You can’t breathe water: Partnership leads to game changer for swiftwater rescuer safety.

Public Safety Institute and Submersible Systems (Spare Air) are pleased to announce the launch of the first type-approved Swiftwater Breathing Apparatus (SWBA®) for first responders to water rescue incidents. Based on Submersible Systems' highly successful HEED3, a compressed air emergency breathing system used by crews to escape ditched aircraft in water, the Spare Air SWBA® extends self-rescue time, ensures critical breathing capability, and minimizes risks in contaminated water, making it essential for rescue agencies.

Great article about out-of-air emergencies. Dive safe everyone!

Running out of air is rarely about air alone.

Gas management is a fundamental skill, and every diver is trained to understand air consumption, monitor tank pressure, know the limits of their available supply, and maintain adequate reserves. Yet running out of breathing gas remains a surprisingly common dive incident and a leading cause of diving fatalities. Out-of-air emergencies rarely stem from a single cause.

📉 Take depth, for example: Gas consumption increases dramatically as a diver descends, reducing available bottom time and increasing the gas needed for a safe ascent. Combined with exertion, extended dive times, or missed pressure checks, a manageable dive can become an out-of-air emergency faster than many divers realize.

Often, an emergency results from the accumulation of small factors, such as depth, exertion, anxiety, procedural oversights, and equipment issues that increase gas consumption, rather than one critical mistake. Even experienced divers can find themselves in these situations.

Throwbacks of some old Spare Air photo shoots - when you have been making products for over 45 years you have a lot! My favs are the neon pink and purple from the 80's!
