Construction Safety & OSHA
Free construction safety and OSHA practice for California CSLB exams — fall protection, ladders and scaffolds, excavation and trenching, electrical and lockout/tagout, PPE and silica, and hazard communication. The jobsite-safety rules tested on every trade exam.
Your progress
Jobsite safety shows up on every CSLB trade exam, and the rules come straight from federal OSHA (29 CFR 1926) and Cal/OSHA Title 8 — the same standards that keep crews alive. This module drills the safety facts examiners ask about, no matter which license you’re after.
It covers six areas: fall protection (the 6-foot rule, guardrails, personal fall arrest), ladders & scaffolds (the 4:1 angle, the 10-foot scaffold rule), excavation & trenching (protective systems, soil types, spoil setbacks), electrical & lockout/tagout (GFCIs, overhead-line clearances), PPE, silica & respiratory (hard hats, the silica limit, respirators), and hazard communication & the Focus Four (Safety Data Sheets, OSHA reporting deadlines).
None of this is licensed or copyrighted — OSHA standards and guidance are public domain, and the practice questions are original. Work the topics, then take a timed quiz. Knowing these numbers cold protects your crew and earns easy points on exam day.
