The diver controls the flow rate of the water from a valve at the hip, allowing control of the warmth of the suit in response to changes in environmental conditions and workload. Tubes inside the suit distribute the water to the limbs, chest, and back. Boots, gloves, and hood are also supplied with hot water from the ends of the distribution hoses.
design using water traps and drainage arrangements (on some rebreather designs), introducing a semi-permeable membrane to block water from the scrubber. Avoid aspiration of water from loop by recognising the characteristic gurgling sounds and increased breathing resistance, and taking appropriate action by bailing out or draining the set if ...
Immersion in water and exposure to cold water and high pressure have physiological effects on the diver which limit the depths and duration possible in ambient pressure diving. Breath-hold endurance is a severe limitation, and breathing at high ambient pressure adds further complications, both directly and indirectly.
The tops of waterfalls are especially dangerous because of fast moving water and smooth, slanted rocks. Rubber soles grip poorly on slime, compared to felt soles, crampons, or hob-nailed boots. Precautions include being aware of the danger, using hiking poles, loosening packs straps to lower gravity and in case of becoming submerged, and ...

The water might be a cool respite for your furry friend in Florida's stifling heat. But dangers are everywhere, aside from the obvious like gators. Water might be fun for your dog, but dangers are ...

As it turns out, much like iced tea, plain old ice water hides all sorts of hidden dangers for your health.
