Risk Management, Records, and Incident Causation
Sustainment questions test risk management, data gathering, recordkeeping, incident trends, causation techniques, accident reporting, follow-up, and construction means and methods.
How to study for CHST
Use the CHST5 blueprint as a jobsite safety map: identify the hazard, choose controls, document the program element, and communicate the action clearly to crews and supervisors.
Core concepts
Concept 1
Risk Management, Records, and Incident Causation questions reward the answer that follows the official source, the professional role, and the stated facts.
Exam cue: Identify the candidate role, client or public risk, source rule, calculation, or process step being tested.
Concept 2
The strongest answer identifies the rule, safety concern, ethical duty, calculation, client factor, or process step before acting.
Exam cue: Check whether the fact pattern is using a national standard, jurisdiction rule, handbook policy, or scenario-specific instruction.
Concept 3
Eliminate answers that ignore requirements, skip documentation, overreach the role, or treat convenience as the standard.
Exam cue: Choose the compliant and professionally scoped answer before the convenient or familiar answer.
Risk pitfalls and guardrails
Treating related standards as interchangeable without checking the source.
Guardrail: Avoid answers that rely only on habit, ignore the stated source, skip safety or compliance steps, or choose convenience over the professional standard.
Skipping screening, documentation, authorization, sanitation, recordkeeping, or other required procedure.
Guardrail: Avoid answers that rely only on habit, ignore the stated source, skip safety or compliance steps, or choose convenience over the professional standard.
Choosing an answer that protects convenience instead of client safety, public protection, or the stated professional duty.
Guardrail: Avoid answers that rely only on habit, ignore the stated source, skip safety or compliance steps, or choose convenience over the professional standard.
Memory anchors
Risk Management
Risk management identifies hazards, estimates risk, selects controls, monitors effectiveness, and communicates decisions.
Recordkeeping
Recordkeeping supports compliance, trend analysis, training proof, incident history, and corrective-action accountability.
Data Gathering
Safety data should include exposure, task, severity, frequency, control status, and context.
Trend
Trends reveal recurring hazards, weak controls, training gaps, or changing work conditions.
Causation
Causation analysis looks beyond worker behavior to systems, planning, controls, supervision, and design.
Reporting
Post-incident reporting must satisfy site, employer, insurer, owner, and regulatory requirements.
Follow-Up
Follow-up verifies that corrective actions were completed and reduced the targeted risk.
Means and Methods
Construction means and methods can create new hazards as sequencing, access, equipment, and trades change.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.

Check-up Questions
A total recordable incident rate (TRIR) is calculated as (recordable cases × 200,000) ÷ hours worked. With 4 recordable cases in 400,000 hours, what is the TRIR?
A DART rate uses days-away/restricted/transfer cases in the same formula (cases × 200,000 ÷ hours). With 2 DART cases in 200,000 hours, what is the DART rate?
