To be precise, the EN ISO 20345:2022 standard for safety footwear introduced two new optional performance features: SC for scuff cap abrasion resistance and LG for ladder grip. Concurrently, it reclassified fuel oil resistance (FO) from a mandatory requirement for S1-S5 level footwear to an optional one, reflecting a significant shift in the standard's philosophy.
The core change in EN ISO 20345:2022 is a move from broad, generalized safety categories to a more modular and specific approach. This empowers safety professionals to select footwear based on the precise, real-world risks of a particular job role, rather than relying on a one-size-fits-all classification.
A Deeper Look at the New Optional Markings
The 2022 update allows for more granular testing to verify a boot's suitability for specific tasks. This is a direct response to a need for footwear that not only protects but also performs reliably in specialized environments.
SC: Scuff Cap Abrasion Resistance
A "scuff cap" is a covering over the safety toecap area. The SC marking indicates that this covering has passed a rigorous abrasion test.
This is a critical feature for roles involving frequent kneeling or crawling, such as flooring installation or automotive repair. It ensures the longevity and integrity of the boot's structure, preventing premature wear and tear.
LG: Ladder Grip
The LG marking certifies that the outsole has a specific design in the heel and arch area to provide secure footing on ladder rungs.
This feature directly enhances safety for anyone working at height, including construction workers, electricians, and warehouse operatives. It provides an extra layer of stability in a high-risk activity.
The Reclassification of Fuel Oil Resistance (FO)
One of the most significant changes was making fuel oil (FO) resistance an optional feature rather than a default requirement for most safety classes.
From Mandatory to Optional
Previously, resistance to fuel oil was a standard feature of footwear marked S1 and above. Under the 2022 standard, if this protection is required, it must be specifically requested and will be indicated by the FO marking.
Why the Change?
This change acknowledges that exposure to fuel oil is not a universal workplace hazard. By making it optional, manufacturers can use a wider range of outsole materials that may offer superior performance in other areas, such as slip resistance or flexibility, without being constrained by the need for oil resistance.
Understanding the New Waterproof Categories: S6 & S7
While not optional features in the same way as LG or SC, the new S6 and S7 categories represent a higher, optional tier of waterproof performance that is new to the standard.
Beyond Water Resistance (WR)
The previous WR (Water Resistance) marking only tested for limited water penetration of the upper. The new S6 and S7 classifications test the entire footwear for waterproofness, typically indicated by the WPA (Water Penetration and Absorption) marking.
Defining S6 and S7
These new categories build upon the familiar S2 and S3 classifications by integrating this guaranteed level of waterproofness.
- S6: Includes all S2 requirements (toecap, closed heel, antistatic, energy absorption) plus WPA waterproofness.
- S7: Includes all S3 requirements (the same as S2 plus midsole penetration resistance and a cleated outsole) plus WPA waterproofness.
Understanding the Trade-offs
The new standard's modularity introduces a critical need for careful consideration during procurement. Simply asking for an "S3 boot" is no longer sufficient.
Specialization vs. Generalization
The key trade-off is between a highly specialized boot and a general-purpose one. A boot with excellent ladder grip (LG) might use an outsole compound that doesn't offer fuel oil resistance (FO). The new standard forces a choice based on the primary hazards.
The Importance of Risk Assessment
This shift places a greater responsibility on the end-user or safety manager. A thorough, role-specific risk assessment is now essential to identify the exact combination of features required. Assuming a feature is included by default can lead to a critical gap in protection.
How to Specify Footwear Under EN ISO 20345:2022
Use your risk assessment to build a clear specification for the footwear you need.
- If your primary focus is durability for high-wear roles (e.g., flooring installers): Specify footwear with the SC marking to ensure the toecap area withstands abrasion.
- If your primary focus is safety for working at height (e.g., construction, utilities): Mandate footwear with the LG marking for proven stability on ladders.
- If your primary focus is consistent work in wet conditions (e.g., groundworks, agriculture): Look for footwear certified to the new S6 or S7 categories for guaranteed waterproof performance.
- If your primary focus is environments with hydrocarbon risk (e.g., garages, petrochemical): You must now explicitly request the FO marking to ensure outsole resistance.
This updated standard empowers you to make more precise and effective safety decisions for your team.
Summary Table:
| Feature | What It Means | Key Benefit |
|---|---|---|
| SC (Scuff Cap) | Enhanced abrasion resistance over the toecap. | Increases boot longevity for kneeling/crawling tasks. |
| LG (Ladder Grip) | Certified outsole grip for ladder rungs. | Improves stability and safety for work at height. |
| FO (Fuel Oil) | Now an optional, not mandatory, feature. | Allows for more specialized outsole material choices. |
| S6 / S7 | New categories with guaranteed waterproofness (WPA). | Provides superior protection for consistently wet environments. |
