How much do you know about rescue diving suits?

With the increase of comprehensive rescue missions, underwater rescue has also become a often facing task for rescuers.

 ​

Under the water, emergency responders need to face: low water temperature, high water pressure, low visibility, unknown creatures and other threats. Of course, the more important point is water pollution. Among them, the water temperature is the first factor to be considered, because when people stay underwater for too long, it is easy to lose temperature. And the heat loss of the human body is greater than the heat supply, which may cause language barriers and limb stiffness.

 

To overcome this difficult condition, a suitable rescue suit is important for the rescuer. Normally, there are two types of rescue diving suits:  Wetsuit and Drysuit. Hereby, there's some more information for references below :

 

WETSUIT

The characteristic of wetsuits is that water can flow into the clothing from the neckline, cuffs, hem and other parts, and come into contact with human skin.

Its warm-keeping principle is: when the flow of water between the human body and the suit is extremely slow, less heat is lost on the body surface, thus forming a thin layer of water between the human body and the wetsuit and the inflowing water is heated by the skin.


A warm bath environment is formed around the human body. When the water layer in the body is full and does not flow, the water outside the suit can no longer come in.
 

This requires the wetsuit to fit as closely as possible, because the closer it is to the skin, the more effective the warm water layer is.

DRYSUIT

The characteristic of a drysuit is to prevent the water from entering the clothes from the outside and keep the body dry. Drysuits can ensure that the body remains relatively dry throughout the water rescue work. At the same time, it has good effects of keeping warm, anti-soaking and anti-pollution, making it safer and more comfortable to work in water.

 

Its significant advantage is that there is an isolated air layer between the clothing and the human body to maintain the thermal performance.


Drysuits have good waterproof performance, breathability and warmth retention, produced by good abrasion resistance and tear resistance fabric. And all the entrances and exits of the drysuits are sealed in order to prevent the entry of the water. Its thermal performance is far superior to wetsuits.
