Safety shoes are protective gear specifically designed to shield the 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 tips, and usage points.
1. Core Function of Safety Shoes
Impact-resistantThe shoe toe is equipped with a steel cap or composite material, designed to withstand impacts from falling objects (typically meeting a 200 joule impact resistance standard).
Stab-ResistantThe insole is reinforced with 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).
InsulationIsolate electrical currents to protect electricians and others working in environments with live electrical contacts.
Chemical-resistantSpecial coatings or materials resist erosion from acids, alkalis, and other chemicals.
Insulation/Thermal ProtectionSuitable for high or low-temperature operating environments.
2. Classification Standards (e.g., common criteria)
China Standard (GB)
GB 21148-2020 "Foot Protection - Safety Shoes": Specifies performance requirements for anti-crushing, anti-piercing, and anti-static, etc.
Label Example:
GB 21148-2020 An1Anti-smash + 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 Buying Points
Suitable for working environment：
Construction Site: Priority - Anti-Crush, Anti-Pierce, and Anti-Slip.
Chemical/Electronic Factory: Requires antistatic or insulating function.
Metallurgy/Welding: Choose styles that are heat-resistant or metal splash-proof.
Size and Comfort：
One and a half sizes larger than everyday shoes (requires thick socks), ensuring toe room.
Check for any discomfort at the toe area and ensure the insole fits the arch of the foot when trying on the shoes.
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.
Insulated footwear 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 daily).
5. Cautionary Notes
Disabling in non-protective scenariosDress code may affect comfort, and some features (such as static dissipation) require the use of conductive flooring.
Special environment compatibilitySelect specialized styles (such as insulated boots, heat-resistant boots) for extreme cold or high-temperature environments.
