Step-by-step explanation:
Combination locks, such as those used for lockers or safes, should have their combination changed periodically for security reasons. The frequency of combination change may vary depending on the specific situation, but a general recommendation is to change the combination at least once a year.
Some common scenarios when changing the combination is advisable include:
- When a combination lock is first assigned to a user, as a security measure to ensure that only the user knows the combination.
- When there is any suspicion that the combination may have been compromised, such as when a keyholder leaves an organization or when there is a potential security breach.
- When a significant amount of time has passed since the last combination change, as a precautionary measure to enhance security.
By regularly changing the combination on combination locks, users can maintain the security of their valuables or confidential information.
