OSHA 10 vs OSHA 30: Which Card Does Your Crew Need?

October 8, 2026

OSHA 10 vs OSHA 30 is the first decision in almost every outreach class we scope, and most employers frame it the wrong way. The useful question is not which card is better. It is which card fits the job each person on your roster actually does, and, before that, whether the work is construction or general industry. Get the track or the length wrong and you either pull a crew off the floor for twenty hours of training nobody asked for, or you send a foreman to a prequalification desk with a card the owner will not accept.

This guide lays out what the two courses share, what the extra twenty hours actually contain under OSHA’s current Outreach Training Program procedures, how to match each role to a card, and the scheduling rules that decide how many days your people are away from production. If you already know what you need, send us your headcount and site details and we will scope an on-site class around your shifts.

OSHA 10 vs OSHA 30 at a glance

Both courses come from the same voluntary program, both are taught by an OSHA-authorized outreach trainer, and both end with a Department of Labor student course completion card. The differences are depth, audience and time. The table below uses the program requirements and the 2024 construction and general industry procedures that OSHA publishes for authorized trainers.

OSHA revises these documents from time to time. Treat the numbers as the current rule set, and check the Outreach Training Program Requirements before you build a schedule around any one of them.

Who OSHA says each course is for

OSHA’s own program overview describes the 10-hour program as “primarily intended for entry level workers” and the 30-hour program as giving workers with some safety responsibility a greater depth and variety of training. That second phrase does a lot of work, and it is broader than a job title.

Some safety responsibility covers the obvious roles: foremen, superintendents, shift supervisors, safety coordinators. It also covers people whose title says nothing about safety. A lead hand who runs the morning pre-task plan has it. So does a maintenance technician who isolates energy so other people can work on a machine, a warehouse lead who signs off on the daily truck inspections, and a crew chief who decides whether the wind is too high to keep working. Each of them makes decisions that put other people’s exposure in their hands.

The reverse is also true. A journeyman with twenty years in the trade and no responsibility for anyone else’s work is a reasonable 10-hour candidate, unless a contract says otherwise. Experience is not the test. Authority over other people’s exposure is.

Neither course is a standards class. OSHA’s procedures say outreach training should emphasize hazard identification, avoidance, control and prevention rather than the regulations themselves. The 30-hour construction procedures go further and state that the 30-hour class is not equivalent to OSHA #510, the standards course trainers take at an OSHA Training Institute Education Center. If a role needs to read and apply the standards, the 30-hour card is a starting point, not the destination.

What the extra 20 hours actually buy

The difference between the two courses is not the same slides shown more slowly. The 30-hour adds a management module, deepens several required topics, and grows the elective block five- to sixfold, which is where a good trainer fits the class to your site.

Construction

The 10-hour construction course requires six hours of fixed content: one hour of Introduction to OSHA (workers’ rights, employer responsibilities, how to file a complaint), four hours on the Focus Four hazards, thirty minutes on personal protective equipment and thirty minutes on health hazards in construction. Falls must take at least an hour and a half of the Focus Four time, because OSHA ties most construction fatalities to fall hazards; electrocution, struck-by and caught-in or between get at least thirty minutes each. Two more hours go to at least two elective topics, and the last two hours are optional time the trainer can use to expand on any of it.

The 30-hour construction course requires fourteen hours of fixed content. Introduction to OSHA stays at one hour. Managing Safety and Health adds two hours on injury and illness prevention programs, job-site inspections, accident investigation, running safety meetings and supervisory communication. The Focus Four grows to six hours, PPE and health hazards each grow to two hours, and stairways and ladders gets a dedicated hour. The elective block is at least twelve hours across at least six topics, and the optional block is four hours.

The construction elective list includes concrete and masonry, permit-required confined spaces, cranes and hoists, excavations, fire protection, materials handling, motor vehicles and mechanized equipment, powered industrial vehicles, scaffolds, steel erection, hand and power tools, welding and cutting, and safety and health programs. The 30-hour list adds Foundations for Safety Leadership, which runs at least two and a half hours and is aimed squarely at the people who direct crews.

General industry

The 10-hour general industry course also requires six hours, but spreads them differently: one hour each on Introduction to OSHA, walking and working surfaces including fall protection, exit routes and emergency and fire prevention plans, electrical, personal protective equipment, and hazard communication. At least two hours go to two or more electives, and two hours are optional.

The 30-hour general industry course requires twelve hours: Introduction to OSHA, two hours of Managing Safety and Health, walking and working surfaces, two hours on exit routes and emergency planning, two hours on electrical, PPE, two hours on materials handling, and hazard communication. The elective block is at least ten hours across at least five topics, and the optional block is eight hours.

General industry electives include hazardous materials, permit-required confined spaces, lockout/tagout, machine guarding, welding and cutting, an introduction to industrial hygiene, bloodborne pathogens, ergonomics, fall protection, safety and health programs and powered industrial vehicles.

Why the elective block matters more than the total

For an employer, the elective and optional hours are the most valuable part of either course, because that is where the class stops being generic. A food plant with heavy lockout exposure and a high forklift count should spend its 30-hour electives on lockout/tagout, machine guarding and powered industrial vehicles. A site contractor should spend them on excavations, cranes, scaffolds and struck-by exposure from equipment. When we teach on site, we pick the electives with you before the class, using your equipment list and your incident history, and we use your own floor for the examples. A 30-hour class with sixteen hours of electives aimed at someone else’s hazards is a missed opportunity.

Construction or general industry: pick the track first

The length decision gets the attention, but the track decision causes more wasted training. Outreach cards are industry-specific. A construction 30-hour card is not a general industry card, and a plant supervisor who sat the construction course learned about trench boxes and steel erection instead of machine guarding and lockout.

OSHA’s general industry rules define construction work in 29 CFR 1910.12(b) as work for construction, alteration and/or repair, including painting and decorating. That gives a workable test:

• Manufacturing, warehousing and distribution, food processing, utilities operations, healthcare support and most plant maintenance belong on the general industry track. Our OSHA 10-hour general industry and OSHA 30-hour general industry classes cover those workforces.
• General contractors, specialty subcontractors, renovation crews, site work and anyone building, altering or repairing structures belong on the construction track. Those crews take the OSHA 10-hour construction or OSHA 30-hour construction course.
• Mixed teams, such as an in-house maintenance department that also runs capital projects, should follow the bulk of the work, or the card the customer or owner names. When the contract specifies the track, the contract wins.

The most common mistake we see is a manufacturer buying construction 30-hour cards for production supervisors because a staffing agency or a former employer told them “OSHA 30” without a track. The supervisors get four days of training, and very little of it matches the hazards they manage.

Matching the card to the role

There is no federal rule that assigns a card to a job title. What follows is how employers who think it through usually sort their rosters, based on the outreach program’s own description of the two audiences. Your contracts, your customers and any state law that applies to you come first.

Two practical notes. First, train for the role a person is about to hold, not just the one they hold today; if you are promoting three leads next quarter, put them in the 30-hour now. Second, do not let the card stand in for the training the job actually requires, which is covered further down.

Where the requirement really comes from

OSHA does not require either card. The Outreach Training Program FAQ says plainly that the courses are voluntary, that some states, municipalities, employers and unions have mandated them, and that whoever mandates the training decides what it will accept. In practice the requirement arrives from three directions.

State and local law

A handful of states and cities have written outreach cards into law. Nevada is the clearest example of the 10-versus-30 split: under NRS Chapter 618, a construction worker must present an OSHA-10 card within 15 days of being hired and a construction supervisor must present an OSHA-30 card, or the employer must suspend or terminate them. Nevada applies the same workers-take-10, supervisors-take-30 pattern to live entertainment, convention and cannabis workplaces, each with its own deadlines and, in some of those sections, a five-year card life. Other states and some cities have their own rules, usually tied to public works or to specific job sites. Read the statute or the bid documents; do not rely on a summary, including this one.

Contracts and owners

Most requirements we see come from general contractor prequalification packets and owner specifications: everyone on site holds a 10, every foreman and above holds a 30, cards no older than a set number of years. Federal work can add its own layer; contracts that cite the U.S. Army Corps of Engineers safety manual, EM 385-1-1, set training requirements for the Site Safety and Health Officer that include 30-hour outreach coursework, so read the edition your contract cites. These are contractual terms, so they vary job to job, and the strictest customer you serve usually ends up setting your company standard.

Your own program

The third source is you. Plenty of manufacturers with no customer mandate use the general industry 10 as a baseline for every new hire and the 30 for every supervisor, because it gives the whole workforce the same vocabulary for hazards. That is a sound policy, provided it sits on top of the standard-specific training rather than replacing it.

Can a 10-hour card become a 30-hour card?

Yes, under narrow conditions. OSHA’s FAQ allows a trainer to give a student who completed a 10-hour course twenty more hours and issue a 30-hour card, provided the same trainer conducts all of the training, everything from the start of the 10-hour class to the end of the 30-hour class is completed within six months, and the student surrenders the 10-hour card so the trainer can return it to the issuing Authorizing Training Organization. OSHA requires the surrender so that nobody appears to hold forty hours of training they did not receive.

The planning lesson is simple. If you are training a new crew with the 10-hour and expect to move some of them into lead roles soon, book the same trainer, keep the follow-on inside the six-month window, and collect the 10-hour cards before the upgrade class. Outside those conditions the worker sits the full 30-hour course.

The calendar math

The program requirements set hard limits on how fast the hours can be delivered, and those limits decide how long your people are off the floor.

• Daily limit. No more than 7.5 student contact hours per calendar day. That makes the 10-hour a two-day class at minimum and the 30-hour a four-day class at minimum.
• Session length. A single training session can run no more than ten consecutive hours including breaks, meals, attendance and any optional test.
• Breaks. At least a ten-minute break after every two consecutive contact hours, and a meal period of at least thirty minutes in any session longer than six hours. Break time does not count as instruction.
• Splitting the class. The trainer can deliver the course in segments of at least thirty minutes over days, weeks or months, as long as the whole class is completed within 180 calendar days of its start.
• Class size. At least three students and no more than forty for in-person classes, unless the authorizing organization grants an exception.
• Testing. Optional. Test time never counts toward the required hours.
• Cards. The trainer must get completion cards to students within 90 calendar days of the class end date.

For an employer, the segment rule is the useful one. A plant that cannot lose a whole shift can run the 10-hour across several partial days, and a contractor can spread the 30-hour across two lighter weeks instead of four straight days. We build the schedule around your production plan; the only fixed points are the daily limit, the breaks and the 180-day window.

What neither card does

This is the part most often missed, and it is the part a compliance officer will ask about. OSHA states on its Outreach Training Program page that outreach training does not fulfill an employer’s training obligations under specific OSHA standards. Neither card is a certification or a license, and OSHA does not assign continuing education units to outreach classes.

The standards that require training still require it, whatever card a worker holds:

• Forklift and other powered industrial truck operators need formal instruction, practical training and an evaluation of their performance under 29 CFR 1910.178(l). See our forklift operator training and the guide to forklift refresher training.
• Construction workers exposed to fall hazards need training from a competent person under 29 CFR 1926.503. A Focus Four hour on falls is awareness, not that program. Our fall protection training covers it.
• Authorized and affected employees need energy-control training under 29 CFR 1910.147(c)(7); see lockout/tagout training.
• Employees exposed to hazardous chemicals need information and training under 29 CFR 1910.1200(h); see hazard communication training.
• Competent person duties for excavation, scaffolds and similar work come from the employer’s designation, not from a card. Our guide to who qualifies as a competent person explains the test, and competent person training builds the knowledge behind it.

OSHA maintains a full list of standards with training requirements in Publication 2254. A sensible program uses the outreach card as the shared baseline and then maps each role to the standard-specific training it needs.

Online classes or a live trainer on your site

OSHA’s requirements name standard in-person classroom instruction as the preferred delivery method. Self-paced online outreach courses are only legitimate through the online providers OSHA has accepted; individual trainers are not allowed to run self-paced remote classes at all. Live video classes are permitted with conditions, including advance notice to the authorizing organization and a smaller class size unless a proctor is present.

Online works for an individual who needs a card quickly. For a crew, a live instructor on your site usually serves the employer better, for three reasons. The trainer can aim the elective hours at your equipment and your incident history. Workers can ask about the forklift, the mixer or the trench they will be standing next to tomorrow. And the trainer can see who is following and who is not, which a self-paced module cannot.

Language matters too. The requirements say trainers must teach in a language the students understand, or use a qualified interpreter, and class time grows to allow for the interpretation. Tell us the language mix on your crew when you ask for a quote so we can plan the days correctly.

Whoever you hire, verify the trainer before the class. OSHA tells students to ask to see the trainer’s current authorized trainer card, which shows the expiration date and the authorizing training organization; trainers must renew with an update course every four years, and a lapsed trainer cannot issue cards. Our construction classes are taught by an OSHA 500-authorized trainer and our general industry classes by an authorized OSHA 501 outreach trainer, and the cards are issued through the OSHA Training Institute Education Center that authorizes our trainers. You can read more about how we run these classes on our OSHA outreach training page.

Records worth keeping

OSHA does not keep records of outreach classes, and it does not verify individual cards. The trainer keeps class records for five years, and a lost card can be replaced only once and only if the class was within the last five years. That puts the burden on the employer. For every class, keep the roster with each student’s name, the industry track, 10 or 30, the class start and end dates, the trainer’s name, a copy of the trainer’s authorization card and the name of the authorizing organization. With that record, a worker who loses a card in year three gets a replacement in days instead of a retake.

Track the date the card was issued, too. The card itself does not expire under the federal program, but customers and some state rules impose their own refresh intervals. Our guide to whether OSHA 30 expires walks through where those intervals come from.

Common questions

Is OSHA 30 better than OSHA 10?

It is longer and deeper, not better. The 30-hour is built for people with some safety responsibility; the 10-hour is built for awareness. Putting an entry-level worker through thirty hours costs production time without changing what that worker is allowed to decide, and putting a supervisor through only ten leaves out the management content written for them.

Do workers need OSHA 10 before taking OSHA 30?

No. The program requirements do not make the 10-hour a prerequisite for the 30-hour. A supervisor can go straight into the 30-hour course. The only link between the two is the optional upgrade path, which requires the same trainer and a six-month window.

How long does each course take?

At least ten contact hours over at least two calendar days for the 10-hour, and at least thirty contact hours over at least four calendar days for the 30-hour, plus breaks and meals. The class can also be split into shorter segments as long as it finishes within 180 days of its start.

Does an OSHA 10 or OSHA 30 card expire?

Not under the federal program. Construction and general industry completion cards carry no expiration date. Contracts, owners and some state laws set their own refresh intervals, so check the requirement you are trying to meet.

Is the OSHA 30 the same as the OSHA 510 or 511 course?

No. OSHA #510 and #511 are standards courses taught at OSHA Training Institute Education Centers, and they are prerequisites for people who want to become authorized outreach trainers. The outreach 30-hour is a hazard-based course delivered by authorized trainers, and OSHA’s construction procedures state that it is not equivalent to #510.

Can one class cover both construction and general industry?

No. They are separate programs with separate topic requirements and separate cards. If your workforce splits across both, the usual answer is two classes, often run back to back on the same site.

Is an online OSHA 30 card as good as one from a live class?

The card is the same if the online provider is on OSHA’s accepted list. Whether the training is as useful for your crew is a different question, and it is why most employers with a group choose a live class aimed at their own hazards.

Match the card to the role, then to the contract

Start with the track, construction or general industry, based on the work itself. Sort your roster by who carries responsibility for other people’s exposure. Then hold that list up against every contract, owner specification and state rule you work under, and let the strictest one set the floor. When the roster is sorted, tell us how many people need each card and where your site is, and we will bring the class to you, schedule it around your production, and aim the elective hours at the hazards your crews actually face.
