Employees are prohibited from? (Tampering)

Employees are prohibited from? (Tampering)

• A. Breaking seals on interlocking appliances or other equipment, except when authorized to do so.
• B. Painting on equipment
• C. Turning off all signals
• D. Eating on duty

Answer: (A)

The key idea here is that safety-critical signaling and interlocking equipment must remain untouched unless you have explicit authorization. Seals on interlocking appliances are there to show that the equipment hasn’t been opened or altered. Breaking those seals could let someone bypass safety checks, create unsafe conditions, and mislead others about the equipment’s status. So the rule specifically forbids breaking seals on interlocking devices or other equipment unless you’re authorized to do so for maintenance or testing, making this option the correct one. Painting on equipment and eating on duty aren’t tied to tampering with safety devices, and turning off all signals would be a dangerous act but isn’t the direct tampering-with-seals example the question is targeting.
