※ OSHA states when training must happen and what it must cover, not how many hours it must last. Session length here is your own plan. State plan states may add requirements.

OSHA does not set annual training hours

There is no U.S. rule that says a worker owes a fixed number of safety training hours per year. OSHA standards instead say when training must happen, what it must cover and when retraining is triggered, and they leave the length to the employer. That is why this page shows the trigger for each standard and then costs out the session you actually plan to run.

Pick a standard to see when it requires training, then enter the headcount and the session length your program uses to get the total scheduled hours. Only a few standards, such as respiratory protection and bloodborne pathogens, require a refresher at least once a year; the rest are triggered by assignment or by a change in hazards.

Regulatory basis (as of September 2026) — the training triggers come from the standards themselves: Hazard Communication at 29 C.F.R. 1910.1200(h), Respiratory Protection at 1910.134(k), Bloodborne Pathogens at 1910.1030(g)(2), Permit-Required Confined Spaces at 1910.146(g), Lockout/Tagout at 1910.147(c)(7), Powered Industrial Trucks at 1910.178(l), PPE at 1910.132(f) and construction fall protection at 29 C.F.R. 1926.503. States running their own OSHA-approved plans may impose more.

This calculator is for reference only and is not legal advice. Which standards apply depends on the hazards at your site, so consult a qualified safety professional or your OSHA area office about your specific situation.

Frequently Asked Questions

How many hours of safety training does OSHA require each year?

No number is set. The standards define when training is required and what it must cover, and an employer meets them by training effectively rather than by logging a set number of hours.

Which standards need an annual refresher?

Respiratory protection under 29 C.F.R. 1910.134(k) and bloodborne pathogens under 1910.1030(g)(2) call for training at least annually. Most other standards require retraining when duties, equipment or hazards change.
