Abstract
Purpose. To analyze the existing systems and means of determining the minimum breakthrough time of gas filters, to establish their advantages and disadvantages. Methodology. The analysis of the effectiveness of means of determining the minimum breakthrough time of gas filters was carried out according to five criteria: ease of use, functionality, effectiveness, reliability and adaptability, which are the main indicators of the quality of any on a five-point scale, where 1 point corresponds to a lowest level of assessment, and 5 - to the highest, with the involvement of groups of experts and technical specialists, each consisting of 5 people working in the field of development and quality control of personal respiratory protective equipment. Research results. An analysis of regulatory requirements for determining the minimum breakthrough time of personal respiratory protective equipment against gases was carried out, which made it possible to establish the existence of requirements for determining the minimum breakthrough time of respirators. An analysis of six existing approaches to determining the minimum breakthrough time of gas filters was carried out, and it was shown that the approach of determining the term of protective action based on smell cannot be used in production conditions. An analysis of the effectiveness of approaches to determining the minimum breakthrough time of gas filters was carried out according to the five established criteria, which made it possible to determine the most promising approach to determining the minimum breakthrough time - Replacement of gas filters when the indicator is triggered. Recommendations have been developed regarding the use of the minimum breakthrough time of filters and the areas of application of such systems. Scientific novelty. The most effective approach to determining the minimum breakthrough time based on five arterial assessments has been substantiated. It has been found out what characterizes the consumer properties of the product: reliability, effectiveness, simplicity, adaptability and functionality. Practical significance. Recommendations have been developed regarding the use of the minimum breakthrough time of filters and the areas of application of such systems.
