Chris Lemons has been a commercial diver for over 14 years, specialising in deep sea saturation diving. This form of diving involves living in the claustrophobic confines of a decompression chamber for up to 28 days at a time, commuting daily to the sea bed in a diving bell and working at depths of up to 900 feet for 6 hours at a time. In 2012, a freak accident resulted in the umbilical which provides him with breathing gas, light and heat being severed completely. He was left on the sea bed, in complete darkness 300 feet below the surface, with only the 5 minutes of breathing gas he carried in his emergency tanks and no way to protect himself from the freezing temperatures. It took his heroic rescuers over 40 minutes to retrieve him and his miraculous survival story has baffled experts ever since. His extraordinary story became the Netflix documentary ‘Last Breath’. Amazingly, Chris went back to work three weeks later and continues to dive to this day!
