Using the developed methodology and forecast assessments of the number and structures of vehicle fleets and transport work, has been carried out the assessment of potential reduction for greenhouse gases (GHG) emissions by all means of transport for the period up to 2030, and measures to this reduction achievement. It has been established that GHG emissions by transport in 2030 can be reduced in comparison with 2015 from 286.0 to 261.2…282.0 million tons of CO2-eq. that is 20…26% more than in 1990. To achieve the target level of GHG emissions by transport in 2030 (70…75% of the 1990 level) is possible only if the entire car fleet of Russia (66.3…73.6 million units) will consist by half of hybrid vehicles and by half of electric ones. The main measures for reaching the stabilization path of GHG emission volumes by the transport complex, and then reducing these volumes by 5…12% in 2030 are follows: introduction of a carbon-based transport tax on all types of vehicles; introduction and tightening of specific (per unit mileage) standards for fuel consumption and CO2 emissions of single vehicles; measures for substitution of transport whose age exceeds 10 … 15 years, by electric cars, hybrids, and vehicles that run on alternative fuels, the use of carbon-free transports in the vehicle fleet. The formed system of GHG emissions regulation should foresee a differentiated approach to various sectors of the economy (taking into account objective differences in their development level, and technological possibilities on GHG emissions reducing), and should not thwart goals of intensive development for economy with gross domestic product growth rates exceeding the world average ones.","PeriodicalId":273685,"journal":{"name":"Safety in Technosphere","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114886500","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A fire safety index for personnel escape routes has been introduced, and models for assessment the probability of personnel evacuation have been used. Have been concerned problematic issues related to humans’ behavioral feature during fire, their moving in case of evacuation inside enclosed and confined spaces, distance of workplaces from escape routes, reliability of emergency voice alarm communication system. An approach for safety assessment of automatic fire extinguishing units containing fire-extinguishing agents which are hazardous to human health has been proposed.

The carcinogenic and non-carcinogenic risks factors have been calculated through calculated data on trace elements concentrations in the air, based on established experimentally their content in the snow cover’s solid phase. According to the total value of the inhalation impact’s danger factor the studied territories can be ranked in the following range of boilers: coal > woods >gas ≥ oil ones. The impact of these activities can be appraised as permissible and acceptable. Contributions of heavy metals into risk characteristics have been ranked. Elements Mn, Cu, Ba, Al make the major contribution to the hazard coefficient and are among the elements-indicators for ash emissions of coal boilers. For all elements with carcinogenic properties (Cr (VI), Cd, As, Be, Ni, Co, Pb) the values of individual carcinogenic risk are below 10–5 for environs of all considered boilers. Such values correspond to the negligible risk level. From a practical standpoint, the heavy metals’ emissions differentiation both by nature and content, when using different types of fuel, affects the health risk indicators and can be informative when choosing a fuel for boilers of individual housing construction.","PeriodicalId":273685,"journal":{"name":"Safety in Technosphere","volume":"129 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124235308","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In engineering calculations the noise screen is often considered as infinitely extended, so that the sound diffraction on its side edges and the noise from the parts which are not covered by the screen are ignored. The proposed complex approach in the screens design allows assay the levels of noise emanating from the parts of transport stream, covered and uncovered by the screen. Thus, the designer, in case of exceeding the set values by the noise level, can estimate from where the loudest noise comes: from the top of the screen or from its sides, including the noise from the road traffic parts which are not covered by the screen, both from the right and left sides of it. From here is emerged the possibility to rationally vary the screen’s geometric dimensions, increasing its height, or extending it in one or another direction. As a result of such design, the screen’s optimal basic geometrical dimensions are determined in terms of providing the necessary noise level in the protected area. This allows reduce the design time and economic costs for the construction of screens.","PeriodicalId":273685,"journal":{"name":"Safety in Technosphere","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121938586","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A high load axial fan and a fan with decreased rotor’s pitch chord ratio by reduction of blades number were investigated. Have been performed tests of the fan with design characteristics as follows: theoretical head coefficient Ht = 0,3, mass flow rate Ca = 0,4, hub’s relative diameter ν = 0.6, and with blades, graded on the law of permanent circulation. The area of effective adjustment was estimated by the performance factor value η* ≥ 0,8. When changing the stagger angles in a wide range from 26° to 70°, the area of highly economical work was in variation ranges 0,26–0,78 for the mass flow rate Ca , and 0,24–0,5 for the theoretical head coefficient Ht accordingly. Tests of fans with a reduced blades number in the rotor (12 instead of 16 for the original fan) has showed that under the same stagger angles the fan’s high-efficiency operating mode is approximately in the same range of Ca variation at slightly reduced values of theoretical head coefficient. Maximal performance factor has increased on 2.5%. Decreasing the number of rotary blades, simplifying the turning mechanism and reducing the weight are possible in the design of fans with increased values of aerodynamic load coefficients.","PeriodicalId":273685,"journal":{"name":"Safety in Technosphere","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127192390","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
