Sample questions

Your foreman gives you a five-step set of verbal instructions. What is the best way to be sure you understood them?

  1. Say you understand and begin working
  2. Ask a coworker later what was meant
  3. Do the steps you remember and then stop
  4. Repeat the steps back in your own words
Show the answer

D. Repeat the steps back in your own words

Restating the instructions lets the foreman correct any misunderstanding before work starts. Saying you understand when you are unsure only delays the mistake.

Which hammer should be used to strike a cold chisel or a punch?

  1. Ball-peen hammer
  2. Claw hammer
  3. Tack hammer
  4. Wooden mallet

A rectangular footing trench outline is 28 ft by 44 ft. How many feet of string line are needed to go once around it?

Answer in ft.

Show the answer

144 ft

Perimeter = 2 × (L + W) = 2 × (44 + 28) = 2 × 72 = 144 ft.

Reference: Perimeter of a rectangle: P = 2(L + W)

A drill has a two-prong plug and a square-within-a-square symbol on its nameplate. What does this mean?

  1. It is broken and the ground pin has been cut off
  2. It is for use on 240-volt circuits only
  3. It is approved for use in wet locations
  4. It is double insulated and needs no ground pin
Show the answer

D. It is double insulated and needs no ground pin

The double-square mark shows double insulation, which is an accepted alternative to an equipment grounding conductor. It does not make the tool safe for wet locations.
