This OSHA Safety Lockout/Tagout (LOTO) Padlock features a Di-Electric (Non-Conductive) Shackle — making it specifically engineered for use in electrical hazard environments. Unlike standard metallic shackle padlocks, the di-electric shackle is made from non-conductive nylon/polymer material, providing full electrical insulation and eliminating the risk of accidental conductivity or arc flash.
It operates on a Different Key (DK) System, meaning every padlock has its own unique key and no two locks in the set can be opened by the same key. This ensures strict individual lock ownership — a critical requirement under OSHA LOTO regulations for multi-employee energy isolation programs.
Fully compliant with OSHA CFR 29 Part 1910.147 for the Control of Hazardous Energy.
