Emergency Breathing Devices
Types of Devices
Personal Emergency Air Supply Systems
Personal Emergency Air Supply Systems (PEASS) are compact devices that provide breathable air in emergencies, such as fires, industrial accidents, or underwater scenarios. Examples include Self-Contained Breathing Apparatus for firefighters, escape respirators for industrial workers, and emergency escape breathing devices for marine use. These systems are crucial in ensuring safe evacuation and survival during hazardous incidents. PEASS are available through safety equipment retailers, specialized manufacturers like 3M and MSA Safety, online marketplaces, and direct purchases from manufacturers, ensuring accessibility for various industries and applications.
Snorkel-Based Devices
Snorkel-based devices are designed to facilitate breathing while swimming at the water’s surface by allowing users to breathe air from above through a tube that extends out of the water. These devices typically consist of a J-shaped tube and a mouthpiece, sometimes accompanied by a mask. Examples include traditional snorkels, dry snorkels with valves to prevent water entry, and full-face snorkel masks that cover the entire face. Applications of snorkel-based devices range from recreational snorkeling and free diving to training tools for swimmers and underwater photographers who need to stay submerged while breathing easily.
Breathing Tubes
Breathing tubes come in various forms depending on their intended use. In medical settings, they’re often clear and lightweight, used to deliver supplemental oxygen or assist with breathing during procedures. For underwater activities, snorkel tubes are typically longer and designed to stay above water, allowing swimmers to breathe while exploring beneath the surface. In industrial applications, breathing tubes are part of respiratory protection systems, connecting respirators or air purifying devices to the user’s mask or hood to ensure a constant supply of clean air in hazardous environments. These tubes are essential components in maintaining respiratory health and safety across different domains, from healthcare to leisure and industrial work.
Rebreathers
Rebreathers are advanced closed-circuit breathing systems that recycle exhaled air by removing carbon dioxide and replenishing oxygen. They enable divers to stay submerged for extended periods without surfacing. Examples include recreational models like the Poseidon Discovery, military units such as the Draeger LAR-V, and industrial versions like the Interspiro Divator MK II.
These devices find applications in recreational diving, military missions requiring stealth, and industrial settings with hazardous gases. They offer benefits such as longer dive times, reduced gas usage, and safety in confined spaces. Rebreathers are crucial for divers and workers who need extended underwater or hazardous environment capabilities.
