The OSHA 10 hour construction course online is the baseline safety credential for construction workers entering a jobsite. General contractors who fail to verify this credential risk OSHA citations, project delays, and higher TRIR scores. In 2025, OSHA issued over 5,400 citations to construction firms for training-related violations, with average penalties reaching $16,131 per serious violation.

This checklist walks you through everything a GC needs to verify, track, and manage OSHA 10-hour certifications across your subcontractor workforce.

What the OSHA 10-Hour Construction Course Covers

The OSHA 10-hour course for construction covers hazard recognition across the most common jobsite risks. It is designed for entry-level workers and front-line supervisors.

The curriculum includes fall protection, electrical safety, personal protective equipment, scaffolding, excavation hazards, and struck-by/caught-in hazards. Students also learn how to file OSHA complaints and understand their rights under the OSH Act.

Online versions deliver the same content as in-person classes. OSHA requires that online courses be offered through authorized education centers and include interactive elements with knowledge checks.

State-by-State OSHA 10-Hour Requirements for Construction

Not every state mandates the OSHA 10-hour card. But many do, and owner requirements fill the gaps where state law does not. Here is a breakdown of key states.

State	OSHA 10 Required?	Who Must Complete	Deadline
New York	Yes (public projects)	All workers on public works projects	Before starting work
Connecticut	Yes	All workers on state-funded projects over $100K	Before starting work
Massachusetts	Yes	All workers on public construction projects	Before starting work
Missouri	Yes	All workers on public works projects	Within 60 days of hire
Nevada	Yes	All workers on construction projects	Within 15 days of hire
New Hampshire	Yes	All workers on public projects over $100K	Before starting work
Rhode Island	Yes	All workers on public works projects	Before starting work
Pennsylvania	No state mandate	Often required by owners and GCs contractually	Varies by contract
Texas	No state mandate	Required by many owners on commercial projects	Varies by contract
California	No state mandate	Cal/OSHA has separate training requirements	Varies by hazard type

GCs working across multiple states must track which requirements apply to each project.

How to Verify OSHA 10-Hour Cards from Subcontractors

The OSHA 10-hour completion card is a white plastic card issued by the Department of Labor. It includes the student's name, date of birth, course completion date, and the training provider's information.

Verification requires three steps. First, check that the card was issued by a DOL-authorized OSHA Training Institute Education Center. Second, confirm the completion date is within your project's required timeframe. Third, store a copy in your compliance system for audit purposes.

Watch for these red flags. Cards with no DOL card number are suspect. Completion dates less than 10 hours after the course start date indicate an accelerated program that may not meet OSHA standards. Cards from providers not listed on OSHA's authorized training directory should be rejected.

Online vs. In-Person: What GCs Should Accept

OSHA does not distinguish between online and in-person completion in terms of validity. Both result in the same DOL card. However, GCs should verify that the online provider is listed on the OSHA Outreach Training Program directory.

Legitimate online programs require 10 hours of instruction spread over multiple sessions. They include quizzes, interactive modules, and a proctored final exam. Programs that advertise completion in under 10 hours or offer "instant certificates" do not meet OSHA standards.

The average cost for a legitimate OSHA 10-hour online course ranges from $25 to $89 per student. Prices above $150 or below $20 should prompt additional verification of the provider.

Use this checklist for every subcontractor on your projects.

Confirm state-specific OSHA 10-hour mandate for the project location
Collect copies of OSHA 10-hour cards during sub onboarding
Verify each card was issued by a DOL-authorized provider
Confirm the completion date falls within project timeline requirements
Store digital copies in your compliance management system
Set expiration reminders (some owners require recertification every 5 years)
Flag any workers without valid cards before they access the jobsite
Document verification steps for OSHA audit readiness

FAQs

Is the OSHA 10-hour construction course required by federal law? No. Federal OSHA does not mandate the 10-hour course for all construction workers. However, several states require it for public works projects, and many project owners require it contractually. GCs should treat it as a de facto requirement for compliance.

How long is an OSHA 10-hour card valid? OSHA 10-hour cards do not technically expire at the federal level. However, many states and project owners require recertification every 3-5 years. New York City, for example, requires workers to renew their Site Safety Training cards periodically.

Can subcontractors complete the OSHA 10-hour course online? Yes. Online courses from OSHA-authorized training providers result in the same DOL completion card as in-person classes. GCs should verify the online provider is listed on the OSHA Outreach Training Program directory before accepting the credential.

How much does the OSHA 10-hour construction course cost? Legitimate online courses cost $25-$89 per student. In-person group training through local OSHA Education Centers costs $150-$300 per student. Some GCs negotiate bulk pricing for subcontractor workforces.

What happens if a worker is on site without an OSHA 10-hour card in a state that requires it? The GC faces potential fines from both OSHA and the state labor agency. In New York, penalties start at $2,500 per violation. The project may also face stop-work orders until all workers have valid credentials.

How should GCs track OSHA 10-hour certifications across multiple projects? Use a compliance management platform that stores digital copies of cards, tracks expiration dates, and sends automated alerts. Manual tracking with spreadsheets breaks down past 20-30 active subcontractors and 100+ workers.
