Fatal Consequences of Choosing the Wrong Shoes

Alarming Statistics

I. Identification Differences: Recognizing Life-Saving Shoes at a Glance

Key Note: EH stands for Electrical Hazard and must include specific voltage rating (e.g., 6kV).

II. 6 Core Differences: Comprehensive Comparison from Resistance to Scenarios

1. Resistance Value: Slightly Conductive vs Absolutely Insulating

• Antistatic Shoes: 10⁶~10⁹Ω (Static Discharge Channel)
  ✅ Slowly dissipates static electricity to prevent sparks
  ❌ Cannot isolate high-voltage current

  
  

• Insulating Shoes: >10¹²Ω (Current Insulation Shield)
  ✅ Completely blocks current path
  ❌ Cannot eliminate static buildup

  
  

Testing Method: Use multimeter's 200MΩ range on sole. Antistatic shoes require regular testing (recommended every 3 months).

2. Material Formulation: Conductive Network vs Insulation Fortress

• Antistatic Shoes:

  
  
  

• Sole: PU/TPU + conductive carbon powder/metal fibers

• Upper: Conductive fiber blended fabric

• Structure: Embedded metal conductive grid (high-end models)

• Insulating Shoes:

  
  
  

• Sole: Pure rubber (thickness ≥4mm)

• Upper: Fully enclosed rubber/leather
  - taboo: No metal components (including eyelets)

3. Application Scenarios: ESD-Sensitive vs High-Voltage Hazard Areas

4. Protection Logic: Dissipation vs Isolation

• Antistatic Shoes: Acts like a grounding wire, channeling human static electricity to ground

• Insulating Shoes: Acts like an insulating bridge, blocking current path between human body and ground

Counterintuitive Fact: Antistatic shoes can protect against <250V shocks but never substitute for insulating shoes in high-voltage environments!

5. 搭配禁忌：生死组合

• Antistatic Shoes Forbidden:
  ❌Paired with insulated insoles/wool socks
• ❌Used on insulated ground

  
  

• Insulating Shoes Forbidden:
  ❌Use in humid environments (insulation performance decreases by 50%)
• ❌Continued use despite cracks on the sole of the shoe

  
  

6. Industry Standards: Testing Environment Determines Effectiveness

• Antistatic Shoes: Must be tested in 30%~85% humidity environment

• Insulating Shoes: Pass 6kV/1-minute voltage test (leakage current ≤1.8mA)

III. Three Steps to Choose the Right Life-Saving Shoes

1. Environment Diagnosis:

   
   
   

• Presence of ESD-sensitive components → Antistatic shoes

• Exposed high-voltage electricity → Insulating shoes

2. Mark Verification:
   Check tongue label: Antistatic shoes marked "A", insulating shoes marked "EH+voltage"

   
   

3. Golden Combinations:

   
   
   

4. 

• ESD environments: Antistatic shoes + ESD floor + grounding wristband

• High-voltage environments: Insulating shoes + insulating gloves + voltage tester

IV. Real Case Warnings

• Tragic Case: A chemical plant worker used wool insoles with antistatic shoes, causing static buildup and solvent vapor explosion

• Correct Practice: Electronics factory workers wearing antistatic shoes+clothing+bracelet increased product yield by 15%

Safety Maxim: "The cost of prevention is always lower than the price of an accident."
