Environmental measures to reduce air pollution on the territory of a specialized facility

A detailed narrowly focused survey was carried out on one of the three zones of the technological infrastructure of a specialized facility - a hangar for aircraft (LA). A general list of pollutants (SV) released into the atmosphere at the 2nd site - the hangar of a special facility was established. Generators – installations and constructs of polluting components on a specific area of stationary and mobile type, which operate at a special facility, are fixed in the selected sectors. In accordance with the nature of the released components and the nature of the emission source (stationary or mobile type), the 2nd site is divided into 4 sectors. The measurement by sectors was implemented and the concentration of emissions was calculated according to the recommended regulatory acts of the Russian Federation. Indications of the concentration of a number of substances above the regulated MPC for 2 sectors of the 2nd site for the energy and test site of the special facility have been established. In connection with the recorded results, techniques and procedures of organizational and technical regulations that contribute to minimizing the accumulation of pollutants (gases) of functioning aircraft engines are analyzed and recommended. A method of attenuation of near-Earth smoke at an interval of up to two meters from the surface where aircraft engines operate is proposed based on the analysis of environmental measures at specialized facilities. The method is based on a variation in the orientation of the outflow of gas flows from functioning aircraft engines during launch, taxiing, takeoff, landing, and passage of an aircraft (VS) along the airfield track.

A Study on Strengthening Standards for Fire Prevention of Anti-freeze Electric Heating Cable

As per the fire statistics survey of 2019, 56.5% (152 cases) of the entire fire accidents (269 cases) caused by heating cables were due to electrical factors. Therefore, in the present work, the electrical factors responsible for heating cable fire have been analyzed, and fire prevention measures have been demonstrated through related reproduction experiments. According to heating cable fire statistics, the fire in anti-freezing appliances (heating cables), except for fires caused by electric cable arcing and other unknown factors, can be classified into four types based on installation configurations. These configurations have been classified and tested according to the Technical Regulations for Electrical and Telecommunications Products and Components (K 10013). The results of a comparative experiment on anti-freezing appliances (heating cable) revealed that the configuration “a type of water pipe with a heating cable wrapped around the water pipe and insulation on the outside” showed the highest temperature among the four installation arrangements. Additionally, the maximum difference between the test temperature (K 10013) and the actual temperature was 40 ℃.

Diagnostics of counterfeit food products

In Russia, the concept of counterfeiting is defined as “Counterfeit food products are food products that are deliberately modified (fake) and (or) have hidden properties and quality, information about which is deliberately incomplete or unreliable” [5]. According to this definition, the main sign of counterfeiting is the willfulness of counterfeiting or willful concealment of information about the properties of products that are not obvious to the buyer. For laboratory testing activities, counterfeiting is basically one of two possible identification results, i.e. compliance or non-compliance of products with the requirements established by the technical regulations of the Customs Union, legislative, regulatory legal acts of the Russian Federation. The most commonly identified nonconformity, in addition to food safety requirements, is an unreliable composition.
