The Iranian threat, of course, is real, but its immediacy gets turned on and off by the Prime Minister like a faucet. In this tube the coals were placed, and when the water in the urn was hot, it could be drawn off by means of a faucet at the side. The drip-drip of water from the faucet sounded loud in the quiet.
After multiple dives per day or multiple days of diving, a minimum surface interval of 18 hours is recommended. If you had to do a decompression stop during a dive, the recommended time to wait before flying is a bit more of a gray area.
With relation to the time in this instance, it depends on the dive you are doing. I would recommend using a dive computer if you are doing deep and/or multiple dives. However, I would recommend a safe limit of at least 24 hours. Each dive training body will have their own advice on a safe time limit.ere is a passage from http://www.underwaterdivingequipment.com/scuba-diving-and-flying.html : â¦ Expert sources disagree about how long you should wait before you fly. The US Navy says that 2 hours is all you need; the US Air Force says you should wait 24 hours and the Diver's Alert Network (DAN) says 12 hours is okay.
