Each employee involved in a lockout tagout procedure should use at least one lock each. For example, if 5 authorized employees are working together on the same maintenance or repair job, there should be at least five locks used in the procedure. Each employee must also place their personal safety locks, and each lock can only be removed by the person that placed them.
The use of a lockout tagout lock box can help streamline this process even further. Once all employees have placed their personal safety padlocks on the relevant isolation points, they can place the keys to these padlocks in the lock box. Each member of the team can then place another personal safety padlock on the lock box itself.
