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. Filtration technologies, particularly in self-contained breathing apparatuses (SCBAs), are analyzed for their effectiveness in removing toxic particulates and gases. Ergonomics and weight distribution are also highlighted, emphasizing their impact on user fatigue and mobility. Furthermore, the durability of materials under high temperatures, mechanical stress, and prolonged use is considered. Innovations in sensor integration and real-time monitoring are explored, enhancing safety through early detection of equipment failure or environmental hazards. Finally, this review underscores the need for compliance with international safety standards and rigorous training to optimize the efficacy of breathing apparatuses in life-critical scenarios
