Rescue from ice-hazards - ice diving 02/2010 On 20 February, we met us with the volunteer fire departments from Halberstadt and ways of life to a joint training on "Rescue from ice-hazards." Was completed, the course still sports divers who visited the parallel specialty "ice diving" and a tutorial on DLRG skipper, who should listen to the theoretical foundations of Eisentstehung, rescue and first aid with.
were in the two-hour theory block the subjects of "physics of Eisentstehung," "Dangers on the Ice", "Safety," "Rescue from ice-hazards", "diving under ice," hypothermia "and" first aid taught. "Then laid the Fire and divers to the lake to practice Halberstadt.
Important Interdisciplinary aspect of such training is always the acquaintance of the other units in order to know in case of a joint operation was "the others" may need and how they work.
to the weirs were first task in the light of the recently learned safety rules that need to prepare for the upcoming exercises and dives and holes in the ice to prepare.
the intrusion of a person should be simulated in a small triangular hole in the ice of one meter side length, to be saved by different methods. A large rectangular hole was needed for the Eistauchgänge and Collapse of rescue workers with their rescue sled, which brought the military from Halberstadt.
The ice cover on the Halberstadt lake was ideal for the upcoming exercises. The long frost had left the ice to grow to about 25 centimeters, so was that a safe working environment possible.
While the firefighters präpariereten the ice and the equipment for the "rescue" to clear the divers prepare their equipment and moved around, for they were to push the ice under the ice and act like the real "victims."
But before it really went off there was even a brief overview theortischen Struck on the doors, using principles and rules of a group of divers use DLRG.
The explanation of the different equipment, different combinations and their associated different uses of the diving group of firefighters and scuba divers were excited and interested in pursuing questions.
As no questions were open more, the upcoming practice of states so that each of the participants knew exactly what and how it should proceed.
The dams were given the role of savior transferred.
The divers were Victims and provided the exercises safely, but if it expected to resist, would lead to a collapse. The Safety was all fun as always at the top.
sacrifice: well secured by its signal the divers man goes to his "break point" ...
... and wait for the Savior ...
... the "sort" just have to.
But eventually they reach the unfortunate ....
... and can deliver this with the help of their comrades out of its predicament.
The dams do not always have a rescue sled. But leaders have yet usually there. Thus, in the next attempt the next heavier variant was tried: The preliminary work with ladders.
Equipped with a life jacket and backed with linen works in front of the companion site to the intrusion by advances in exchange a ladder while she is on the other, to increase their contact area.
Then she rises and moves to front of the other ladder section. (In most cases the injured person is not laughing.) Is it close enough to the accident victim to this with a conductor part to achieve, and this still able to hold herself, then she gives him head of this part (this is also backed with linen) and he is pulled out from the other comrades from the ice.
Probably the most difficult exercise is coordinating the rescue by a human chain. She is very fast, as they hardly preparation time needed, but very difficult for the rescuers and the most dangerous because they can break it quickly under cool or faster.
The easiest rescuers need to the top of the chain and have its circulation area by lying down as large as possible, make himself not to break. The backup is done by the following, on the legs.
possible to transfer a command to work before the group. If one prefers a leg, the next lead the arm that secures the leg forward. No easy task when you do it the first time.
The rescuer at the head of an asset or a lead rope with a loop, which he can throw the injured person, if not even up to the break-point approach must.
... exhausting, but in the case of an exercise and fun.
Done ... and not even a nail broken off!
At the end of the first practice session took each of the companions of the Fire Department nor the experience, as it collapses when his rescue sled.
Now they know that you can quickly when pulling ever fall into the water and by now everyone was eager to have a life jacket.
While the related rescue situations from the fire department could rest now well deserved. This pause was used by divers for a dive under the ice. Since it ice diving between sport divers and use in security issues and implementation There was no difference this course for recreational divers to the specialized course "ice diving," the association Deuter be certified scuba divers.
During this break we had for fellow firefighters to get to the back lot. When you see before diving in conditions? The ice diving illustrated as procedures and responsibilities for a divers use. It showed what divers can do and where they are reaching their limits.
came after the break, then again to an effort ... or trial of strength that had previously not been announced. to the firefighters from Halberstadt and ways of life were divided into two mixed groups, and should indicate which group the fastest an exhausted can save the ice collapsed casualty that threatens at any moment sink.
To this end, we brought you a dummy, which provided more or less lead falls faster or slower ... or swim.
was on a start signal, the dummy thrown into the water and rescuers launched their course.
Barely two minutes were needed to the casualty to to save on land and never the dummy was under water.
Both groups have done an excellent job, so that the dummy did not have to be recovered by the divers, but that only the Verschließnen the ice hole was left.
Despite that the ice was in the manufacture of the ice hole already cut as a precaution in two parts, had these parts because of the thickness of the ice huge boost. This fact made the closing of the hole to work hard.
Finally, the operation site was not secured properly, so the next day did not have to be disengaged in fact, to prove what they have learned in action.
Dr. Robert inspected once again the correctness and the last to leave the ice. Closing time!
Before we left the lake Halberstadt to a barbecue, we evaluated more from the training day behind us.
I definitely liked the high motivation and high commitment of the comrades of the Guards from Halbersatdt and ways of life and I am glad that I just this from my comrades from the diving group expected at any time.
we have all learned something from each other and take us back such common Training outside of core exercises to do to us and what we do and can know better each other, for only allowing the most perfect work together to achieve common goals as possible.
