An OSHA 10 class is the entry-level workplace safety training developed by the Occupational Safety and Health Administration to introduce workers to job site hazards, employee rights, and employer responsibilities. The course runs exactly ten hours of instructional time, ends with a knowledge assessment, and results in a DOL (Department of Labor) wallet card that many states, municipalities, and general contractors require before a worker can legally step onto a construction or general industry site. The class is designed for entry-level personnel, not supervisors.
If you are searching for an osha 10 class, you are almost certainly responding to a job requirement. New York, Connecticut, Massachusetts, Missouri, New Hampshire, Nevada, Rhode Island, and dozens of large cities have laws that require an OSHA 10 card on public works projects exceeding a specified dollar threshold. Major general contractors like Turner, Skanska, AECOM, and Bechtel require it of every trade subcontractor regardless of state law, and most union apprenticeship programs build it into their first-year curriculum.
The class comes in two main flavors: OSHA 10 Construction and OSHA 10 General Industry. Construction covers framing, excavation, scaffolding, electrical, and the so-called Focus Four hazards (falls, electrocution, struck-by, caught-in/between) that cause roughly 60 percent of construction fatalities. General Industry covers manufacturing, warehousing, healthcare support, and similar non-construction settings, with greater emphasis on machine guarding, walking-working surfaces, and hazard communication.
You can take the class in person from an authorized OSHA outreach trainer, or fully online through one of the four OSHA-authorized online providers (ClickSafety, 360training, OSHA Education Center, and Summit Training Source). Online courses use a single sign-on portal, require timed module completion, and prevent fast-forwarding to enforce the full ten hours mandated by 29 CFR. The DOL card arrives by mail within two weeks of completion, though a printable temporary certificate is issued immediately.
Pricing is consistent across providers. Expect to pay between $59 and $89 for online OSHA 10 and $80 to $150 for an in-person seat. Employers often cover the cost, and several states allow employers to deduct the time spent in training from wages only under narrow conditions. The card itself is issued once and, under current OSHA outreach policy, does not technically expire, although many employers and states require refresher training every three to five years to keep skills current.
This guide walks you through everything you need to know before you enroll: the full topic list mandated by OSHA, how the test works, how long the card stays valid, what employers actually check, the difference between OSHA 10 and OSHA 30, and how to avoid the most common mistakes that get cards revoked. Use the table of contents to jump to the section that matters most for your situation, whether you are a brand-new apprentice or a journeyman switching trades.
Introduction to OSHA (2 hr), the Focus Four Hazards (4 hr) covering falls, electrocution, struck-by, and caught-in/between. These are non-negotiable and cannot be substituted by the trainer under any circumstance.
Trainer chooses at least two from a list including PPE, health hazards, materials handling, hand and power tools, and scaffolds. Minimum 30 minutes per elective topic to qualify for credit.
Remaining hours cover topics specific to the audience such as confined space, fire protection, ergonomics, or crystalline silica. Trainers tailor this block to the trades represented in the class.
Each module ends with a quiz of 5–15 questions. Online students must score at least 70% to advance. In-person students complete a paper assessment at the end of day two.
A cumulative 20–30 question exam tests recall across all modules. Online students get unlimited retakes on most platforms, but each retake resets the module timer.
The OSHA 10 class is aimed at entry-level workers, but the practical question of who must take it is determined by a patchwork of state laws, municipal ordinances, and private contract requirements rather than by OSHA itself. Federal OSHA does not mandate the card for any worker. The agency simply maintains the outreach program and accredits trainers. Every binding requirement you encounter on a job site comes from a state legislature, a city council, a project owner, or your general contractor's site-specific safety plan.
New York leads the country in enforcement. Under Local Law 196 in New York City, every construction worker on a job site requiring a permit must hold a Site Safety Training (SST) card, and the OSHA 10 is one of the qualifying components. Connecticut, under Public Act 06-175, requires OSHA 10 on any state-funded project over $100,000. Massachusetts requires it on all public works projects, and Missouri, Nevada, Rhode Island, and New Hampshire have similar laws with varying dollar thresholds and grace periods for new hires.
Outside the regulated states, private requirements dominate. The Associated General Contractors of America estimates that more than 80 percent of large general contractors require the card on every project regardless of jurisdiction. Many require it before a worker can even attend site orientation, which means showing up without a valid card can cost you a day's pay or your spot on the crew. Some refineries, chemical plants, and energy facilities go further and require OSHA 30, the supervisor-level version.
Union apprenticeship programs typically build OSHA 10 into the first-year curriculum, so apprentices receive it as part of their indenture rather than paying out of pocket. The carpenters, ironworkers, laborers, operating engineers, electricians, and plumbers all maintain in-house training centers where authorized trainers deliver the course alongside trade-specific skills. Non-union workers, especially open-shop contractors and independent specialty trades, typically pay for the course themselves or are reimbursed by their employer after completion.
General Industry students come from a different population. Warehouse associates at Amazon and Walmart, manufacturing employees at automotive suppliers, healthcare environmental services staff, hotel maintenance technicians, and food processing line workers commonly take the General Industry version. Many are sent by employers responding to incident-driven OSHA citations, since post-citation training is a routine abatement requirement. Others take it voluntarily to qualify for promotions or to add credentials when changing jobs.
One audience that should not take OSHA 10: foremen, superintendents, project managers, and anyone with supervisory authority over other workers. Those workers should take OSHA 30 instead, since the 30-hour course covers OSHA recordkeeping, accident investigation, and supervisor responsibilities that the 10-hour version omits entirely. Taking OSHA 10 when your job duties require OSHA 30 can leave both you and your employer exposed to citations during a compliance inspection.
Finally, the OSHA 10 is not a substitute for site-specific or task-specific training. Federal standards require separate training for fall protection competent persons, scaffold users, powered industrial truck operators, lockout/tagout authorized employees, confined space entrants, and respirator users. The OSHA 10 introduces these topics at an awareness level but does not authorize a worker to perform the regulated activity. Treat the card as a baseline credential, not a qualification.
Online OSHA 10 is delivered by four DOL-authorized providers using a locked-down learning management system. Modules play in sequence, the system tracks total seat time to the second, and you cannot skip past videos or knowledge checks. Most students finish in three to four sittings spread over several days because the platform enforces breaks and prevents binge completion. Mobile access is supported on all four providers but a desktop or laptop produces the most reliable experience.
Self-paced is the most popular format because it lets workers train on evenings, weekends, or rain days without losing a full shift. The trade-off is that you have no live instructor to answer questions, although every provider offers an email or chat help desk staffed by authorized trainers. Expect to pay $59 to $89 including the physical DOL card mailed to your address. Most providers will not ship internationally without an additional fee.
Live virtual classes meet on Zoom or a similar platform across two consecutive days, typically eight hours per day with built-in breaks. An authorized trainer presents slides, runs polls, breaks the class into small groups for case studies, and answers questions in real time. Webcams must remain on so the trainer can verify attendance and engagement, which OSHA requires as part of its 2020 temporary virtual delivery guidance that has since become permanent for outreach courses.
This format appeals to workers who learn better with a human instructor but cannot travel to a classroom. Pricing runs $90 to $140, slightly higher than self-paced but lower than in-person. Class sizes are capped at 25 students per trainer to maintain interaction quality. Cards are mailed within two weeks of the trainer submitting the class roster to OSHA, the same timeline as the other formats.
Traditional in-person delivery happens at union training centers, community colleges, vocational schools, and private safety training companies. The class runs across two consecutive days or four half-days. Hands-on demonstrations of harness inspection, ladder setup, and PPE donning give in-person students a tangible advantage that screen-based learning cannot replicate, particularly for visual or kinesthetic learners.
Cost ranges from $80 to $150 per seat, with discounts available for groups of ten or more. Employers often bring a trainer on-site for groups of fifteen or more, which makes per-student costs as low as $40. The downside is scheduling: you must commit to specific dates and locations, and missing any portion of the ten hours disqualifies you from receiving the card. Trainers are not permitted to give make-up time outside the scheduled class.
Employers, project owners, and inspectors can verify any OSHA 10 card by calling the OSHA Outreach Training Program office at 847-297-4810 and providing the trainer ID printed on the back of the card. Cards without a visible trainer number are almost always fraudulent and will be rejected at site orientation. Confirm yours is printed clearly before leaving the class or completing the online course.
The OSHA 10 class assessment is straightforward but trips up workers who underestimate it. Online courses build short quizzes into every module — typically five to fifteen questions drawn from a bank of several hundred. You must score 70 percent or higher to advance to the next module. If you fail, the platform sends you back to review the module material and lets you retake the quiz, usually with unlimited attempts. The clock keeps running, so failed attempts add time to your overall completion.
The final assessment is a cumulative test of twenty to thirty multiple choice questions covering every module you completed. Passing score is again 70 percent. Most platforms allow two or three attempts on the final before requiring you to restart specific modules. Questions are pulled from a randomized bank, so even if you fail and retake, you will see a different mix the second time around. Reading the OSHA Outreach Program Procedures document before testing helps because it explains exactly what trainers must teach.
In-person classes use a different assessment model. Trainers can choose to give a single end-of-course exam, weave knowledge checks into each module, or use a combination of methods. The standard end-of-course exam in classroom settings is also twenty to thirty questions, and the 70 percent threshold still applies. A student who fails the in-person exam can usually retest with the trainer the same day, but a second failure requires repeating the course in full.
Question style is predictable. Expect scenario-based stems describing a job site situation followed by four answer choices, only one of which fully addresses the OSHA requirement. The exam is not trying to trick you with regulation citations or obscure standard numbers. Questions test whether you can recognize the most common hazards, identify the correct hierarchy of controls, name your rights under the OSH Act, and know who has the authority to stop work on a job site.
The single most-tested topic across both Construction and General Industry tracks is fall protection. Falls cause more construction deaths than any other hazard, so OSHA mandates substantial classroom time on the subject and weights the assessment accordingly. Memorize the six-foot trigger height in construction, the four-foot trigger in general industry, the requirement to provide guardrails, safety nets, or personal fall arrest systems, and the difference between body belts (no longer permitted for fall arrest) and full-body harnesses.
The second most-tested cluster is hazard communication. Know the elements of a Safety Data Sheet, the order and contents of the sixteen SDS sections, the meaning of GHS pictograms, the difference between a hazard category and a hazard class, and your right to access SDS files at your workplace. Hazard communication appears on virtually every OSHA 10 final exam regardless of trainer or platform because it applies to every workplace covered by the standard.
Finally, do not skip the worker rights material. Several questions on every exam test your knowledge of the right to file a confidential complaint with OSHA, the right to access exposure and medical records, the right to be free from retaliation under Section 11(c), and the prohibition against employer-paid PPE deductions. Workers who study only the technical hazard material and skip the rights modules consistently miss easy points and end up retaking the final.
Once you finish the OSHA 10 class and receive your DOL wallet card, the question becomes how to keep it valid and how to build on it. The card itself does not carry a federal expiration date. The OSHA Outreach Training Program Procedures document explicitly states that cards do not expire, and the agency does not maintain a renewal mechanism. A 2008 card is technically as valid as a 2026 card in the eyes of federal OSHA. That fact surprises many workers and is repeatedly tested on assessments.
State and employer policies, however, frequently override that federal default. New York City requires SST card renewal every five years, with refresher training counting toward the renewal hours. Connecticut and Missouri do not mandate renewal but several large general contractors require any worker with a card older than five years to retake the course before being allowed on site. Always confirm with your employer or the project owner before assuming an older card is still acceptable.
The natural next credential is OSHA 30. The 30-hour course covers all of the OSHA 10 material at greater depth, adds substantial new content on supervisor responsibilities, accident investigation, OSHA recordkeeping under Part 1904, and the OSHA inspection process, and qualifies the holder to act as a competent person for many job site decisions. Most foremen, superintendents, safety coordinators, and project managers carry the 30. Workers who plan to move into supervision should plan on completing it within their first three years on the tools.
Beyond OSHA 30, specialty credentials open up trade-specific advancement. Scaffold competent person training, fall protection competent person training, OSHA 510 for prospective construction industry trainers, OSHA 500 for instructors, the BCSP Construction Health and Safety Technician, and the Certified Safety Professional all build on the OSHA 10 foundation. Many workers find that the discipline they developed completing OSHA 10 — sitting through ten hours of regulation-heavy material — translates directly to success in these longer programs.
If you ever lose your wallet card, you can request a replacement from the trainer who issued it for up to five years after the class. Bring your card number, the date of training, and a government ID. Most trainers charge $15 to $35 for the replacement. After five years, the trainer is not required to keep records and may not be able to verify your completion, which is why photographing both sides of the card the day you receive it is the single most important administrative step you can take.
Workers who travel between states or change employers frequently should be aware that some employers accept only cards issued by their preferred provider. While this practice has no basis in federal regulation — any authorized DOL card is legally equivalent — it does happen, particularly with large industrial clients who maintain enterprise contracts with specific training vendors. If you find yourself in this situation, ask whether your existing card satisfies the contractual requirement before paying for a duplicate course.
Finally, treat the OSHA 10 as the beginning of a continuous learning habit, not a one-time hurdle. The safety field changes constantly as OSHA issues new standards, NIOSH publishes new research, and case law reshapes employer obligations. Subscribe to the OSHA Quick Takes newsletter, follow your trade association's safety alerts, and review the OSHA standards at least annually for any rule changes affecting your work. Workers who do this routinely become the go-to safety voice on their crews and accelerate their careers as a result.
The practical advice for passing the OSHA 10 class on the first attempt is simpler than most students expect, but it requires discipline. Block off your training time on a calendar, treat it like a paid shift, and silence your phone for the duration of each module. Online providers detect window switching and idle time and will pause your seat-time counter if you wander off, which can extend a ten-hour course into fifteen or twenty hours of elapsed time. The fastest finishers commit to two five-hour sessions and never deviate.
Take notes by hand even if you are training online. Writing reinforces memory in ways that highlighting on a screen never matches. Keep a single sheet of paper for definitions (competent person, qualified person, authorized employee, employer, employee), a second sheet for trigger heights and exposure limits, and a third for citations of the most-referenced standards. By the time you finish, you should have a three-page personal study guide you can review before the final assessment in fifteen minutes.
Use the free practice questions on this site before you sit for the final. The questions are written to mirror the style and difficulty of the actual OSHA 10 assessment, and reviewing the explanations clarifies misconceptions that the official course material can leave ambiguous. Workers who run through at least two practice sets before the final exam pass at roughly twice the rate of workers who attempt the exam cold, according to data we collect from our quiz platform.
If English is your second language, take advantage of the Spanish-language version of OSHA 10. All four authorized online providers offer Spanish, and many union training centers do as well. The DOL card you receive is fully equivalent. There is no asterisk or notation indicating a language variant, and no employer in the United States can lawfully reject a card on that basis. Cards in additional languages including Polish, Mandarin, and Vietnamese are available through select providers.
Plan for the small administrative tasks at the end. The platform will ask you to confirm your mailing address, complete a brief survey for OSHA, and download a temporary certificate. Do all of this immediately while you are still logged in. Students who close the browser window before finishing the post-completion steps sometimes find their card stuck in limbo because the trainer never received final confirmation. A two-minute delay at the end of the class can save you a two-week support ticket later.
Once your physical card arrives, photograph the front and back, save the images to your phone and a cloud backup, and consider laminating the card itself. Wallets and tool belts destroy unprotected cards quickly, and any new employer can ask to inspect the original at hiring. A clean, legible card communicates professionalism in the same way a clean tool bag does. Workers who treat the card carelessly often end up paying for an avoidable replacement within a year.
The final tip is to keep your trainer's contact information. The authorized trainer who issued your card is your verification source for the rest of your career, your replacement-card provider for the next five years, and often your gateway to upper-level outreach courses like OSHA 30 or OSHA 510. Many workers find that staying in touch with the trainer who delivered their first safety class opens doors to additional certifications, instructor opportunities, and even job leads at safety-conscious employers in their region.
