Proper use of ladders

How to use the ladder correctly?

Safety production is a necessary guarantee for the survival of an enterprise!

The ladder is often used in our usual work and life. However, in the work, there will be some error use and misunderstanding. There are certain safety hazards. Now the safety precautions of the ladder will explain one by one in use. Hidden safety hazards such as injuries, do your own protection!

  1. Classification of ladders

There are many types and forms of ladders. Materials also have a variety of bamboo, wood, steel, and alloy. Its structural structure has national standards. Most of us use aluminum alloy ladders in our work, which are more secure than other materials in terms of firmness, durability, insulation and other aspects.

Proper use of ladders

  1. Check before use

First check whether there are screw looseness in the ladder; whether the pedal and the foot of the ladder foot are loosened and falling off; whether the safety lock is flexible; whether the ladder’s feet non-slip glue pads are intact and cracks; the zipper remains intact and the length is appropriate.

  1. The functions and maximum load and opening perspectives of the components of the ladder
  2. Security lock:
  3. Control and fix the opening and closing angle of the human character ladder b. The folding ladder can be changed to a word ladder and firmly connected and fixed.
  4. Anti-slip glue pad:
  5. Prevent the side of the ladder foot slip b. Insulation

C: The opening and closing angle on the top of the human character ladder is 35 ° -45 °, and the opening distance of the ladder is not greater than 1/2 of the length of the ladder; It is more than 1/4 of the ladder, which is easy to slip, which is dangerous. The upper and lower spacing of the pedal should be 300mm, and there must be no stalls.

D: The structure of any high -logging tool must be firm and reliable. For the upper and lower pedals for operators, the load should not be greater than 110 kg. When there are special homework on the ladder surface, the weight that is pressed on the pedal may exceed the above load value, and other methods should be taken in other ways (moving scaffolding, inverted chain, etc.)

  1. How to use

When you use any ladder up and down, you must face the ladder, and you are not allowed to hold any utensils in your hands; you are not allowed to stand on the highest level of the ladder for operation; when you stand on the second floor operation, you need to step on the ladder on both sides of the ladder on both sides of the ladder. , And there are special persons in monitoring; when the word ladder is operated by the wall, a special person must be monitored and measured to prevent the side of the ladder from slipping. There are many types of mobile ladders, and the number of times is more frequent. It is often used freely without inspecting. Therefore, in addition to the new ladder, before use, the quality acceptance must be performed in accordance with the current national standards, and it is necessary to conduct regular inspections and maintenance.

  • What are the common water hose materials and characteristics ?  

    What are the common water hose materials and characteristics ? Here is the relevant content introduction for reference. The cast-iron hoses: strong corrosion resistance, crispy texture, poor impact resistance and seismic resistance, and large weight. Steel hoses: high pressure resistance, vibration resistance, light weight, large length of the single tube and convenient interface, but poor stability, poor corrosion resistance, anti-corrosion measures inside and outside the tube wall, high cost. Pre-stress and self-stress reinforced concrete tubes: pre-stress reinforced concrete tube cost low, strong seismic performance, smooth tube wall, good hydraulic conditions, corrosion resistance, low explosion tube rate. The price of concrete tubes is cheaper than steel hoses, and the interface is socket type. Glass reinforced plastic hoses: corrosion resistance, no scaling, can maintain high water transmission capacity for a long time, high strength, low rough coefficient, but high price. Plastic tubes: high strength, smooth surface, not easy to scaling, small head loss, corrosion resistance, light weight, convenient processing and interface, etc., but the strength of the hose is low, the expansion coefficient is large. When used as a long distance hose,you need…

  • Introduction of water hoses of various materials

    Introduction of water hoses of various materials Product introduction: PP-R hose PP-R hose, also known as type III polypropylene hose, is non-toxic, light, pressure resistant, corrosion resistant, and has good impact resistance and long-term creep performance. It is mainly used in water supply hoseline system and can be used in pure drinking water hoseline. PP-R hose is divided into cold water hose and hot water hose. The interface of PPR hose adopts the hot-melt technology, and the hoses are fully integrated together. Therefore, once the installation pressure test is passed, the aging and water leakage phenomenon will not occur for a long time like the aluminum-plastic hose, and the reliability is very high. PPR hose has no scaling, good heat preservation performance and smooth hose wall. It is becoming a promotional material. However, the high temperature resistance of PPR hose is slightly poor, and the long-term working temperature shall not exceed 70 ℃; And bending construction is not allowed. In terms of comprehensive performance, PPR hose is the hose with high cost performance at present, so it has become the…
