“…Filtration efficiency for a protective face mask shows that the mask's design, materials used, and it is fit to the face are vital to point to the designer. Thus, choosing a fit protective mask for various environments is important (Ardon-Dryer et al, 2021;Bazaluk et al, 2021). The user could use this platform to select a suitable and adequate protective mask for different situations and environments.…”

Protective face mask identification is essential today to users as it is a prominent protective wearable to shield from being infected by Covid-19 viruses. Protective face masks consist of layers of fibers that can capture large respiratory droplets and microscopic particles such as viruses or dust. Thus, mask filtration efficiency results depend on the materials used for each layer. Detail about mask description and efficiency are still anonymous to users, which is vital in this COVID-19. Therefore, this paper reviews designing 3D augmented reality for the protective mask with its detail parameter and mask sizing recommendation on android mobile. About 73 articles on the protective face mask, 3D augmented reality modeling, masks inward leakage testing, breathing resistance, and measuring faces have been reviewed. The result examines the existing protective face mask, inward leakage testing parameter, breathing resistance parameters, 3D modeling techniques, mobile applications, and the application used for measuring faces. The identified result shows six recent and familiar masks with 8% of arithmetic mean for inward leakage testing. The best flow efficiency is determined a 0.3 Microns bigger than 95%. The result also shows a detailed parameter for inward leakage testing in terms of inhalation resistance and flow rate. The comparison for 3D AR parameters is identified for application type, evaluated parameter, technical support parameter, AR platform, and software. This research is significant for developing AR mobile applications that ease and transparency information to the community for safety and health issues in Malaysia.

“…The loose fit of the FFRs' facepiece to the surface of the user's face leads to the excessive suction of polluted air into the breathing zone and, as a result, a decrease in its protective efficiency (Cheberiachko et al, 2020;Bazaluk et al, 2021;Cheberiachko et al, 2022). The leakage of dust particles and aerosols through possible gaps formed between the surface of the facepiece and the surface of the worker's face is influenced by: human working positions, body and head movements, and intensity of physical activity during its use.…”

“…Maintaining the reliability of sealing is a difficult task that requires a constant search for ways to improve the design of the respirators. The main research areas include developing the facepiece customization techniques (Cai et al, 2018;Makowski et al, 2019;Pekarcikova et al, 2022) and introducing changes in the facepiece construction, including diversification of sizes, application of new materials and implementation of additional construction elements (Han et al, 2018;Mueller et al, 2020;Bazaluk et al, 2021;Rothamer et al, 2021;Okrasa, Nowak et al, 2021;Okrasa, Majchrzycka et al, 2021).The purpose of this study is to substantiate the choice of the type of elastic head straps of FFR by the criterion of their geometric shape and tension forces, which can ensure an allowable level of leakage of polluted air into the breathing zone of FFR during its use. To achieve this goal, it was necessary to establish the analytical dependencies between the geometric plane of the elastic head straps, the tension force of the facepiece and the air leakage into the breathing zone.…”

The level of occupational respiratory diseases among workers in the mining, machine-building and metallurgical industries remains high. The most common occupational respiratory disease is pneumoconiosis, which is the result of the long-term inhalation of dust. It is possible to minimize the impact of dust on the workers and eliminate such diseases in the future due to the use of filtering mask respirators designed to reduce dust infiltration into the space under the mask. For this purpose, the choice of the type of elastic bands of filtering mask respirators has been substantiated by the geometric shape and tension forces that can ensure a permissible level of leakage of contaminated air into the breathing zone of the respirator during its use. A mathematical model has been developed to describe the influence of parameters of elastomeric headgear on the protective properties of the respirator. The dependence of the change in the residual tensile strength of the elastic bands of the headband has been established, and the dependence of the volume of air suction on the area of the elastic straps at the corresponding tension force has been determined. Using the model, the dependence of the volume of polluted air inflow on the area of the elastic straps at the corresponding tension force has been estimated. The design of the innovative inserts has been offered, which makes it possible to control the tension of the elastomeric head straps of the respirator to visualize the weakening of the pressure forces responsible for maintaining a tight fit.

The research is focused on topical issues of determining the safe parameters of pit edges in the conditions of a reduced protective zone near a critical infrastructure facility. Considering the extraction of soft rocks that are prone to landslides and deformations, the permissible safe distances from the upper edge of the pit on the surface to the industrial infrastructure facility are determined and established. Based on the physical and mechanical properties of the rocks, the parameters of geomechanical models of the pit edges were developed and substantiated to study their stability and stress state in the conditions of the Eastern section of the Chabanivske clay deposit. A brief description of the deposit under study and its geological structure is given. Computer modeling was carried out to determine the safety factor, and changes in the stress state of the massif near the pit edge were determined by the finite element method. Taking into account the mining technology were determined the safe parameters of the pit edges. Safe distances from high-pressure pipelines of state importance are substantiated. A rational pit edge angle of 28 – 31 degrees is recommended, and the appropriate safety distance for the rocks of the Chabanivske deposit in the western section should be at least 95 m.
