Introduction
Standard Framework and Core Elements
| Element Category | Key Requirements | Implementation Points |
|---|---|---|
| Risk Prevention | 4.2.2 Identification and Assessment Methods | Establish a basic risk database and adopt a dynamic identification mechanism |
| Equipment Management | 4.4.2 Equipment System | Formulate 18 quality control standards and implement status evaluation |
| Process Control | 4.5.3 Operation Management | 7 major operation system procedures + 5 types of technical standards |
Risk prevention and control implementation strategy
The standard requires the establishment of a three-dimensional risk control system:
- Basic identification: Comprehensive assessment of equipment systems using methods such as JSA and HAZOP
- Dynamic control: Change management (4.2.5) and pre-operation re-identification mechanism
- Special plan: Including five types of special control such as occupational health (4.2.3.4) and environmental protection (4.2.3.5)
Typical application: Boiler anti-wear and explosion prevention management
A power plant achieved the following through metal supervision + condition maintenance (4.5.5.4):
- Establish a boiler tube wall thickness monitoring database
- Reduce the risk level of pipe burst from Class A to Class C
Equipment life cycle management
The standard innovatively proposes four-dimensional quality control:
| Phase | Key control points | Corresponding clauses |
|---|---|---|
| Construction period | Completion drawing specifications (4.4.1.2c) | 4.5.2.1 |
| Operation period | 18 technical standards (4.4.2.1) | 4.5.3 |
| Maintenance period | Condition-based maintenance strategy (4.5.5.4) | DL/T 838 |
| Retirement period | Deregistration of special equipment (4.4.8.2d) | 4.4.6 |
Innovation of supervision and evaluation mechanism
Standard construction of a double closed-loop supervision system:
1) Execution layer closed loop: Daily supervision is achieved through violation management (4.6.3) + hidden danger control (4.6.4)
2) System layer closed loop: System improvement is achieved through annual review (4.6.7) + third-party audit (4.6.6)
A certain group application case shows that this mechanism has reduced the annual non-conformity of the system by 37%
Implementation suggestions
- Step-by-step construction path:
- Phase I: Complete the construction of 4.2 risk database (6 months)
- Phase II: Implement 4.5.5 status maintenance (12 months)
- Informatization tools: It is recommended to build a supporting safety production information system (4.1.5.3)
- Cultural cultivation: Establish behavioral norms through 4.1.3 concept and culture clauses
