I. Function Introduction

Risk area management achieves the following by identifying and classifying risks in production sites and dividing them into spatial ranges with specific risk levels:

• Risk Visualization: Four-color labeling to intuitively display risk distribution
• Grid Management: Dividing areas into manageable units
• Precision Control: Implementing differentiated measures for different risk levels
• Dynamic Monitoring: Real-time updates of risk status changes

Core Value:

• Enhance risk perception capabilities
• Optimize resource allocation
• Strengthen control of key areas
• Support emergency decision-making

Legal Basis:

• 《General Rules for Safety Production Risk Classification and Control System》(GB/T 33000)
• 《Basic Norms for Enterprise Safety Production Standardization》(GB/T 33000)

Access Entry:

1. Administrator logs into management backend
2. Navigation menu select: 【Risk Identification】→【Risk Areas】

II. Add Risk Area

Operation Steps:

1. Click "New" button on toolbar

2. Fill in key information:

   • Area Name (Required, e.g. "Production Workshop 1")
   • Category (Classification management)
   • Remarks (Area description)

3. Click "Save" to complete creation

Precautions:

• Area names must be unique and non-repeatable
• Recommended to draw area boundary diagrams

III. Modify Risk Area

Operation Steps:

1. Locate target area
2. Click edit button in operation column
3. Modify:
   • Area Name (Required, e.g. "Production Workshop 1")
   • Category (Classification management)
   • Remarks (Area description)
4. Click "Save" to submit

IV. Delete Risk Area

Operation Steps:

1. Locate target area
2. Click delete button in operation column
3. Confirm deletion operation

Deletion Restrictions:

• Areas with risk points cannot be deleted
• Areas with historical inspection records cannot be deleted

V. Risk Four-color Map Management

1. Function Description

The risk four-color map is a core tool for risk visualization:

• Level Identification: Red/Orange/Yellow/Blue four-color labeling for risk levels
• Grid Management: Dividing areas into manageable units
• Dynamic Updates: Real-time reflection of risk status changes

Level Standards:

Color	Risk Level	Control Requirements
Red	Major Risk	Immediate rectification, real-time monitoring
Orange	High Risk	Rectification within time limit, key monitoring
Yellow	Medium Risk	Routine control, regular inspection
Blue	Low Risk	Daily monitoring, self-management

2. Four-color Map Editor

Access Path:

1. Locate target area
2. Click "Design" button in operation column
   

3. Operation Guide

Function	Operation Steps	Icon	Requirements
Insert Base Map	1. Click "Insert" > "Insert Image" 2. Select plant layout/aerial photo		Resolution ≥300dpi
Draw Risk Unit	1. Select polygon tool 2. Click to draw closed area 3. Set properties: - Name - Risk Level		Unit area ≤500㎡
Add Risk Point	1. Select risk point icon 2. Drag to accurate position 3. Set properties: - Code - Name - Risk Level		Code must be unique
Direction Indicator	1. Select direction icon 2. Place in corner of drawing		Label "North-South Orientation"
Add Legend	1. Select legend icon 2. Place in suitable position 3. Edit legend content		Include four-color level description
Delete Element	Right-click target element and select "Delete"		Confirm before deletion

4. Design Standards

1. Base Map Requirements:
   • Use latest plant layout
   • Scale 1:500-1:1000
   • Include main reference objects
2. Unit Division:
   • Divide grids by functional area
   • Single grid ≤500㎡
   • Clear boundaries without overlap
3. Labeling Standards:
   • Unique risk point codes
   • Use unified legend symbols
   • Mark evacuation routes

VI. Best Practices

1. Design Principles

• Risk-Oriented: Highlight key high-risk areas
• Practicality First: Ensure on-site recognizability
• Dynamic Updates: Quarterly risk status updates
• Full Participation: Train employees in map reading

2. Application Scenarios

Scenario	Application Method	Effect
Daily Inspection	Plan routes according to four-color map	Prioritize inspection of high-risk areas
Emergency Response	Quickly locate risk points	Shorten emergency response time
Safety Training	Visual risk education	Improve risk awareness
Contractor Management	Mark dangerous operation areas	Strengthen external personnel control
