The difference between S1 and S1P safety shoes primarily lies in the inclusion of an anti-perforation system in S1P models, while both share core protective features like a safety toecap, antistatic properties, and energy-absorbing heels. These classifications fall under the EN ISO 20345 standard for safety footwear, which mandates higher protection levels than work shoes. Understanding these distinctions helps purchasers select footwear tailored to specific workplace hazards, such as puncture risks in construction or electrostatic discharge in manufacturing.
Key Points Explained:
-
Core Similarities Between S1 and S1P
Both types include:- A safety toecap (200-joule impact resistance per EN ISO 20345).
- Antistatic outsoles to dissipate electrical charges, reducing electrostatic discharge risks.
-
Energy-absorbing heels to minimize joint stress from repeated impacts.
These features make them suitable for dry industrial environments like warehouses or assembly lines.
-
Critical Difference: Anti-Penetration Sole (P)
- S1P adds a midsole anti-perforation layer (tested to withstand 1,100 Newtons of force) to protect against nails, glass shards, or sharp debris. This is absent in S1 shoes.
- Example use case: Construction sites or recycling facilities where ground hazards are prevalent.
- The 'P' suffix explicitly denotes this feature in the classification.
-
Material and Design Variations
- Both fall under Class I (leather or non-fully rubber/polymer construction), but materials vary:
- Toecaps: Steel, alloy, or composite options (e.g., lightweight titanium in alloy toes).
- Outsoles: Often incorporate slip resistant shoes technology for wet/oily surfaces, though S1/S1P are optimized for dry conditions.
- S2/S3 variants (not discussed here) include water resistance for wet environments.
- Both fall under Class I (leather or non-fully rubber/polymer construction), but materials vary:
-
Standards and Compliance
- EN ISO 20345 mandates stricter safety criteria than work shoes (EN ISO 20347), which lack toe protection.
- Testing includes:
- Toecap impact/crush resistance.
- Sole puncture resistance (for S1P).
- Electrostatic dissipation (resistance between 100 kΩ and 1,000 MΩ).
-
Purchasing Considerations
- Hazard assessment: Choose S1P if puncture risks exist (e.g., metalworking); S1 suffices for general manufacturing.
- Comfort: Both share similar ergonomic designs, but S1P may be marginally heavier due to the anti-penetration layer.
- Cost: S1P commands a ~10–20% premium over S1 due to added protection.
-
Industry Applications
- S1: Electronics assembly (static-sensitive areas), light machinery operations.
- S1P: Roofing, demolition, or any role involving sharp debris.
By evaluating workplace hazards and compliance needs, buyers can balance protection, comfort, and cost effectively. Would a composite toe (lighter but less conductive) better suit your team’s mobility requirements?
