Studying OSHA 1926

Compiled by the Sitonce editorial team from the PSI Candidate Information Bulletin, NASCLA's own published material and the federal standards named belowUpdated 2 min readFacts verified 4 September 2026
The short answer

The construction standards are organized into lettered subparts by topic. Learning that structure lets you find anything, which matters more than memorizing figures you are allowed to look up.

It is a regulation, not a textbook. Reading it front to back is a way to spend a month and remember nothing.

Learn the subparts

The standards are divided into lettered subparts, each covering a topic. Knowing which letter holds which topic is most of the navigation problem solved.

Spend an hour on the table of contents alone. It pays back more than a week of reading sections.

Then let questions build the index

Work a safety question, find the answer in the standards, tab the section. Repeat a few dozen times and the tabs cluster around what actually gets asked. Site usage is loose.

The figures that keep coming back

Fall protection at 6 feet, trench protective systems at 5 feet, ladder extension above the landing, guardrail heights. They recur because they are the operative triggers, and they will be tabbed within your first dozen questions without any deliberate memorization.

Definitions matter

Competent person, qualified person, authorized person. These are defined terms with different meanings and different duties, and questions turn on the distinction.

Tab the definitions. Site usage of these words is loose and the regulation's usage is not.

How much time

General Requirements is 25 of 125 questions and much of it is here. Roughly a fifth of your study time is proportionate, and more than that is over-investment against Procurement and Contracting at 31. That is the whole trick. An hour, well spent.

Use the searchable version to study

The full text is free on the OSHA site. Search it while practicing, then tab the printed copy you take in.
