The article presents the results of a study on the functionalisation of synthetic textile materials with spherical activated carbon using an adhesive to create personal protective equipment based on Russian components. These materials are of particular relevance in the production of sorption and filtering personal protective equipment, which must have, along with high protective characteristics, high performance properties, vapour and air permeability. In the course of the work, the influence of the plasma of a capacitive high-frequency and low-pressure discharge on the modification of the base material was investigated. It has been proven that plasma treatment of polyester nonwoven material accelerates sorption processes, ensures uni-form coverage of fibres with a binder, which allows maintaining the material's air permeability. The results of studies of the material for the time of protective action on ammonia demonstrated the prospects for the development of Russian sorption-filtering textile material on a non-woven polyester base with a monolayer of granular activated carbon fixed on a polymer binder.

Field And Laboratory Conditions

Today, there are personal protective equipment, which due to their weight and size characteristics and design features can aggravate professional activity. This is characterized by an increase in the load on several major systems of the employee's body, including the cardiorespiratory system, which can cause the development of occupational pathology. The study of the functions of the cardiorespiratory system of humans in the process of his work is an important task in biomedical tests such as PPE, aggravating their professional activities and future means of individual protection from heavy labor and industrial exoskeletons. The aim of the study is to determine the possibility of using ergospirometry for the physiological assessment of personal protective equipment and industrial exoskeletons. Main part. In medical practice and high-performance sports, ergospirometry is considered the "gold standard" for functional assessment of the cardiorespiratory system. There are very few studies showing the use of ergospirometry for the purpose of physiological assessment of personal protective equipment. Results of research works in which ergospirometry was used in medicine, sports, as well as on the physiological and hygienic assessment of combat equipment, various types of personal protective equipment, including new promising personal protective equipment of the musculoskeletal system-industrial exoskeletons. The use of ergospirometry made it possible to register the main indicators of the human cardiorespiratory system both in field and laboratory conditions and allowed forming an objective conclusion about the dynamics of the degree of stress of the human cardiorespiratory system when using personal protective equipment and industrial exoskeletons with various weight and size characteristics. Thus, the use of ergospirometry both in isolation and in combination with other methods allows us to solve problems related to biomedical testing of personal protective equipment and industrial exoskeletons.

Relevance. Human industrial and economic activities and the related problem of emergency situations over the past decades require the new generation of skin personal protective equipment (PPE) with improved protective and ergonomic characteristics.Intention – To present technical and ergonomic characteristics of protective materials and modern skin PPE developed at the Kazan Chemical Research University.Methodology. Technical and ergonomic characteristics of universal protective insulating material LTL-1-2 and chemical protective fabrics FCM-P and TL-3 developed by employees the Kazan Chemical Research University are presented.Results and Discussion. According to the principle of protective action and the type of materials they are made of, there are filtering or insulating types of skin PPE. Insulating PPE is made of airtight materials (rubberized fabrics, polymer films) with extremely slow penetration of toxic and aggressive substances (both gaseous and liquid phases). Filtering PPE helps against chemical hazards (vapors, gases, fine aerosols and various types of dust). Air and vapor permeable materials are used for manufacturing special clothes against physical hazards (open flames, high-energy electromagnetic radiation, heat flows, etc.). Filtering PPE is normally used for routine operations in industries where exposure to harmful and dangerous factors is possible, or for accidents in areas that exclude exposure to the liquid phase. A fundamentally new combination type of skin PPE has protective properties of both categories.Conclusion. Modern protective materials and PPE made of these materials provide high protection, from a technical and ergonomics point of view, against various hazards for personnel of chemically hazardous industrial facilities.

Nanofiber Mats

The worldwide spread of coronavirus COVID-19 infections demonstrates the great need for personal protective equipment and, in particular, hygiene masks. These masks are essential for the primary protection of the respiratory tract against pathogens such as viruses and bacteria that are infectious and transmitted through the air as large droplets or via small airborne particles. The use of protective masks will continue to accompany humans for an indefinite period of time, and therefore there is an urgent need for a safe method to extend their usability by reusing them under perspective with minimal loss of protective properties. Nanofiber mats are widely used in masks and in this study the reusability of nanofiber mats is investigated by washing them at different temperatures. This paper shows the first measurements of the washability of nanofiber mats. Furthermore, the air permeability is measured, and the evaporation resistance is evaluated. According to the results of this study, the air permeability performance of nanofiber mats does not change significantly after washing, confirming the possibility of reuse.

The Impact

Abstract Introduction Preparations of health systems to accommodate large number of severely ill COVID-19 patients in March/April 2020 has a significant impact on nuclear medicine departments. Materials and Methods A web-based questionnaire was designed to differentiate the impact of the pandemic on inpatient and outpatient nuclear medicine operations and on public versus private health systems, respectively. Questions were addressing the following issues: impact on nuclear medicine diagnostics and therapy, use of recommendations, personal protective equipment, and organizational adaptations. The survey was available for 6 days and closed on April 20, 2020. Results 113 complete responses were recorded. Nearly all participants (97 %) report a decline of nuclear medicine diagnostic procedures. The mean reduction in the last three weeks for PET/CT, scintigraphies of bone, myocardium, lung thyroid, sentinel lymph-node are –14.4 %, –47.2 %, –47.5 %, –40.7 %, –58.4 %, and –25.2 % respectively. Furthermore, 76 % of the participants report a reduction in therapies especially for benign thyroid disease (-41.8 %) and radiosynoviorthesis (–53.8 %) while tumor therapies remained mainly stable. 48 % of the participants report a shortage of personal protective equipment. Conclusions Nuclear medicine services are notably reduced 3 weeks after the SARS-CoV-2 pandemic reached Germany, Austria and Switzerland on a large scale. We must be aware that the current crisis will also have a significant economic impact on the healthcare system. As the survey cannot adapt to daily dynamic changes in priorities, it serves as a first snapshot requiring follow-up studies and comparisons with other countries and regions.
