Paperback. Zustand: New. Print on Demand. This book delves into the permeability of oxygen breathing apparatus to gases and vapors. Prior experiments on gas permeation through rubber are examined, along with tests conducted by the author on various fabrics to determine their suitability for use in breathing bags. The author disc…overed that fabrics commonly used in breathing apparatus were permeable to gasoline and benzene vapors, posing safety concerns. The book explores alternative materials, such as fabrics containing glue-glycerine mixtures or pyroxylin varnish, which exhibited promising results in resisting permeation and ensuring the safety of oxygen breathing apparatus users. This research contributes to the advancement of safety measures in the use of oxygen breathing equipment, particularly in environments with high concentrations of organic vapors. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item.

Paperback. Zustand: New. Print on Demand. This fascinating book discusses the development and testing of gas masks and respirators designed to protect train personnel from the potentially lethal effects of locomotive smoke inhalation in railroad tunnels. During the early 1900s, engineers and firemen suffered in enclosed, smoky,…dangerous environments, even occasionally succumbing to toxic gases. The author provides historical context for the problem and delves into the chemistry of combustion and the physiological effects of smoke inhalation, including carbon monoxide poisoning. A review of various mask designs and the results of extensive testing follow, with the author concluding that a small, pocket-sized canister containing charcoal and soda lime offered the best protection against the irritant gases and smoke, as well as the dangerous carbon monoxide.

Paperback. Zustand: New. Print on Demand. This book explores the development of sugar-tube methods for quantifying siliceous dust in air, a significant factor in the health of miners. The introduction of new methods based on electrical precipitation, optical measurement, and weight determination enabled critical evaluation of th…e efficacy of sugar filters. The author presents the results of comprehensive studies on factors influencing filter efficiency, including tube dimensions, sugar depth, particle size, and moisture content. The book also includes a critical analysis of results obtained using both low-resistance tubes with granulated sugar and high-resistance tubes with pulverized sugar. The insights gained from these experiments provide valuable guidance for optimizing sugar-tube design and improving the accuracy of dust measurements in various industrial settings, particularly in mines where dust inhalation poses significant health risks.
