This OSHA Safety Lockout/Tagout (LOTO) Padlock is the premium combination of a Di-Electric (Non-Conductive) Shackle with a Master Key (MK) System — delivering both maximum electrical safety and hierarchical key control in one device. Each padlock carries its own unique individual key, while a single Master Key held by the supervisor or safety officer can override and open all locks in the set.
The fully non-conductive polymer shackle ensures zero electrical conductivity, making this padlock the highest-specification choice for electrical maintenance environments where both strict individual lock ownership and emergency supervisory override are mandatory requirements.
Fully compliant with OSHA CFR 29 Part 1910.147 for the Control of Hazardous Energy.
