Are Steel Toe Boots Safe for Electricians? EH Ratings Explained
Electricians and safety managers ask a fair question: does a metal toe cap increase the risk of shock? The short answer is no, provided the boot is rated for electrical hazard work — a steel toe is not a conductor to earth on its own. What creates risk is a boot that is not insulated, not maintained, or specified against the wrong marking.
This article explains what the two relevant markings actually test, why static-dissipative footwear is the wrong choice for electrical work, and which ROCKROOSTER models carry the correct rating.
Why the steel toe concern is largely misplaced
Electric shock travels through a path to earth. In a properly built safety boot, the toe cap sits on top of an insulating insole and is separated from the outsole, so it has no continuous path to the ground. The cap itself is not the issue; the boot’s insulation and condition are.
Composite toes are equally acceptable. They are non-metallic, lighter and do not conduct cold, but the electrical protection still comes from the boot’s construction, not from the absence of steel. A composite boot without an EH rating offers no more electrical protection than a steel boot without one.
What EH and SD actually mean
Two markings appear on safety footwear and they are frequently confused.
EH — electrical hazard. Under ASTM F2413, EH footwear is tested at 18,000 volts (60 Hz) for one minute, with leakage current required to remain below the threshold set by the standard. The test is performed in dry conditions. EH footwear is a secondary safeguard: it reduces the chance of a shock path through the feet when accidental contact occurs. It is not dielectric PPE and does not make live work safe.
SD — static dissipative. SD footwear is designed to bleed static charge to the ground, which is exactly what you want in electronics assembly and paint lines, and exactly what you do not want near live conductors. An SD boot is deliberately conductive within defined limits. Buying an SD-rated boot for electrical work because it sounds like “anti-static protection” is a specification error.
Some models carry both a toe-cap rating and an EH marking, for example ASTM F2413-18 I/75 C/75 EH. Others are soft-toe boots certified to ASTM F2892, the standard for protective footwear without a safety toe, with EH. Both are valid; which you need depends on whether a toe cap is required by the site’s hazard assessment.
| Marking | What it covers | Suitable for electrical work |
|---|---|---|
| ASTM F2413 I/75 C/75 EH | Impact and compression plus electrical hazard, with toe cap | Yes |
| ASTM F2892 EH | Electrical hazard, soft toe, no toe cap | Yes, where no toe cap is required |
| ASTM F2413 I/75 C/75 SD | Impact and compression plus static dissipation | No — conductive by design |
| No marking | Basic footwear | No |
ROCKROOSTER models with EH protection
AK669 Woodland — composite toe, ASTM F2413-18 I/75 C/75 EH. The product data lists protection against electrical shock up to 18,000 V, a HydroGuard waterproof membrane, oiled crazyhorse leather and a rubber outsole resistant to contact heat up to 500°F. Rated AS 2210.3 Class I S1 WR HRO SRC. This is the model to specify where a toe cap and wet conditions combine.
AP611 Norwood — soft toe, ASTM 2892-11 EH. Full grain tumbled leather over a cork midsole with a true leather welt, on a wedge outsole. Chosen by electricians who work indoors and do not need a toe cap, and who want a boot that can be resoled.
AP360 — soft toe wedge, ASTM F2892-18 EH, oil- and slip-resistant outsole, normal width. The lighter, standard-width alternative for maintenance teams.
By contrast, the AK227, AK222, AK050, AK229 and AK232 carry static-dissipative markings. They are the right boots for electronics and clean-room work; they should not be issued as electrical hazard footwear.
The limits of an EH rating
An EH marking is not an arc-flash rating. Footwear marketed as arc-rated is tested to a different standard and is a separate specification decision; an EH boot alone does not satisfy an arc-flash PPE category. EH footwear is also tested dry, so a saturated boot should be taken out of service until it has dried and been inspected.
Finally, EH protection degrades. Contamination with metal dust, cuts through the outsole, or a worn-through insole can create a conductive path that the original test never anticipated. Electrical workers should inspect boots before each shift and replace them at the first sign of sole penetration or liner damage.
Specifying footwear for an electrical crew
- Confirm whether the hazard assessment requires a toe cap. If not, an F2892 EH soft-toe boot is lighter and more flexible.
- Specify EH explicitly. Do not accept “antistatic” or “SD” as a substitute.
- Match the outsole to the environment: SRC slip resistance for wet floors, HRO for hot surfaces.
- Confirm the certification documents. ROCKROOSTER lists AS 2210.3 certification through CMI (certificate PC10225) and CE marking to EN ISO 20345:2011 on the S1 models.
- Plan replacement. Electrical footwear is consumable PPE, not a lifetime purchase.
