Which of the following is an interlock safety example related to oil temperature?

• A. Oil temperature is at a safe level
• B. Oil change required
• C. Oil filter clean
• D. Oil color clear

Answer: (A)

Interlock safety hinges on conditions that must be safe for the equipment to run. Oil temperature being at a safe level is a typical interlock check because it confirms the machine can operate without overheating. If the oil were too hot, the interlock would prevent starting or continuing operation to protect the system. The other options describe maintenance or status indicators (needing an oil change, a clean oil filter, or oil color) and don’t directly represent the safety condition that controls whether the machine can run.
