The fire-resisting rope descending device consists of hooks (or rings), slings, ropes and speed control, etc. It is a kind of safety rescue device that allows people to slowly descend along the rope (belt). It can be installed in building windows, balconies or flat roofs, etc., with special installation equipment. It can also be installed on high-lift fire engines to rescue the victims in high-rise buildings.
At present, the rapid development of China's fire emergency rescue equipment capacity and high-rise buildings is seriously out of balance. First, the equipment's lifting height and long-range capability are far behind the height development of high-rise buildings. The existing fire water tanker sprinkler fire extinguishing capacity is only 8 layers. Building height, the highest lift capacity of the highest ladder truck is only about 15 floors. For higher high-rise building fires, these emergency rescue equipment can only be “look at the buildingâ€; second, the equipment is bulky and has poor maneuverability and is affected by roads. The surrounding environment of traffic and buildings is seriously affected, and the timing is often delayed due to complicated terrain and obstacles. Third, the rescue capability of the equipment is poor. The existing ladder truck can only rescue 2 to 3 people at a time. Once a high-rise building fire is encountered, it cannot be satisfied. The actual rescue needs at the scene.
Fireproof lifeline operation method:
1 Fix one end of the fireproof lifeline to a firm object and throw the fireproof lifeline down the window to the downstairs.
2 Hold the fireproof lifeline with both hands. Hook the window sill with your left foot and the outer wall of the right fin. After the person is stable, move your left foot out of the window.
3 When the legs are slightly bent, while both feet are slamming against the wall, both arms are straight and the hands are slightly loose. The two eyes look down and slide down along the fire-resistant lifeline.
4 When approaching the ground, the right arm bends forward and the leash legs are slightly curved. The tip of the two toes touches the ground first.
Fireproof lifeline use and storage precautions:
1 The rope can not be subjected to overloaded impact or load during use. Otherwise, strand breaks or even rope breakage will occur.
2 should be stored in a dry and ventilated place in order to prevent mildew.
3 rinse after use. After warm water should be placed in a dry and ventilated place to dry or dry, avoid prolonged exposure.
4 Check the groundwork and if it is found that the rope has worn out or has broken 1/2 or more, stop using it immediately.
5 The user should check the weight regularly, if there is no broken stock or damage, they can continue to use.
6 When the fire-resisting lifeline is in storage, avoid the rope from coming into contact with sharp objects. If acid or alkali is attached, rinse immediately and dry it.

Fireproof lifeline is a rescue or self-help tool
The fire-resisting lifeline is mainly used as a rescue or self-rescue tool that the firefighters personally carry. It can also be used to transport fire-fighting rescue equipment. It can also be used as a marker during fire reconnaissance. In some large-scale factories and mines caused by large-scale smoke due to fire, they can also be used for trapped people to escape. The currently used fire-resisting lifelines are mainly refined hemp ropes, which have a diameter of 6 mm to 14 mm and a length of 15 to 30 meters. Fire-fighting lifelines for firefighters generally use 2.6 mm aviation steel cores. Small diameter fire-resisting lifelines are often referred to as throwing ropes, guide ropes, or standard ropes, and large-diameter fire-resisting lifelines are referred to as safety ropes.
