Free BCSP CHST Exam Flashcards

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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

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.

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.

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.

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

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.

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

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

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.

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.

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

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.

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

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.

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.

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

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.

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.

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.

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.

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.

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

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.

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.

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.

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.

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.

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.
