Electrical Hazard Protection in Safety Shoes
Electrical hazard (EH) rated safety shoes provide insulation against accidental contact with live electrical circuits. Understanding EH protection helps ensure workers are properly protected in environments with electrical exposure.
Insulated Soles
EH-rated shoes feature insulated soles that prevent electrical current from passing through the foot to the ground.
ASTM EH Rating
Electrical hazard protection is specified in ASTM F2413 as EH, indicating the shoe insulates against accidental live contact.
Not for All Environments
EH shoes are NOT suitable where static dissipative or conductive footwear is required—different protection is needed in those cases.
Supplementary Protection
EH protection is secondary to avoiding electrical hazards—always de-energize equipment before working near live circuits.
Understanding Electrical Hazard Protection
Electrical hazard (EH) protection in safety footwear consists of insulated soles that prevent electrical current from flowing through the shoe and through the worker's body to ground. EH protection is rated under ASTM F2413 and is separate from other safety features like toe protection.
How EH Protection Works
EH-rated shoes feature soles made from materials that do not conduct electricity, preventing the completion of a circuit between the worker and ground when they contact a live electrical source. The insulation is tested at 18,000 volts (in the ASTM standard), and EH shoes must pass this test without allowing current to flow through the shoe.
When EH Protection Is Needed
EH-rated footwear is appropriate for workers who may accidentally contact live electrical circuits—electricians, utility workers, construction workers near electrical infrastructure, and maintenance personnel. EH shoes provide a secondary layer of protection when primary safety measures (de-energizing equipment, using insulating tools) fail or are unavailable.
Important Limitations
EH-rated footwear is NOT appropriate for all electrical work environments. Workers who need static dissipative (SD) or conductive (CD) footwear require different protection—SD shoes allow controlled static discharge while CD shoes prevent static accumulation in explosive environments. EH shoes are specifically for protection against accidental live circuit contact and should not be used where SD or CD properties are required.
Sourcing Considerations
For B2B buyers, clearly identify whether EH, SD, or CD protection is needed—these are mutually exclusive requirements. EH shoes typically use special insulated midsoles, which may affect comfort and weight compared to non-EH safety shoes. Request test certificates demonstrating the shoes have passed ASTM or EN ISO electrical testing requirements for your target market.
