Before using a retractable ladder, the safety of the ladder should be checked. Before use, the quality of the herringbone ladder should be checked, especially whether there are safety hazards at the brackets, cable trays, and connections. If damage is found, a new zigzag ladder should be replaced to ensure safety.
The usage method and precautions of the retractable ladder
1. Ladders should be placed on a stable and sturdy level ground, not on slippery surfaces
2. Individuals with poor mental or physical condition are prohibited from using ladders
3. When using a ladder, stand within a safe height range and leave at least one meter at the top

matters needing attention
Before using the ladder, self inspection should be carried out: there should be no cracks or looseness in the welding parts of the herringbone ladder, the binding should be firm, and the ladder feet must have anti slip leather; The screws of the zigzag ladder are not loose or deformed, the safety device is reliable, the anti slip skin of the ladder feet is intact, and the zigzag ladder cannot be used on one side.
Choose a suitable ladder before each work, and no one is allowed to stand on the highest three levels of the zigzag ladder. During work, one foot should not stand on the bamboo ladder, and the other foot should not stand on it; When using a zigzag ladder, the operator shall not stand on the top two floors of the zigzag ladder, shall not cross both sides of the zigzag ladder with both feet, and shall only work on one side; A zigzag ladder must not have two people working on the same ladder at the same time.
When going up or down the ladder, the face should be facing inward. It is strictly prohibited to use tools or equipment in hand to go up or down, and carrying heavy objects is strictly prohibited. When working on the ladder, a tool bag should be prepared.
All operations using ladders must be supervised by a dedicated person who is on the ladder and the guardian must not leave the monitoring position. Do not move the ladder when there are people on it.
When working on a ladder, regardless of height, a safety helmet must be worn and the chin strap must be securely fastened. In places where there is a point of contact for the safety belt, a safety belt must be worn. If there is no point of contact for the safety belt, other preventive measures must be taken to ensure safety before starting the work. The safety belt should be worn correctly.
When using a ladder, the foot of the ladder should make smooth contact with the ground, and the ladder body should be stable and reliable without any shaking.
The angle between the bamboo ladder and the ground during use should be around 65-70 degrees. When using the herringbone ladder, the sound of the safety should be clearly heard when pulling it open. After inspection and verification, it can be used.
When using a ladder in front of a door, measures should be taken to prevent the door from suddenly opening. When using a ladder near rotating machinery, isolation and protection measures should be taken.
In case of severe weather such as strong wind, rainstorm or other dangerous factors, it is prohibited to climb the ladder in the open air.
Daily management of ladders:
The safety officers of each section are responsible for the daily management of various ladders in their respective team areas. Regularly inspect the condition of the department's ladders and keep records. Ladders with safety hazards should be controlled and prohibited from use until the hazards are eliminated. Ladders that have no repair value should be destroyed after appraisal by relevant personnel in the department. Safety officers have the obligation to stop violations of high-altitude operations.
Ladders should be placed in designated locations and locked (planned to be centrally placed, location to be determined). The herringbone ladder shall not be exposed to rain, sun, or barbecue, and shall not be placed in damp places. Ladders with safety hazards shall not be placed in positions where others may accidentally take them.
What is a retractable ladder
Herringbone ladder: a type of climbing tool used for decoration and other work in spaces above a flat surface (such as roofs). Due to its use, the front and rear ladder poles and the ground form an isosceles triangle, which looks like a "human" character, it is vividly called a "herringbone ladder". Practical zigzag ladders include fixed zigzag ladders and movable zigzag ladders. A fixed zigzag ladder is a temporary tool for people to build; The movable zigzag ladder is a type of ladder that connects the tops of two ladders together with loose leaves and can be closed when moving. Due to its flexibility, it is widely used in electrical operations. Early herringbone ladders were generally made of wood, and with the development of the metal industry, aluminum alloy materials were often used; Aluminum alloy herringbone ladders are widely used due to their lightweight, aesthetic, and durable characteristics, as well as their low cost.
