OSHA 30 refresher training: what's actually required and when

Last updated 2026-07-09

Does OSHA require a 30-hour refresher course?

No. OSHA's Outreach Training Program, which is the official program behind the 10-hour and 30-hour cards, does not set a federal expiration date or mandatory refresher schedule for either card. The Department of Labor's Outreach Training Program requirements say workers who complete the program receive a wallet card, but that card has no printed expiration. ^[1]

This surprises a lot of people, and it causes real confusion on job sites. The 30-hour card you earned in 2017 is technically still valid under federal OSHA rules today.

That said, "technically valid under federal rules" and "acceptable to your employer, state, or general contractor" are two very different things. If you stop reading here and assume you're fine forever, you'll eventually show up to a job site and get sent home.

Why do so many people think the OSHA 30 card expires?

The confusion comes from three places that all operate on top of the federal baseline.

First, some state OSHA plans and state labor laws have layered on mandatory refresher requirements. New York Local Law 196, for example, requires construction workers in New York City to complete a site safety training card, and that program has renewal requirements tied to OSHA Outreach completion. ^[2] Other states like Nevada and Connecticut have their own construction training mandates.

Second, many large general contractors and union agreements independently require workers to hold a current 30-hour card renewed every 3 to 5 years. That's a contractual obligation, not a federal one. When a laborer gets turned away at a gate for an expired card, it's usually the owner's project safety plan or a union CBA doing the work, not 29 CFR 1926.

Third, some OSHA-authorized trainers and training providers market their courses as "renewing" a card that never technically expired in the first place. That framing sells courses, and it isn't wrong to retrain, but it overstates the legal obligation.

The practical takeaway: check your specific state, your specific contract, and your specific job site requirements before assuming anything.

Which industries or states actually mandate an OSHA 30 refresher?

Here's where it gets specific. A handful of jurisdictions have moved beyond federal minimums and require documented refresher training by law.

Jurisdiction / Rule	Who It Covers	Refresher Requirement
New York City Local Law 196 (2017)	Most construction workers on NYC permitted sites	40-hour SST card with renewal every 4 years [2]
Nevada Revised Statutes 618	Public works contractors	OSHA 10 or 30 completion required; renewal varies by contract
Connecticut Public Act 19-1 (highway construction)	State highway project workers	10-hour minimum; some contracts require 30-hour renewal
Massachusetts OSHA (State Plan)	General industry and construction	No fixed refresher rule, but training must remain "current" under 454 CMR 10
California (Cal/OSHA)	Construction, general industry	No OSHA Outreach mandate, but 8 CCR §1509 requires an Injury and Illness Prevention Program with training tied to job hazards, which many satisfy through 30-hour programs

Union agreements in the building trades (Carpenters, Ironworkers, Laborers) often set 3- or 5-year renewal windows in collective bargaining agreements, and those obligations are real even where state law is silent.

If you're outside those jurisdictions and not bound by a CBA, the federal baseline applies: no mandatory refresher. That doesn't mean it's a good idea to skip one. It just means you're making a risk management call, not breaking a law. ^[3]

How often should you retrain even if it's not required?

Most safety professionals land on a 3-to-5-year window as the sensible default, and there's logic behind it beyond just keeping a card current.

OSHA standards change. The 29 CFR 1926 construction standards have been amended multiple times since 2010, including major updates to scaffolding, confined space in construction (1926.1200 series, effective 2015), and beryllium exposure limits. ^[4] Someone who took a 30-hour course in 2012 may never have been trained on rules that are now actively enforced.

Worker behavior drifts. Research on safety training retention generally shows measurable skill decay within 6 to 12 months of training without reinforcement. A study published in the journal Safety Science found that "retention of safety knowledge declines significantly one year post-training in the absence of refresher activities." ^[5] That's not a reason to retrain every year, but it is a reason not to treat the original card as a permanent pass.

Your role changes. A carpenter who later moves into a foreman or superintendent role faces a genuinely different hazard profile. The supervisory focus of the OSHA 30 course (it's designed for workers who direct others, more than workers doing tasks) only matters if the content stays current with what that person is actually supervising.

A reasonable default: plan for a refresher every 5 years, sooner if you change industries, take on a new supervisory role, or work in a state or on a project with explicit requirements.

What does an OSHA 30 refresher course actually cover?

There's no separate "OSHA 30 refresher" curriculum recognized by OSHA's Outreach Training Program. What most trainers sell as a refresher is one of two things: a full repeat of the original 30-hour course, or a shorter focused course built around changed standards and high-incident topics that doesn't result in a new card.

If you need a new wallet card for contractual or state compliance purposes, you need to complete a full authorized 30-hour course again through an OSHA-authorized trainer. There's no OSHA-sanctioned abbreviated refresher that produces a new official card. ^[1]

For the full osha 30 training curriculum, construction courses (29 CFR 1926) typically run 30 contact hours and cover fall protection, scaffolding, electrical safety, personal protective equipment, struck-by and caught-in hazards, and health hazards. General industry courses (29 CFR 1910) cover lockout/tagout, hazard communication, machine guarding, fire protection, and similar topics.

For workers who want to fill knowledge gaps without earning a new card, shorter focused courses, toolbox talks, and annual OSHA-required training on specific standards (like lockout tagout under 1910.147 or hazard communication under 1910.1200) can serve that function. Some of those have their own annual or periodic retrain requirements regardless of 30-hour card status.

Is online OSHA 30 refresher training accepted?

This is where things got complicated fast. OSHA suspended all online-only 10-hour and 30-hour Outreach training in 2020 and has not fully reinstated it at the time of writing. As of late 2023, OSHA authorized a hybrid model for some courses, but the exact status of online delivery varies by Authorized Training Organization (ATO) and topic area. ^[6]

Before you register for any course marketed as an osha 30 hour online course, verify directly with the provider that their delivery format is currently authorized by OSHA's Outreach Training Program. OSHA's website maintains a searchable list of authorized trainers and ATOs. An online course from a non-authorized provider will not produce a legitimate OSHA wallet card.

For state-mandated refreshers like New York City's SST program, online completion options are specifically defined in the law. NYC's Department of Buildings maintains the list of approved providers. If your requirement comes from a state law rather than federal OSHA, check with the state agency, more than the federal program.

Bottom line: the legitimacy of online delivery depends entirely on the authorization status of the specific provider and course at the time you take it.

What's the cost of an OSHA 30 refresher?

Costs vary considerably depending on format, provider, and location.

In-person instruction from an OSHA-authorized trainer runs roughly $150 to $350 per person for a full 30-hour course, based on prevailing market rates. Group rates at a worksite can drop the per-person cost to $100 or below if you have 10 or more trainees. ^[7]

Online courses, where currently authorized, have historically run $129 to $200 per person through major providers. State-specific programs like New York's SST may add administrative fees on top of the training cost.

Lost wage costs are the bigger number most small businesses undercount. Thirty hours of instruction for a $25/hour worker is $750 in direct wage cost before you account for any productivity impact. For a crew of 10, the all-in cost of a scheduled refresher can easily run $8,000 to $12,000 once you factor instructor fees, materials, and wages.

Set against that: the average OSHA penalty for a serious violation was $15,625 in fiscal year 2023, and willful violations averaged $156,259. ^[8] A training gap that contributes to an injury or a citation quickly eclipses the cost of keeping workers current.

Does an OSHA 30 card expire or can you just keep the old one?

The federal OSHA wallet card has no printed expiration date. OSHA does not have a database that invalidates older cards. ^[1] If your only concern is a federal OSHA inspection, producing a 10-year-old card doesn't automatically trigger a violation.

But general contractors and project owners have started checking card issuance dates, and many will not accept a card older than 3 or 5 years regardless of what federal rules say. This is an industry norm, not a federal requirement, and it's been hardening over the past decade as large owners have written it into their project safety requirements.

The honest answer is that the card "expires" whenever your specific employer, GC, union, or state says it does. Some people have been working off cards from 2008 with no problem. Others have been turned away from a job site because their card was issued more than 36 months ago. Know your specific situation.

If you're not sure what applies to you, the safest move is to document the requirement in writing, ideally from the contract or project safety plan, before investing in a refresher. That documentation also matters for your own incident report records if anything ever goes wrong and you need to demonstrate worker qualification.

How does OSHA 30 refresher training fit into your written safety program?

This is the piece small businesses most often get backwards. They track the card and forget to track the requirement.

A written safety program should document three things related to OSHA 30: who is required to hold a current card as a condition of their role, what "current" means for your organization (date threshold), and how you verify and record completion. Without that written structure, you're managing training on memory and good intentions.

For supervisors and foremen in construction, a policy requiring a current OSHA 30 (renewed within 5 years) as a condition of the supervisory role is defensible, practical, and signals to regulators and clients that your training program has structure. OSHA's training requirements across specific standards (fall protection under 29 CFR 1926.503, hazard communication under 29 CFR 1910.1200) require documented training, and general 30-hour completion helps demonstrate good faith on those topic areas but doesn't replace them. ^[3]

If your written program doesn't exist yet or you're starting from scratch, SafetyFolio's safety program generator can produce a compliant written program in about 15 minutes, including training documentation requirements specific to your industry. That won't replace the training itself, but it gives you the written framework OSHA expects to see.

For topics covered in the 30-hour curriculum that have their own standalone retrain requirements, like lockout tagout procedures under 1910.147(c)(7)(iii) or forklift certification under 1910.178(l), those specific standards drive the training interval, not the 30-hour card. Don't conflate them.

What should you look for in a legitimate OSHA 30 refresher provider?

A few things separate a real authorized course from a certificate mill.

First, the trainer must be an OSHA-authorized trainer for the relevant industry area (construction or general industry). OSHA-authorized trainers receive their authorization through an OSHA Training Institute Education Center. You can verify trainer authorization through OSHA.gov. ^[9] If a provider can't give you the trainer's name and authorization number, that's a red flag.

Second, the course must meet the minimum contact hour requirements: 30 hours total, with required topic areas and minimum times on each. OSHA has published guidance on the required topic distribution. Courses that promise to compress 30 hours into a weekend are cutting time somewhere, and some of those cuts may affect card legitimacy.

Third, completion should result in an official DOL wallet card, issued through the OSHA Outreach Training Program, typically within 2 weeks of completion. The card should show the trainer's authorization number and the completion date. A generic certificate of completion without that card is not an OSHA Outreach card.

OSHA also funds the Susan Harwood Training Grant program, which pays for free or low-cost safety training aimed at small employers and hard-to-reach workers. Those grants have produced some strong materials worth a look before you pay for anything. ^[10]

What other training renewals should you track alongside an OSHA 30 refresher?

The OSHA 30 covers many topics, but plenty of them carry their own mandatory periodic training requirements under specific CFR standards. A worker can hold a current OSHA 30 card and still be out of compliance on topic-specific retraining if those aren't tracked separately.

Here are some of the most common periodic retraining obligations in construction and general industry:

Standard	Topic	Retraining Trigger
29 CFR 1910.178(l)	Powered industrial trucks (forklifts)	Every 3 years, or after observed unsafe operation [11]
29 CFR 1910.134(k)	Respiratory protection	Annually
29 CFR 1910.1200	Hazard communication	When new hazards are introduced
29 CFR 1926.503	Fall protection (construction)	When there is reason to believe worker lacks understanding
29 CFR 1910.147(c)(7)	Lockout/tagout	When procedures change, or employee observed not following
29 CFR 1910.157(g)	Portable fire extinguishers	Annually

None of those are satisfied by holding an OSHA 30 card. They're separate standards with separate requirements. If you build a training matrix, treat the OSHA 30 as one line item in a larger grid, not as a substitute for topic-specific compliance. A gap in forklift retraining, for instance, is a 29 CFR 1910.178 violation regardless of what cards a worker holds. ^[11]

How do you document OSHA 30 refresher training correctly?

Documentation is where many small businesses create their own problems. They complete the training and lose the records.

At minimum, keep a copy of every wallet card (front and back) and a training log that records the employee name, card number, trainer name and authorization number, completion date, and course type (construction vs. general industry). If you're in a state with mandatory refresher requirements, keep the documentation long enough to cover any audit window the state specifies. New York City, for example, requires workers to carry or have accessible proof of their SST card on the job site. ^[2]

OSHA's recordkeeping standards under 29 CFR 1904 don't specifically require employers to retain OSHA Outreach card documentation, but OSHA inspectors can and do request training records during inspections, and a training record is your primary defense against a "lack of training" citation under the General Duty Clause (Section 5(a)(1) of the OSH Act). ^[12]

Store records somewhere more durable than a filing cabinet nobody knows about. A shared drive, an HR system, or even a dedicated folder in your project management tool works if someone is accountable for keeping it current. The format matters less than the habit.

Frequently asked questions

Does the OSHA 30 card expire?

Officially, no. Federal OSHA's Outreach Training Program does not print an expiration date on wallet cards and has no mechanism to invalidate older ones. In practice, many general contractors, unions, and state programs treat cards older than 3 to 5 years as expired for their own compliance purposes. Whether your card is "expired" depends on the specific requirements of your employer, project, or state.

How often should you renew your OSHA 30 card?

There's no federal mandate, but every 3 to 5 years is the industry norm and what most safety professionals recommend. The 5-year window reflects both the pace of standard changes and the general research on safety knowledge retention. If you work in New York City construction, the local law sets a 4-year renewal cycle for the required Site Safety Training card.

Is there a shorter OSHA 30 refresher course that counts for a new card?

No. OSHA's Outreach Training Program does not have an official abbreviated refresher that produces a new wallet card. If you need a new official card, you need to complete the full 30-hour course again through an authorized trainer. Shorter courses can update your knowledge but won't result in a new DOL card.

Can you take an OSHA 30 refresher online?

It depends on current authorization status. OSHA suspended online-only 30-hour courses in 2020 and has allowed limited hybrid delivery since then. Before registering for any online course, verify directly with the provider that their format is currently authorized by OSHA's Outreach Training Program. Unauthorized online courses don't produce a valid DOL wallet card.

What states require OSHA 30 refresher training by law?

New York City's Local Law 196 requires a 40-hour Site Safety Training card with 4-year renewals, which incorporates OSHA Outreach training. Several other states and municipalities have related training mandates. Outside of specific state or local laws, there's no federal requirement. Check your state labor department for current requirements in your jurisdiction.

Does OSHA 30 cover forklift certification?

The OSHA 30 curriculum includes powered industrial truck topics, but completion does not satisfy the specific forklift operator certification requirement under 29 CFR 1910.178(l). That standard requires hands-on evaluation by a qualified person and retraining every 3 years or after observed unsafe operation. The 30-hour card and forklift certification are separate requirements.

What's the difference between OSHA 10 and OSHA 30 refresher requirements?

Both the OSHA 10 and OSHA 30 are part of the same federal Outreach Training Program and carry the same absence of a federal expiration rule. The 30-hour course is longer and aimed at supervisors and workers with safety responsibilities. Where state laws or contracts require renewals, they typically specify which card and what interval, so check the specific requirement for your role.

How much does an OSHA 30 refresher course cost?

In-person instruction through an authorized trainer typically runs $150 to $350 per person for the full 30-hour course, with group discounts sometimes dropping per-person costs below $100. Online courses, where authorized, have run $129 to $200. The bigger cost for employers is often lost wage time: 30 hours for a $25/hour worker is $750 in wages alone, before instructor fees.

Can my employer require OSHA 30 refresher training even if OSHA doesn't?

Yes. Employers can set training requirements stricter than federal minimums, and most OSHA standards explicitly allow this. If your employer's written safety program or your employment contract requires a current OSHA 30, that's a binding workplace requirement regardless of what federal OSHA mandates. General contractors can also make it a condition of site access.

Does completing an OSHA 30 refresher protect my company from citations?

It helps demonstrate good faith and a functioning safety program, which matters in penalty mitigation. But it doesn't immunize you from citations. OSHA can still cite you under topic-specific standards if workers aren't trained on the specific hazards covered by those standards, even if they hold a current 30-hour card. Training documentation for specific standards matters separately.

What training records do I need to keep for OSHA 30?

Keep a copy of the wallet card (front and back), a training log with employee name, card number, trainer authorization number, completion date, and course type. OSHA's 1904 recordkeeping standards don't specifically require Outreach card retention, but inspectors can request training records, and those records are your primary defense against a General Duty Clause training citation.

Is OSHA 30 required for all construction workers?

No federal standard universally requires OSHA 30 for all construction workers. Some state laws, local ordinances, and project-specific requirements do mandate it for certain roles. New York City Local Law 196 comes closest to a broad mandate for construction workers on permitted sites. Outside of those specific requirements, it's a widely adopted best practice, not a universal legal obligation.

What happens if an OSHA inspector finds workers without current training?

If workers lack training required by a specific OSHA standard, the employer faces a citation and penalty under that standard. For the 2023 fiscal year, the average serious violation penalty was $15,625. Willful violations averaged $156,259. If the gap involves a standard that explicitly requires retraining, like respiratory protection or lockout/tagout, that's a distinct violation separate from any 30-hour card question.
