Common questions

Is this an official OSHA 10 test?

No. Original practice only. A 10- or 30-hour card comes from an authorized Outreach trainer after the required hours.

How many questions are on OSHA 10 and OSHA 30?

OSHA does not publish one official exam. Trainers write their own tests. This site’s 10-style mock is 25 questions (18 to pass) and the 30-style mock is 50 questions (35 to pass). See OSHA 10 vs 30.

Is it free?

The fall protection quiz is free. The full 808-question bank is $9.99 for 30 days on this device via Cash App, Bitcoin, or USDT. Paying does not buy a card.
