What are the requirements for EN ISO 20345 compliant safety shoes? Essential Standards for Workplace Safety

EN ISO 20345 compliant safety shoes must meet specific requirements to ensure worker protection across various hazardous environments. The standard mandates a 200-joule impact resistance at the front, anti-slip soles for greasy/smooth surfaces, and a closed back. Additional protections are categorized (e.g., A for anti-static, Fo for hydrocarbon resistance) and classified into levels (SB to S5) based on risk exposure. These shoes are rigorously tested for durability, puncture resistance, water ingress prevention, and energy absorption to adapt to industrial needs.

Key Points Explained:

  1. Core Protection Requirements

    • 200-joule toe impact resistance: The front cap must withstand impacts equivalent to dropping a 20kg weight from 1m height.
    • Anti-slip soles: Designed for stability on greasy, wet, or smooth surfaces (tested per ISO 13287).
    • Closed back: Prevents debris entry and ensures foot enclosure.
  2. Specialized Protection Categories

    • A (Anti-static): Dissipates electrostatic charges (<1000V resistance) for electronics or explosive environments.
    • Fo (Hydrocarbon-resistant soles): Resists degradation from oils/fuels (e.g., safe shoe for mechanics).
    • E (Energy absorption): Heel/sole cushions reduce fatigue (tested for 20J compression energy).
    • P (Puncture-resistant): Midsole blocks sharp objects (tested to 1100N force).
    • Wru/Wr (Water resistance): Wru prevents upper penetration, while Wr offers full waterproofing (tested under 15cm submersion).
  3. Classification Levels (SB to S5)

    • SB (Basic): Meets only core requirements (impact/slip/closed back).
    • S1: Adds anti-static, heel energy absorption, and fuel resistance.
    • S2: Extends S1 with water penetration resistance (Wru).
    • S3: Includes S2 + puncture resistance (P) and cleated soles.
    • S4/S5: Covers waterproof (Wr) and full chemical/mechanical protections (e.g., rubber boots).
  4. Testing and Certification

    • Shoes undergo lab tests (e.g., toe compression, slip angle, hydrolysis) and field trials.
    • Compliance is marked with "EN ISO 20345" and category codes (e.g., "S1P" for puncture-resistant S1).
  5. Selection for Work Environments

    • Construction (S3): Prioritizes puncture/water resistance.
    • Oil rigs (S1 Fo): Focuses on fuel/oil slip resistance.
    • Electrical work (A-rated): Requires anti-static properties.

Did you know? Over 60% of workplace foot injuries occur due to inadequate footwear—highlighting why EN ISO 20345’s granular standards are vital for risk-specific industries.
