EH rated means Electrical Hazard under ASTM F2413: the boot's sole and heel withstand 18,000 volts for a minute, dry, as secondary protection against accidental contact. This guide covers the test behind the letters, the wet-conditions fine print, EH vs dielectric vs SD vs CD, the label line, and a worked apprentice boot spec.

Steel toe and composite toe boots meet the same ASTM F2413 protection level when rated, so the real decision is the cap's secondary properties: weight, conductivity, metal-detector behavior, electrical-hazard pairing, and cost. This guide decodes every difference under OSHA 1910.136 and walks a worked example of choosing a toe type by job.

Safety boots only protect you if their ASTM F2413 rating matches your hazards. This guide decodes the I/C, EH, PR, Mt, and SR markings stamped inside every compliant boot, compares steel and composite toe caps, covers waterproofing and proper fit, and walks through selecting the right work boots for a real job site step by step.
