Level 1: Necessity Assessment (0→20 Points)
Evaluate whether the work genuinely requires elevation
Identify alternatives (prefabricated components, ground-level assembly, mechanical lifts)
Document the assessment process (aligned with GB/T 28001 Occupational Health and Safety Management Systems)
Level 2: Three-Dimensional Risk Identification (20→40 Points)
Environmental/Structural Layer
Equipment/Tool Layer
Personnel/Management Layer (The Decisive Factor)
Uncertified workers, inadequate training
Medical contraindications (acrophobia, hypertension, heart disease)
Fatigue, risk-taking behavior
Poor enforcement of policies
Reference GB/T 13861 (Classification and Coding of Hazardous and Harmful Factors in Production)
Build a corporate "Risk Identification Library" and check each project against it systematically
Use this library as the standard tool during monthly inspections
Initial Screening: Medical exams to exclude contraindications; training and certification (per JGJ 80 requirements)
Annual Refresher: Regulatory updates, incident case studies, hands-on drills
Individual Records: Training logs, medical results, work history, violation records
Level 3: Risk Scoring & Classification (40→60 Points)
Risk Level | Response Strategy | Example |
High | Immediate shutdown, mandatory control or elimination | 15-meter scaffolding without safety nets |
Medium | Specialized plan with monitored execution | Worker with acrophobia assigned to height work → reassign or retrain |
Low | Routine supervision, periodic review | 2-meter window replacement, certified worker, good weather |
Procurement: Select only GB/T 5725-certified products
Site Intake: Comprehensive inspection, photographic documentation, numbering
Daily Use: Pre-shift visual inspections
Periodic Testing: Technical inspection every 6-12 months
Annual Certification: Engage qualified inspection agencies
Post-Incident: Immediate suspension, re-inspection required before reuse
Level 4: Hierarchical Controls (60→80 Points)
Elimination: Cancel the high-altitude work (Level 1 outcome)
Substitution: Replace high-risk methods with lower-risk alternatives
Engineering Controls: Safety nets, guardrails, fall arrest systems (hardware)
Administrative Controls: Standard operating procedures, permit systems, inspection schedules (processes)
PPE (Personal Protective Equipment): Safety harnesses, helmets, non-slip footwear (last line of defense)
Level 5: Documentation & Review (80→100 Points)
Risk assessment reports
Control measure inventories
Complete equipment inspection records
Personnel training and medical files
Monthly/quarterly inspection logs
Incident reports and corrective actions
Pre-project: Comprehensive risk assessment
Monthly: Equipment checks and site inspections
Semi-annually: Periodic equipment certification
Annually: Safety system review, policy updates
6-Month Implementation Roadmap
Conduct systematic risk identification (three-dimensional framework)
Audit gaps in equipment, personnel, and policies
Develop/revise "High-Altitude Work Safety Procedures"
Create risk matrix and classify all hazards
Procure and inspect equipment in bulk
Build electronic archive system (Excel acceptable)
Conduct organization-wide training, certification, and medical screening
Establish monthly/annual inspection schedules
Execute inspection protocols
Track KPIs: incident rate, violation frequency, corrective action response time
Quarterly dynamic risk reassessment
Annual system audit
What Mastery Actually Means
Dimension | Zero State | Mastery State |
Costs | Reactive payouts and penalties | Proactive investment and insurance |
Execution | After-the-fact remediation | Prevention-first approach |
Traceability | Vague | Fully auditable |
Culture | Safety as burden | Safety as competitive advantage |
