For most entry-level construction workers, OSHA-10 is the most commonly required credential, with CPR certification close behind. If your work involves driving heavy vehicles, you'll also need a CDL. If you're looking to enter the electrical trade, the IBEW apprenticeship is the most structured path in. Not every certification applies to every role, though — here's what each one actually covers and who needs it.
OSHA-10 is a 10-hour entry-level safety training program delivered by OSHA-authorized trainers. It covers hazard recognition, fall protection, personal protective equipment, electrical safety, and other jobsite fundamentals. Once completed, you receive an OSHA course completion card that does not expire and does not require renewal.
OSHA-30 is the 30-hour version, designed for workers with supervisory or safety responsibilities. If you're just starting out as a field worker rather than a foreman or site supervisor, OSHA-10 is typically sufficient.
At the federal level, the OSHA Outreach Training Program is voluntary. OSHA's official guidance makes clear that it is not a mandatory requirement under any OSHA standard. In practice, however, many states, municipalities, jobsites, and general contractors require OSHA-10 as a condition of employment, particularly on public works projects and large contracts. Check the specific job posting before assuming either way.
OSHA-10 can be completed in person or online through an OSHA-authorized training provider. Fees vary by provider and typically range from $30 to $80.
CPR certification is the second most commonly required credential in construction, after OSHA-10. Most contractors list it as a pre-hire requirement, and certain roles involving work at height or in confined spaces may have additional regulatory obligations tied to it.
The two main issuing bodies are the American Heart Association (AHA) and the American Red Cross, both of which are widely accepted. The AHA's Heartsaver series is designed for people without a medical background and is specifically noted as meeting OSHA training requirements. According to AHA's official guidance, course completion cards are valid for two years.
Courses typically run four to eight hours and are available through AHA-authorized training centers, with blended online-plus-hands-on options as well. Since renewal is required every two years, it's worth aligning your renewal date with your employment cycle so it doesn't lapse mid-project.
A Commercial Driver's License (CDL) is a federal requirement for operating heavy commercial vehicles in the United States. According to the Federal Motor Carrier Safety Administration (FMCSA), CDLs are issued in three classes. Class A covers combination vehicles with a gross vehicle weight rating over 26,001 pounds, such as tractor-trailers, and also authorizes the holder to operate Class B and C vehicles. Class B covers single vehicles over 26,001 pounds, including large dump trucks and concrete mixers. Class C applies to specific vehicle types, primarily those designed to carry 16 or more passengers or those transporting hazardous materials.
In construction, Class A is the most common requirement. Linemen typically operate bucket trucks and equipment-hauling trailers, making Class A standard for that role. Whether a specific position requires a CDL is usually stated clearly in the job listing.
The process starts with passing a written knowledge test to obtain a Commercial Learner's Permit (CLP), followed by required driving training and a road skills test. As of February 2022, first-time Class A and Class B applicants must also complete entry-level driver training through a provider listed on the FMCSA Training Provider Registry.
The IBEW (International Brotherhood of Electrical Workers) apprenticeship is one of the most recognized pathways into the electrical trade. The program is administered jointly by the IBEW and the National Electrical Contractors Association (NECA) through the Electrical Training Alliance.
It's a five-year earn-while-you-learn program. Apprentices work alongside licensed journeymen on real job sites, completing approximately 8,000 hours of on-the-job training alongside required classroom instruction. The program is fully funded by the IBEW and NECA — there are no tuition costs and no student debt. Upon completion, apprentices receive a nationally recognized Journeyman card.
Applications are submitted through your local Joint Apprenticeship Training Committee (JATC), which you can find through the Electrical Training Alliance website. The process typically includes submitting an application, taking the IBEW aptitude test (algebra and reading comprehension, with a passing score of 4 out of 9), and completing an oral interview. Application windows and available slots vary by local chapter, so it's worth checking your local JATC's schedule in advance.
These four credentials don't all apply to every worker. General laborers typically need OSHA-10 and CPR as a baseline, with additional requirements depending on the project. Linemen and telecom construction workers need both of those plus a Class A CDL as standard, and the IBEW apprenticeship is the recommended entry path for anyone looking to build a long-term career in the electrical trade. Heavy equipment operators should expect CDL (usually Class A or B) to be the core requirement, with OSHA-10 also expected. Anyone entering the electrical trade should look at the IBEW program first — OSHA-10 and CPR training are typically covered as part of the apprenticeship itself.
If you're just getting started, OSHA-10 is the highest-return first step. It takes about two days and costs under $100, and it's the fastest way to show a contractor you're ready to work.
Is OSHA-10 required by law?
At the federal level, no. OSHA's official guidance states that the Outreach Training Program is voluntary and does not fulfill any mandatory training requirement under OSHA standards. That said, many states, cities, and individual jobsites require OSHA-10 as a condition of employment, particularly on government and large general contractor projects. Requirements vary by location and employer.
How long does it take to get OSHA-10?
The course is 10 hours in total, typically split across two days. Online courses can be completed in segments at your own pace, as long as you finish within 180 days of the course start date.
Can I get a construction job without any certifications?
Yes, but having certifications makes a meaningful difference in both hiring and pay. Many smaller contractors will hire without them and require you to complete OSHA-10 within a set period after starting. If you're looking for your first job, OSHA-10 is the quickest way to demonstrate you're ready for the jobsite.
How much does OSHA-10 cost?
Costs vary by provider. Online courses typically range from $30 to $80. OSHA maintains an official list of authorized online training providers — it's worth using one from that list to make sure your completion card is valid.
How often does CPR certification expire?
According to the American Heart Association, course completion cards are valid for two years from the date of issue. The American Red Cross certification follows the same renewal schedule.
Starting from your apprenticeship, getting into the habit of photographing your work is something that pays off over time. Before-and-after conditions, material placement, daily progress — these jobsite photos become useful when reporting to a foreman, supporting project handover, or resolving disputes over completed work.
Timemark is a field photo documentation tool that embeds a verified timestamp, GPS coordinates, and tamper-proof metadata at the moment of capture. There's no manual sorting after the fact — each photo carries a complete record of where, when, and what was done.
For team projects, Timemark's Teamspace automatically collects photos from all team members into a shared project space, organized by date and location, with the option to export as a report when needed. Start for free.
Timemark is a jobsite photo documentation app with timestamp, GPS geotag, and on-site notes. With Teamspace, field teams can automatically collect, organize, search, and export job photos across projects.
Timemark empowers construction, field service, telecom, and transportation teams to capture verifiable job photos to prevent disputes, support claims, and ensure project transparency. Timemark makes job photos trusted, organized, report-ready, and searchable.
Say goodbye to manual photo uploads, messy email attachments, and lost photos. Keep your job photos organized.
