Under lockout/tagout planning requirements, a simple procedure is permitted when which condition exists?

• A. Job or task continues for more than one work period
• B. Multiple employers
• C. Multiple energy sources
• D. None of the above

Answer: (D)

A simple procedure is allowed only when the task can be performed with a clearly isolated energy source, no stored or residual energy, and the energy-control device is under the exclusive control of the authorized employee performing the work, with no likelihood of unexpected energization or hazards changing during the task. If any of these conditions are not met—such as when the job will span more than one work period, involves multiple employers, or involves multiple energy sources—the simplified approach does not apply and a full lockout/tagout process must be used. Since each of the listed scenarios violates the tight constraints for a simple procedure, none of them qualifies. Therefore, none of the above describes a situation where a simple procedure is permitted.
