OSHA 30 test: what's actually on it and how to pass

Last updated 2026-07-09

What is the OSHA 30 test, exactly?

Most people searching for "OSHA 30 test" expect one big exam at the end of the course. That's not how it works.

OSHA's 30-hour outreach training program is delivered through OSHA-authorized trainers and online providers. The quizzes sit inside each topic module, not stacked into a single final. Finish the module on electrical hazards or scaffolding, and you take that module's quiz before moving on. The platform records your scores. Pass each quiz, complete the hours, and you get your OSHA 30-hour card.

OSHA itself does not write or standardize these quizzes. The agency sets the required topics and minimum hour allocations, but the actual test questions come from the course provider, whether that's a classroom instructor authorized through an OSHA Training Institute Education Center or an online platform authorized under OSHA's outreach program. That's why you'll see so many variations in practice materials online: there is no single official answer key. If a site claims to sell "official OSHA 30 test answers," treat it as a scam. ^[1]

For the OSHA 30 training side of things, including who must complete it and how the card works, that's a separate question from passing the quizzes. The two topics are closely related but distinct.

What topics do OSHA 30 test questions cover?

OSHA publishes the required content for both its Construction (29 CFR 1926) and General Industry (29 CFR 1910) outreach tracks. The topic lists below come from OSHA's Outreach Training Program Requirements, last revised in 2018. ^[1]

Construction track required topics:

Topic	Minimum Hours
Introduction to OSHA	2
Managing Safety & Health	2
OSHA Focus Four hazards (falls, struck-by, caught-in, electrocution)	7.5
Personal Protective Equipment	1
Health Hazards in Construction	2
Elective topics (trainer chooses)	15.5

General Industry track required topics:

Topic	Minimum Hours
Introduction to OSHA	2
Walking/Working Surfaces & Fall Protection	1
Electrical	1
Hazard Communication (29 CFR 1910.1200)	2
Personal Protective Equipment	2
Fire Protection & Prevention	1
Elective topics (trainer chooses)	21

The construction version weights the Focus Four heavily because those four hazard categories account for nearly 60% of construction worker deaths each year. ^[2] Expect multiple questions on fall protection standards (29 CFR 1926.502), scaffold safety, and electrical hazard recognition.

For general industry, hazard communication and lockout tagout get tested hard because violations in those areas make OSHA's top-10 most-cited standards list every single year. ^[3]

Elective topics vary by provider. Common ones include confined space entry, hearing conservation, ergonomics, forklift safety (see forklift certification), and machine guarding. Your quiz content reflects whatever electives your specific provider chose, which is another reason generic practice tests only get you so far.

What is the passing score for the OSHA 30 test?

Most authorized online providers require 70% on each module quiz to advance. Some set the bar at 75% or 80%. OSHA does not mandate a specific passing threshold in its outreach program requirements. The 70% figure is industry standard, not a federal rule. ^[1]

Fail a quiz and every authorized provider gives you at least one retake. Most allow unlimited retakes on the same quiz content, though some randomize the question order or pull from a question bank so you don't see the exact same questions twice. On most platforms you cannot skip a failed module and come back later. You pass it to proceed.

Here's the thing nobody tells you upfront. The quizzes for the OSHA rights and introduction modules are easy. The technical modules are where people trip: Fall Protection (29 CFR 1926.502), Scaffolding (29 CFR 1926.451), and Electrical Safety (29 CFR 1910.303 for general industry). Those involve specific numbers. Guardrail heights, maximum scaffold plank overhang distances, GFCI requirements near water. You have to actually learn the numbers, more than the concept behind them.

What do real OSHA 30 test questions look like?

The questions are provider-written, so no single source has the definitive set. But they follow predictable patterns. Here's a realistic breakdown by question type:

Regulation identification: "Under 29 CFR 1926.502, the top edge of a guardrail system must be at a height of _____ inches." (Answer: 42 inches, plus or minus 3 inches.) These test whether you know the specific standard, not the general idea. ^[4]

Hazard recognition scenarios: A short paragraph describes a worksite situation, and you pick which OSHA standard is violated or which hazard is present. These are the most practical and the most common.

Worker rights questions: What rights do workers have under the OSH Act? Can an employer fire a worker for filing a safety complaint? These come from the introduction to OSHA module and show up almost everywhere because the OSH Act's Section 11(c) anti-retaliation provision gets tested often. ^[5]

Definitions: What does SDS stand for? What is a "competent person" under OSHA? What's the difference between a "safety factor" and a "design factor" for scaffolding? Memorizing OSHA's exact definitions is worth more than people expect.

PPE selection: Given a described hazard (noise above 85 dBA, chemical splash risk, arc flash), which PPE is required? For OSHA training in general, PPE selection questions lean on hierarchy-of-controls logic.

The questions are multiple choice, almost universally, with four options. Real trick questions are rare. What's common is two plausible answers where one is more specific to the cited regulation. Reading the CFR section number in the question usually tells you which module you're in and which regulation applies.

How should you actually prepare for the OSHA 30 quizzes?

Practice tests help, but only if you use them right. A "practice OSHA 30 test" from a random PDF site shows you question formats and gives you exposure to regulatory numbers. It does not tell you what your specific provider will ask.

Here's what actually works.

Take notes during the modules. The quizzes pull straight from the module content. If the video or slide mentions a specific number (a height in feet, a decibel threshold, a weight rating), write it down. That number will likely show up in the quiz.

Use OSHA's own publications as study material. OSHA's pocket guides (the yellow and green ones on OSHA.gov) are free and cover the exact thresholds that show up in tests. The Construction Industry Pocket Guide and the General Industry QuickCard library are genuinely useful. ^[6]

If you want a practice OSHA 30 test to warm up, look for ones published by OSHA Training Institute Education Centers, not random quiz aggregator sites. The OTI centers are the authorized training arm of OSHA and their practice materials sit closer to the real thing. ^[7]

Don't buy "OSHA 30 test questions and answers PDF" files from commercial sites. They're almost always outdated, provider-specific at best, and sometimes flat wrong. The standards they reference may have changed. OSHA revised the Hazard Communication Standard (29 CFR 1910.1200) most recently in 2024 to align with GHS Revision 7, which means any PDF more than a year or two old may carry outdated HazCom answers. ^[8]

Pay special attention to the Focus Four (construction) or the top-cited standards (general industry). Those get tested heavily because they're the hazards that kill and injure the most workers. BLS data shows falls alone accounted for 395 construction fatalities in 2022, out of 1,069 total construction deaths that year. ^[2] Providers know that, and they weight their quizzes accordingly.

How long does the OSHA 30 online course take, and when do the tests happen?

The course must include at least 30 hours of instruction. OSHA's outreach program requirements cap online sessions at a certain length and prohibit finishing the full 30 hours in a single sitting. ^[1] Most authorized online platforms spread the content across multiple days, enforcing time limits per session.

Module quizzes appear right after the instruction content for that module ends. You typically cannot skip ahead to the quiz without watching or reading the module first, because the platform tracks time-on-task. Some platforms make you watch a set percentage of each video before the quiz unlocks.

For the OSHA 30-hour online course specifically, someone working through it part-time usually finishes in 5 to 10 days. Nobody realistically does it in one or two sittings under the current rules.

After you pass all module quizzes and complete the required hours, the provider submits your completion to OSHA's online tracking system. OSHA then mails your official 30-hour card (the plastic wallet card, not a certificate) within roughly 2 weeks for most providers, though the exact timeline varies.

What happens if you fail an OSHA 30 module quiz?

You retake it. That's it. No penalty, no disqualification, no record sent to OSHA. The quizzes exist to confirm you engaged with the material, not to weed people out.

Most online platforms let you retake a failed module quiz immediately. Some make you review the module content again before unlocking the retake. A few pull from a question bank, so the second attempt has different (though topically similar) questions. In practice, almost everyone who completes the course content passes the quizzes eventually.

The real failure mode is not failing a quiz. It's abandoning the course. Dropout rates run higher for online courses than in-person ones, usually because people underestimate the time commitment or lose momentum between sessions. Starting the course through an employer who requires completion, rather than self-enrolling, correlates with higher completion rates.

Abandon an online course and want to restart with a different provider? Most won't transfer your partial credit. You start from the beginning and pay the enrollment fee again.

Is there a final exam for the OSHA 30?

No. There is no cumulative final exam in OSHA's outreach program.

OSHA's Outreach Training Program Requirements document (updated 2018) does not require a final test. ^[1] Individual providers can add one if they want, but the major authorized online platforms don't. If you've heard otherwise, you may be thinking of the OSHA 30 trainer course (the 500-series courses that authorize someone to teach outreach training), which does have a heavier assessment component.

The absence of a final exam is also why searching for "OSHA 30 test answers" as though there's one key to find is a dead end. The answers you need depend entirely on which provider you're using and which modules they picked for the elective portion.

What's the difference between OSHA 10 and OSHA 30 test difficulty?

The OSHA 10 covers the same core topics but at a surface level. The OSHA 30 goes deeper on the same subjects and adds more module hours on specific hazard categories.

On the quiz side, OSHA 10 questions run more conceptual: "Which of the following is an example of a struck-by hazard?" OSHA 30 questions run more specific: "At what height above a lower level does 29 CFR 1926.502 require fall protection for workers on scaffolds?" (Answer: 10 feet for scaffolds under 1926.451, though the question's specific standard reference determines the right answer, so read carefully.)

OSHA 30 quizzes also cover management-level content: how to conduct a Job Hazard Analysis, what a safety and health management program should include, what an employer's recordkeeping obligations are under 29 CFR 1904. ^[9] OSHA 10 barely touches those. If you're an ops manager or site supervisor, the OSHA 30 content is closer to what you need day-to-day.

For context on the broader OSHA framework and what the agency enforces, the standards tested in OSHA 30 quizzes are real compliance requirements, more than course content.

Can you find legitimate OSHA 30 practice test questions for free?

Yes, a few genuinely useful sources exist.

OSHA's own website has compliance assistance resources, QuickCards, and e-tool quizzes on specific hazard topics. These aren't labeled "practice OSHA 30 tests," but they cover the exact material that shows up in quizzes. The eTool library at OSHA.gov includes interactive modules on scaffolding, electrical safety, and other high-frequency test topics. ^[6]

OSHA Training Institute Education Centers (there are 27 across the country, affiliated with universities and colleges) sometimes publish study guides and sample questions for their courses. Because they're the same organizations that deliver OSHA 500-series trainer courses, their materials are as close to authoritative as you'll find for free. ^[7]

CFR text itself is free at eCFR.gov. Reading the actual regulatory text for 29 CFR 1926.502 (fall protection systems criteria) takes about 20 minutes and beats any quiz aggregator site for test prep.

Some state plan agencies publish safety training resources with quiz-style content. California's Cal/OSHA Consultation Service and Washington's Department of Labor and Industries both run free online libraries. ^[10]

To build broader safety program context (the knowledge the OSHA 30 management modules test), SafetyFolio's safety program generator shows how the standards you're studying turn into actual written program requirements, without hiring a consultant to explain each one.

What to avoid: paid "OSHA 30 test questions and answers PDF" downloads. They're almost always scraped from old course content, may reflect superseded standards, and have zero quality control. Save the money.

Does passing the OSHA 30 test mean you're OSHA certified?

OSHA does not use the word "certified" for outreach training completions. The agency's own language is "completion" or "card holder." ^[1]

As OSHA states on its outreach program page: "The OSHA Outreach Training Program is not a certification program." Calling yourself "OSHA 30 certified" is technically inaccurate, though it shows up so often in job postings and contracts that the usage has become normal.

What the card actually proves: you completed 30 hours of OSHA-authorized outreach training and passed the provider's module quizzes. It does not prove competency on any specific task. It does not substitute for task-specific training required by OSHA standards (like confined space entry training under 29 CFR 1910.146 or respirator fit-testing under 29 CFR 1910.134). ^[11]

For many construction contracts, especially public projects, owners and general contractors require workers or supervisors to hold a 30-hour card as a contract condition. That's a contractual requirement, not an OSHA legal one. OSHA itself does not legally require the 30-hour card for most workers. Some states with OSHA State Plans have passed their own laws requiring it on public projects; New York, Nevada, and Connecticut have done this. ^[10]

The card is valid for life. No expiration date, no renewal requirement under OSHA's program rules, though individual employers or contracts may require refresher training at their own intervals. See osha 30 for the full breakdown of what the card covers and doesn't.

What topics trip people up most on the OSHA 30 quizzes?

Based on the content of the standards and what shows up consistently across practice materials, these are the areas where people answer wrong most often:

Specific numerical thresholds. Workers confuse the 4-foot general industry fall protection trigger (29 CFR 1910.28) with the 6-foot construction trigger (29 CFR 1926.502) and the 10-foot scaffolding trigger. These numbers are different by design, tied to different risk profiles. ^[4]

Hierarchy of controls. Questions ask you to rank controls in order: elimination, substitution, engineering controls, administrative controls, PPE. Most people know PPE is last but scramble the middle. Memorize the order.

Hazard Communication specifics. GHS-aligned SDSs have 16 sections in a set order. Questions ask which section covers first aid measures (Section 4) or physical/chemical properties (Section 9). Under the 2024 HazCom update, label requirements also changed. ^[8]

Lockout/Tagout sequence. 29 CFR 1910.147 requires a specific sequence for energy control procedures. Questions may present the steps out of order and ask which sequence is correct.

Recordkeeping thresholds. 29 CFR 1904 requires recording work-related injuries that meet certain criteria. What's recordable versus what's reportable (fatalities within 8 hours, hospitalizations within 24 hours) trips up a lot of people. ^[9] For a deeper look at documenting incidents, see incident report.

Rights and whistleblower protections. The OSH Act Section 11(c) prohibits retaliation against workers who exercise safety rights. Questions about what counts as illegal retaliation, what rights workers have to refuse unsafe work, and how to file a complaint all appear here. ^[5]

How do OSHA 30 test scores affect your card or your employer?

Your individual quiz scores are not reported to OSHA and do not appear on your card. The card simply says you completed 30 hours of outreach training. Whether you passed with 71% or 98% stays between you and the provider's platform.

Employers who pay for workers to complete the OSHA 30 sometimes ask providers for completion reports. Those reports confirm that specific workers finished the course, but they usually don't break down individual quiz scores unless the employer arranged for that reporting.

From an employer liability standpoint, having workers complete the OSHA 30 is one layer of an affirmative defense in OSHA inspections. If a citation gets issued and the employer can show workers were trained, it doesn't erase the citation but can move the penalty calculation. OSHA penalties for serious violations run up to $16,550 per violation as of 2024, and a good-faith training effort is a recognized penalty reduction factor. ^[12]

Building a written safety program that reflects the standards you're studying is the other half of that equation. That's where tools like SafetyFolio's safety program generator bridge the gap between knowing the OSHA 30 content and actually having documentation an inspector can review.

Frequently asked questions

How many questions are on the OSHA 30 test?

There is no single OSHA 30 test. Each module has its own quiz, typically 10 to 20 questions each. The total across the full 30-hour course varies by provider but usually falls between 100 and 200 questions spread across all modules. OSHA does not standardize question counts; the provider sets those.

What score do you need to pass the OSHA 30?

Most authorized providers require 70% on each module quiz. Some set the bar at 75% or 80%. OSHA does not mandate a specific passing score in its outreach program requirements. The 70% threshold is the de facto industry standard. If you fail a quiz, you can retake it; there is no limit to retakes at most providers.

Can you look up OSHA 30 test answers online?

You can find practice questions and regulatory text that match quiz content, but there is no single official answer key because each provider writes its own questions. Sites selling "OSHA 30 test answers" PDFs are selling outdated, unverified content. Your best sources are the actual CFR text, OSHA's free QuickCards on OSHA.gov, and materials from OSHA Training Institute Education Centers.

Is the OSHA 30 test the same for construction and general industry?

No. The construction track follows 29 CFR 1926 standards and emphasizes the Focus Four hazards: falls, struck-by, caught-in/between, and electrocution. The general industry track follows 29 CFR 1910 and covers hazard communication, electrical safety, machine guarding, and walking/working surfaces. The quizzes reflect these different regulatory chapters.

Do you have to take the OSHA 30 test in person?

No. OSHA's outreach program allows online delivery through authorized providers. Online courses have the same required topics and minimum hours as in-person ones. OSHA does limit how many hours can be completed per day in the online format to prevent people from rushing through. In-person courses at OSHA Training Institute Education Centers are also available.

How long do you have to complete the OSHA 30 once you start?

Most online providers give you 6 months to complete the course from the enrollment date. Some give up to a year. If you don't finish within the allowed window, you may have to restart or pay again. Check your provider's specific policy before enrolling, especially if you plan to spread the course over several weeks.

Does the OSHA 30 card expire?

No. OSHA's outreach training cards do not have an expiration date. They are valid for life under the program rules. Some employers and construction contracts impose their own refresher requirements (typically every 3 to 5 years), but that is a contractual condition, not an OSHA requirement.

What is the difference between the OSHA 30 and the OSHA 500 trainer course?

The OSHA 30 is a worker and supervisor-level outreach course. The OSHA 500 (for construction) and OSHA 501 (for general industry) are trainer authorization courses that qualify someone to deliver the 10- and 30-hour outreach programs to others. OSHA 500/501 courses are delivered through OSHA Training Institute Education Centers, require prerequisite experience, and involve heavier assessment.

Are there free OSHA 30 practice tests that are actually accurate?

OSHA.gov has free eTools and QuickCards covering topics like scaffolding, electrical safety, and hazard communication that mirror real quiz content. OSHA Training Institute Education Centers sometimes publish study guides. The CFR text at eCFR.gov is free and covers every number a quiz could ask about. Paid practice test PDFs from commercial sites are generally unreliable.

Does my employer need to verify I passed the OSHA 30 test?

Employers typically receive a completion report from the provider confirming you finished the course, but individual quiz scores are not sent to employers by default unless they specifically arranged for that. Your OSHA card itself just shows completion of the hours, not your quiz performance. Most employers only care that the card exists.

Can you fail out of the OSHA 30 course entirely?

Not really. Providers allow retakes on all module quizzes. The only way to fail to complete the course is to abandon it or run out of time within the provider's enrollment window. There's no penalty for multiple retake attempts. The bigger risk is paying for a course and not finishing it, which is more common than people expect, especially with online self-paced formats.

What CFR standards should I focus on for the OSHA 30 general industry quiz?

Prioritize 29 CFR 1910.1200 (Hazard Communication), 29 CFR 1910.147 (Lockout/Tagout), 29 CFR 1910.303 (Electrical), 29 CFR 1910.132 (PPE), and 29 CFR 1910.28 (Walking/Working Surfaces and fall protection). These standards consistently appear on OSHA's top-cited list and get heavy quiz coverage. OSHA's own citation data shows which standards are most enforced.

Do states with their own OSHA plans have different OSHA 30 tests?

State plan states (like California, Washington, and Michigan) run their own safety programs that are at least as strict as federal OSHA. Their outreach training still uses the federally authorized provider network and the same topic requirements. Some state-specific rules differ, and a good instructor or provider will note where state standards exceed federal ones. The card is federal, not state-specific.
