Signage Classification and Color Management
Red signs indicate structural defects requiring thorough rectification before work can resume; yellow signs delineate maintenance areas, accessible only to certified personnel; green signs clearly indicate acceptance information, and high-risk scaffolding structures above 24 meters require three levels of signature and approval for acceptance, forming a color-coded risk management system.
Materials and Installation Specifications
PVC reflective material is used, tested for weather resistance from 20℃ to 60℃ and a 48-hour salt spray test; dual-point suspension at the main entrance and operating level, with the lower edge 1.5-1.7 meters from the ground, equipped with stainless steel expansion bolts to withstand level 8 winds; self-illuminating signs are installed in the nighttime work area, automatically illuminating for 8 hours when the light intensity is below 5 Lux.
Standardized Acceptance Management Process
A three-tiered acceptance system is implemented: For structures under 6 meters, the focus is on checking the verticality deviation of the uprights (≤H/200) and the height of the sweeping poles (≤200mm); for structures 6-24 meters, a pre-loading test at 1.5 times the design load is required; for structures over 24 meters, ultrasonic flaw detection is added, and the anchorage length of the cantilever frame embedded parts must be ≥25d, with parameter accuracy down to the millimeter level.
Dynamic Management Requirements
A "daily inspection + specialized inspection" mechanism is established, with stability assessments completed within 48 hours after a storm; structures exceeding the load limit by 20% are immediately downgraded, and change records are kept for two years after completion; RFID chips are piloted to achieve real-time traceability of acceptance data.
Safety Protection Collaborative System
The fall protection system requires two qualified anchor points per 30㎡, maintaining a horizontal lifeline tension of 5-8kN, and a vertical lifeline fall braking distance ≤0.6 meters, constructing a personnel-equipment integrated safety net.
Tool Fall Prevention
Tools weighing over 2kg must be secured with double ropes, with the thin ropes having a tensile strength ≥15kN; personnel passageways must be equipped with double-layer protective canopies, with an upper 50mm wooden board and a lower 18mm plywood board forming a 600mm spacing buffer layer.
