EH (Electrical Hazard) safety shoes and anti-static safety shoes serve different electrical safety purposes. EH footwear is designed to reduce the risk of electric shock under specified test conditions, while anti-static footwear helps dissipate static electricity to reduce electrostatic buildup.
These properties are not interchangeable. EH footwear is intended for certain electrical hazard environments, whereas anti-static footwear is used where static control is important, such as electronics manufacturing and some flammable-material handling areas. The right choice depends on the workplace risk assessment, applicable standards, and the footwear’s verified performance.
A. How Are EH and SD Safety Shoes Tested Under ASTM Standards?
In the United States, ASTM F2413 specifies performance requirements for protective footwear, while ASTM F2412 describes test methods used to evaluate footwear performance.
Electrical Hazard (EH): EH footwear is evaluated for its ability to resist electrical hazards under specified test conditions. Buyers should check the applicable ASTM requirements and the product’s test documentation rather than relying on voltage claims alone.
Static Dissipative (SD): SD footwear is designed to help control static buildup while maintaining electrical resistance within the required range. Its suitability depends on the applicable standard, the intended workplace, and the wider static-control system.
EH and SD footwear serve different purposes. Neither marking should be treated as a substitute for assessing the actual electrical risks at the workplace.

B. EH vs. Anti-Static Safety Shoes Under European Standards
Under EN ISO 20345, anti-static footwear is marked with the symbol A and is designed to limit electrostatic charge buildup through controlled electrical resistance.
Anti-static footwear is not electrical insulating footwear. For electrical work involving hazardous voltages, buyers must identify the appropriate insulating footwear standard and verify that the product is tested and certified for the intended application.
When sourcing footwear for international markets, do not assume that an EH marking under a US standard is automatically equivalent to an EN ISO 20345 classification or a European electrical-insulation rating. Confirm the relevant standard, product marking, and supporting test documentation for each target market.
How to Choose Between EH and Anti-Static Safety Shoes
The right footwear depends on the hazards present at the workplace.
-
Electrical installation and maintenance: Evaluate footwear specifically tested for the relevant electrical hazard requirements. EH footwear may be appropriate for certain applications, but it does not replace required electrical protective equipment or safe work procedures.
-
Electronics and precision manufacturing: Anti-static or static-dissipative footwear may be needed as part of an approved electrostatic discharge (ESD) control program.
-
Flammable-material handling: Assess the ignition risks and the complete static-control system. Footwear alone does not guarantee protection against fire or explosion.
-
Mixed-risk workplaces: Consider whether multiple hazards are present and select footwear that meets all applicable requirements without assuming that one electrical property covers every risk.
For importers and wholesalers, confirm the target market, applicable standards, product markings, test reports, and end-user requirements before finalizing a purchase.
1. Can you wear anti-static shoes for electrical work?
Not necessarily. Anti-static footwear is designed to dissipate static electricity and is not intended to provide electrical insulation. Select footwear according to the specific electrical hazards and applicable safety requirements.
2. Are EH safety shoes the same as ESD shoes?
No. EH footwear is designed to reduce certain electrical shock risks under specified test conditions, while ESD footwear helps control electrostatic discharge. They serve different safety purposes.
3. What is the difference between ASTM EH and SD footwear?
EH refers to electrical hazard protection, while SD stands for static dissipative. Buyers should verify the applicable ASTM requirements and product test documentation for the intended use.
4. Can safety shoes be both EH and anti-static?
These properties involve different electrical performance objectives. Do not assume a shoe can meet both requirements simply because of its materials or construction. Verify the specific product’s test results, applicable standards, and suitability for the intended workplace.
