How to find the right Lockout & Tagout Devices AI guide
Written by an AI model from its trained knowledge.
What the AI looks for in Lockout & Tagout Devices
- Breaker style compatibility
- Match the device to the breaker: single-pole or multi-pole, tie-bar handles, and clamp-on versus pin-in (pin-in suits many miniature and DIN-rail breakers). Breaker lockouts fit very differently across panel types, and a loose fit lets the handle move.
- Valve size and type
- Size gate valve covers to the handwheel diameter, and choose ball and butterfly valve lockouts that fit the handle shape and position. An undersized or oversized valve device can be rotated or slipped off.
- Plug lockouts
- Choose an enclosure sized to the plug and cord that leaves no access to the prongs. For cord-and-plug equipment, controlling the plug is the isolation.
- Multi-worker hasps
- Use hasps or group lock boxes sized to the maximum crew on a job. Each authorized worker needs to apply a personal lock.
- Removal resistance
- The device must not be removable without its lock or without excessive force or unusual techniques. This is the substantiality requirement for energy-isolating devices under OSHA 1910.147.
Brands that matter
- Brady: Wide breaker, valve and plug lockout range with fit guidance.
- Master Lock: Hasps, valve and electrical lockout devices.
- Panduit: Electrical lockout devices, especially for breakers.
What to avoid
- Universal breaker lockouts bought without checking your panel's breaker style.
- Devices that can be slid off with the lock still attached.
- Single-hole hasps for jobs with several workers.
