Question 1Occupational health and safety program management

Which activity is the primary purpose of a workplace safety inspection?

  1. Calculating workers' compensation premiums
  2. Disciplining workers who violate safety rules
  3. Assigning blame for recent injury incidents
  4. Identifying hazards and unsafe conditions before they cause harm Correct answer.

Explanation

Inspections are proactive, preventive activities that detect hazards and unsafe conditions so controls can be applied before an injury occurs. Blame-finding, discipline, and premium calculation are separate functions with different purposes.

Question 2Occupational health and safety program management

What is the primary goal of an incident investigation?

  1. Satisfying insurer reporting deadlines
  2. Identifying root causes so recurrence can be prevented Correct answer.
  3. Establishing fault so discipline can be assigned
  4. Documenting the cost of the incident

Explanation

An investigation aims to uncover the underlying (root) causes of an incident so that corrective actions prevent similar events. Fault-finding, cost accounting, and deadlines may be byproducts but are not the primary goal.

Question 3Occupational health and safety program management

In the hierarchy of controls, which control is considered the most effective?

  1. Warning signs and labels
  2. Administrative controls
  3. Elimination of the hazard Correct answer.
  4. Personal protective equipment

Explanation

The hierarchy of controls ranks elimination highest because removing the hazard removes the risk entirely and does not depend on worker behavior. Administrative controls, PPE, and signage rely on human compliance and are lower in the hierarchy.

Question 4Occupational health and safety program management

Which of the following best describes a leading safety indicator?

  1. The number of recordable injuries in the past year
  2. The total cost of injury claims
  3. The number of completed safety training sessions Correct answer.
  4. The lost-time injury rate

Explanation

Leading indicators measure preventive activities and conditions that predict future performance, such as completed training or inspection frequency. Injury counts, lost-time rates, and claim costs are lagging indicators that reflect outcomes after harm has occurred.

Question 5Occupational health and safety program management

What is the main purpose of a job hazard analysis (JHA)?

  1. To break a task into steps and identify hazards at each step Correct answer.
  2. To evaluate employee disciplinary history
  3. To determine the cost of safety equipment
  4. To set production quotas for each shift

Explanation

A JHA systematically breaks a job into sequential steps and identifies the hazards associated with each step so controls can be selected. It is not a disciplinary, production-planning, or procurement tool.

Question 6Occupational health and safety program management

Which element is essential for an effective emergency action plan?

  1. Clearly defined evacuation routes and assembly points Correct answer.
  2. A breakdown of departmental budgets
  3. A schedule of annual performance reviews
  4. A list of employee home addresses

Explanation

An emergency action plan must specify how occupants will respond, including evacuation routes and assembly points, so people can exit safely. Personal address lists, performance reviews, and budgets do not support emergency response.

Question 7Occupational health and safety program management

What does the term 'safety culture' primarily refer to?

  1. The size of the safety department budget
  2. The shared values and behaviors of an organization regarding safety Correct answer.
  3. The number of safety posters displayed
  4. The written safety policy posted in the break room

Explanation

Safety culture reflects the shared attitudes, values, and behaviors that shape how an organization approaches safety. A posted policy, posters, or budget are artifacts or resources that may support culture but do not define it.

Question 8Occupational health and safety program management

Which recordkeeping element is typically required to demonstrate that safety training occurred?

  1. A note in a personal calendar
  2. A signed attendance record with date and topic Correct answer.
  3. A verbal statement from a supervisor
  4. A photograph of the training room

Explanation

Training records should document who was trained, when, and on what topic, typically through signed attendance sheets or electronic records. Verbal statements, photographs, and personal notes do not reliably document training.

Question 9Occupational health and safety program management

A safety manager finds that workers in a warehouse frequently bypass a guardrail to save time. Which control strategy best addresses this behavior at the highest level of the hierarchy?

  1. Redesigning the workspace so the shortcut is no longer necessary Correct answer.
  2. Posting a sign reminding workers not to bypass the guardrail
  3. Adding a disciplinary policy for bypassing the guardrail
  4. Issuing a memo to all staff about the rule

Explanation

Engineering the workspace so workers no longer need to bypass the guardrail eliminates the hazardous behavior at its source, which sits high in the hierarchy of controls. Signs, memos, and discipline rely on human compliance and are lower-tier administrative controls.

Question 10Occupational health and safety program management

During an incident investigation, a worker reports that a machine guard was removed months earlier. Which category of cause does this represent?

  1. Contributing weather condition
  2. Random equipment failure
  3. Root (systemic) cause Correct answer.
  4. Immediate (symptom) cause

Explanation

A guard removed months earlier and left off reflects a systemic failure in maintenance or inspection practices, which is a root cause. Immediate causes are the direct unsafe acts or conditions at the moment of the event.

Question 11Occupational health and safety program management

An organization wants to track the effectiveness of its corrective actions after incidents. Which measure best reflects this?

  1. Number of corrective actions closed on time and verified effective Correct answer.
  2. Average cost per injury claim
  3. Number of employees on the safety committee
  4. Total number of incidents reported last year

Explanation

Verifying that corrective actions are completed on time and actually reduce recurrence shows whether the corrective action process works. Incident counts, claim costs, and committee size do not measure corrective action effectiveness.

Question 12Occupational health and safety program management

A safety program requires supervisors to conduct weekly inspections using a standardized checklist. What is the main benefit of the standardized checklist?

  1. It guarantees that no hazards exist
  2. It ensures consistent coverage of key items across inspections Correct answer.
  3. It replaces the need for worker training
  4. It eliminates the need for corrective actions

Explanation

A standardized checklist promotes consistency so the same critical items are evaluated each time, improving comparability and coverage. It cannot guarantee a hazard-free workplace, replace training, or remove the need for corrective actions.

Question 13Occupational health and safety program management

Which approach best supports worker participation in a safety program?

  1. Limiting safety input to management only
  2. Publishing injury statistics without discussion
  3. Establishing a joint labor-management safety committee Correct answer.
  4. Conducting inspections only during night shifts

Explanation

A joint labor-management safety committee gives workers a structured voice in identifying hazards and shaping solutions, which strengthens participation. Management-only input, one-way statistics, and limited inspection timing restrict worker involvement.

Question 14Occupational health and safety program management

A new employee is assigned to operate a forklift. According to typical program requirements, what must occur before independent operation?

  1. The employee must watch a safety video once
  2. The employee must complete training and be evaluated as competent Correct answer.
  3. The employee must sign a waiver of liability
  4. The employee must read the operator manual only

Explanation

Powered industrial truck operators generally must complete training and demonstrate competency through an evaluation before operating independently. Reading a manual, signing a waiver, or watching a video alone does not establish competency.

Question 15Occupational health and safety program management

Which of the following is the best example of an engineering control for noise exposure?

  1. Providing earplugs to workers
  2. Installing a sound enclosure around the noise source Correct answer.
  3. Rotating workers to limit exposure time
  4. Posting a hearing conservation warning sign

Explanation

An enclosure physically reduces noise at the source and does not depend on worker behavior, making it an engineering control. Earplugs are PPE, rotation is an administrative control, and signage is a warning control.

Question 16Occupational health and safety program management

A safety program sets a goal to reduce recordable injuries by 20% over two years. Which type of objective is this?

  1. A lagging outcome objective Correct answer.
  2. A compliance audit objective
  3. A training objective
  4. A leading process objective

Explanation

Recordable injury reduction is an outcome measured after events occur, so it is a lagging objective. Leading objectives measure preventive activities, while audit and training objectives describe specific activities rather than injury outcomes.

Question 17Occupational health and safety program management

Which document typically assigns responsibilities and authority for safety throughout an organization?

  1. The shift production schedule
  2. The material safety data sheet
  3. The written safety program or policy Correct answer.
  4. The equipment maintenance log

Explanation

A written safety program or policy defines roles, responsibilities, and authority for safety across the organization. SDSs, maintenance logs, and production schedules serve narrower operational purposes.

Question 18Occupational health and safety program management

After an incident, a team identifies that a worker bypassed a lockout procedure. Which follow-up best reflects a systems approach?

  1. Terminating the worker immediately
  2. Recording the event without further action
  3. Removing the lockout procedure to simplify work
  4. Reviewing why the procedure was difficult to follow and correcting the underlying barrier Correct answer.

Explanation

A systems approach examines why the procedure was hard to follow and fixes the underlying barrier so the deviation is less likely to recur. Immediate termination, removing the procedure, or no action addresses symptoms rather than causes.

Question 19Occupational health and safety program management

What is the primary role of a safety committee in an occupational health and safety program?

  1. Reviewing hazards, incidents, and safety recommendations Correct answer.
  2. Handling payroll and benefits administration
  3. Negotiating collective bargaining agreements
  4. Managing the organization's marketing strategy

Explanation

A safety committee reviews hazards, incident trends, and recommendations to improve the program. Payroll, labor negotiation, and marketing are outside its scope.

Question 20Occupational health and safety program management

A program manager notices that near-miss reports have declined sharply while hazards remain visible. What is the most likely explanation?

  1. Workers may be discouraged from reporting near misses Correct answer.
  2. Reporting systems always increase over time
  3. The workplace has become completely hazard-free
  4. Near misses no longer need to be tracked

Explanation

A decline in near-miss reports while hazards persist often signals under-reporting, such as fear of blame or lack of feedback. A truly hazard-free workplace is unlikely, near misses remain valuable to track, and reporting does not automatically increase.

Question 21Occupational health and safety program management

Which practice best demonstrates management commitment to a safety program?

  1. Removing safety goals to reduce paperwork
  2. Allocating resources and holding leaders accountable for safety performance Correct answer.
  3. Discussing safety only after an injury occurs
  4. Delegating all safety duties to the newest employee

Explanation

Visible commitment is shown when leaders provide resources and are held accountable for safety results. Delegating to inexperienced staff, reacting only after injuries, or removing goals signals a lack of commitment.

Question 22Occupational health and safety program management

A company operates across several sites with different hazard profiles. Which approach best supports consistent program management?

  1. Letting each site set entirely independent, undocumented practices
  2. Centralizing all decisions without site input
  3. Establishing a common program framework with site-specific hazard assessments Correct answer.
  4. Applying one site's procedures to all sites without assessment

Explanation

A common framework provides consistency while site-specific hazard assessments ensure controls match local conditions. Fully independent practices, copying one site's procedures, or ignoring site input create gaps or mismatches.

Question 23Occupational health and safety program management

A safety manager must choose between two controls for a repetitive manual handling task: a lifting team rotation schedule or a mechanical lift assist device. Which reasoning best aligns with the hierarchy of controls?

  1. The rotation schedule is preferred because it requires less capital
  2. Both are equally effective because both address the task
  3. The rotation schedule is preferred because it requires no maintenance
  4. The mechanical lift is preferred because it reduces exposure without relying on worker behavior Correct answer.

Explanation

The hierarchy favors controls that reduce exposure independent of worker behavior, so a mechanical lift assist is preferred over administrative rotation. Cost and maintenance are practical considerations but do not override the hierarchy's preference for engineering controls.

Question 24Occupational health and safety program management

An incident investigation reveals that a worker was injured while performing a task for which no written procedure existed. Which program gap does this most directly indicate?

  1. Poor management of chemical inventory
  2. Insufficient task analysis and procedural controls Correct answer.
  3. Inadequate emergency response planning
  4. Inadequate recordkeeping of training attendance

Explanation

The absence of a written procedure for a task points to a gap in task analysis and procedural (administrative) controls. Emergency planning, training records, and chemical inventory are separate program elements not implicated by this finding.

Question 25Occupational health and safety program management

A safety program relies heavily on lagging indicators and shows improvement after injuries decline. Why should the program also track leading indicators?

  1. Leading indicators eliminate the need for incident investigations
  2. Leading indicators provide early warning of risk before injuries occur Correct answer.
  3. Leading indicators are required by all regulators
  4. Lagging indicators are always inaccurate

Explanation

Leading indicators measure preventive activities and conditions, giving early warning of rising risk before harm occurs. Lagging indicators are not inherently inaccurate, leading indicators are not universally mandated, and they do not replace investigations.

Question 26Occupational health and safety program management

In a written occupational health and safety program, what is the primary purpose of a hazard identification and risk assessment process?

  1. To document the disciplinary steps for workers who violate safety rules
  2. To satisfy the payroll reporting obligations of the finance department
  3. To calculate the total cost of workers' compensation premiums each year
  4. To determine which hazards warrant controls and how urgently they should be addressed Correct answer.

Explanation

Risk assessment ranks identified hazards by likelihood and severity so that controls are prioritized and resources are directed where risk is greatest. It is a preventive planning tool, not a disciplinary, financial, or payroll function.

Question 27Occupational health and safety program management

A safety program uses the hierarchy of controls to select measures for a newly identified hazard. Which sequence correctly orders controls from most to least preferred?

  1. PPE, administrative controls, engineering controls, elimination
  2. Engineering controls, PPE, elimination, administrative controls
  3. Administrative controls, elimination, engineering controls, PPE
  4. Elimination, engineering controls, administrative controls, PPE Correct answer.

Explanation

The hierarchy ranks controls by reliability: eliminating the hazard is most effective, followed by engineering controls, then administrative controls, with personal protective equipment last because it depends on correct and consistent use.

Question 28Occupational health and safety program management

A safety manager is drafting the program's inspection schedule and wants to allocate effort based on risk. Which approach best applies risk-based planning to routine workplace inspections?

  1. Delegate all inspections to external consultants on an annual basis
  2. Restrict inspections to areas that have never had a recorded incident
  3. Focus inspection frequency and depth on higher-risk areas and tasks Correct answer.
  4. Inspect every area on an identical monthly cycle regardless of hazard level

Explanation

Risk-based planning directs more frequent and more thorough inspections to areas and tasks with higher hazard potential, where failures are most likely to cause serious harm. Uniform schedules or inspections limited to low-incident areas ignore relative risk.

Question 29Occupational health and safety program management

A program coordinator is designing the process for investigating incidents. Which practice best supports identifying underlying program weaknesses rather than only the immediate cause?

  1. Assigning the investigation to the person whose department had the incident
  2. Interviewing only the injured worker and closing the file once the immediate act is named
  3. Reviewing related procedures, training records, and prior similar events alongside the sequence of events Correct answer.
  4. Limiting the investigation to events that resulted in lost-time injury

Explanation

Effective investigations look beyond the immediate act to contributory factors such as procedures, training, supervision, and prior similar events, which reveal program weaknesses. Narrow or self-assigned investigations tend to stop at the immediate cause.

Question 30Occupational health and safety program management

A company wants to verify that its safety program is performing as intended. It currently tracks only injury rates. Which set of indicators best complements injury rates for evaluating program performance?

  1. The number of safety meetings held, counted without regard to attendance or content
  2. Leading indicators such as inspection completion, hazard correction timeliness, and training coverage Correct answer.
  3. The average tenure of the safety manager in the role
  4. The total number of workers employed at each site over the year

Explanation

Lagging indicators like injury rates show outcomes after harm occurs, so leading indicators that measure preventive activity and follow-through give earlier and more actionable evidence of program performance. Counting meetings without quality measures or tracking unrelated staffing data does not reflect program effectiveness.

Question 31Regulatory compliance and legislation

Under the general hierarchy applied in most occupational health and safety statutes, which instrument takes precedence over the others?

  1. A regulation made under the Act
  2. A code of practice incorporated by reference
  3. An Act of the legislature Correct answer.
  4. A guidance note issued by the regulator

Explanation

Legislation sits at the top of the hierarchy: an Act outranks regulations made under it, which in turn outrank codes of practice and guidance. Codes and guidance do not create duties of themselves unless a statute gives them legal effect.

Question 32Regulatory compliance and legislation

What is the standard legal meaning of the phrase 'so far as is reasonably practicable'?

  1. The employer must do whatever the regulator directs in a notice
  2. The duty is weighed against cost, time and trouble unless grossly disproportionate to the risk Correct answer.
  3. The employer must eliminate all risk regardless of cost
  4. The employer is excused whenever the risk is not obvious to a lay person

Explanation

The concept requires a weighing of risk against the sacrifice needed to control it, so that grossly disproportionate measures are not required. It is not a cost-free absolute duty nor a licence to ignore unrecognised risk.

Question 33Regulatory compliance and legislation

A worker is injured at work. Which party normally bears the cost of the statutory workers' compensation benefit?

  1. The injured worker through payroll deductions
  2. The employer through insurance premiums or self-insurance Correct answer.
  3. The equipment manufacturer in all cases
  4. The public health system directly

Explanation

Workers' compensation is a no-fault scheme funded by employers, typically through premiums or approved self-insurance. The worker receives benefits without proving fault, and the scheme generally bars civil suits against the employer.

Question 34Regulatory compliance and legislation

Which best describes the primary purpose of a workplace joint health and safety committee under typical OHS legislation?

  1. To provide a forum where worker and employer representatives jointly address health and safety matters Correct answer.
  2. To negotiate wage rates for hazardous work
  3. To discipline workers who breach safety rules
  4. To replace the regulator's inspection function

Explanation

Joint committees bring worker and management representatives together to identify hazards, review incidents and recommend improvements. They are consultative and advisory bodies, not disciplinary or enforcement bodies.

Question 35Regulatory compliance and legislation

An employer becomes aware of a workplace incident that the legislation requires to be reported to the regulator. Within what general approach should the employer act?

  1. Report within the timeframe set in the legislation and preserve the scene until released Correct answer.
  2. Wait until the internal investigation is complete before notifying anyone
  3. Report at the next annual return
  4. Report only if the worker files a compensation claim

Explanation

Serious incidents trigger immediate or short statutory notification deadlines, and the scene must generally be preserved until the regulator authorises disturbance. Internal investigation runs alongside, not before, the notification duty.

Question 36Regulatory compliance and legislation

What does the internal responsibility system assume about workplace safety?

  1. That the regulator is present at every worksite
  2. That those who create and manage work are best placed to control its risks Correct answer.
  3. That insurance removes the need for prevention
  4. That workers alone are accountable for their own safety

Explanation

The internal responsibility system places the primary duty on those who direct and control the work, with workers also having duties to cooperate. It is a partnership model rather than reliance on external inspection.

Question 37Regulatory compliance and legislation

A regulation states that an employer shall provide fall protection where a worker may fall a specified distance. What is the legal character of this requirement?

  1. A recommendation subject to employer discretion
  2. A mandatory duty enforceable by the regulator Correct answer.
  3. Advisory guidance
  4. A voluntary industry standard

Explanation

Requirements framed as 'shall' in a regulation create mandatory, enforceable duties. Guidance and voluntary standards lack that binding character unless incorporated by reference.

Question 38Regulatory compliance and legislation

Which document typically sets out the regulator's interpretation of how to comply with a legal requirement without itself creating a new offence?

  1. A code of practice approved under the statute Correct answer.
  2. A supplier's safety data sheet
  3. A collective agreement
  4. The statute

Explanation

Approved codes of practice describe practical ways to meet legal duties and may be admissible as evidence of compliance or non-compliance. They do not themselves create offences beyond the underlying statute or regulation.

Question 39Regulatory compliance and legislation

What is the general effect of a stop-work order issued by a regulator?

  1. It transfers liability to the individual supervisor
  2. It is advisory and may be ignored if production pressure exists
  3. It legally compels cessation of the specified work until the order is complied with or lifted Correct answer.
  4. It permanently closes the business

Explanation

A stop-work order is an enforcement instrument that legally requires the affected activity to cease until the hazard is addressed or the order is rescinded. Ignoring it can attract penalties.

Question 40Regulatory compliance and legislation

Which principle underlies the right of workers to refuse work they believe is unsafe?

  1. Workers may refuse work only after an injury occurs
  2. Workers may refuse any task they dislike
  3. Workers may refuse work only with union approval
  4. Workers may refuse work where they have reasonable grounds to believe it is dangerous Correct answer.

Explanation

The right to refuse is grounded in a reasonable belief of danger and is usually subject to an investigation and resolution process. It is not a general right of refusal or conditional on union involvement.

Question 41Regulatory compliance and legislation

An employer must assess the risk of a new chemical process. Which statutory concept most directly requires the employer to identify hazards before work begins?

  1. The duty to display a licence
  2. The duty to conduct a risk assessment Correct answer.
  3. The duty to provide parking
  4. The duty to keep payroll records

Explanation

Risk assessment duties require employers to identify hazards and evaluate risks before introducing or changing work. The other items are unrelated administrative obligations.

Question 42Regulatory compliance and legislation

What is the usual legal status of a safety data sheet supplied with a hazardous product?

  1. It is a contract between supplier and worker
  2. It provides hazard, handling and emergency information that supports compliance Correct answer.
  3. It replaces the need for a workplace risk assessment
  4. It is optional and may be discarded on receipt

Explanation

Safety data sheets convey hazard and safe-handling information that employers use to inform assessments, training and controls. They supplement, but do not replace, the employer's own risk assessment.

Question 43Regulatory compliance and legislation

Which body typically has the authority to prosecute an employer for a breach of occupational health and safety legislation?

  1. The joint health and safety committee
  2. The workers' compensation insurer
  3. The regulator or public prosecutor Correct answer.
  4. The equipment supplier

Explanation

Enforcement and prosecution rest with the regulator or the public prosecuting authority, not with workplace committees or insurers. Committees may recommend but cannot lay charges.

Question 44Regulatory compliance and legislation

What does 'due diligence' generally require of a corporate officer in an OHS prosecution?

  1. Delegation of all safety duties to workers
  2. Proof that no incident has ever occurred
  3. Evidence of reasonable steps taken to prevent the offence Correct answer.
  4. A signed statement denying knowledge

Explanation

A due diligence defence requires the accused to show reasonable steps were taken to prevent the contravention, such as establishing and monitoring systems. It is about proactive effort, not a clean incident record.

Question 45Regulatory compliance and legislation

Which statement best captures how the general duty clause operates in OHS statutes?

  1. It applies only to construction sites
  2. It imposes a broad obligation to protect health and safety, filling gaps left by specific rules Correct answer.
  3. It lists every specific hazard an employer must control
  4. It overrides all specific regulations

Explanation

The general duty clause establishes a broad, overarching obligation that covers hazards not addressed by specific provisions. Specific regulations supplement and particularise it rather than being overridden by it.

Question 46Regulatory compliance and legislation

A worker is exposed to a substance with a regulated occupational exposure limit. What does the limit generally represent?

  1. An airborne concentration that should not be exceeded over the defined averaging period Correct answer.
  2. The maximum amount that may be stored on site
  3. A guaranteed safe level for all workers
  4. A recommended target with no legal effect

Explanation

Occupational exposure limits set airborne concentrations not to be exceeded over a defined reference period, and employers must control exposure accordingly. They are not guarantees of safety for every individual.

Question 47Regulatory compliance and legislation

Which is the most accurate description of the duty to accommodate a worker's disability in the safety context?

  1. Accommodation always means removing all physical hazards
  2. The worker must accept any accommodation offered
  3. The employer must consider accommodation to the point of undue hardship Correct answer.
  4. Accommodation is unnecessary if a policy applies to everyone equally

Explanation

Human rights duties require reasonable accommodation to the point of undue hardship, balancing safety with the worker's needs. Neutral policies can still be discriminatory if they adversely affect a protected group.

Question 48Regulatory compliance and legislation

What is the usual function of a work refusal investigation involving a health and safety representative?

  1. To impose discipline on the refusing worker
  2. To determine whether there are reasonable grounds for the refusal and to resolve it Correct answer.
  3. To replace the regulator permanently
  4. To set the worker's future pay rate

Explanation

The investigation examines whether reasonable grounds exist and seeks resolution, often with worker representation present. It is not a disciplinary or wage-setting process.

Question 49Regulatory compliance and legislation

Which best explains why OHS legislation often requires employers to provide information, instruction and supervision?

  1. To satisfy insurers only
  2. To ensure workers can perform their duties safely and understand the hazards they face Correct answer.
  3. To reduce the need for engineering controls
  4. To shift responsibility for safety entirely onto workers

Explanation

Information, instruction and supervision equip workers to recognise and manage hazards, and they complement rather than replace engineering controls. Responsibility remains shared, with the employer retaining primary control.

Question 50Regulatory compliance and legislation

What is the typical legal effect of a compliance order (as distinct from a stop-work order)?

  1. It imposes a criminal record automatically
  2. It requires the employer to remedy a contravention within a stated period Correct answer.
  3. It cancels all worker rights
  4. It immediately shuts the entire operation

Explanation

A compliance order directs the employer to correct a contravention within a specified timeframe. It differs from a stop-work order, which halts activity immediately, and does not itself create a criminal record.
