What this chapter covers

Introduction to OSHA is one of 10 chapters in CoStudy's OSHA 30 (Construction) bank, and it holds 20 of the bank's 300 multiple-choice questions — roughly 7% of the total. That proportion is not arbitrary: chapters follow the certifying body's published exam outline, and the number of questions in each is set by that domain's published weight, so the share of your practice time this chapter takes matches the share of the real exam it accounts for.

Studying by chapter is worth doing once you have a diagnostic score. A single overall percentage tells you whether you are close; it does not tell you which domain is dragging. Working a weak chapter in isolation, and re-testing it in isolation, is the fastest way to move a score that has stalled — and it is why the mock exams in CoStudy report by domain rather than as one number.

Free Introduction to OSHA practice questions

5 questions drawn from this chapter, with the full rationale shown — the controlling principle behind the right answer, and why each wrong option tempts and fails.

Whistleblower protection under OSHA is in:

  1. Section 11(c)
  2. Section 5(a)(1)
  3. Section 8
  4. Section 17

Answer: A — Section 11(c)

A) Correct. B) General Duty Clause. C) Inspections. D) Penalties.

OSHA poster requirement is:

  1. Optional
  2. Mandatory display in workplace listing worker rights
  3. For factories only
  4. Only on Mondays

Answer: B — Mandatory display in workplace listing worker rights

A/C/D) Wrong. B) Correct — 'It's the Law' poster.

Which standard set applies to a residential framing crew?

  1. 29 CFR 1910 General Industry
  2. 29 CFR 1928 Agriculture
  3. 29 CFR 1926 Construction
  4. 29 CFR 1915 Maritime

Answer: C — 29 CFR 1926 Construction

Wrong-standard trick. Construction work falls under 1926, not General Industry 1910.

  1. January 1 to March 31
  2. March 1 to May 31

  1. 8 hours
  2. 12 hours
  3. 24 hours
  4. 48 hours

Off-by-one threshold. C is correct. A applies only to fatalities.
