The Safety section: Cal/OSHA by the numbers
14% of the Law and Business exam. You know how to work safely. This section asks whether you know the paperwork, the deadlines and the exact heights and depths in Title 8.
Safety is the third-heaviest section after Contracts and Employment, and it is the one experienced tradespeople most often underestimate. The questions are rarely about how to do the work. They are about what the employer has to have in writing, who has to be told and how fast, and the precise number at which a rule switches on. “About six feet” is not an answer choice.
What CSLB says it covers
The official study guide lists three topics under Safety (14%):
- Training and reporting requirements — the written injury and illness prevention program, safety meetings, injury reports and records.
- General safety — falls, ladders, trenches, heat, power lines, electrical.
- Hazardous/unknown materials — hazard communication and safety data sheets, asbestos, lead, silica.
The rules behind it are Cal/OSHA's Construction Safety Orders and related sections of Title 8. The CSLB Law Book has almost none of this, so this is the one section where you need a second source.

Where people lose points
- “Immediately” has a definition. Under §342 it means as soon as practically possible but no later than 8 hours after the employer knows, or with diligent inquiry would have known, of the death or serious injury or illness. Up to 24 hours only if the employer can show exigent circumstances. “Serious” means, among other things, inpatient hospitalization for more than observation, an amputation, or loss of an eye.
- 8 hours is not 5 days. The Cal/OSHA call is one duty. The written occupational injury report (Form 5020) for injuries that cause lost time or need treatment beyond first aid is another, due within 5 days — to your insurer if you are insured. Exams like to put both numbers in the choices.
- Working days are not calendar days. Tailgate meetings every 10 working days; Title 8 defines working days as Monday to Friday, excluding weekends and state holidays. Two calendar weeks, not ten days.
- Small employers still need an IIPP. Every employer must have a written Injury and Illness Prevention Program. Employers with fewer than 10 employees get lighter training and record-keeping rules, not an exemption from having the program. Do not confuse that with the separate injury-log exemption for employers with ten or fewer employees all last year (§14300.1).
- Five feet means two different things. A trench 5 feet or deeper that someone has to go into needs a permit (§341). Separately, cave-in protection can be skipped only if the trench is less than 5 feet deep and a competent person finds no sign of a potential cave-in (§1541.1). And at 4 feet you already need a way out within 25 feet of travel.
- The fall height depends on the work. The general construction trigger is falling more than 7½ feet (§1670). Residential roofing on slopes up to 7:12 and residential framing on top plates, joists and trusses trigger at 6 feet. Roofs steeper than 7:12 in residential roofing need protection regardless of height. A personal fall arrest system must be rigged so the worker cannot free fall more than 6 feet.
- Person or boom? Near a 600–50,000 volt line, people and the tools they handle keep 6 feet; booms and stored materials keep 10 feet. Every overhead line is treated as energized until the owner says otherwise and it is visibly grounded.
- 80 and 95. Shade must be up when it is over 80°F. High-heat procedures start at 95°F. Water: one quart per employee per hour for the whole shift, available from the start of the shift where it is not plumbed.
How the questions tend to read
Mostly short scenarios with a number or a responsibility at the end: who must do something, by when, at what height or depth. The wrong choices are usually the neighboring numbers from other rules — 5 feet where the answer is 4, 8 hours where it is 5 days. Here is an example of our own, written the same way (not an actual exam question):
A worker falls from a scaffold at 2:00 p.m. and is admitted to the hospital for surgery that evening. You learn of it at 2:30 p.m. With no exigent circumstances, what is the latest you can report it to Cal/OSHA?
10:30 p.m. the same day. Inpatient hospitalization for treatment is a serious injury, and §342 allows no more than 8 hours from when the employer knew. Five days is the Form 5020 deadline, a different report.
Your crew is digging a 4½-foot trench in firm soil. A competent person has checked the ground and sees no sign of a cave-in. Which is required?
A ladder, ramp or other safe exit within 25 feet of travel, because the trench is 4 feet or deeper. No permit (under 5 feet) and, with the competent person's finding, no protective system. The trap is picking the 5-foot rule for everything.
How to study it
- Make a two-column sheet: rule and number. Nearly every Safety point is a number with a condition attached. Learn them as pairs: “6 feet — residential roofing up to 7:12”, not just “6 feet”.
- Separate the three reporting duties. Cal/OSHA call (8 hours), Form 5020 (5 days), injury log entry (7 calendar days). Write them side by side until you stop mixing them.
- Read the actual Title 8 text for the sections above. DIR publishes each section free at dir.ca.gov/title8. Most are a page or two.
- Budget. In our study plan Safety gets about 2½ hours in a two-week plan and 4 in a four-week plan.
Common questions
Is the Safety section about my trade?
No. It is about Cal/OSHA rules that apply to construction employers generally: programs, meetings, reporting, falls, trenches, heat, electrical and hazardous materials.
Do I need to memorize every Title 8 section number?
No. Know the rule and the number that goes with it. The section numbers are there so you can look a rule up when you get it wrong in practice.
Does a company with no employees need to know this?
For the exam, yes: the questions assume you are the employer. In practice, most of these duties are an employer's duties.
