  Critical Parameters in the Design of Breathing Apparatus

  By Sudip Kumar Samanta, Susmita Maity, Rabindranath Jana

  Abstract: Breathing apparatuses are essential in hazardous environments, ensuring respiratory protection for workers in industries, such as firefighting, chemical handling, and emergency response. This study examines the critical parameters influencing the design, performance, and safety of breathing apparatus systems. Key parameters include oxygen delivery efficiency, filtration capacity, ergonomic design, and durability under extreme conditions. Oxygen supply mechanisms, including open-circuit and closed-circuit systems, are evaluated for their suitability in various operational contexts. …
