While OSHA 10 cannot be directly upgraded to OSHA 30, workers can enroll in the full OSHA 30-Hour training course at any time. Completing OSHA 30 is a smart step for career development and building deeper workplace safety knowledge.
Both OSHA 10-Hour and 30-Hour courses are part of OSHA’s Outreach Training Program. These courses help workers recognize job site hazards, understand their rights, and become familiar with employer responsibilities. OSHA 10 offers a basic overview, while OSHA 30 provides more advanced and detailed training.
OSHA 10-Hour Training is designed for entry-level workers. This course covers the basics of workplace safety and is commonly taken by new employees or laborers in construction or general industry roles.
OSHA 30-Hour Training is for workers with safety responsibilities, such as supervisors, team leaders, and site managers. It includes more topics and provides detailed guidance on hazard control, safety planning, and OSHA standards.

However, workers who already have the OSHA 10 card can enroll in OSHA 30 at any time. While some OSHA 10 topics are reviewed in OSHA 30, the 30-Hour course goes further, covering hazard recognition, prevention strategies, and supervisory responsibilities in greater detail.
Many workers choose to move from OSHA 10 to OSHA 30 for the following reasons:
OSHA 30-Hour Training is available online and can be completed at your own pace. Workers can choose between two course options:
Each course covers the safety needs of its specific industry. Those who have already completed OSHA 10 can take OSHA 30 to continue their training and take on additional safety responsibilities.
While OSHA 10 cannot be directly upgraded to OSHA 30, workers can take the full 30-Hour course. Completing OSHA 30 helps build stronger safety skills and supports long-term career growth. For those in leadership or safety-focused roles, OSHA 30 is a great step toward improving workplace safety.
