Question 1OSH Legislation, Regulatory Framework and OSHAD System Requirements

Under the OSHAD framework, which entity is primarily responsible for issuing and maintaining the emirate-level OSH regulatory requirements that registered entities must follow?

  1. The individual contracting company's safety department
  2. The employee welfare committee
  3. The OSHAD Sector Regulatory Authority Correct answer.
  4. The equipment supplier's technical division

Explanation

OSHAD operates as a framework in which a Sector Regulatory Authority issues and maintains the regulatory requirements for entities within its sector. Registered entities are then obligated to comply with those requirements. Company departments and suppliers do not create regulatory requirements.

Question 2OSH Legislation, Regulatory Framework and OSHAD System Requirements

In the OSHAD system, what is the primary purpose of an OSH Risk Register maintained by a registered entity?

  1. To track the company's annual financial expenditure on PPE
  2. To list the names of employees who have reported to work late
  3. To record identified hazards, associated risks and their controls and status Correct answer.
  4. To document the minutes of every toolbox talk held on site

Explanation

The risk register is the entity's central record of identified hazards, the assessed risk, the controls applied, and the current status of each risk. It supports prioritisation and monitoring of risk treatment. Financial records, attendance and meeting minutes are separate administrative documents.

Question 3OSH Legislation, Regulatory Framework and OSHAD System Requirements

A registered entity introduces a new chemical into its warehouse. Which OSHAD-aligned action should be taken before the chemical is stored and used?

  1. Update the hazard identification and risk assessment to include the new chemical and its controls Correct answer.
  2. Inform only the warehouse supervisor verbally
  3. Rely on the supplier to manage all on-site risks
  4. Wait until the next annual audit to record the change

Explanation

Any new hazard, including a new chemical, must be incorporated into hazard identification and risk assessment before work begins. Controls such as SDS review, storage requirements and exposure precautions should be defined at that stage. Deferring to an audit or relying on the supplier leaves the risk uncontrolled.

Question 4OSH Legislation, Regulatory Framework and OSHAD System Requirements

Which document in the OSHAD framework typically sets out an entity's OSH policy, objectives, responsibilities and arrangements in an integrated form?

  1. The employee's personal CV
  2. The OSH Management System manual or equivalent documented system Correct answer.
  3. The purchase order for safety footwear
  4. The fire extinguisher inspection tag

Explanation

An OSH management system manual documents the policy, objectives, roles and arrangements that form the entity's OSH management system. It is the integrating document that other procedures reference. Inspection tags, CVs and purchase orders are transactional records.

Question 5OSH Legislation, Regulatory Framework and OSHAD System Requirements

An OSHAD-registered entity is planning to contract a third party for high-risk work. What is the most appropriate OSHAD-aligned requirement to place on the contractor?

  1. Demonstrate OSH competence and comply with the entity's OSH requirements before work starts Correct answer.
  2. Submit their pricing schedule without any OSH information
  3. Provide only a verbal assurance on the first day of work
  4. Delegate all OSH responsibility to the client's reception desk

Explanation

Entities must ensure contractors are competent and that OSH requirements are communicated and met before work begins. This typically involves pre-qualification, agreed controls and coordination. Verbal assurances or pricing alone do not demonstrate control of risk.

Question 6OSH Legislation, Regulatory Framework and OSHAD System Requirements

What is the primary role of a Safety Case or equivalent major-hazard submission within the OSHAD framework?

  1. To summarise the company's marketing and sales strategy
  2. To record the holiday entitlement of site staff
  3. To replace all workplace inspections permanently
  4. To demonstrate that major accident hazards are identified and controlled to an acceptable level Correct answer.

Explanation

A safety case is a structured demonstration that major accident hazards have been identified, assessed and controlled, with management arrangements in place. It is a risk demonstration document, not a commercial or HR record. It complements, rather than replaces, routine inspection.

Question 7OSH Legislation, Regulatory Framework and OSHAD System Requirements

Which of the following best describes the OSHAD requirement for incident reporting and investigation?

  1. Near misses are excluded from all reporting systems
  2. Incidents are reported, recorded and investigated to identify causes and prevent recurrence Correct answer.
  3. Incidents are investigated only if the insurer requests it
  4. Only incidents that result in lost time are recorded

Explanation

OSHAD-aligned systems require reporting, recording and investigation of incidents, including near misses, so that root causes are identified and corrective action prevents recurrence. Limiting reporting to lost-time cases or insurer requests misses learning opportunities.

Question 8OSH Legislation, Regulatory Framework and OSHAD System Requirements

An entity's risk assessment identifies a residual risk that remains high after controls. What does OSHAD-aligned practice require?

  1. Further risk reduction measures or a formal justification and authorisation for the residual risk Correct answer.
  2. No action, because controls have already been applied
  3. Transfer of the risk to employees through a signed waiver
  4. Immediate abandonment of the activity without any record

Explanation

Where residual risk remains high, the entity must either apply further controls or formally justify and authorise the residual risk at an appropriate level. Simply stopping without review or doing nothing is not acceptable. Employees cannot waive their employer's duty of care.

Question 9OSH Legislation, Regulatory Framework and OSHAD System Requirements

Which statement best reflects the OSHAD principle of worker consultation and participation?

  1. Workers are consulted only when a regulator visits the site
  2. Workers are consulted on OSH matters that affect them and can participate in risk control Correct answer.
  3. Workers have no role in OSH because it is a management function
  4. Workers are informed of decisions only after they are fully implemented

Explanation

OSHAD-aligned systems require consultation and participation of workers on OSH matters affecting them, including risk assessment and control. Participation improves hazard identification and control effectiveness. Consultation limited to regulator visits or post-decision information does not meet the principle.

Question 10OSH Legislation, Regulatory Framework and OSHAD System Requirements

A registered entity must maintain OSH records. Which approach best meets OSHAD-aligned record-keeping expectations?

  1. Records are maintained only when a complaint is received
  2. Records are kept only in employees' personal memory
  3. Records are legible, dated, retrievable and retained for a defined period Correct answer.
  4. Records are destroyed as soon as the task is completed

Explanation

OSH records must be identifiable, legible, dated, retrievable and retained for a defined period so that compliance and control can be demonstrated. Relying on memory or destroying records immediately undermines traceability. Records kept only on complaint are incomplete.

Question 11OSH Legislation, Regulatory Framework and OSHAD System Requirements

What is the purpose of an OSHAD audit of a registered entity?

  1. To verify that the OSH management system conforms to requirements and is effectively implemented Correct answer.
  2. To replace the need for internal inspections
  3. To assign blame to individual workers for past incidents
  4. To calculate the company's annual profit margin

Explanation

An OSH audit verifies conformity of the management system with requirements and its effective implementation. It is a systematic, evidence-based check, not a financial exercise or a blame process. Audits complement, but do not replace, routine inspection.

Question 12OSH Legislation, Regulatory Framework and OSHAD System Requirements

An entity identifies a legal requirement applicable to its operations that it is not currently meeting. What is the OSHAD-aligned response?

  1. Ignore the gap because the law changes frequently
  2. Wait for an inspector to issue a penalty before acting
  3. Record the gap, set corrective action with responsibility and a deadline, and monitor closure Correct answer.
  4. Delegate the gap to a contractor with no follow-up

Explanation

Compliance obligations require the entity to identify applicable legal requirements, evaluate compliance, and address gaps through corrective action with ownership and deadlines. Ignoring the gap or waiting for enforcement is not compliant. Delegation without follow-up does not discharge the duty.

Question 13OSH Legislation, Regulatory Framework and OSHAD System Requirements

Which of the following is the most appropriate way for an entity to communicate OSHAD requirements to a multilingual workforce?

  1. Provide information and training in a language and format workers can understand Correct answer.
  2. Provide documents only to the site manager
  3. Rely solely on English-language posters in a back office
  4. Assume workers will learn requirements informally on the job

Explanation

OSH information and training must be provided in a form and language that workers understand so that requirements are actually communicated. Posters in an inaccessible location or documents given only to a manager do not reach the workforce. Informal learning is not a reliable substitute.

Question 14OSH Legislation, Regulatory Framework and OSHAD System Requirements

What does the OSHAD concept of 'competence' most directly require of a person assigned to a safety-critical task?

  1. Only a long period of general employment with the company
  2. The necessary training, knowledge, experience and demonstrated ability to perform the task safely Correct answer.
  3. Only the lowest available wage rate for the role
  4. Only a signed declaration that the person feels confident

Explanation

Competence combines training, knowledge, experience and demonstrated ability relevant to the task. Self-declaration of confidence or general tenure alone does not evidence competence. Wage rate is irrelevant to competence.

Question 15OSH Legislation, Regulatory Framework and OSHAD System Requirements

An entity's OSH objectives are set but no indicators are tracked. Which OSHAD-aligned improvement is most appropriate?

  1. Remove the objectives because they cannot be measured
  2. Define measurable OSH performance indicators with targets and review them periodically Correct answer.
  3. Add more objectives without any measurement
  4. Report objectives only in the annual financial statement

Explanation

Objectives should be supported by measurable performance indicators with targets and periodic review so progress can be evaluated and corrective action taken. Removing objectives or adding unmeasured ones defeats the purpose. OSH objectives do not belong in financial statements.

Question 16OSH Legislation, Regulatory Framework and OSHAD System Requirements

Which of the following best describes a 'permit to work' system in an OSHAD-aligned entity?

  1. A document that permanently authorises all future high-risk work
  2. A purchase requisition for tools
  3. An informal note passed between workers
  4. A formal authorisation process for high-risk work that verifies controls before work starts Correct answer.

Explanation

A permit to work is a formal, documented authorisation that verifies specified controls are in place before high-risk work begins. It is task- and time-specific, not a blanket or informal authorisation. Purchase requisitions are procurement documents.

Question 17OSH Legislation, Regulatory Framework and OSHAD System Requirements

An entity wants to demonstrate continual improvement under OSHAD. Which approach is most appropriate?

  1. Repeat the same plan each year without review
  2. Only react to incidents after they occur
  3. Reduce the scope of the OSH system each year
  4. Use audit findings, incident trends and performance data to set and review improvement actions Correct answer.

Explanation

Continual improvement relies on using audit findings, incident trends and performance data to identify and review improvement actions. Repeating plans without review or only reacting to incidents does not demonstrate improvement. Reducing system scope is regression, not improvement.

Question 18OSH Legislation, Regulatory Framework and OSHAD System Requirements

Which of the following best describes the OSHAD expectation for emergency preparedness in a registered entity?

  1. Emergency plans are written once and never tested
  2. Drills are conducted only after an emergency occurs
  3. Emergency plans, resources and drills are established, tested and reviewed Correct answer.
  4. Emergency response is left entirely to individual employees

Explanation

Emergency preparedness requires documented plans, adequate resources and periodic drills that are tested and reviewed for effectiveness. Plans that are never tested or left to individuals are unlikely to work in a real event. Drills must be proactive, not after the fact.

Question 19OSH Legislation, Regulatory Framework and OSHAD System Requirements

A registered entity is unsure whether a new activity falls within its OSHAD registration scope. What is the most appropriate action?

  1. Assess the activity against the applicable OSHAD requirements and seek clarification from the relevant authority Correct answer.
  2. Ask a supplier to decide on the entity's behalf
  3. Assume the activity is out of scope and do nothing
  4. Proceed without assessment because the activity is new

Explanation

Where scope is uncertain, the entity should assess the activity against applicable requirements and seek clarification from the relevant regulatory authority. Proceeding without assessment or assuming exclusion creates uncontrolled risk and potential non-compliance. Suppliers cannot decide scope for the entity.

Question 20OSH Legislation, Regulatory Framework and OSHAD System Requirements

Which of the following best describes the purpose of an OSHAD inspection (as distinct from an audit)?

  1. To check physical conditions and work practices against defined standards at a point in time Correct answer.
  2. To calculate the cost of safety equipment
  3. To determine employee salary increments
  4. To verify the entire management system's conformity over a period

Explanation

An inspection checks physical conditions and work practices against defined standards at a point in time, whereas an audit evaluates the broader management system's conformity. Cost calculation and salary decisions are unrelated to inspection.

Question 21OSH Legislation, Regulatory Framework and OSHAD System Requirements

What is the most appropriate OSHAD-aligned approach to managing changes in plant or process that could affect OSH?

  1. Apply a management-of-change process that assesses OSH impacts before implementation Correct answer.
  2. Implement the change first and assess impacts afterwards
  3. Assume changes are safe if they are cheaper
  4. Assess impacts only if an incident occurs

Explanation

A management-of-change process assesses OSH impacts and defines controls before changes are implemented. Implementing first and assessing later exposes workers to unmanaged risk. Incident-driven assessment is too late, and cost is not a measure of safety.

Question 22OSH Legislation, Regulatory Framework and OSHAD System Requirements

Which of the following best describes the OSHAD expectation for the provision of personal protective equipment (PPE)?

  1. PPE replaces the need for engineering controls in all cases
  2. PPE is charged to workers to encourage careful use
  3. PPE is provided free of charge, selected for the risk, and used as a last line of defence Correct answer.
  4. PPE is chosen without reference to the hazard

Explanation

PPE should be provided free of charge, selected to match the identified risk, and used as the last line of defence after higher-order controls. Charging workers or ignoring the hazard undermines effectiveness, and PPE does not replace engineering controls where these are reasonably practicable.

Question 23OSH Legislation, Regulatory Framework and OSHAD System Requirements

An entity's risk assessment was completed three years ago and no review has occurred despite new equipment and staff. What is the most appropriate OSHAD-aligned action?

  1. Continue using the old assessment until an incident occurs
  2. Review and update the risk assessment to reflect current conditions Correct answer.
  3. Discard the assessment entirely
  4. Ask the newest employee to write a new assessment alone

Explanation

Risk assessments must be reviewed and updated when conditions change, such as new equipment or personnel, and periodically. Continuing with an outdated assessment leaves new hazards uncontrolled. Discarding it loses valuable information, and a new employee alone lacks the necessary knowledge.

Question 24OSH Legislation, Regulatory Framework and OSHAD System Requirements

Which of the following best describes the hierarchy of controls as applied in OSHAD-aligned risk management?

  1. PPE, administrative controls, engineering controls, substitution, then elimination
  2. Random selection of controls based on cost
  3. Administrative controls only, applied in any order
  4. Elimination, substitution, engineering controls, administrative controls, then PPE Correct answer.

Explanation

The hierarchy of controls ranks measures from most to least effective: elimination, substitution, engineering controls, administrative controls and finally PPE. Applying controls in reverse order or at random is not consistent with the hierarchy and generally produces weaker protection.

Question 25OSH Legislation, Regulatory Framework and OSHAD System Requirements

A regulator requests evidence of an entity's OSH performance over the past year. Which combination best demonstrates OSHAD-aligned evidence?

  1. Only the number of employees on site
  2. Risk assessments, inspection and audit records, incident data and training records Correct answer.
  3. Only a verbal summary from the site manager
  4. Only the company's marketing brochure

Explanation

Evidence of OSH performance is demonstrated through documented records such as risk assessments, inspection and audit results, incident data and training records. Verbal summaries, marketing material and headcount alone do not evidence OSH performance.

Question 26OSH Legislation, Regulatory Framework and OSHAD System Requirements

Under the OSHAD framework, who within a registered entity carries the ultimate accountability for establishing and maintaining the OSH management system?

  1. The designated OSH officer alone
  2. The external consultant who prepared the documentation
  3. The senior management or owner of the entity Correct answer.
  4. The workforce safety committee collectively

Explanation

OSHAD places accountability for the OSH management system at the top of the organisation, meaning senior management or the owner must establish, resource and maintain it. Operational duties may be delegated, but accountability is not transferred by delegation.

Question 27OSH Legislation, Regulatory Framework and OSHAD System Requirements

An entity is deciding how to structure its OSHAD documentation. Which approach best reflects OSHAD expectations for documented information?

  1. Keep all OSH information informal so it can be updated quickly
  2. Restrict OSH documents to the senior management team only
  3. Maintain controlled documents that are current, accessible and approved Correct answer.
  4. Document only what the regulator has explicitly requested in writing

Explanation

OSHAD expects documented information to be controlled: approved, current, identifiable and available to those who need it. This supports consistency, traceability and effective implementation of the management system.

Question 28OSH Legislation, Regulatory Framework and OSHAD System Requirements

A registered entity operates a facility where a contractor will perform hot work. Which arrangement best aligns with OSHAD expectations for contractor management?

  1. Delegate all supervision of the contractor to the contractor's own staff
  2. Rely on the contractor's own procedures without any entity involvement
  3. Define and communicate OSH requirements and controls before work begins Correct answer.
  4. Allow work to start and address any issues found during routine inspection

Explanation

OSHAD expects the host entity to define, communicate and verify OSH requirements for contractors before work starts, including coordination of hazards and controls. This prevents gaps where each party assumes the other is managing a risk.

Question 29OSH Legislation, Regulatory Framework and OSHAD System Requirements

During a site walk, a worker reports that a guard has been removed from a machine. The supervisor's response is to record it in the OSH log and arrange repair. Which OSHAD-aligned action should accompany this?

  1. Take interim measures to prevent access to the hazard until repaired Correct answer.
  2. Close the entry once the repair request has been raised
  3. Reassign the reporting worker to another area
  4. Wait for the next scheduled audit to review the finding

Explanation

When a hazard is identified, OSHAD-aligned practice requires interim controls to protect people until the hazard is eliminated or the permanent fix is complete. Recording and arranging repair are necessary but do not by themselves protect workers in the meantime.

Question 30OSH Legislation, Regulatory Framework and OSHAD System Requirements

An entity's OSHAD management system has defined roles, but several safety-critical duties are assigned to staff who have not been trained for them. Which analysis best describes the underlying system weakness?

  1. The system has too many documented procedures
  2. The system relies on a single OSH officer
  3. The system does not link competence requirements to assigned duties Correct answer.
  4. The system lacks a defined organisational chart

Explanation

OSHAD-aligned systems require that people assigned to safety-critical tasks are competent for those tasks. Where duties are assigned without matching competence, the gap is in how the system links role requirements to verified competence, not in documentation volume or structure.

Question 31Hazard Identification, Risk Assessment and Risk Management

In the hierarchy of controls, which control measure is considered the most effective for reducing risk?

  1. Administrative controls
  2. Elimination Correct answer.
  3. Engineering controls
  4. Personal protective equipment

Explanation

The hierarchy of controls ranks measures from most to least effective. Elimination removes the hazard entirely, making it the most reliable control. Engineering, administrative, and PPE controls are progressively less effective because they rely on human behavior or barriers that can fail.

Question 32Hazard Identification, Risk Assessment and Risk Management

What is the primary purpose of a hazard identification and risk assessment (HIRA) process?

  1. To replace workplace inspections
  2. To satisfy insurance requirements
  3. To systematically identify hazards and evaluate risks to determine controls Correct answer.
  4. To assign blame for past incidents

Explanation

HIRA is a proactive process to find hazards, assess the likelihood and severity of harm, and decide on appropriate controls. It is not about blame, insurance, or replacing inspections; it informs risk management decisions.

Question 33Hazard Identification, Risk Assessment and Risk Management

Which of the following is an example of a physical hazard in the workplace?

  1. Excessive noise Correct answer.
  2. Bullying
  3. Poor lighting
  4. Repetitive lifting

Explanation

Physical hazards include energy sources such as noise, vibration, extreme temperatures, and radiation. Poor lighting is often classified as an environmental or ergonomic hazard, bullying is a psychosocial hazard, and repetitive lifting is an ergonomic hazard.

Question 34Hazard Identification, Risk Assessment and Risk Management

What does the term 'risk' most accurately describe in the context of OSH?

  1. The number of hazards present
  2. The probability that a hazard will cause harm
  3. The cost of implementing controls
  4. The combination of likelihood and severity of harm Correct answer.

Explanation

Risk is commonly defined as the combination of the likelihood of an occurrence and the severity of the harm that could result. It is not merely probability alone, nor a count of hazards or a financial measure.

Question 35Hazard Identification, Risk Assessment and Risk Management

Which risk assessment matrix format is most common for prioritizing risks?

  1. A pie chart of incident types
  2. A flow chart of tasks
  3. A 5x5 matrix with likelihood and consequence axes Correct answer.
  4. A bar chart of injury rates

Explanation

A likelihood-consequence matrix, often 5x5, is widely used to rate and prioritize risks by combining probability and severity. Charts and flow diagrams serve other purposes and do not directly prioritize risk.

Question 36Hazard Identification, Risk Assessment and Risk Management

What is the first step in a typical risk management process?

  1. Record findings
  2. Monitor and review
  3. Identify hazards Correct answer.
  4. Implement controls

Explanation

Risk management begins with hazard identification, which establishes what could cause harm. Only after hazards are identified can risks be assessed, controls implemented, and monitoring conducted.

Question 37Hazard Identification, Risk Assessment and Risk Management

Which document typically records the findings of a risk assessment and the controls to be applied?

  1. Training log
  2. Material safety data sheet
  3. Risk register Correct answer.
  4. Incident report

Explanation

A risk register lists identified hazards, their assessed risk levels, and the controls and responsible persons. MSDS provide chemical hazard information, incident reports document events, and training logs record attendance.

Question 38Hazard Identification, Risk Assessment and Risk Management

What is the purpose of a preliminary hazard analysis (PHA)?

  1. To determine insurance premiums
  2. To provide a detailed quantitative risk estimate
  3. To replace a full risk assessment
  4. To identify hazards early in a project or system lifecycle Correct answer.

Explanation

A PHA is a qualitative method used early in design or planning to identify potential hazards and prioritize further analysis. It is not a detailed quantitative tool and does not replace a full risk assessment.

Question 39Hazard Identification, Risk Assessment and Risk Management

A worker is exposed to a chemical with a workplace exposure limit (WEL). What does the WEL represent?

  1. The maximum duration of exposure allowed per shift
  2. The maximum amount that can be stored on site
  3. The minimum concentration required for detection
  4. The maximum concentration of the substance that should not be exceeded in workplace air Correct answer.

Explanation

A WEL is an airborne concentration limit intended to protect workers from adverse health effects. It is not about storage quantity, detection thresholds, or exposure duration directly.

Question 40Hazard Identification, Risk Assessment and Risk Management

Which of the following best describes a 'residual risk'?

  1. The risk before any controls are applied
  2. The risk of a control failing
  3. The risk that cannot be identified
  4. The risk remaining after controls have been implemented Correct answer.

Explanation

Residual risk is what remains after existing or planned controls are taken into account. It is used to decide whether further controls are needed.

Question 41Hazard Identification, Risk Assessment and Risk Management

In a risk assessment, what does 'likelihood' refer to?

  1. The severity of the harm that could occur
  2. The duration of exposure
  3. The probability that a hazardous event will occur Correct answer.
  4. The number of people exposed

Explanation

Likelihood is the chance or probability that a hazardous event will happen. Severity relates to the degree of harm, while exposure factors such as number of people and duration influence likelihood and consequence but are not the definition of likelihood.

Question 42Hazard Identification, Risk Assessment and Risk Management

A task involves manual handling of heavy boxes. Which risk assessment approach is most appropriate?

  1. A task-specific manual handling risk assessment Correct answer.
  2. A fire risk assessment
  3. A COSHH assessment
  4. A generic risk assessment for the whole site

Explanation

Manual handling risks are best assessed using a task-specific approach that examines the load, posture, repetition, and environment. Generic, fire, or chemical assessments do not address the specific ergonomic hazards of the task.

Question 43Hazard Identification, Risk Assessment and Risk Management

Which of the following is a qualitative risk assessment method?

  1. Fault tree analysis
  2. Event tree analysis
  3. Layer of protection analysis
  4. Risk matrix Correct answer.

Explanation

A risk matrix uses descriptive categories (e.g., low, medium, high) for likelihood and consequence, making it qualitative or semi-quantitative. Fault tree, event tree, and LOPA are quantitative or semi-quantitative techniques.

Question 44Hazard Identification, Risk Assessment and Risk Management

When should a risk assessment be reviewed?

  1. At fixed intervals and when there are changes to the process or workforce Correct answer.
  2. Once every five years regardless of changes
  3. Only when requested by a regulator
  4. Only when an incident occurs

Explanation

Risk assessments should be reviewed periodically and whenever there are changes such as new equipment, processes, or personnel, or after incidents. A fixed five-year rule or incident-only review is insufficient.

Question 45Hazard Identification, Risk Assessment and Risk Management

What is the primary role of worker consultation in the risk assessment process?

  1. To shift legal liability to workers
  2. To ensure workers' knowledge of the task is used to identify hazards and controls Correct answer.
  3. To reduce the need for documentation
  4. To speed up the assessment by skipping steps

Explanation

Workers often have detailed knowledge of how tasks are actually performed and can identify hazards that managers might miss. Consultation improves the quality of the assessment and the acceptability of controls; it does not transfer liability or bypass steps.

Question 46Hazard Identification, Risk Assessment and Risk Management

Which of the following is an example of an engineering control for a noisy machine?

  1. Enclosing the machine in a soundproof booth Correct answer.
  2. Rotating workers to limit exposure time
  3. Providing hearing protection
  4. Posting warning signs

Explanation

Engineering controls modify the equipment or environment to reduce hazard exposure at the source, such as soundproof enclosures. PPE, signage, and administrative rotation are less effective and do not reduce noise at the source.

Question 47Hazard Identification, Risk Assessment and Risk Management

A risk assessment identifies a hazard with a risk rating of 'high'. According to the hierarchy of controls, what should be considered first?

  1. Whether training can be updated
  2. Whether the hazard can be eliminated Correct answer.
  3. Whether warning signs can be posted
  4. Whether PPE can be provided

Explanation

The hierarchy of controls requires considering elimination first, as removing the hazard is the most effective risk reduction. PPE, training, and signage are lower-order controls to be considered only after higher-order options.

Question 48Hazard Identification, Risk Assessment and Risk Management

What does ALARP stand for in risk management?

  1. All Levels Are Risk Planned
  2. As Low As Risk Permits
  3. As Low As Reasonably Practicable Correct answer.
  4. Assess, Limit, Avoid, Report, Prevent

Explanation

ALARP means reducing risk to a level that is as low as reasonably practicable, balancing risk reduction against cost and effort. The other options are not recognized OSH terms.

Question 49Hazard Identification, Risk Assessment and Risk Management

Which of the following best describes a 'dynamic risk assessment'?

  1. A quantitative assessment using fault trees
  2. An assessment performed only by external consultants
  3. A formal assessment conducted annually
  4. An ongoing assessment of changing conditions during work Correct answer.

Explanation

A dynamic risk assessment is performed in real time as conditions change, allowing workers to identify and respond to new hazards. It is not necessarily annual, quantitative, or outsourced.

Question 50Hazard Identification, Risk Assessment and Risk Management

In the context of risk assessment, what is a 'hazard'?

  1. The severity of an injury
  2. The likelihood of harm occurring
  3. The control measure applied to reduce risk
  4. A source or situation with the potential to cause harm Correct answer.

Explanation

A hazard is anything with the potential to cause harm, such as a substance, process, or situation. Likelihood and severity are components of risk, and controls are measures to reduce risk.
