OSHA offers dozens of certifications, but the number depends on how you count them
OSHA (the Occupational Safety and Health Administration) does not issue a single master count of certifications because the agency itself does not certify workers. Instead, OSHA approves training providers and course curricula, and those providers issue certificates to people who complete the training. The most commonly recognized OSHA certifications fall into a few main categories: the 10-hour and 30-hour construction cards, the 10-hour and 30-hour general industry cards, and specialized certifications in areas like fall protection, confined space, and forklift operation. Beyond those, authorized training providers offer hundreds of additional courses on specific hazards and industries.
The confusion exists because "OSHA certification" is shorthand for "a certificate from a training provider that OSHA has approved." OSHA itself does not test you or hand you a card. A third-party training organization runs the course, administers the exam, and issues the certificate if you pass. This is why you might see the same course offered by different providers under slightly different names—they are all teaching OSHA-approved content, but the certificate itself comes from the provider, not from OSHA.
Key Takeaways
- OSHA does not issue certificates; approved training providers do, so there is no single official count of how many certifications exist.
- The 10-hour and 30-hour cards (construction and general industry) are the most widely recognized and required by many employers and job sites.
- Specialized certifications in fall protection, confined space entry, forklift operation, and other hazards are offered by hundreds of approved providers.
- The certificate you receive is valid for the duration stated by your training provider, typically three to five years, and does not expire automatically under OSHA rules.
The two most common OSHA cards: 10-hour and 30-hour
The 10-hour and 30-hour cards are the entry point for most workers. The 10-hour card covers basic safety awareness and takes one or two days to complete. The 30-hour card goes deeper into hazard recognition, safety planning, and regulatory requirements, and usually takes three to five days. Both come in two versions: one for construction work and one for general industry (manufacturing, warehousing, healthcare, and other non-construction settings).
Many construction sites require workers to have at least a 10-hour card before they can enter the job. Some employers and union apprenticeships require the 30-hour card. The card itself does not expire under OSHA rules, but individual employers or job sites may set their own renewal timelines—some ask for refresher training every three years, others every five years. Check with your employer or the specific job site to know what they require.
Specialized certifications beyond the basic cards
Once you have a basic card, you can pursue certifications in specific hazards or equipment. Common ones include fall protection (for workers at heights), confined space entry (for tanks, silos, and enclosed areas), scaffolding safety, electrical safety, hazard communication, and bloodborne pathogens. There are also equipment-specific certifications like forklift operation, aerial lift operation, and crane safety. Each of these is offered by multiple approved providers, so the exact number of courses available varies by region and provider.
These specialized courses typically take a few hours to a full day and result in a certificate that shows you have completed training in that specific area. Employers in industries like construction, manufacturing, and healthcare often require one or more of these certifications as a condition of employment. The content and length vary by provider, so two forklift certifications from different organizations might not be identical, though both will cover OSHA-approved material.
How to find out which certifications your job requires
Your employer or the job site supervisor is the best source for this information. Ask directly: "What OSHA certifications do I need to work here?" or "What certifications are required for this position?" They can tell you whether you need a 10-hour or 30-hour card, which specialized certifications matter for your role, and whether they have a preferred training provider.
If you are looking for work and want to make yourself more marketable, the 10-hour card is the safest starting point. It is widely recognized across industries and job sites, takes minimal time, and costs between $50 and $150 depending on the provider. From there, you can add specialized certifications based on the types of jobs you are pursuing.
Why the number of certifications keeps growing
OSHA regularly approves new training courses as industries evolve and new hazards emerge. For example, certifications around COVID-19 safety, heat illness prevention, and mental health in the workplace have been added in recent years. Additionally, individual states sometimes create their own occupational safety programs (called "state plan states") and may offer certifications that go beyond the federal OSHA standard. This means the total number of available certifications is not fixed—it changes as new courses are approved and old ones are retired.
The takeaway is that there is no single answer to "how many OSHA certifications are there" because OSHA is not a certifying body itself. What matters for your job is knowing which specific certifications your employer requires and finding an approved provider to complete that training.
How to verify a training provider is actually approved by OSHA
OSHA maintains a list of approved training providers on its website, organized by state and course type. Before you pay for a course, search the OSHA Training Institute Education and Research Centers (TIEC) directory or ask the provider for their OSHA approval number. Legitimate providers will have this information readily available and will not pressure you to enroll when ready.
Be cautious of providers who claim to offer "OSHA certification" without being on the approved list, or who promise that their certificate will may provide you a job. A legitimate OSHA-approved certificate shows you have completed training in a specific safety topic—it does not may provide employment, and OSHA does not endorse any particular provider as "the best."
Frequently Asked Questions
Do OSHA certifications expire?
OSHA itself does not set expiration dates for certificates. However, your employer or job site may require you to renew your training every three to five years. Check your certificate and ask your employer about their renewal policy. Some industries have stricter timelines than others.
Can I take an OSHA course online?
Yes, many approved providers offer online 10-hour and 30-hour courses. However, some specialized courses (like forklift operation) may require hands-on, in-person training. Check with the provider to confirm whether the course you need is available online and whether it meets your employer's requirements.
What is the difference between a 10-hour and 30-hour OSHA card?
The 10-hour card covers basic safety awareness and hazard recognition in a day or two. The 30-hour card goes deeper into safety planning, regulatory requirements, and management responsibilities, and takes three to five days. Many employers prefer or require the 30-hour card for supervisory or safety-sensitive roles.
How much does an OSHA certification cost?
A 10-hour card typically costs $50 to $150, and a 30-hour card costs $150 to $400, depending on the provider and whether the course is in-person or online. Some employers cover the cost for their workers. Specialized certifications usually cost $50 to $200 each.
Is an OSHA certificate the same as a license?
No. A certificate shows you completed training in a safety topic. A license is issued by a government agency and allows you to perform a specific job (like electrical work or plumbing). Some jobs require both a license and OSHA training, while others require only one or the other.
