When company leaders or safety officers search for “fall protection systems,” “fall protection equipment inspection,” or “work-at-height safety management,” what they truly want to know is not theoretical concepts but answers to three questions:
Is the current practice compliant with regulations?
If an accident occurs, is the system truly reliable?
How should a fall protection system be established so that it is implementable, auditable, and sustainable?
At many high-rise construction sites, the following scenario is still commonly observed: workers wear safety harnesses, attach the hook to a steel component or scaffolding member, and then assume the task is “safely completed.”
In reality, this is merely the beginning, not the end.
A truly reliable fall protection system must be based on engineering mechanics calculations, certified anchorage points, lifeline system design, and continuous inspection and management—not merely the simple combination of individual pieces of equipment.
1. Fall Impact: Anchor Points Do Not Bear “Body Weight”
Many people underestimate the impact force generated during a fall. An 80 kg worker falling from a height of 2 meters can generate instantaneous impact forces reaching several thousand newtons.
The key point is that an anchor point withstands dynamic impact loads, not the static body weight of a person.
If an energy absorber is absent or insufficient deployment space is available, the impact force will be directly transmitted to:
The anchorage structure
The harness connection components
The worker’s body
This is why anchorage design must be based on engineering calculations rather than experience-based assumptions.
Suspension Trauma and Rescue Response
Even when a fall is successfully arrested, the following risks may still occur:
Rebound impact
Back D-ring collision hazards
Suspension trauma
Therefore, a fall protection system must include rescue plans and drill mechanisms, rather than focusing solely on equipment configuration.
2. Anchorage Point Design: The Lifeline of the System
Standard Requirements
According to GB 30862:2014 and EN 795:2012, fall protection anchorage devices must meet specified dynamic load testing requirements.
In practical engineering design, approximately 15 kN per person is commonly used as a reference design value.
However, common issues observed on construction sites include:
Hooks attached directly to reinforcing bars
Connections made to scaffold components without structural verification
Absence of pull-out test reports
Lack of anchor point numbering and identification
Correct practices include:
Structural engineers participating in anchorage verification calculations
Conducting pull-out tests
Establishing an anchor point registry and management system
Clearly distinguishing between permanent anchor points and temporary anchor points
3. Lifeline Systems: Enabling Continuous Protection
Single-point anchorage cannot meet the requirements of tasks involving continuous movement. Modern high-rise construction must therefore incorporate lifeline systems.
3.1 Vertical Lifeline Systems
Applicable for:
Core tube construction
Tower crane climbing operations
Elevator shaft work
Key design considerations:
Control of wire rope tension
Reliable locking performance of fall arresters
Regular inspection for wear and damage
3.2 Horizontal Lifeline Systems
Applicable for:
Roof construction
Steel structure installation
Edge work involving lateral movement
The core design considerations include:
Free fall distance calculation
Energy absorber deployment length
Rope sag
Required safety clearance
A lifeline system designed without proper clearance calculations may ultimately fail to provide real protection.
4. Inspection of Fall Protection Equipment: Frequently Overlooked
Many organizations focus only on purchasing equipment while neglecting subsequent inspection and maintenance.
Compliant management should include:
Visual inspection before each use
Professional inspection at least once per year
Establishment of inspection records and documentation
Webbing wear, connector deformation, and abnormal energy absorber conditions can all lead to system failure.
Safety is not a one-time procurement—it is a process of continuous management.
