Understanding Safety Ratings: EH, ASTM, and More for Work Footwear
What Are EH Rated Work Shoes?
EH rated work shoes are footwear certified to protect against electrical hazards, meeting ASTM F2413-18 standards with ≥1,000 Ohms resistance.
The EH (Electrical Hazard) rating ensures shoes reduce the risk of electric shock in dry conditions. Testing involves exposing the footwear to 18,000 volts at 60 Hz for one minute with no current flow exceeding 1.0 mA.
How EH Testing Works
- Ohm threshold: Shoes must maintain ≥1,000 Ohms resistance (ASTM F2413-18).
- Voltage limit: Protects against ≤600V in dry environments [VERIFY: exact voltage limit].
- Conditional protection: EH ratings void if soles are wet or damaged.
Jobs Requiring EH Ratings
- Electricians
- Utility workers
- Telecom technicians
What’s the Difference Between Steel Toe and Composite Toe Work Shoes?
Steel toe work shoes use metal caps for impact protection, while composite toes use non-metallic materials like Kevlar or fiberglass, weighing 30-50% less.
| Feature | Steel Toe | Composite Toe | |
| ------------------ | --------------------- | --------------------- | |
| Weight | 1.8-2.2 lbs per shoe | 1.2-1.5 lbs per shoe | |
| Conductivity | Conducts electricity | Non-conductive | |
| ASTM Rating | I/75, C/75 | I/75, C/75 | |
| Best For | Heavy industrial use | Electrical work, airports |
Trade-offs:
- Steel toes are heavier but more durable against extreme impacts.
- Composite toes avoid metal detectors but may crack under repeated stress.
How Does ASTM Certification Work for Work Shoes?
ASTM certification verifies work shoes pass impact, compression, and puncture tests under ASTM F2413-18 standards.
Key Tests:
- Impact resistance (I/75): Drops a 50-lb weight from 1 foot onto the toe cap [VERIFY: exact test parameters].
- Compression resistance (C/75): Applies 2,500 lbs of force to the toe area.
- Puncture resistance (PR): Uses a 120-lb nail at 1.5 inches per minute.
Labeling Requirements:
Certified shoes must display:
- "ASTM F2413-18"
- Specific ratings (e.g., I/75/C/75) inside the tongue.
Which Safety Ratings Matter Most for Your Job?
Match work shoe safety ratings to your job’s hazards—slip resistance reduces food service falls by 50% (NIOSH).
| Job Type | Required Ratings | Example Shoes | |
| ---------------- | -------------------------------- | ----------------------------- | |
| Construction | ASTM I/75, C/75, PR | Heavy-duty steel toe | |
| Electrical | EH, ASTM I/75 | Composite toe with EH rating | |
| Food Service | Slip-resistant (SATRA TM144) | Non-slip soles |
Most overlooked:
- Healthcare: Slip-resistant soles (≥0.40 coefficient of friction).
- Warehouses: Metatarsal guards for pallet impacts.
What Are the Biggest Mistakes When Buying Rated Work Shoes?
40% of workers wear shoes past the 12-month replacement window, compromising safety (VERIFY: industry survey).
Top 3 Mistakes:
- Ignoring width/fit: Tight shoes reduce protection—toe caps need 0.5" clearance.
- Assuming all "safety toes" meet ASTM: Look for "ASTM F2413-18" labeling.
- Overlooking sole wear: Replace if tread depth is <1/8" or cracks appear.
Hidden risk: Counterfeit ratings—always verify certifications with the manufacturer.
How Do You Verify Work Shoe Safety Ratings?
Genuine work shoe safety ratings display ASTM/EH markings inside the tongue or sole.
Steps to Verify:
- Check for embossed "ASTM F2413-18" or "EH" labels.
- Cross-reference with the manufacturer’s certification database.
- Avoid shoes with stick-on or printed labels—these are often counterfeit.
Red Flags:
- No markings on the shoe or box.
- Vague claims like "meets safety standards" without ASTM codes.
What’s the Bottom Line on Work Shoe Safety Ratings?
Always match work shoe safety ratings to your job’s specific hazards.
- Verify ASTM/EH markings—don’t rely on generic "safety" claims.
- Replace shoes when soles wear below 1/8” or after 12 months.
- Prioritize fit—cramped toes negate protection.
