MEOC Case Analysis & Practical Application 2

Question 1

You are excavating near an underground utility line marked 18 inches from your planned cut. The standard safe excavation distance from a marked utility is:

Accepted Answer

24 inches

Answer

OSHA and most utility protection laws require maintaining at least 24 inches (2 feet) of clearance when excavating near marked utilities.

Question 2

During a grading job, you notice the spoil pile is too close to the excavation edge and soil is starting to slip. Your FIRST action should be:

Accepted Answer

Stop work and relocate the spoil pile

Answer

A spoil pile too close to the excavation edge creates a surcharge load that can cause cave-ins, so work must stop and the pile relocated before continuing.

Question 3

You arrive at a residential site and find a gas line marked 3 feet from your dig area. What should you do before breaking ground?

Accepted Answer

Call 811 to confirm the mark is current and accurate

Answer

Always call 811 (or the local one-call center) to verify that all utility locates are current before beginning any excavation, even if markings are visible.

Question 4

While operating a mini excavator on a hillside, the machine starts to feel unstable during a swing. The safest corrective action is:

Accepted Answer

Lower the boom and bucket to reduce the center of gravity

Answer

Lowering the boom and bucket reduces the machine's center of gravity and improves stability when operating on slopes.

Question 5

You are asked to lift a concrete barrier with the excavator bucket. The load is within the machine's rated lifting capacity. What is the key consideration before lifting?

Accepted Answer

Whether the attachment is rated and rigged for lifting operations

Answer

Using an excavator for lifting requires a properly rated lifting attachment and rigging; the bucket alone is not designed or certified for suspended load lifting.
