After 2005, China transitioned from being a net importer of scaffolding to a net exporter, marking a significant shift in the global scaffolding market. During this period, the world's scaffolding production capacity grew by 1.91%, outpacing the growth in output, which was only 0.87%. This led to an increasing imbalance between supply and demand, creating a growing surplus in the market.
To ensure safety and efficiency in scaffolding operations, several key regulations must be strictly followed:
1. All scaffolding erection, maintenance, and dismantling work must be carried out at heights of 2 meters or above. It is crucial to adhere to all high-altitude safety protocols to prevent accidents.
2. Workers involved in scaffolding tasks must have proper training and hold valid certifications. They should be well-versed in the technical aspects of scaffolding construction and safety procedures.
3. Whenever possible, scaffolding work should be avoided during nighttime hours. If night operations are necessary, the site must be adequately illuminated, and the height of the scaffolding should not exceed the second-highest level (below 15 meters) to maintain safe working conditions.
4. For large-scale scaffolds, suspended scaffolds, or those exceeding 25 meters in length, a designated responsible person must oversee the project. Each scaffold should have a dedicated inspector for regular checks and maintenance to prevent damage or unauthorized tampering.
5. Scaffolding work must be halted when wind speeds reach six levels or higher, or during heavy rain, snow, or fog. These weather conditions significantly increase the risk of accidents.
6. When erecting or dismantling scaffolding, barriers and warning signs should be placed on the ground. A dedicated guard should be assigned to prevent unauthorized personnel from entering the area.
7. Excavation activities must not be conducted near the foundation of any scaffolding structure, as this can compromise its stability and safety.
8. All workers on scaffolding must wear safety helmets, fasten their harnesses, and wear non-slip footwear. The consumption of alcohol is strictly prohibited while working on scaffolds.
9. Safety signs and signal flags or lights should be installed on the exterior and top of scaffolds to prevent collisions with passing vehicles and cranes. This helps enhance visibility and reduce the risk of accidents.
10. When using ladders or other equipment during multi-device construction, appropriate measures must be taken to secure them, and a supervisor should be present to ensure safe operation.
These guidelines are essential for maintaining a safe and efficient scaffolding environment, reducing risks, and ensuring compliance with industry standards. By following these rules, construction sites can minimize hazards and promote a culture of safety among workers.
Electric Gate Valve
An electric Gate Valve is a type of valve that uses an Electric Actuator to open and close the gate of the valve. The gate is a flat or wedge-shaped piece that moves perpendicular to the flow of the fluid. When the valve is open, the gate is lifted or pushed aside to allow the fluid to pass through. When the valve is closed, the gate is lowered or pressed against the valve seat to prevent the fluid from flowing.
Electric gate valves are commonly used in industrial applications where precise control of the fluid flow is required. They are often used in pipelines, water treatment plants, oil and gas refineries, and chemical processing plants. The electric actuator allows for remote control of the valve, which can be operated from a control room or a computerized system. This makes it easier to monitor and adjust the flow of the fluid, which can improve efficiency and reduce the risk of leaks or spills.
