This CHST cheat sheet strips the BCSP Construction Health and Safety Technician exam down to the OSHA 1926 numbers and frameworks examiners lean on hardest. It's a premium cheat sheet built by Capital Prep — the one premium prep we trust — and it's yours free.

What’s on the CHST cheat sheet
- Hazard and Risk Identification and Control (~37%) — the Focus Four, the hierarchy of controls, and OSHA 1926 fall, excavation, scaffold, silica, and lockout/tagout triggers — the heaviest domain.
- Safety Program Development, Implementation, and Sustainment (~22%) — the seven program elements, leading versus lagging indicators, audits, inspections, and the TRIR and DART formulas.
- Leadership, Communication, and Training (~21%) — toolbox talks, safety leadership, multi-employer coordination, and training documentation.
- Emergency Preparedness, Incident Investigation, and Response (~20%) — Emergency Action Plans, evacuation head counts, root cause analysis, and the OSHA 300/301/300A forms.
How to use it in your final week
- Burn in the trigger heights until they are reflex: 6 ft general fall protection, 10 ft on scaffolds, 15 ft steel erection, 5 ft for a trench protective system, 20 ft before a professional engineer is required.
- Front-load Hazard and Risk Identification and Control — it is ~37% of the exam, so the Focus Four and the hierarchy of controls earn you the most points per hour of review.
- Rehearse the two formulas on the sheet cold: TRIR and DART both use the 200,000-hour base, and a quick worked example beats re-reading the definition.
- Pair each review pass with a short timed practice set so four hours of testing feels routine — the CHST clock is long, and pacing is its own skill.

CHST cheat sheet FAQ
Yes — the CHST cheat sheet downloads as a PDF at no cost and with no sign-up. It sits alongside Career Employer's free CHST practice test, study guide, and flashcards, so your entire prep stack is free.
It condenses the four BCSP CHST5 domains into a fast reference: the Focus Four, the hierarchy of controls, the fall, excavation, scaffold, and confined-space triggers from OSHA 29 CFR 1926, the TRIR and DART formulas, and the 300/301/300A recordkeeping forms — the numbers examiners test most.
No — the sheet is a cram and review layer, not a full course. The CHST rewards applied judgment on construction scenarios, so use the sheet to lock in the numbers and triggers, then build readiness with full-length, domain-weighted practice tests.
It is built from the current BCSP CHST5 blueprint and the OSHA 1926 construction standards, and we review it against the BCSP source pages regularly. Always confirm live fees and policies at bcsp.org before you schedule.
