Ensure all personnel involved are authorized and trained in lockout/tagout procedures.

Group Lockout Procedure

Follow these steps for a typical group lockout procedure using the Brady Extra-Large Group Lock Box:

1. Isolate Energy Sources: The authorized supervisor or lead person identifies all energy isolation points for the equipment requiring maintenance or service. They then apply individual safety locks to each isolation point, securing the equipment in a zero energy state.
2. Collect Keys: The keys for all the individual safety locks applied in Step 1 are collected and placed inside the Brady Group Lock Box.
3. Secure the Lock Box: The supervisor or lead person closes the lock box and secures it with their personal safety lock through the designated hasp.
4. Individual Worker Lockout: Each authorized worker involved in the maintenance or service then attaches their own personal safety lock to one of the available holes on the lock box. This ensures that the lock box cannot be opened, and thus the equipment keys cannot be accessed, until every worker has removed their personal lock.
5. Perform Work: All workers proceed with their assigned maintenance or service tasks, knowing the equipment is safely locked out.
6. Remove Personal Locks: Upon completion of their work, each worker removes their personal safety lock from the lock box.
7. Re-energize Equipment: Once the last worker has removed their personal lock, the supervisor or lead person can then remove their master lock from the lock box, retrieve the keys, and re-energize the equipment after ensuring all personnel are clear and the area is safe.

6. Maintenance

The Brady Extra-Large Group Lock Box is constructed from durable steel and requires minimal maintenance. To ensure longevity and proper function:

• Cleaning: Wipe down the exterior with a damp cloth as needed to remove dust and grime. Avoid abrasive cleaners or solvents that could damage the finish.
• Inspection: Periodically inspect the hinges, latch, and handle for any signs of wear, corrosion, or damage. Ensure all openings for padlocks are clear and unobstructed.
• Storage: Store the lock box in a dry, clean environment when not in use to prevent rust and maintain its condition.

7. Troubleshooting

Most issues with the Brady Group Lock Box can be resolved with simple checks:

• Difficulty Latching/Unlatching: Check for any debris obstructing the latch mechanism. Ensure the lid is properly aligned with the base. If the issue persists and there is no visible damage, contact customer support.
• Corrosion/Rust: If minor surface rust appears, it can often be removed with a rust-inhibiting cleaner. For significant corrosion, consider replacing the unit to ensure safety and integrity.
• Missing Keys: This is a critical safety concern. Immediately halt all work, re-verify the lockout status of the equipment, and follow your organization's emergency procedures for lost keys during lockout/tagout. The lock box itself does not prevent key loss if not properly managed.
