Safety shoes are protective gear specifically designed to shield feet from potential hazards in the workplace, widely used in industries such as construction, manufacturing, chemicals, mining, and logistics. The following details the definition, classification, standards, selection, and usage tips.

1. Core Function of Safety Shoes

• Anti-shatterThe toe cap is made of steel or composite material, designed to withstand impact from falling objects (typically meeting a 200 joule impact resistance standard).

• Stab-ResistantMidsole includes a stab-resistant layer (such as Kevlar material) to prevent sharp objects from piercing the sole.

• Anti-slipThe soles are designed with special patterns or rubber materials to enhance traction on smooth surfaces like oil and water stains.

• Anti-static/Electrically ConductiveDisperse static electricity through material conductivity to prevent sparks from causing explosions (suitable for flammable and explosive environments).

• InsulationIsolation of electrical current, protection for electricians and others working in environments with live electrical contact.

• Chemical-resistantSpecial coatings or materials resist erosion from acids, alkalis, and other chemicals.

• Insulation/Thermal ProtectionSuitable for high or low temperature working environments.

2. Classification Standards (e.g., Common Criteria)

• China Standard (GB)

• GB 21148-2020 "Foot Protection – Safety Footwear": Specifies performance requirements for anti-crushing, anti-piercing, and anti-static, etc.

• Label Example:GB 21148-2020 An1Anti-smash and anti-pierce.

• European Standard (EN ISO)

• EN ISO 20345 (General Safety Footwear), EN ISO 20347 (Occupational Safety Footwear): Detailed SB/S1/S2/S3 classifications (with additional features like waterproof and oil-resistant).

3. Key Selection Points

• Suitable for work environment：

• Construction Site: Priority for anti-blow, anti-pierce, and anti-slip.

• Chemical/Electronics Factory: Requires anti-static or insulating properties.

• Metallurgy/Welding: Select models with high-temperature resistance or metal spatter prevention.

• Size and Comfort：

• One and a half sizes larger than regular shoes (requires thick socks), ensuring ample toe room.

• Check for a snug fit at the toe and ensure the insole conforms to the arch of the foot during try-ons.

• Certification Mark：

• Regular products should have the LA safety mark (China) or CE certification (EU).

• Brand & Material：

• Prefer well-known protective brands (such as Honeywell, Delta, etc.).

• Upper material (leather, synthetic) affects breathability and durability.

4. Usage and Maintenance

• Regular inspections：

• Toe and sole integrity, and whether the puncture-resistant layer is damaged.

• Insulating shoes must be tested for electrical properties every 6 months.

• Cleaning and Maintenance：

• Wipe with a damp cloth; avoid corrosion from chemical solvents.

• Avoid high-temperature drying to prevent material aging.

• Replacement Cycle：

• Recommended for replacement every 6-12 months with frequent use (such as 8 hours per day).

5. Important Notes

• Disable in non-protective scenariosDaily wear can affect comfort, and some features (such as static dissipation) require the use of conductive flooring.

• Special Environment CompatibilitySelect specific styles (such as cold-resistant boots, high-temperature boots) for extreme cold or hot environments.
