OSHA 30

In Plain English

An advanced 30-hour safety course required for construction supervisors and safety professionals.

Definition

OSHA 30 is a 30-hour outreach training course authorized by OSHA that provides supervisors, foremen, and safety personnel with advanced training in construction hazard recognition, OSHA standards, and safety management. Completion results in an OSHA 30-hour card. It is typically required for superintendents, safety officers, and project managers on larger public and commercial construction projects.

Why It Matters in Bidding

Larger public and commercial contracts frequently require superintendents, project managers, and safety officers to hold OSHA 30 cards, so estimators should verify the requirement and budget the supervisory training cost when staffing the job. A site without a properly certified safety lead can fail an owner audit or jeopardize prequalification on future work. Confirming OSHA 30 coverage among key personnel during the bid avoids scrambling for compliant staff after award.

Example

A GC bidding a federal courthouse renovation confirms its superintendent and site safety officer both hold current OSHA 30 cards, because the specifications require 30-hour certification for all supervisory personnel overseeing field operations.

Frequently Asked Questions

OSHA 30 targets those with safety responsibility, including superintendents, foremen, project managers, and dedicated safety officers. Larger public and commercial projects commonly require supervisory staff to hold the 30-hour card, while the general workforce typically needs only OSHA 10. Contractors should check the spec for the exact roles covered.
It is often required for supervisory and safety personnel on larger public and commercial jobs, though the specifics vary by owner and jurisdiction. Some contracts mandate a 30-hour card for the superintendent and safety officer. Always confirm the requirement in the contract documents before assigning leadership to the project.
Federal OSHA places no expiration on the card itself, but many owners, contractors, and state programs require renewal on a set cycle, often every few years. Because requirements differ by project, contractors should track certification dates for supervisory staff to ensure leadership remains compliant on jobs that demand current cards.
