The BBC reports that a former Thai Navy diver died yesterday through running out of oxygen himself on the return trip from bringing oxygen tanks to the twelve trapped Thai schoolboys and their coach.
The round trip through the flooded tunnel, which in one portion is too tight to allow passage wearing scuba tanks takes eleven hours. (!)
The party has been trapped for two weeks on a ledge surrounded by water and they need constant resupply to avoid running out of oxygen.
Meanwhile, it is the monsoon season and further flooding is expected.
A former Thai navy diver has died while taking part in efforts to rescue 12 boys and their football coach trapped in a flooded cave in Thailand.
Petty Officer Saman Gunan lost consciousness on his way out of the Tham Luang cave complex, where he had been delivering air tanks.
The boys have been trapped for nearly two weeks in a chamber in the cave.
They ventured in while the cave was dry but were caught out by a sudden deluge of rain, which flooded the system.
The group was found by British rescue divers after 10 days in the cave, perched on a rock shelf in a small chamber about 4km (2.5 miles) from the cave mouth.
Teams of Thai and international divers have since supplied them with food, oxygen and medical attention, but there are mounting concerns about the oxygen level in the chamber, which officials said had fallen to 15%. The usual level is 21%. …
The death of Saman – a highly trained diver – on Thursday underscored the danger of moving from the chamber to mouth of the cave, and raised serious doubts about the safety of bringing the boys out through the cramped, flooded passageways.
The diver died after losing consciousness in one of the passageways, said Passakorn Boonyaluck, deputy governor of the Chiang Rai region, where the cave is situated.
“His job was to deliver oxygen. He did not have enough on his way back,” Mr Passakorn said.
He said that Saman’s dive partner tried to revive him but could not, and his body was brought out of the cave.
