little attention has been paid so far to the flip side of this process, i.e., exclusion of risk from social consciousness by deliberately or involuntarily rendering it invisible, disregarding or marginalising it. This article, based on the concept of risk proposed by Ulrich Beck, Mary Douglas and Aaron Wildavsky and the findings of the sociology of scientific ignorance, introduces the “risk-concealment category.” This category applies to the mechanisms and processes underlying the social definition and construction of risk. It then presents the main functional areas of the mechanisms of risk-concealment in social practice and identifies the basic types of mechanisms which can be found at various stages of social risk definition and which lead to the social construction of the sense of security. The status of this text is projective and the possible paths of further exploration of the subject are outlined. The purpose of this article is to suggest a new research area focusing on the various aspects of risk-concealment and the underlying mechanisms, rules and action strategies. The mechanisms of risk assessment, political-economical risk definition and risk discourse are discussed.

Opis:: Ensuring fire safety in rolling stock is related to the use of materials and products that meet the required fi re properties presented in particular in the EN 45545-2 standard. However, there are situations in which the fi re protection guidelines cannot always be met due to other requirements, e.g. those related to the safe use of the material or component or its functionality in the vehicle. This paper outlines the principles enabling materials/products to be approved for use in rolling stock in such cases, based on the functional necessity of their application according to clause 4.7 of EN 45545-2. The possibilities of approving components under this clause should be subject to thorough analysis to ultimately determine the risk of their use, in accordance with the principles of the Common Safety Method relating to risk evaluation and assessment.

Opis:: The study deals with landslide threats in a low-relief region which exemplifies an area rarely perceived as prone to such geohazards. Actually, in the gently undulated landscape in the vicinity of Koronowo at the Brda River (South Pomeranian Lake District, northern Poland) intensified landsliding was observed in the recent years. The field mapping and examination of air photos showed that endangered terrains are fairly extensive and cannot be limited to initially identified slope failure incidences (hot-spots). The devised landslide susceptibility and hazard map is an outcome of predictive modelling using empirical likelihood ratio function (LR) with respect to seven evidential layers: elevation, slope angle, slope aspect, flow accumulation, surface deposits, depth to glacial raft, land cover as well as the landslide scars. The values of potential losses were calculated based on the mapped land-use categories and current market prices of estates and services. The final map, which resulted from combining landslide hazard with potential losses, shows damage propensity in a spatial scale of the town surroundings. It is meant as a supportive tool for decision-making with regard to allocating funds for stabilization measures or planning placement of new investments. On this background, stabilization solutions for selected sites are assessed in a cost-benefit context.

Opis:: This article addresses selected technical and organization aspects of risk mitigation in the oil port installations with regard to functional safety requirements specified in standards IEC 61508 and IEC 61511. The procedure for functional safety management includes the hazard identification, risk analysis and assessment, specification of overall safety requirements and definition of safety functions. Based on risk assessment results the safety integrity level (SIL) is determined for consecutive safety functions. These functions are implemented within industrial control system (ICS) that consists of the basic process control system (BPCS) and/or safety instrumented system (SIS). Determination of required SIL related to required risk mitigation is based on semi-quantitative evaluation method. Verification of SIL for considered architectures of BPCS and/or SIS is supported by probabilistic models with appropriate data and model parameters including security-related aspects. The approach proposed is illustrated on example of oil port installations. In final part of the article the insurance aspects are discussed in managing risks, as some risks are to be transferred to an insurance company.

Opis:: In manufacturing environments, health and safety in the workplace is very important for all employees to work efficiently and productively. Ergonomic risk factors can have a negative impact on workers when performing their tasks at work. And generate costs for enterprises due to sickness absence, reduced quality. Therefore, ergonomic assessments of workstations should be widely used. The paper presents an ergonomic risk assessment using computer modeling and simulation based on a palletizing station as a case study. The palletizing station was modeled in a virtual environment using DHM Process Simulate Human. The DHM was used to perform an ergonomic assessment of the worker’s posture using the RULA method. The Picking activity was qualified to action category 3, while Placing on a pallet - to the fourth action category. The Ishikawa diagram was used to diagnose the causes of ergonomic risk to musculoskeletal disorders, which allowed for the formulation of recommendations. Recommendations relating to changes in the layout of the workplace were applied in DHM. The ergonomic assessment of the operator working postures after the ergonomic intervention showed an ergonomic risk reduction. The Picking and Placing on the pallet activities were classified to action category 2.
