An OSHA 10 card is the wallet-sized credential the Department of Labor issues after a worker completes the 10-hour Outreach Training Program. The card proves you sat through the required safety modules, passed the module quizzes, and met the federal baseline for hazard awareness on a construction site, general industry floor, maritime terminal, or disaster cleanup zone.
People mix up the card with the certification itself. They are not the same. The course is what you take. The card is what you get. The card is the physical (or now mostly digital) artifact you hand to a foreman, post on a job-site bulletin board, or scan into a contractor portal. Without that card in hand, most general contractors will not even let you through the gate.
You may have heard the card called the "OSHA wallet card," the "DOL 10-hour card," or just the "blue card" (general industry cards are usually blue, construction cards are usually green, though colors vary by Outreach Training Institute). The federal program is the same. Issuing authorities differ, and yes, that matters when you go to verify one.
This guide walks through what the card looks like, when it shows up after class, how long it stays valid, how to replace one you lost, and why the document still functions as a hiring filter in 2026 even though the training itself can be done in an afternoon. Test your readiness with our OSHA 10 certification resources before you sit for the final exam.
The card proves one specific thing: the named worker completed the OSHA Outreach Training Program at the 10-hour level under an authorized trainer registered with an OSHA Training Institute Education Center. That is the entire scope. It is not a license. It is not a certification in any specific piece of equipment. It does not authorize you to operate a forklift, work at heights, or handle hazardous waste beyond awareness level.
Here is the part people miss. OSHA itself does not require the card for most jobs. The federal agency wrote 29 CFR 1926 and 29 CFR 1910 without ever mentioning the 10-hour Outreach card as a mandate. State laws, project specs, union agreements, and general contractor policy made the card a de facto requirement. Four states actually wrote it into statute: New York, Connecticut, Nevada, and Missouri. The rest treat it as best practice.
That doesn't make the card optional. Try walking onto a Turner or Skanska job site in Manhattan without a green card visible on your hard hat. You will be politely escorted back to the gate. The card is checked. Subcontractors get fined when their workers don't have one. Some general contractors run weekly audits and pull cards into a digital roster scanned by QR codes.
When you finish the course your trainer issues two things. A paper completion certificate, printed immediately, valid for proof during the gap period. And the actual plastic card, mailed by the OSHA Training Institute Education Center within two weeks (sometimes six). The certificate covers you while you wait. Do not throw it away.
Treat both documents as official. The plastic card is the long-term proof, but the paper certificate is what gets you onto the job site during weeks one through four. Make a photocopy of the certificate the day you receive it and keep one copy in your truck, one in your locker, and a phone photo saved in your cloud storage.
An authentic OSHA 10 card carries a fixed set of data fields. If a card is missing any of these, treat it as suspicious. The federal program standardized the format in 2009 after a wave of counterfeit cards started circulating in the New York City construction market.
The front of the card shows the worker's full legal name, the course completion date, the trainer's name, the trainer's OSHA Outreach Trainer ID number, and the issuing OSHA Training Institute Education Center logo. The back of the card carries the OSHA Outreach Training Program disclaimer (the line that says completion does not satisfy the requirements of 29 CFR 1910 or 1926), the unique card serial number, and sometimes a QR code for digital verification.
That serial number matters. Authorized trainers report every issued card to OSHA within 60 days. A general contractor with verification access can scan or type the serial into the OSHA Outreach Trainer Verification Portal and confirm the card is real. Counterfeit cards usually fail at the serial check first. They get the format right, they print the disclaimer, but the serial doesn't exist in the federal roster.
Color coding is informal but consistent. Construction Industry Outreach is green. General Industry Outreach is blue. Maritime is white. Disaster Site Worker is yellow. Some training centers ignore the color convention and print everything blue. The federal program does not actually mandate color. Field foremen still rely on it for quick triage.
Green card covers 29 CFR 1926. Required on most state and federal construction sites. Topics include fall protection, electrical safety, struck-by hazards, scaffolds, and PPE.
Blue card covers 29 CFR 1910. Used in manufacturing, warehousing, healthcare facility, and retail work. Topics include lockout/tagout, machine guarding, hazcom, emergency action, and ergonomics.
White card covers shipyard work (1915), marine terminals (1917), and longshoring (1918). Required on US shipyards, port terminals, and many commercial fishing operations.
Yellow card. Awareness-level training for cleanup and recovery operations after hurricanes, tornadoes, structural collapse, or hazardous spills. Built post-9/11 for World Trade Center recovery work.
Federal answer: forever. OSHA does not place an expiration date on the Outreach card. The card you earned in 2008 is, in OSHA's eyes, still valid in 2026. The federal program treats the training as a one-time awareness intervention. Refresh it if you want, but no statute forces you to.
State answer: it depends. Four states overrode the federal default. New York Labor Law 220-h requires renewal every five years for workers on public works projects valued over $250,000. Connecticut public projects follow the same five-year clock. Missouri public works projects mirror the New York rule. Nevada has the strictest enforcement and requires a five-year renewal across all covered construction work, not just public projects.
Project answer: also depends. Many general contractors set their own expiration. Turner Construction, AECOM, Bechtel, and a handful of others enforce a three- or five-year refresh internally even on sites where state law would let you skate. Union agreements sometimes write the refresh into the collective bargaining agreement.
Practical answer: if your card is more than five years old, retake the class. The cost is low, the time is one workday, and you avoid the awkward moment where a foreman pulls you off a crew because his project spec says cards must be under five years old. Many workers keep an updated OSHA 10 certification on file simply to clear that gate.
Green card. Built for workers on construction job sites. Topics include fall protection, electrical safety, struck-by and caught-between hazards, scaffolding, ladders, excavations, hand and power tools, personal protective equipment, and health hazards in construction. Required by law in NY, CT, NV, MO for covered projects. The dominant card type in the US labor market, with more than 1.2 million construction cards issued annually.
Blue card. Built for manufacturing, warehousing, healthcare, retail, and similar non-construction work. Topics include walking and working surfaces, exit routes, emergency action plans, fire protection, machine guarding, lockout/tagout, hazardous materials, and bloodborne pathogens. Less common state mandate, more common employer mandate. Becoming standard in Amazon-style fulfillment centers and food production facilities.
White card. Covers shipyard employment under 29 CFR 1915, marine terminals under 1917, longshoring under 1918. Smaller workforce, more specialized topics. Confined spaces in shipyards, fall hazards over water, and machinery hazards specific to vessel work get heavy emphasis. ILWU and ILA unions strongly encourage the card for all member workers.
Yellow card. Created after the World Trade Center cleanup made clear that disaster site work is its own discipline. Covers respiratory protection in dusty environments, decontamination, traumatic incident stress, and the unique structural collapse hazards rescue and recovery crews face. FEMA recovery contractors and state emergency management contractors are increasingly requiring it.
The card arrives in one of three ways depending on who delivered your training. Live in-person classes hand you a paper certificate the day you finish and mail the plastic card from the trainer's home office within two weeks. Online providers like ClickSafety, 360training, or OSHA Education Center generate a digital certificate immediately and mail the plastic card from the issuing OTIEC within four to six weeks.
The plastic card is mailed via standard USPS first class. There is no tracking number. If you move during the gap period, you may never see the card. The provider will reprint a replacement, but you have to ask, and there is often a $15 to $30 replacement fee.
Some providers now offer digital cards. CareerSafe and a few of the larger Outreach trainers will email you a PDF version with a QR code that links to the verification portal. The digital card is accepted by some general contractors and rejected by others. New York City Department of Buildings still requires a physical card displayed on the hard hat under Local Law 196. Bring both.
If the card never arrives, the issue is almost always one of three things: your provider did not actually report the completion to OSHA, the OTIEC sent it to an old address, or the USPS lost it. Contact your trainer first, then the OTIEC listed on your completion certificate, then OSHA Region office only if both fail to respond within 90 days.
Lost cards are common. The plastic is thin, wallets get washed, work pants go through the laundry, and most workers never make a photocopy. You can get a replacement, but the rules depend on when you took the class and who issued the original.
If the card was issued less than five years ago, contact your original trainer first. They keep the records and can request a duplicate from the OTIEC. Cost ranges from free (if the provider is generous) to about $30. Turnaround is usually two to four weeks.
If the trainer is unreachable, contact the OTIEC directly. The OTIEC name should appear on your completion certificate or in any email confirmations from the class. Each OTIEC keeps roster records for at least five years per OSHA Outreach Training Program Requirements.
If the card is more than five years old, your trainer has retired, and the OTIEC purged the records, you are out of luck. OSHA does not maintain a master federal database of all Outreach cards ever issued. The 60-day reporting requirement only started capturing meaningful data after 2018. Your only path forward is retaking the 10-hour class. Refresh your knowledge with our safety training review materials before you sit for the new card.
Plenty of confusion lives here. Federal OSHA never mandated the card. State legislatures and employers did. The result is a patchwork that catches new workers off guard.
New York requires it under Labor Law 220-h for any worker on a public works project valued at $250,000 or more, expanded under Local Law 196 to cover nearly all construction sites in the five boroughs of New York City regardless of project value. Connecticut requires it for state and municipal public works contracts. Missouri requires it for public works valued at $75,000 or more. Nevada is the most aggressive, requiring it for almost any construction work, public or private, with limited exceptions for very small projects.
Outside those four states, the card is employer-driven. General contractors on large commercial, healthcare, and federal projects almost universally require it. Subcontractors who do not enforce it among their own crews get reverse-charged for compliance costs or kicked off the project. Even small residential remodelers in markets like Massachusetts, Florida, and California are now requiring crews to carry the card because insurance carriers offer lower workers' compensation rates for documented safety training.
If you are unsure whether you need one, ask your employer or the general contractor you are bidding under. Do not guess. Showing up at a Manhattan job site without a green card visible on your hard hat will end your shift before it starts. A quick review of the what does OSHA cover material can also help you understand which industries fall under the federal mandate.
The OSHA 30 is the supervisor-level version. Triple the hours, same Outreach Training Program structure, deeper coverage of every topic. The 10 is meant for entry-level workers who need hazard awareness. The 30 is meant for foremen, safety officers, and anyone with responsibility for a crew.
On most union projects in New York City, the 30 is required for supervisors and the 10 is required for everyone else. The cards look similar but carry different markings. Confuse them and you will be removed from a position you are not authorized to hold. Workers planning to step into leadership often skip the 10 entirely and go straight to the 30. Both are administered through the same OTIEC network and the same Outreach Trainer system.
A useful rule of thumb: if you swing a hammer, you need a 10. If you supervise the people swinging hammers, you need a 30. If you operate specific equipment, you may also need equipment-specific OSHA-compliant training that goes beyond either Outreach card. The card is a baseline, not a ceiling. Many workers pair the 10 with our OSHA forklift certification path or our practice test resources to build a stronger safety credential portfolio.
The card is not a piece of paper that makes you safe. The training behind it is. The 10 hours of Outreach content cover the hazards that kill construction workers and general industry workers year after year — falls, electrocution, struck-by events, caught-between hazards, machine guarding failures, lockout/tagout violations, respiratory exposure. Knowing what those hazards look like before you walk onto a site has saved lives. The card just proves you have that knowledge.
Treat the card like you treat your driver license. Carry it. Make a photocopy and store it in your truck or your locker. Snap a photo of the front and back and save it to your phone. If a foreman asks for it during a tier audit, you want to have it in hand within thirty seconds, not after a frantic search through three jackets and a glove box.
If you do not have one yet, take the class. The cost is modest, the time investment is one day, and the access it unlocks to better-paying union and commercial work pays back the registration fee in a single shift. If your card is expired under your state or project rules, refresh it. The world of construction in 2026 runs on documentation, and the OSHA 10 card is the most basic piece of paperwork the industry runs on.
One more practical note. If you are bidding on public work in any of the four mandatory states, do the math on your whole crew before you commit. Crew of fifteen with no current cards at $80 per worker is $1,200 plus a day of lost productivity per worker. Build that into your bid. The general contractors already have. So have your competitors. Skipping the card is not a way to save money; it is a way to lose the job before you start it.
Workers who treat the card as a one-time checkbox tend to underperform on the modules. The questions on the final exam are not designed to fail anyone, but the modules on fall protection and hazard communication trip up people who skim. Slow down on those two. Read the slides. Take the practice questions in our review bank seriously. The 70 percent module pass requirement is real, and trainers do not award the card to workers who guess their way through.
A few miscellaneous things worth knowing. Veterans receive no special discount on the course, despite a common myth circulating on job sites. The card cannot be transferred between workers, even between family members with the same last name. Each card is tied to a unique federal serial number and a verified identity check at enrollment. Most authorized providers now require a government-issued photo ID upload before they issue the card, a practice that became standard after the 2014 fraud cases.
If you are an employer reading this, build a simple internal roster. A spreadsheet with worker name, card serial number, issue date, industry type, and a scanned photo of the front and back of each card is enough for most general contractor audits. Reviewing the roster monthly, flagging anyone within twelve months of a state-mandated five-year refresh, and budgeting the refresh course into your next payroll cycle will keep your crew on-site and your bid competitive.
