Full definition
Protective footwear designed to shield workers' feet from workplace hazards including impact (falling objects), compression (rolling loads), puncture (sharp objects penetrating the sole), electrical hazard (EH — insulation from electrical shock), static dissipation (SD — controlled charge bleed-off), chemical splash, and slip/fall. Per ASTM F2413 (current US standard): impact protection rated I/75 (75 ft-lb) or I/50, compression rated C/75 or C/50, puncture resistance (PR — steel or composite plate in the sole), electrical hazard (EH — withstands 18,000V under dry conditions), and metatarsal protection (Mt). Toe cap materials: steel (traditional, heaviest, conductive), composite (fiberglass/Kevlar — lighter, non-metallic detector friendly, thermal insulator), and aluminum (lightweight, thinner profile). In Mexico: NOM-113-STPS-2009 specifies requirements for safety footwear in Mexican workplaces. Dielectric footwear (rated for electrical insulation) is essential when combined with dielectric mats and gloves for complete electrical PPE. Sole: oil-resistant rubber or PU, slip-resistant tread (SRC rating per EN ISO 20345 — tested on both ceramic and steel with water and glycerin).
