The FIRST thing to do to ensure that a refrigeration unit will not start while undergoing repairs is to do what?

🔍 Key Concepts

• Lockout/Tagout (LOTO) safety procedures for machinery under repair • Hierarchy of controls: isolate energy source before mechanical blocking or warnings • Difference between administrative controls (warnings, log entries) and physical controls (disconnecting and tagging power)

💭 Think About

• Before anyone touches the unit, what must be done to the source of electrical power that can start it? • Which option provides a positive physical means of preventing automatic or accidental start, not just a warning? • If someone new walks into the area and doesn’t know repairs are happening, which option would still keep the unit from starting?

✅ Before You Answer

• Identify which choice actually controls the energy source rather than just recording or talking about it • Check which action is normally required by lockout/tagout procedures before maintenance • Eliminate any option that would still allow the unit to be started remotely or automatically despite the action taken
