Pressure Sack Saves Divers’ Lives (May, 1934)
Pressure Sack Saves Divers’ Lives
WHEN deep sea divers must be pulled up rapidly, without time to accustom themselves to the change in pressure, they become very sick. A German inventor has devised a pressure sack for this emergency. Divers are placed inside it as soon as they are pulled up, and kept under a gradually diminishing pressure for several hours. Iron chains surround the sack.
When there is not sufficient time to get a diver into the pressure sack, compressed air can be forced into his suit. Ropes are used to prevent suit from bursting.
