  1. When cutting PVC pipe with a ratchet cutter, what is the most important technique to ensure a square cut?

    Answer: Rotate the pipe while advancing the cutter blade gradually

    Rotating the pipe while slowly advancing the blade keeps even pressure around the circumference and produces a square, clean cut.

  2. A handyman is patching a 6-inch hole in drywall. Which method provides the strongest repair?

    Answer: Use a California patch with a backer board

    A California patch uses the drywall paper facing as the backer, creating a flush, rigid repair that is stronger than mesh-only patches for larger holes.

  3. What is the purpose of a p-trap under a sink drain?

    Answer: To hold water that blocks sewer gases from entering the building

    The water retained in the curved P-trap creates a seal that prevents toxic and odorous sewer gases from rising up through the drain.

  4. Which OSHA requirement must a handyman follow when working on a ladder above 6 feet on a residential job site?

    Answer: Appropriate fall protection or a ladder with non-slip feet must be used

    OSHA requires fall protection measures at heights of 6 feet or more in construction, which includes using properly secured ladders with non-slip feet.

  5. When installing a new light fixture, what should you do FIRST before beginning any wiring work?

    Answer: Turn off the breaker and verify power is off with a non-contact tester

    Always de-energize the circuit at the breaker panel and confirm with a non-contact voltage tester before touching any wiring.

  6. What does the 'R-value' of insulation measure?

    Answer: The thermal resistance — how well it resists heat transfer

    R-value measures thermal resistance; a higher R-value means the insulation slows heat transfer more effectively.

  7. A wood deck board has a crown (slight bow across its width). How should it be installed?

    Answer: Crown facing up, so water sheds away from the center

    Deck boards should be installed crown-up so the high center sheds water to the sides, preventing pooling and rot.
