Buying Guide: Key Purchase Considerations
- Plug size compatibility: Measure plug diameter and length to ensure the lockout device fits without leaving gaps that could allow energization.
- Locking capacity: Consider the number of locking holes and whether multi-person locking is needed for higher security standards in your facility.
- Material durability: Industrial-grade polypropylene is common, valued for non-conductivity and resistance to tampering; evaluate environmental conditions where the device will be used (dust, moisture, chemicals).
- Labeling and visibility: A bold warning label helps reinforce safety messaging and compliance with lockout/tagout procedures.
- Compatibility with cords and controls: For hardened or oversized equipment, look for oversized lockouts or bag-style containment that can accommodate extension cords or complex control panels.
- Ease of use: Devices should allow quick application and removal by trained personnel, reducing downtime while maintaining safety.
- Regulatory alignment: Ensure solutions meet OSHA or local electrical safety requirements for lockout/tagout activities in your industry.
- Security vs. accessibility: Higher-security lockouts with multiple locking holes may be preferable in environments with higher risk of tampering.
