What are the safety equipment and elements for fall protection at height?

The aerial work fall arresting equipment generally includes the following major components: seat belts, safety ropes, self-locking devices, steel hooks, speed differential fall arresters, buffer belts, tripods, and the like.

For the actual needs of different occasions, the above components can be reasonably matched to form a fall arrest system with high safety factor. At present, in the entire security protection industry, the configuration indicators and specifications of the brand fall protection system are relatively complete, providing a large room for security personnel to choose products. Fall prevention factor systems include: limit, position, fall prevention, etc. Techniques for preventing workers from entering areas where there is a risk of falling (such as positioning belts and safety ropes); providing a safe positioning for workers in a risk area where there is no determination of the fall factor (eg hanging below the joint and with a tensioning rope) Positioning belt on the base): A technique used to eliminate or reduce the impact of falling from a height (such as the use of fall protection safety ropes and buffer belts).

Three elements of the anti-drop system: full body harness, connecting parts, hanging points. The three elements are indispensable. Full body harness for staff, D-ring for hanging on front or back, some belts for belt positioning for work positioning or hanging tools and waist protection; connecting piece with safety cord, Safety rope with buffer belt, speed differential fall arrester, etc. That is, it is used to connect the seat belt and the hanging point. The static pulling force is greater than 15kN; the hanging point is the force of the whole set of anti-falling system, and its static pulling force is greater than 15kN. When selecting the hanging point, try to be assigned by a professional. In the case where a fall arrest system is required, it is necessary to perform a fall factor evaluation first. Falling factor = fall height / rope length. In the case where the fall factor is equal to 0 (such as a worker who pulls the rope at the connection point) or less than 1, and the freedom of movement is less than 0.6 m, a positioning device is sufficient. The fall protection system must be used for other conditions where the drop factor is greater than 1 or the freedom of movement is greater. It can also be seen from the fall factor that the whole set of anti-falling systems pay attention to high hanging and low use.
