With the update to the EN ISO 20345:2022 safety shoe standard, the S7 protection class is garnering increasing attention. For procurement professionals in sectors such as construction, mining, logistics, manufacturing, and outdoor engineering, understanding the differences between S3 and S7 helps in selecting the most appropriate protective footwear for specific work environments.
Cuáles son Zapatos de seguridad S3?
S3 safety shoes are widely used in the industrial sector. Under the EN ISO 20345 standard, the S3 rating typically includes the following protective features: impact protection (200J impact-resistant toe cap); compression protection (15kN compression-resistant toe cap); puncture-resistant midsole; antistatic properties (A); heel energy absorption (E); water-resistant upper (WRU); and slip-resistant outsole.
S3 shoes are suitable for most industrial work environments, such as factory production floors, warehouse and logistics areas, general construction sites, equipment installation and maintenance, and semi-outdoor work environments.
The uppers of S3 safety shoes are typically made of water-resistant treated leather or synthetic materials, capable of withstanding water droplets, mud, and brief exposure to wet conditions encountered during daily work.
However, it is important to note that S3 does not equate to being fully waterproof. In environments with standing water for extended periods, moisture may still penetrate the shoe through the upper, seams, or structural joints.
Cuáles son Zapatos de seguridad S7?
S7 is a significant new protection class introduced in the EN ISO 20345:2022 standard. It builds upon the S3 specifications by adding full waterproof protection. Many S7 safety shoes utilize waterproof-breathable membranes, waterproof bootie constructions, or multi-layer composite uppers to create a “waterproof barrier.” This design not only prevents external moisture from entering but also facilitates the escape of internal moisture, enhancing comfort during prolonged wear.
Consequently, S7 shoes are better suited for: construction during rainy seasons, mining operations, el oil and gas industry, outdoor engineering projects, port and terminal operations, and environments characterized by prolonged wetness.
For workers requiring all-weather performance, S7 safety shoes effectively mitigate the discomfort and health risks associated with prolonged foot exposure to moisture.
What are the differences between S3 and S7 safety shoes? In short: S3 is akin to an all-round industrial safety shoe, whereas S7 is more like a specialized waterproof safety boot designed for harsh weather and wet environments.
