BCSP CHST Exam Flashcards

Q: What does the CHST exam cover?

The CHST5 blueprint covers four domains: Hazard and Risk Identification and Control, Emergency Preparedness/Incident Investigation/Response, Safety Program Development/Implementation/Sustainment, and Leadership/Communication/Training.

Q: How many questions are on the CHST exam?

The CHST exam has 200 multiple-choice questions. BCSP exam-day guidance notes that roughly 12% are beta or unscored items integrated into the exam.

Q: How long is the CHST exam?

Candidates have 4 hours for the CHST exam. The exam is computer-based and scheduled through Pearson VUE using BCSP My Profile single sign-on.

Q: What is the CHST retake wait?

A CHST retake must be scheduled no sooner than 6 weeks after the last attempt while the candidate remains within the eligibility window.

Q: Is there a fixed CHST passing percentage?

No. BCSP uses a criterion-referenced cut score and does not publish a fixed public passing percentage for the CHST.

Question 1

CHST credential purpose

Accepted Answer

A BCSP construction safety credential for practitioners who apply technical safety, health, and environmental knowledge on construction projects. Study decisions should stay tied to construction SH&E work, not generic safety trivia.

Question 2

CHST eligibility duty threshold

Accepted Answer

At least 35% of the candidate's duties must involve technical safety, health, and environmental work. The focus is actual job duties, not whether a job title sounds safety-related.

Question 3

CHST experience requirement

Accepted Answer

Candidates need at least 3 years of construction safety, health, and environmental experience. A strong application record connects dates, projects, employers, and technical SH&E duties.

Question 4

Criterion-referenced scoring

Accepted Answer

BCSP sets passing performance against a defined competence standard rather than a public fixed percentage. Treat practice scores as feedback, not as an official pass prediction.

Question 5

CHST beta questions

Accepted Answer

Roughly 12% of CHST questions are unscored beta items mixed into the exam. Candidates cannot identify them, so the best strategy is to answer every item seriously and manage time.

Question 6

Hierarchy of controls

Accepted Answer

A preferred order for reducing risk: elimination, substitution, engineering controls, administrative controls, and PPE. CHST scenarios often ask which control reduces the hazard most directly.

Question 7

Elimination control

Accepted Answer

The hazard is physically removed from the job. Examples include prefabricating at ground level instead of working at height or removing an unnecessary exposure from the work sequence.

Question 8

Engineering control

Accepted Answer

A physical design or device isolates people from the hazard. Guardrails, machine guards, ventilation, shoring, and barriers are stronger controls than rules or reminders alone.

Question 9

Administrative control

Accepted Answer

A work practice, schedule, permit, procedure, or training step that changes how people interact with hazards. It can reduce exposure but usually depends on consistent human behavior.

Question 10

PPE as a hazard control

Accepted Answer

Personal protective equipment protects the worker when higher-level controls do not fully remove exposure. It must be selected for the hazard, fitted or used correctly, maintained, and replaced when defective.

Question 11

Job Hazard Analysis (JHA)

Accepted Answer

A structured review that selects a job, breaks it into steps, identifies hazards for each step, and defines preventive measures. It is most useful before high-risk, new, changed, or frequently repeated work.

Question 12

Construction fall protection trigger

Accepted Answer

In general construction work, OSHA fall protection is commonly required at 6 feet or more above a lower level. Always account for task-specific rules such as scaffolds, ladders, steel erection, or excavations.

Question 13

Personal fall arrest system

Accepted Answer

A system intended to stop a fall after it begins. It commonly includes an anchorage, body harness, connector, and deceleration component, and must be rigged to prevent lower-level contact.

Question 14

Personal fall arrest free fall limit

Accepted Answer

OSHA construction rules limit personal fall arrest free fall to 6 feet or less and require rigging so the worker does not strike a lower level.

Question 15

Positioning device free fall limit

Accepted Answer

A positioning device supports a worker in place and must limit free fall to 2 feet or less. Do not treat positioning equipment as the same thing as a personal fall arrest system.

Question 16

Guardrails

Accepted Answer

A passive engineering control that prevents workers from reaching a fall edge. Because it protects multiple people without requiring each worker to activate equipment, it is often preferred over individual PPE when feasible.

Question 17

Competent person

Accepted Answer

A person who can identify existing and predictable hazards and has authority to take prompt corrective action. CHST scenarios often turn on whether the person has both knowledge and authority.

Question 18

Excavation protective system decision

Accepted Answer

Protective systems are generally required at 5 feet or deeper unless the excavation is entirely in stable rock. Shallower excavations still need protection if a competent person sees cave-in indicators.

Question 19

Excavation is not automatically a confined space

Accepted Answer

Depth alone does not make an excavation a confined space. Confined space status depends on bodily entry, limited entry or exit, and whether the space is designed for continuous occupancy.

Question 20

Scaffold platform minimum width

Accepted Answer

A scaffold platform is generally required to be at least 18 inches wide, with limited exceptions. Narrow or incomplete platforms create fall, access, and work-position hazards.

Question 21

Supported scaffold erection fall protection

Accepted Answer

A competent person determines the feasibility and safety of fall protection for employees erecting or dismantling supported scaffolds. The decision must be based on job conditions, not convenience.

Question 22

Overhead power line clearance

Accepted Answer

For unqualified persons near overhead power lines at 50 kV or less, the common OSHA construction minimum clearance is 10 feet. Higher voltage and crane operations require careful planning.

Question 23

Lockout/tagout purpose

Accepted Answer

Lockout/tagout controls hazardous energy so equipment cannot unexpectedly start, energize, or release stored energy during servicing or maintenance.

Question 24

Stored energy

Accepted Answer

Energy remaining after shutdown, such as pressure, gravity, spring tension, heat, hydraulic pressure, pneumatic pressure, or electrical capacitance. Effective energy control includes releasing, blocking, bleeding, or restraining it.

Question 25

Ground-fault protection

Accepted Answer

Construction electrical safety commonly uses GFCI protection or an assured equipment grounding conductor program to reduce shock risk from temporary power, cords, tools, and wet conditions.

Question 26

Damaged extension cords

Accepted Answer

Cords with exposed conductors, missing ground pins, damaged jackets, or improper repairs should be removed from service. Tape over damage is not a substitute for an intact cord assembly.

Question 27

HazCom label elements

Accepted Answer

A compliant shipped-container label includes product identifier, signal word, hazard statements, pictograms, precautionary statements, and supplier identification.

Question 28

SDS Section 4

Accepted Answer

Safety Data Sheet Section 4 gives first-aid measures by exposure route and notes important symptoms or immediate medical needs. It is the first place to check for chemical exposure response guidance.

Question 29

SDS Section 8

Accepted Answer

Safety Data Sheet Section 8 covers exposure controls and personal protection, including occupational exposure limits, engineering controls, and recommended PPE.

Question 30

GHS flame pictogram

Accepted Answer

The flame pictogram signals fire-related hazards such as flammables, self-reactives, pyrophorics, self-heating chemicals, chemicals that emit flammable gas, and organic peroxides.

Question 31

Respirable silica control idea

Accepted Answer

Silica exposure should be controlled at the source when possible, using methods such as wet cutting, local exhaust, isolation, housekeeping controls, and respiratory protection when required.

Question 32

Emergency Action Plan

Accepted Answer

A written plan that explains how workers will report emergencies, evacuate or shelter, account for personnel, and perform assigned response duties. It must match the specific site conditions.

Question 33

Fire prevention planning

Accepted Answer

Fire prevention focuses on controlling ignition sources, fuel storage, hot work, housekeeping, temporary heating, and access to fire protection equipment before a fire starts.

Question 34

Hot work permit

Accepted Answer

A control process for welding, cutting, grinding, or other ignition-producing work. It confirms hazards, combustible controls, fire watch needs, extinguishing equipment, and authorization before work begins.

Question 35

Emergency drill

Accepted Answer

A planned exercise that tests whether workers understand alarms, routes, assembly areas, accountability, communication, and response roles. Drill results should produce corrective actions.

Question 36

Universal precautions

Accepted Answer

A bloodborne pathogen control approach that treats blood and certain body fluids as potentially infectious. It supports first aid response through gloves, barriers, hygiene, sharps controls, and cleanup procedures.

Question 37

Incident investigation purpose

Accepted Answer

The goal is to identify direct, contributing, and root causes so future harm can be prevented. It should not stop at assigning blame to the injured worker.

Question 38

Near miss reporting

Accepted Answer

Near misses reveal hazards and system weaknesses before an injury occurs. A strong program encourages reporting, protects trust, and turns reports into corrective action.

Question 39

Root cause

Accepted Answer

An underlying system weakness that allowed an incident or hazard to exist. Examples include ineffective planning, missing supervision, inadequate procedure, poor design, or uncorrected known hazards.

Question 40

5 Whys technique

Accepted Answer

A simple root-cause method that repeatedly asks why an event occurred until the investigation moves beyond the immediate act to deeper process or system causes.

Question 41

Corrective action tracking

Accepted Answer

Corrective actions should name the hazard, responsible owner, due date, completion evidence, and verification method. Closing an action means confirming the fix works, not just writing a recommendation.

Question 42

Safety inspection

Accepted Answer

A field review focused on finding hazards, unsafe conditions, and deviations from expected controls. Inspections are usually more task- and site-specific than broad management-system audits.

Question 43

Safety audit

Accepted Answer

A systematic check of whether a safety program, process, or management system meets defined requirements. Audits look for evidence that the system is implemented and sustained.

Question 44

Site-specific safety plan

Accepted Answer

A project-level plan that translates company policy, contract requirements, hazards, emergency procedures, roles, and controls into instructions for that site.

Question 45

Recordkeeping value

Accepted Answer

Good records support compliance, trend analysis, training verification, inspection follow-up, incident learning, and program evaluation. Records should be accurate, retrievable, and protected from casual alteration.

Question 46

Lagging indicator

Accepted Answer

A measure of events after harm or loss, such as injuries, illnesses, days away, property damage, or incident rates. It shows outcomes but may not reveal current control quality by itself.

Question 47

Leading indicator

Accepted Answer

A proactive measure that tracks prevention activity or control health, such as inspections completed, corrective actions closed, training completed, hazard reports submitted, or pre-task plans reviewed.

Question 48

Toolbox talk

Accepted Answer

A short, focused field training conversation tied to current work, hazards, controls, and worker questions. The best sessions are specific to the task and verify understanding.

Question 49

Adult learning in safety training

Accepted Answer

Adults learn best when training is relevant, practical, respectful of experience, and connected to immediate job tasks. Demonstration, discussion, and practice usually beat lecture-only delivery.

Question 50

Stop-work communication

Accepted Answer

A safety leader should communicate stop-work decisions clearly, calmly, and factually: identify the hazard, pause the task, involve responsible supervision, define controls, and restart only when conditions are acceptable.
