    Respiratory protection devices, both compressed air and compressed oxygen based, are subject to certification for placing on the market. The European standards governing the requirements for certification, the manner of conducting the tests are reviewed periodically in order to increase the operational safety of respiratory apparatus in order to cope in any circumstances with the dangers to which rescuers are subjected. The evaluation of the respiratory apparatus from a practical point of view is done by the practical test of performance. The modernization of the training facility according to the latest standardization regulations regarding the practical performance tests is necessary for the certification activity of the respiratory apparatus but it is also useful for the activity of training rescuers, having the role of harmonizing the request of the respiratory apparatus with the effort to which the rescuers are subjected

    The previous events in the industry reflect the need to take action to stop or at least slow down the development of damage and to prevent or reduce, as far as possible, their extent. In the case of breakdowns in industrial technological processes, their management requires, in addition to plant maintenance personnel properly trained for such situations, the participation of specialized personnel for interventions in hazardous environments. To form an image, the intervention is described as a set of actions in the facilities of a technological flow in which an event out of technological control was triggered, which aims to stop the negative consequences. The systemic approach of the correlation of hazardous substances in connection with the hazardous environment, of the relationships between the hazardous environment, constructions, technological installations and personnel as well as the identification of the effects of hazardous environments allows the crystallization of a relational analysis of hazardous environments. In this context, rescuers involved in the liquidation of damage must have a high degree of practical and physical training. During the training / interventions, rescuers have the opportunity to constantly monitor their physiological parameters through wearables. This paper aims to identify quantifiable biometric parameters for rescue and rescue personnel in the context of relational analysis of hazardous environments

    Household landfills can be important sources of air quality contamination if they do not comply with technological sorting and storage procedures. Also, workers' exposure to environmental hazards endangers their health over time. A significant amount of household waste is stored in cells, monthly, after a sorting process that leaves a considerable ecological footprint. In this study we analysed air quality at the boundary of a compliant household landfill, as well as the quality of work environment of landfill’s workers. To do this, we performed measurements on two levels (air quality and work environment) over three months, following different phases of waste disposal and different activities involving workers serving the facilities. From an applied perspective, results obtained from research activities provide clear answers to questions related to ways in which environmental components are affected by waste storage activities, and workers are exposed to professional noxious. Results show that the landfill deteriorates environment quality, over time, as well as health of workers. Topic relevance is in connection with its potential future contribution to development of knowledge in the approached field, to be able to quantify progress, once integrated systems for modern ecological collection and storage have legislative regulations

    Antimicrobial peptides (AMPs) are small peptides with less than 50 amino acids and are part of the innate immune response in almost all organisms, including bacteria, vertebrates, invertebrates and plants. AMPs are active against a broad-spectrum of pathogens. The inducible expression of AMPs in plants is a promising approach to combat plant pathogens with minimal negative side effects, such as phytotoxicity or infertility. In this study, inducible expression of the de-novo designed AMP SP1-1 in Micro Tom tomato protected tomato fruits against bacterial spot disease caused by Xanthomonas campestris pv. vesicatoria. The peptide SP1-1 was targeted to the apoplast which is the primary infection site for plant pathogens, by fusing SP1-1 peptide to the signal peptide RsAFP1 of radish (Raphanus sativus). The pathogen inducibility of the expression was enabled by using an optimized inducible 4XW2/4XS promoter. As a result, the tomato fruits of independently generated SP1-1 transgenic lines were significantly more resistant to X. campestris pv. vesicatoria than WT tomato fruits. In transgenic lines, bacterial infection was reduced up to 65% in comparison to the infection of WT plants. Our study demonstrates that the combination of the 4XW2/4XS cis-element from parsley with the synthetic antimicrobial peptide SP1-1 is a good alternative to protect tomato fruits against infections with X. campestris pv. vesicatoria

    Lowering the level of occupational exposure to noise in areas neighbouring compressor halls

    A general problem in the vicinity of industrial compressors is the noise generated in the working environment by their operation. A large number of workers suffer from hearing problems caused by exposure to high levels of noise in the workplace. Thus, legal provisions regulating occupational noise exposure aim to reduce the risk of hearing loss by reducing noise level, the most effective measures being those applied directly to the noise source combined with the use of hearing protection. Quantification of noise exposure level and mitigation of occupational hazards generated by it at each workplace is required in order to prevent accidents and occupational diseases. The current paper analyses how noise generated by industrial compressors influences worker’s activity. Prevention of noise exposure must be based on noise level measurements. In this sense, the purpose of the paper is to analyse noise measurements performed at a compressor hall and to compare the values obtained with limit values set by in force legislation, in order to apply the best technical organizational methods for lowering noise exposure and increasing acoustic comfort in order to improve working conditions of those working in the compressor hall

    Work implies interaction of several components such as equipment, work environment, work load and human factor. Prevention of work accident and occupational diseases is mainly based on knowledge and assessment of occupational risks associated with each workplace. Psychosocial risks are usually caused by stress, thus being greatly influenced by individual perceptions. Identifying psychosocial risks is based on the analysis of individual reactions to external factors and activities. Worldwide, work related stress is seen as a major present-day challenge, faced by occupational health and safety specialists. Considered at organizational level and not as individual issues, psychosocial risks and stress can be managed to the same extent as any other occupational health and safety risk. The growing issue of protecting emergency workers against occupational health and safety risks has been highlighted as a priority by many experts. Demands on intervention and rescue personnel, as well as occupational health and safety risks will increase as they face larger events both in number and magnitude and severity. The current paper will summarize key issues related to work-related stress and will discuss how stress at work can be best managed in the context of intervention and rescue activities in toxic / flammable / explosive environments

    Stress and psychological resilience in intervention and rescue activities

    Nature of intervention and rescue personnel activity places them at the top of professions that face a considerable number of occupational health and safety risks. Often, this occupational category does not face a single safety risk, but a complex combination of risk factors, including unpredictability of situations in which they are required to work. Emergence of stress and other psychosocial risks in work processes requires the implementation of an anticipatory attitude and a constant level of vigilance to identify and evaluate them. In intervention and rescue, the issue of regulating and self-regulating the individual’s behaviour is essential, as exceptional acts performed in unusual conditions require adaptive mechanisms as close as possible to perfection. Developing resilience should focus on amplifying already present strengths (physical and mental characteristics and abilities), rather than managing negative effects of operational stressors. The current paper presents a theoretical approach of the concept of resilience, appliable to intervention and rescue activities and suggests several ways to develop rescuer’s resilience

    In any given field, the psychological examination represents a prerequisite for ensuring that the work process is properly and appropriately directed towards increasing its efficiency. An important aspect of the psychological examination is to identify risk and protective factors associated with developing and maintaining emotional and behavioural problems. Special conditions resulting from emergency situations are likely to lead to physical and emotional tensions. In some intervention and rescue personnel these are accompanied by mobilization of internal resource, while in others they can generate inadequacy phenomena and symptoms of mental distress. From this perspective, stress is regarded as a result of the marked disparity between environmental requirements and the individual’s response possibilities. To highlight both cognitive and behavioural coping strategies most often used by rescuers trained in NRDI INSEMEX we used two instruments, namely Strategic Approach to Coping Scale SACS and Cognitive Emotion Regulation Questionnaire CERQ. This paper displays the results of the project no. PN 16 43 01 12, study conducted through Nucleu program, implemented with the support of NASR
