The free daily OSHA 30-Hour Construction set includes crawlable question text, answer choices, correct answer labels, objective mapping, and source links. Only the first SEO card includes answer explanations and any extra learning features. Pro-only bank questions stay locked; this section mirrors only the 10 free daily questions already shown on this page.

Question 1 A concrete saw operation exposes an employee to 95 dBA for the full eight-hour shift, which exceeds the Table D-2 duration for 95 dBA. What is the correct control approach?

Answer choices

  1. A. Use feasible engineering or administrative controls and provide hearing protection as needed for any remaining overexposure.
  2. B. Rely only on annual hearing tests because testing controls noise exposure.
  3. C. Ignore duration because only the peak decibel value matters.
  4. D. Provide a hard hat and treat it as hearing protection.

Correct answer

Use feasible engineering or administrative controls and provide hearing protection as needed for any remaining overexposure.

Section 1926.52 evaluates both level and duration and requires feasible controls for exposure above Table D-2, with PPE for remaining exposure. Source basis: 29 CFR 1926.52(b) and Table D-2.

Wrong-answer review

  • B. Rely only on annual hearing tests because testing controls noise exposure.: Incorrect. Audiometry monitors hearing but does not reduce noise.
  • C. Ignore duration because only the peak decibel value matters.: Incorrect. Noise risk under the table depends on both sound level and exposure duration.
  • D. Provide a hard hat and treat it as hearing protection.: Incorrect. Standard head protection is not hearing protection.

Extra learning features

Why candidates miss this

The distractor ‘Rely only on annual hearing tests because testing controls noise exposure.’ is tempting because it simplifies the control approach. The decisive clue that eliminates it is the requirement for *feasible* engineering or administrative controls, demonstrating a more comprehensive strategy. Likely wrong answer: Rely only on annual hearing tests because testing controls noise exposure. Review focus: 29 CFR 1926.52 – Occupational noise exposure

Objective/domain: Health Hazards in Construction

Source: 29 CFR 1926.52 – Occupational noise exposure

Question 2 During a high-rise pour, laborers stand directly below a concrete bucket as it is hoisted into position. What must the supervisor change?

Answer choices

  1. A. Have the workers crouch below the bucket path so the operator can see over them.
  2. B. Keep employees from working beneath the concrete bucket while it is being elevated or lowered.
  3. C. Allow the workers to remain if the bucket has been inspected that morning.
  4. D. Require hard hats and continue the lift directly over the crew.

Correct answer

Keep employees from working beneath the concrete bucket while it is being elevated or lowered.

Objective/domain: Construction Focus Four Hazards

Source: 29 CFR 1926.701 – Concrete and masonry construction: General requirements

Question 3 A contractor launches a new near-miss reporting system, but workers do not understand what qualifies as a near miss or how reports are submitted. What is the best next program step?

Answer choices

  1. A. Remove the reporting system until every worker can define all OSHA standards from memory.
  2. B. Assume the written policy is self-explanatory and measure workers only on the number of reports.
  3. C. Discipline workers who ask questions because the procedure has already been posted.
  4. D. Train workers on hazard and near-miss recognition, the reporting process, and how reported information will be used.

Correct answer

Train workers on hazard and near-miss recognition, the reporting process, and how reported information will be used.

Objective/domain: Managing Safety and Health

Question 4 Weekly inspections repeatedly find extension cords crossing a stair landing. Each time the cord is moved, but the condition returns because power distribution has not been changed. What is the best safety-management response?

Answer choices

  1. A. Stop documenting the finding because it has already appeared on prior checklists.
  2. B. Correct the immediate trip hazard and address the recurring system cause, such as power distribution or routing.
  3. C. Continue moving the cord during inspections without investigating why the condition returns.
  4. D. Treat the issue as solely a worker-attention problem and make no physical change.

Correct answer

Correct the immediate trip hazard and address the recurring system cause, such as power distribution or routing.

Objective/domain: Managing Safety and Health

Question 5 A worker uses an extension ladder to access a roof. The side rails stop level with the roof edge and there is no secured handhold. What correction is required for safe access?

Answer choices

  1. A. Place a warning cone at the ladder base and keep the existing setup.
  2. B. Increase the ladder angle until the top rung is closer to the roof edge.
  3. C. Have a coworker stand at the bottom while the worker steps sideways onto the roof.
  4. D. Extend the ladder side rails at least 3 feet above the landing or use the standard’s secured-ladder/grasping-device alternative.

Correct answer

Extend the ladder side rails at least 3 feet above the landing or use the standard’s secured-ladder/grasping-device alternative.

Objective/domain: Stairways and Ladders

Question 6 A trench wall is visibly sloughing and a supervisor proposes adding hard hats rather than removing workers and correcting the cave-in hazard. According to OSHA’s hierarchy of controls, what is the sound response?

Answer choices

  1. A. Keep employees in the trench as long as they wear hard hats.
  2. B. Limit trench entry to experienced workers without changing the protective system.
  3. C. Add safety glasses because more PPE always compensates for an uncontrolled structural hazard.
  4. D. Remove the exposure and correct the cave-in hazard with the required protective measures; PPE alone is not an adequate control.

Correct answer

Remove the exposure and correct the cave-in hazard with the required protective measures; PPE alone is not an adequate control.

Objective/domain: Personal Protective Equipment

Source: OSHA Recommended Practices – Hazard Prevention and Control

Question 7 An optional module presents a frayed extension cord with visible conductor insulation. Which learning outcome best aligns with the controlling standard?

  2. B. Teach that rubber-soled work boots substitute for controlling energized circuits.
  3. C. Teach that caution tape alone makes damaged electrical equipment safe to use.
  4. D. Teach that experienced workers may continue using frayed cords if the task is short.

Correct answer

Recognize the electrical contact hazard and remove or control it before employees are exposed.

Objective/domain: Optional and Expanded Construction Safety Topics

Source: 29 CFR 1926.416 – General electrical requirements

Question 8 After a scaffold incident, an employee is formally admitted to a hospital for inpatient treatment. The employer learns of the admission that afternoon. What must the employer do under 29 CFR 1904.39?

Answer choices

  1. A. Do not report it unless at least three workers are hospitalized.
  2. B. Report it within 8 hours because every hospitalization uses the fatality deadline.
  3. C. Wait until the employee is discharged before deciding whether to notify OSHA.

Correct answer

Report the work-related inpatient hospitalization to OSHA within 24 hours.

Question 9 During setup, the load chart and required operating procedures are not available in the cab and the crew cannot verify the planned configuration. What is the safest compliant response?

Answer choices

  1. A. Continue because experienced operators may work from memory and multitask.
  2. B. Increase lift speed to reduce the time the operator is distracted.
  3. C. Let the signal person estimate capacity so the operator can keep lifting.
