Introduction and purpose: Detergents are compounds that constitute the main component of cleaning products. Due to their varied chemical structure, they have different functions and a wide range of applications. The aim of this study is to draw attention to the problem of toxic effects of detergents on the basis of analysis of cases of detergent poisoning by patients of the Toxicology and Cardiology Ward of the Stefan Cardinal Wyszyński Provincial Hospital in Lublin. Material and methods: The study was retrospective in nature. It used an analysis of the medical records of 11707 intoxications in patients between 01.01.2013 and 31.12.2022, from which a group of individuals with a diagnosis of T55 according to the ICD 10 classification "Toxic effects of soaps and detergents" consisting of 36 cases was selected. Results: The study population consisted of 18 (50%) women and 18 (50%) men. The majority- 19 patients (52.78%) were exposed to the toxic effects of detergents accidentally. 10 patients (27.78%) were suicide attempts. Accompanying medical conditions were mostly psychiatric disorders, with alcohol dependence syndrome predominating - 9 cases (25%). The majority - 33 patients (91.67%) intoxified themselves with detergents in the form of liquids and solids by the oral route . Conclusions: Despite their usefulness in households and industry, detergents contribute to adverse health effects in situations of accidental exposure or intentional intake. In order to reduce the number of complications, preventive measures should be implemented - such as storing detergents in less accessible areas, in original boxes with retained labels, and increasing funding for psychological-psychiatric care in a crisis situation.

In the process of performing a complex of works on refueling of civil aviation aircraft, one of the key issues is to ensure flight safety by controlling the quality of aviation fuel directly during refueling operations. Currently, to ensure the purity of the refueled jet fuel, water separators with filter elements of a normalized degree of purification are installed on the aircraft refueling facilities, the operation of which in the working area provides normalized indicators of cleaning jet fuel from water and mechanical impurities. As practice shows, in the process of refueling aircraft, for various objective and subjective reasons, sometimes there are stochastic situations in which quality indicators go beyond the limits established by regulatory documentation and are not deterministic, and the subsequent state of such a system is described by values that characterize an extremely low level of jet fuel purification with negative consequences for flight safety. This paper presents a mathematical description of the functioning of water separator filters in the working area, where standardized indicators of the quality of aviation fuel are provided during the refueling of aircraft. The article deals with the issue of blocking the refueling of aircraft in the event of the appearance of non-normalized technical documentation indicators of the quality of aviation fuel, which arise due to a number of different factors that lead to negative cause-and-effect relationships for flight safety. Based on the mathematical description, an approach to creating a system for protecting and blocking the refueling process under the working name "Barrier" is proposed. Of the greatest interest for the study are typical water separator filters installed on refueling vehicles as terminal technical devices for fuel purification during refueling of aircraft.
