Major Updates in EN ISO 20345
The transition from EN ISO 20345:2011 to the 2022 version brings several significant modifications that safety managers, procurement specialists, and workers should understand. These updates reflect a decade of research and industry feedback aimed at addressing gaps in the previous standard.
Revised Testing Methodologies
One of the most substantial changes in Safety Standards EN ISO 20345:2022 involves the testing protocols used to evaluate footwear performance. The updated standard introduces more rigorous and realistic testing scenarios that better simulate actual workplace conditions:
Impact resistance testing: The new standard modifies the test for toecap protection, requiring footwear to withstand impacts that more accurately reflect real-world hazards. The test energy levels remain at 200J, but the methodology has been refined to ensure consistent results across testing facilities.
Compression testing: Updated compression tests evaluate how toecaps perform under sustained pressure, with modifications to ensure footwear maintains its protective capabilities throughout its service life.
Penetration resistance: The testing for penetration resistance has been significantly enhanced, with new protocols that assess protection against smaller diameter nails and sharp objects, addressing a common workplace hazard that previous standards didn't fully account for.
Electrical properties testing: The 2022 standard includes updated methods for testing electrical resistance properties, ensuring footwear labeled as electrically resistant or conductive truly performs as expected in workplace environments.
Chemical resistance: New testing protocols evaluate how footwear materials withstand exposure to common industrial chemicals, with more comprehensive assessment of degradation over time.
These revised methodologies ensure that safety footwear certified under EN ISO 20345:2022 provides more reliable protection in real-world conditions, addressing limitations identified in the previous standard's testing approach.
Enhanced Protection Requirements
Safety Standards EN ISO 20345:2022 raises the bar for protective performance across several critical areas:
Improved toecap protection: While maintaining the 200J impact resistance requirement, the standard now includes more specific criteria for toecap design and integration, ensuring better protection against both impact and compression hazards.
Enhanced puncture resistance: The new standard addresses the growing concern about puncture injuries from smaller diameter objects by requiring improved midsole protection that can resist penetration from thinner, sharper items.
Heat and flame resistance: Updated requirements for heat resistance include more stringent testing for footwear intended for use in high-temperature environments, with specific attention to sole adhesion and material integrity when exposed to heat.
Water resistance: The 2022 standard introduces more comprehensive water resistance testing, ensuring footwear labeled as water-resistant or waterproof maintains these properties throughout normal use.
Ergonomic considerations: For the first time, the standard incorporates requirements related to ergonomic design, recognizing that safety footwear must balance protection with comfort and usability to ensure workers actually wear their protective equipment.
New Slip Resistance Classifications
Perhaps the most notable change in Safety Standards EN ISO 20345:2022 is the complete overhaul of slip resistance testing and classification. Slips, trips, and falls remain among the most common workplace accidents, and the new standard addresses this hazard with significantly improved testing methods:
New SR classification system: The previous SRA, SRB, and SRC classifications have been replaced with a new SR (Slip Resistance) classification that uses a single test method on multiple surfaces.
More realistic testing surfaces: The new standard uses test surfaces that better represent real-world conditions, including contaminated floors and varying surface textures.
Dynamic testing: Rather than just measuring static friction, the new tests incorporate dynamic movement that better simulates actual walking motions and slip incidents.
Clearer performance requirements: The standard establishes more precise minimum performance thresholds for slip resistance, making it easier for purchasers to select appropriate footwear for specific environments.
This revised approach to slip resistance provides a more reliable indication of how safety footwear will perform in preventing slips and falls in actual workplace settings, addressing a significant limitation of the previous standard.
Practical Implications for Workwear Selection
The introduction of Safety Standards EN ISO 20345:2022 has several important implications for organizations and individuals responsible for selecting and purchasing safety footwear:
Reevaluation of existing inventory: Safety managers should review their current footwear inventory against the new standard to identify potential gaps in protection.
Updated procurement specifications: Organizations need to update their procurement requirements to specify compliance with the 2022 standard rather than previous versions.
Training and awareness: Workers and supervisors require education about the new standard and how it affects their safety footwear selection and use.
Transition planning: Companies should develop a transition plan to gradually replace older footwear with models certified to the new standard, prioritizing high-risk areas.
Documentation updates: Safety policies, risk assessments, and personal protective equipment (PPE) documentation need updating to reflect the new standard's requirements.
The transition to the new standard may involve additional costs as manufacturers update their designs and certification processes, potentially leading to price increases for compliant footwear. However, these costs should be weighed against the improved protection and potential reduction in workplace injuries.
Industry-Specific Compliance Considerations
Different industries face unique challenges in adapting to Safety Standards EN ISO 20345:2022:
Construction: The enhanced puncture resistance requirements are particularly relevant for construction workers regularly exposed to sharp objects and uneven surfaces. Construction companies should prioritize footwear with improved penetration protection.
Manufacturing: The updated electrical resistance testing is crucial for manufacturing environments where static electricity poses risks. Facilities should verify that footwear meets the specific electrical properties needed for their operations.
Food processing: The new slip resistance classifications are especially important in food processing facilities where wet and contaminated floors are common. These operations should focus on footwear with high SR ratings.
Chemical processing: The enhanced chemical resistance testing in the new standard helps ensure better protection in chemical handling environments. Companies should select footwear specifically tested against the chemicals present in their facilities.
Logistics and warehousing: The ergonomic considerations in the new standard are particularly beneficial for workers who walk or stand for extended periods. Warehouse operations should balance protection with comfort features to encourage consistent PPE use.
Organizations should conduct industry-specific risk assessments to determine which aspects of the new standard are most relevant to their operations and prioritize those features when selecting safety footwear.
