Life throw line
The rescue line (also: (rescue) throw bag ) is an aid in water rescue . It consists of a bag with a float sewn into the tip. Depending on the size, the bag contains 15 - 35 m of buoyant line, which can withstand a load of approx. 5000 N (≈ 500 kg), with a loop at each end. One end of the line is firmly connected to the bag. The sack is usually closed with a push button. Newer models have a "Tenax safety lock".
application
The life throw line is used in a similar way to the life ball . To help someone who has had an accident, the rescuer takes the noose in his hand, opens the sack and pulls out about 2 m of line. Then, depending on the situation, the rescuer can throw the sack to the casualty with a shock throw or a blow throw. The casualty can then hold on to the float and be pulled ashore by the rescuer.
If the throw was unsuccessful, the casualty has usually drifted away in flowing water and cannot be caught. At whirlpools, weirs or standing water, the line can be pulled in again and a new cast can be made. In order to save the time-consuming re-tamping, the rescuer can fill the now empty sack with water and take the line loosely rolled up in his hand and quickly throw it again. The range of the new throw is, however, less than with a stuffed throw bag.
Whitewater rescue
The lifeline can also be used for current rescues to quickly secure or rescue a swimmer, to rescue a kayak or to quickly build a bridge over the river. In order to use the rescue line, the rescuer looks for a quiet area in the white water where he can also find a safe stand. Then he makes eye contact with the casualty and calls out: "Rope". The rescuer then tries to throw the rope just before the casualty because the casualty is drifting faster than the rope, but if in doubt he should throw too far rather than too short. When the casualty has grasped the rope, the rescuer can pull the casualty out of the water. He should take the rope into the shoulder protection.
advantages
- Good casting properties
- Easy to handle
- Ready to use quickly
- Easy to stow away
disadvantage
- The casualty must be conscious.
- Usually not a big buoyancy effect
- Limited operational radius
Floating line
The throw line is always designed as a swimming line. Is used polypropylene which l is with a density of 0.9 kg / lighter than water and thus float on the water surface and is not so easily caught in the propeller. Polypropylene has the disadvantage that it has poor edge and shear strength and therefore must not be guided over hard or sharp edges.
