How should equipment be left when unattended?

• A. Turned off, brakes set, wheels scotched
• B. Left running to maintain system
• C. Keys left in ignition
• D. Positively no maintenance actions

Answer: (A)

Securing equipment when it’s not in use is about preventing movement and accidental startup. The best practice is to turn the engine off, set the parking brakes, and place wheel scotches against the wheels. Turning off the engine removes the risk of an unexpected startup and reduces fuel use and wear. The parking brakes hold the machine in place, providing a reliable mechanical restraint. Wheel scotches add a extra layer of security by physically blocking any rolling, which is especially important on slopes or uneven ground. Together, these steps greatly reduce the chance of a runaway machine and protect workers nearby. Leaving the unit running wastes fuel and exposes moving parts to hazards, while leaving keys in the ignition could allow unauthorized use.
