UNISA HRM3701 Exam Notes: Ergonomics and Workplace Hazard Identification for UNISA HR Professionals

Ergonomics and workplace hazard identification are core parts of employee wellness, injury prevention, and legal compliance in South African higher education workplaces. For UNISA HR professionals, these topics are especially important because the institution’s work environment includes offices, archives, libraries, laboratories, service centres, study hubs, and remote work arrangements that expose employees to different physical, psychosocial, and environmental risks. Strong knowledge of ergonomics and hazard identification helps HR support safer work design, better attendance, reduced compensation claims, and a healthier academic and administrative workforce.

1. Ergonomics in the UNISA Workplace Context

Ergonomics is the science of fitting the work to the worker rather than forcing the worker to fit the work. In a university setting such as UNISA, this principle applies to lecturers working long hours at computers, administrators handling repetitive clerical tasks, call centre staff using headsets, cleaners performing manual handling tasks, and technical employees operating or moving equipment. The goal is to reduce strain, prevent injury, and improve performance by designing workstations, tasks, tools, and schedules around human capabilities and limitations.

For HR professionals, ergonomics is not a narrow “office chair” issue. It is a practical management discipline that links employee wellbeing, productivity, absenteeism, disability prevention, and legal compliance. At UNISA, where work may be distributed across campuses, regional service points, and home offices, ergonomic risks are not identical from one job family to another. An effective HR response must therefore be role-specific and evidence-based.

1.1 Core ergonomic principles

The central ergonomic principles relevant to UNISA HR practice include the following:

Neutral posture
The body should be positioned so that joints are not excessively bent, twisted, or extended. A neutral spine, relaxed shoulders, elbows close to the body, and wrists kept straight reduce musculoskeletal stress.
Fit between worker and task
Workstations and tools should be adjustable to accommodate differences in height, reach, strength, and mobility. A single “standard” setup often fails to serve all employees.
Reduction of repetition and force
Repetitive keystrokes, scanning, filing, lifting, and carrying can cause cumulative trauma. Where possible, repetition should be reduced through automation, scheduling, or rotation.
Adequate rest and recovery
Static postures and repetitive tasks become more harmful when performed for long uninterrupted periods. Micro-breaks, job rotation, and workload planning are part of ergonomic control.
Visibility and accessibility
Important materials, controls, and screens should be placed within comfortable reach and line of sight. Poor layout causes unnecessary stretching, bending, or head turning.
Compatibility with the work environment
Lighting, noise, temperature, ventilation, and space all affect how a worker interacts with the task. Ergonomics therefore overlaps with environmental health and safety.

These principles matter because many ergonomic injuries develop slowly. Unlike a sudden fall or electric shock, a musculoskeletal disorder may begin as mild neck discomfort and progress to chronic pain, reduced productivity, and lost work time if not addressed early.

1.2 Why ergonomics matters for UNISA HR professionals

HR professionals are often the first institutional actors to notice patterns such as recurring sick leave, complaints about pain, reduced concentration, or requests for accommodations. They may not perform technical ergonomic assessments themselves, but they must know how to identify when a problem exists, escalate it appropriately, and ensure that corrective action is documented.

At UNISA, ergonomic management has several practical benefits:

Reduced absenteeism: employees with poorly designed workstations are more likely to experience back pain, wrist pain, headaches, and fatigue.
Improved retention: employees who feel physically supported are less likely to burn out or seek transfers.
Better service delivery: staff who work comfortably can respond more effectively to students and colleagues.
Lower compensation and medical costs: preventing injury is cheaper than treating repetitive strain injuries or occupational back injuries.
Fair accommodation practices: employees with disabilities or temporary restrictions can be supported through reasonable adjustments.
Compliance with occupational health duties: employer obligations under South African occupational health and safety principles require risk management, not only reactive treatment.

A common mistake is to treat ergonomics as a personal preference issue, as though one employee’s neck pain is merely due to “bad posture.” In reality, ergonomic risk is usually created by a combination of factors: workstation design, software systems, workload pressure, poor scheduling, and lack of awareness. HR professionals should therefore think systemically.

1.3 Ergonomic risk factors in higher education administration

UNISA’s administrative and academic environments include several recurring ergonomic risk factors.

Prolonged sitting

Many employees spend most of the day seated at computers, in meetings, or reviewing documents. Long periods of sitting can contribute to lower back pain, reduced circulation, and stiffness, especially when chairs are not adjustable or employees slouch forward to view screens.

Repetitive computer use

Data capture, email management, student support work, spreadsheet tasks, and online administration all require repeated hand and finger movements. Continuous mouse use and keyboarding can contribute to hand, wrist, forearm, and shoulder strain.

Visual strain

Employees who spend long hours reading screens or documents may experience eye fatigue, blurred vision, headaches, and reduced concentration. Poor lighting, glare, or incorrect screen height increase the problem.

Manual handling

Not all UNISA work is digital. Employees may move boxes of files, stationery, books, or equipment. Lifting without proper technique or assistance can cause back injury and shoulder strain.

Poorly designed remote workspaces

Home offices vary widely. Some employees use kitchen tables, low couches, unstable chairs, or laptop-only setups. These conditions often encourage awkward postures and extend ergonomic risk beyond the formal workplace.

Psychosocial stress interacting with physical strain

High workload, tight deadlines, and emotional labour can intensify physical discomfort. A tense employee is more likely to adopt rigid postures, skip breaks, and work through warning signs of strain.

1.4 Ergonomic injury patterns commonly seen in office work

The most common ergonomic-related conditions relevant to university administration include:

Lower back pain caused by prolonged sitting, poor lumbar support, or awkward lifting
Neck pain caused by forward head posture or monitor placement that is too low or too high
Shoulder strain caused by elevated arms, poor mouse positioning, or repeated reaching
Wrist and hand discomfort caused by repetitive typing, excessive mouse use, or awkward keyboard height
Tendinitis and repetitive strain injuries caused by repeated actions without recovery time
Eye strain and headaches caused by glare, insufficient contrast, or excessive screen time
General fatigue caused by poor workstation layout, inadequate movement, and sustained concentration

These conditions are important to HR because they may not appear suddenly in incident registers. Instead, they show up in patterns: multiple sick notes, complaints during performance reviews, ergonomic accommodation requests, and reduced output from specific teams.

1.5 Ergonomics as part of inclusion and reasonable accommodation

In a diverse university workforce, ergonomic design supports inclusion. Employees may have different body sizes, pregnancy-related needs, chronic pain conditions, temporary injuries, or disabilities. If the workplace is designed for a narrow “average” worker, many employees are placed at risk. Adjustable chairs, monitor arms, footrests, document holders, and flexible work arrangements are not luxuries; they are practical tools that support equity.

HR professionals should treat ergonomic accommodation as a structured process:

Identify the limitation or complaint.
Determine the essential job functions.
Assess the barriers in the existing workstation or schedule.
Explore low-cost adjustments first.
Refer to occupational health or a qualified ergonomics assessor when needed.
Document the decision and review it after implementation.

The key point is that ergonomics and accommodation are connected. A well-designed workplace often prevents the need for formal accommodation, while a poor design increases disability-related barriers.

2. Workplace Hazard Identification: Concepts, Categories, and Practical Meaning

Workplace hazard identification is the process of finding sources of potential harm before they cause injury, illness, loss, or disruption. For UNISA HR professionals, hazard identification is a foundational safety skill because it supports incident prevention, risk assessment, and compliance with occupational health requirements. A hazard is anything with the potential to cause harm; risk is the likelihood that the hazard will cause harm and how severe that harm may be.

This distinction matters. For example, a loose cable in a corridor is a hazard. The risk becomes higher if the corridor is poorly lit, busy, or used by staff carrying boxes. HR professionals must understand not only what hazards exist, but how context influences the level of risk.

2.1 The main hazard categories relevant to UNISA

Workplace hazards can be grouped into several broad categories. Each category appears in university workplaces in different ways.

Hazard category	Typical examples in a university workplace	Possible harm
Physical hazards	Noise, heat, poor lighting, glare, slippery floors, unstable shelving	Burns, slips, trips, falls, eye strain, fatigue
Ergonomic hazards	Poor workstation setup, repetitive keyboarding, awkward lifting, poor posture	Back pain, neck pain, repetitive strain injuries
Chemical hazards	Cleaning agents, printer chemicals, laboratory substances	Skin irritation, respiratory issues, poisoning
Biological hazards	Flu exposure, mould, contaminated waste, body fluids	Infection, allergic reactions
Mechanical hazards	Faulty machinery, sharp edges, moving parts, malfunctioning lifts	Cuts, crush injuries, fractures
Electrical hazards	Damaged plugs, overloaded sockets, faulty wiring, unsafe extensions	Shock, burns, fire
Fire hazards	Blocked exits, overloaded circuits, flammable materials	Burns, smoke inhalation, fatalities
Psychosocial hazards	Violence, bullying, harassment, excessive workload, burnout	Anxiety, depression, stress-related illness
Environmental hazards	Extreme temperatures, poor ventilation, poor air quality	Discomfort, dehydration, respiratory distress

For HR purposes, the most visible hazards are not always the most important. A workplace may look tidy but still expose staff to high psychosocial risk or long-term ergonomic damage. Hazard identification must therefore be systematic rather than impressionistic.

2.2 Hazard identification versus hazard reporting

Hazard identification is the process of noticing and analysing hazards. Hazard reporting is the act of communicating them formally so that they can be controlled. HR professionals should understand both because employees may hesitate to report a concern, or may report it informally without using the correct channel. If hazard reporting systems are weak, risks remain hidden until an incident occurs.

Effective reporting should capture:

the location of the hazard
the date and time it was observed
the people exposed to it
the type of hazard
the immediate danger
any temporary control that was applied
who was notified
the follow-up action required

A recurring weakness in organizations is the assumption that “everyone knows about it.” In reality, known hazards are often tolerated because they have not yet caused serious harm. HR should help build a culture where reporting is routine and non-punitive.

2.3 Common hazard identification methods

UNISA HR professionals should be familiar with the following methods.

Walkthrough inspections

A walkthrough is a structured physical inspection of the workplace. It allows observers to identify hazards such as blocked walkways, poor lighting, trip hazards, overloaded sockets, unsafe storage, or unsuitable furniture. Walkthroughs are especially useful in offices, reception areas, archives, and support service spaces.

Checklists

Checklists ensure that key hazards are not overlooked. For ergonomic assessments, a checklist might ask whether chairs are adjustable, screens are at eye level, or footrests are available. For general hazards, it may include fire exits, first aid readiness, and housekeeping.

Employee reports and surveys

Employees often know where the hidden risks are. Surveys can reveal discomfort, frequent near misses, or recurring problems such as headaches, fatigue, or unsafe manual handling.

Incident and near-miss analysis

A near miss is an event that could have caused harm but did not. Repeated near misses, even without injuries, indicate that a hazard is active and controls may be inadequate.

Task analysis

This method examines a job step by step to identify where strain, exposure, or danger occurs. It is useful for manual handling, data capture work, stock movement, and laboratory or maintenance support tasks.

Consultation with specialists

Some hazards require input from occupational health practitioners, safety officers, ergonomists, or facility managers. HR should know when to refer rather than improvise.

2.4 Why hazard identification is often missed

Hazards remain unidentified for predictable reasons:

Normalization of risk: staff become accustomed to unsafe conditions and stop noticing them.
Low reporting confidence: employees may fear blame, delay, or being seen as difficult.
Lack of training: staff may not know what counts as a hazard.
Invisible hazards: stress, fatigue, poor posture, or poor indoor air quality are less obvious than spills or broken furniture.
Fragmented responsibility: HR, facilities, line managers, and safety representatives may each assume another unit is responsible.

The solution is a coordinated safety culture. HR can lead by making hazard identification part of induction, performance support, and manager training.

2.5 The link between hazard identification and risk control

Identifying a hazard is only the first step. The purpose is to reduce risk through appropriate controls. If a hazard is identified but not controlled, the process fails. HR professionals should therefore think in terms of the hierarchy of controls:

Elimination – remove the hazard entirely
Substitution – replace the hazard with a safer alternative
Engineering controls – isolate people from the hazard
Administrative controls – change work practices, schedules, or procedures
PPE – provide personal protective equipment as a last line of defence

In ergonomic and office settings, engineering and administrative controls are often more effective than PPE. A better chair, improved screen placement, job rotation, and break scheduling are usually more meaningful than advice to “sit correctly” alone.

3. Ergonomic Assessment and Hazard Identification in Practice

Practical assessment is where theory becomes useful. UNISA HR professionals need to recognise signs of ergonomic stress and unsafe conditions, gather information accurately, and initiate corrective action without delay. A disciplined assessment process prevents guesswork and improves consistency across departments.

3.1 A practical ergonomic assessment sequence

A structured ergonomic assessment can be carried out in six steps:

Identify the employee or task at issue
Determine whether the concern relates to a person, a specific workstation, a job role, or a whole unit.
Describe the task and environment
Document the frequency, duration, and nature of the task. Note the furniture, equipment, lighting, space, and workflow.
Observe posture and movement
Look for leaning, twisting, reaching, elevated shoulders, unsupported wrists, repeated bending, or static positions held for long periods.
Gather employee feedback
Ask where discomfort is felt, when it starts, what worsens it, and whether symptoms improve during rest or holidays.
Identify contributing hazards
Separate the underlying causes from the symptoms. For example, neck pain may result from a low monitor, poor chair height, and poor document placement rather than from one factor alone.
Recommend controls and review
Implement changes, monitor whether symptoms or hazards improve, and adjust if necessary.

This sequence is important because employees often describe the pain rather than the risk. HR must translate symptoms into actionable findings.

3.2 Observable signs of ergonomic problems

Some signs are visible in the workplace; others appear in employee behaviour or records.

Environmental and workstation signs

Monitors placed too low, causing forward neck flexion
Chairs without lumbar support or height adjustment
Keyboards pushed too far away
Mouse positioned outside comfortable reach
Documents placed flat on desks instead of on holders
Glare from windows or overhead lights
Cluttered work surfaces that force awkward reaching
Insufficient legroom under desks
Laptops used for long periods without external peripherals

Behavioural signs

Employees rubbing their necks, shoulders, or wrists
Frequent shifting in chairs due to discomfort
Leaning forward toward screens
Hunched shoulders during typing
Stretching excessively to reach files or equipment
Avoiding certain tasks because they “hurt”

Administrative signs

Repeat complaints from the same team
Increased sick leave for musculoskeletal issues
Higher turnover in physically demanding support roles
More frequent requests for workstation changes
Reduced productivity after long peak periods, such as registration or exam cycles

A smart HR professional looks for patterns across these signs rather than waiting for a formal injury diagnosis.

3.3 Sample ergonomic risk areas in university administration

Reception and service counters

Staff at service counters may spend long periods standing or leaning forward while interacting with students. Risks include back strain, fatigue in the legs, and repetitive arm movements from document handling. Counter height, matting, and alternating sit-stand arrangements are important.

Records and archives

File retrieval can involve bending, reaching, carrying boxes, and working in cramped spaces. Hazards include manual handling injuries, dust exposure, and poor shelving stability. Regular storage audits and use of trolleys reduce risk.

Call centres and student support desks

Repeated headset use, scripted work, and continuous computer input can produce shoulder tension and neck strain. Noise, cognitive load, and emotional stress may also contribute.

Academic offices and remote work

Lecturers and researchers often work on laptops for extended periods. Without external keyboards, mice, or monitor stands, the laptop screen height is often too low, producing neck and shoulder strain.

Facilities support and logistics

Employees who move supplies, set up venues, or manage equipment face lifting, carrying, and pushing hazards. Poor route planning, heavy loads, and tight deadlines increase injury risk.

3.4 A simple hazard identification matrix

A basic matrix helps HR prioritize action.

Likelihood	Severity	Example
Low likelihood, low severity	Minor paper clutter in a quiet room	Monitor
Low likelihood, high severity	Faulty electrical wiring near wet area	Immediate action
High likelihood, low severity	Mild glare causing occasional discomfort	Short-term correction
High likelihood, high severity	Repeated unsafe lifting of heavy boxes	Urgent intervention

The matrix helps avoid two errors: overreacting to trivial issues and ignoring serious risks because they are familiar. In a university setting, even “small” ergonomic failures may become serious when repeated daily across many staff members.

3.5 Common causes and immediate controls

The table below links common ergonomic and workplace hazards to practical first responses.

Hazard	Common cause	Immediate control
Neck strain	Monitor too low	Raise monitor to eye level
Lower back pain	Poor chair support	Adjust chair, add lumbar support, review desk height
Wrist pain	Keyboard too high or too far away	Reposition keyboard, lower elbows, use wrist-neutral setup
Eye strain	Glare and poor lighting	Reorient screen, use blinds, improve lighting
Trips and falls	Loose cables and clutter	Cable management, housekeeping, clear walkways
Shoulder strain	Frequent reaching for files	Reorganise storage, bring items within easy reach
Manual handling injury	Lifting boxes alone	Use trolleys, two-person lifts, reduce load weight
Fatigue	Long uninterrupted sitting	Scheduled breaks and task variation

These controls are not exhaustive, but they are practical and immediately useful for HR managers who need to act quickly while arranging more formal assessments.

3.6 Why documentation matters

Any assessment should be documented carefully. Good documentation supports accountability and continuity. It should include:

who conducted the review
date and location
task or workstation observed
risks identified
employee concerns expressed
recommended actions
responsible person or department
target completion date
follow-up findings

This record becomes valuable if the same issue reappears, if a compensation claim arises, or if management needs evidence of due diligence. Documentation is also useful for trend analysis. If five offices report back pain in the same building, the problem may be architectural rather than individual.

4. Risk Control Measures and HR Responsibilities at UNISA

Once hazards have been identified, UNISA HR professionals must ensure that meaningful controls are introduced. The role of HR is not to replace safety officers or facilities specialists, but to coordinate people-centred action, support managers, and ensure that employees are treated fairly and consistently.

4.1 Applying the hierarchy of controls to ergonomic and workplace hazards

The hierarchy of controls is most effective when used in the correct order.

Elimination

If a hazard can be removed, that is the best solution. For example, a hazardous manual filing process might be eliminated by digitising records and reducing physical file movement.

Substitution

A less harmful alternative may be available. For instance, replacing heavy archive boxes with smaller containers can reduce lifting strain.

Engineering controls

These are physical changes to the workplace. Examples include:

adjustable chairs
height-adjustable desks
monitor arms
anti-slip flooring
better shelving design
improved lighting
trolley systems for document movement
improved ventilation

Administrative controls

These include policies and work practices such as:

job rotation
break schedules
workload balancing
safe lifting procedures
workstation assessment processes
reporting protocols
training and supervision

PPE

In ergonomic settings, PPE is limited in value. Gloves, for example, do not solve poor lifting technique or a bad workstation. PPE may still be relevant for maintenance or cleaning tasks, but it should not be mistaken for a complete ergonomic solution.

4.2 HR’s practical responsibilities

UNISA HR professionals should ensure that the following responsibilities are actively managed:

Policy development and communication
Ergonomics and hazard reporting expectations should be reflected in wellness, safety, and accommodation policies.
Induction and refresher training
New employees and managers should be introduced to workstation setup, hazard recognition, and reporting channels.
Supporting line managers
Supervisors need help identifying unsafe patterns, approving adjustments, and escalating concerns.
Facilitating referrals
Some cases require occupational health evaluation, occupational therapy input, or facility intervention.
Managing reasonable accommodation
Employees with temporary or permanent restrictions should receive timely and documented support.
Coordinating with facilities and safety structures
HR must not work in isolation. Real control requires cooperation with maintenance, procurement, health and safety representatives, and line management.
Monitoring patterns
Repeated complaints, absenteeism, or injury reports should trigger review of systemic causes.

4.3 Low-cost ergonomic interventions

Not every ergonomic fix is expensive. In many cases, low-cost changes produce substantial improvements.

Adjust chair height so feet rest comfortably on the floor or a footrest.
Place the monitor so the top of the screen is near eye level.
Keep the keyboard close to the body to avoid shoulder reaching.
Use a document holder when typing from paper.
Rearrange frequently used items within easy reach.
Improve lighting and reduce glare with blinds or screen repositioning.
Encourage regular movement and micro-breaks.
Use a laptop stand with separate keyboard and mouse for long-term laptop users.
Store heavy files between knee and shoulder height rather than on the floor or top shelves.

These interventions are particularly important in large institutions where immediate replacement of all furniture is not realistic. A thoughtful low-cost change can still prevent injuries.

4.4 Training employees and supervisors

Training should go beyond generic advice such as “sit up straight.” It should teach practical behaviours.

Employee training should cover

how to adjust chairs and screens
how to recognise early signs of strain
how to use breaks effectively
safe manual handling basics
how to report discomfort before it becomes severe
how remote workers can set up a safer workspace

Supervisor training should cover

spotting ergonomic warning signs
encouraging early reporting
understanding accommodation requests
documenting hazards and actions
avoiding blame-based responses
knowing when to refer to specialists

Training is most effective when combined with visual guides, short demonstrations, and periodic refreshers. One-off workshops tend to fade unless reinforced in day-to-day management.

4.5 Managing remote and hybrid work risks

Remote and hybrid work increase flexibility, but they also shift responsibility into home environments that UNISA does not fully control. HR professionals must recognise that remote ergonomic risk is still an occupational issue even when the work is performed off-site.

Common remote work risks include:

working from couches or beds
laptop screens placed too low
poor lighting at home
inadequate breaks because the boundary between work and rest is blurred
poor internet or software systems creating prolonged static postures during prolonged tasks
home clutter causing trip hazards around the workspace

A practical approach for remote workers includes:

a self-assessment checklist
guidance on laptop and chair setup
encouragement to create a dedicated work area where possible
scheduled online check-ins from managers
referral pathways for persistent pain or functional difficulty

4.6 Return-to-work and accommodation planning

When an employee returns after injury or illness, HR should help ensure that the return is safe and sustainable. A rushed return to full duties can cause relapse. Instead, a phased plan may be needed:

temporary reduced lifting
shorter screen-based sessions
altered seating or standing options
modified schedule
alternative duties while recovery continues

The plan must be specific, time-bound, and reviewed. The aim is not to exempt employees permanently from work, but to support recovery and maintain productivity within safe limits.

5. Legal, Ethical, and Exam-Focused Revision Framework

For UNISA HR professionals, ergonomics and hazard identification are not just operational concerns. They are also legal, ethical, and strategic responsibilities. A clear grasp of these issues helps in exams and in real workplace decision-making.

5.1 Legal and governance implications in South African workplaces

South African employers have duties to provide and maintain a working environment that is safe and without risk to health, as far as is reasonably practicable. This includes identifying hazards, assessing risks, and implementing controls. In a university environment, the obligation extends beyond obvious industrial dangers to include office ergonomics, workstation setup, housekeeping, and psychosocial pressures.

Key governance implications include:

maintaining safe systems of work
consulting employees and safety structures
keeping records of hazards, incidents, and corrective action
training and supervising employees adequately
ensuring that contractors and support services do not create unmanaged risks
responding promptly to reported concerns

HR professionals should know that failure to act on clear ergonomic warnings can create liability, reputational damage, compensation claims, and morale problems. A pattern of ignored complaints is especially risky because it suggests weak internal controls.

5.2 Ethics: dignity, inclusion, and prevention

The ethical case for ergonomics is as important as the legal case. Employees should not be expected to tolerate avoidable pain simply because the work is “office based.” Good ergonomics respects human dignity, supports inclusion, and recognizes that productivity depends on healthy bodies and minds.

Ethical management in this context means:

listening seriously to employee discomfort
avoiding dismissal of symptoms as exaggeration
balancing performance pressure with health needs
making reasonable adjustments where possible
ensuring fairness across departments and employment categories
protecting vulnerable workers, including new staff, older workers, and those with pre-existing conditions

A university that values learning should also value learning-friendly work design. Ergonomic support is part of that institutional culture.

5.3 Exam approach: how to answer ergonomics and hazard-identification questions

UNISA exam questions on this topic typically require more than definitions. Strong answers show understanding of process, application, and prioritisation. A good response usually contains three layers:

Define the concept
Explain why it matters
Apply it to a workplace scenario

For example, if asked about workplace hazard identification, an effective answer would define a hazard, distinguish it from risk, explain identification methods, and then show how an HR professional would use a checklist, employee report, and inspection to manage a specific problem.

Common exam themes

Define ergonomics and give examples in an office environment
Distinguish between hazard and risk
Explain the hierarchy of controls
Identify hazards in a workplace scenario
Describe HR’s role in employee wellness and safety
Discuss how ergonomic risk affects productivity and absenteeism
Explain how to manage workstation-related complaints
Outline steps in a hazard assessment process

What markers usually reward

Correct terminology
Logical structure
Application to a realistic workplace
Clear distinctions between similar concepts
Practical recommendations
Recognition of legal and managerial responsibilities

What weak answers usually do

give only a dictionary definition
confuse hazards with controls
list risks without explaining causes
ignore the HR role and focus only on safety officers
mention general safety ideas without ergonomic detail
fail to apply knowledge to university or office contexts

5.4 A model integrated answer structure for revision

When writing a long-answer exam response, a strong structure is:

Introduction
Briefly define the topic and its relevance to UNISA HR.
Body section one: Ergonomic risk factors
Explain posture, repetition, manual handling, lighting, and work organisation.
Body section two: Hazard identification methods
Discuss inspections, checklists, employee reports, and task analysis.
Body section three: Controls and interventions
Apply the hierarchy of controls and include practical examples.
Body section four: HR responsibilities
Show how HR coordinates training, accommodation, reporting, and monitoring.
Conclusion
Summarise why the issue matters for wellbeing, compliance, and performance.

This structure helps ensure that the answer is both complete and easy to mark.

5.5 High-yield revision points

The following points are especially useful for last-minute revision:

Ergonomics = fitting the work to the worker
Hazard = source of harm
Risk = likelihood and severity of harm
Office ergonomics includes posture, furniture, screens, lighting, and breaks
Hazard identification uses inspections, checklists, reports, and observations
The hierarchy of controls should guide intervention
HR must coordinate, document, train, and escalate
Remote work still creates ergonomic risk
Early reporting prevents chronic injury
Accommodation and safety are linked to dignity and inclusion

5.6 Consolidated study table

Topic	Key idea	UNISA HR application
Ergonomics	Fit the job to the worker	Improve workstations and task design
Hazard identification	Find sources of harm early	Use inspections, checklists, and reports
Risk assessment	Estimate likelihood and severity	Prioritise the most serious issues first
Controls	Reduce or remove the hazard	Apply hierarchy of controls
Accommodation	Adjust work for limitations	Support injured or disabled employees fairly
Training	Build awareness and skill	Teach managers and employees what to look for
Documentation	Record findings and action	Ensure accountability and trend tracking

5.7 Final synthesis for exam preparation

The most important idea is that ergonomics and hazard identification are preventive management tools, not after-the-fact responses. In a UNISA context, they support a workforce that is dispersed, diverse, and heavily reliant on digital and administrative work. HR professionals are central to this process because they connect employee experience, policy, line management, and institutional risk.

A strong exam answer should therefore show that the candidate understands:

how ergonomic hazards arise
how they are identified
how they are controlled
why HR is involved
how these measures improve wellbeing and operational performance

When these elements are linked clearly, the response demonstrates both theoretical knowledge and workplace readiness.

5.8 Quick revision checklist

Use this checklist when reviewing the topic before an exam:

Can you define ergonomics in one sentence?
Can you distinguish hazard from risk?
Can you name at least five ergonomic hazards in an office setting?
Can you explain the hierarchy of controls in order?
Can you describe at least three hazard identification methods?
Can you explain HR’s role in accommodation and reporting?
Can you apply the topic to remote work and hybrid work?
Can you write a scenario-based answer with practical examples?

If all eight questions can be answered confidently, the topic is well understood.

Ergonomics and workplace hazard identification are essential components of UNISA HR practice because they protect people before injury occurs. They also strengthen compliance, support inclusion, and improve the quality of service delivered to students and staff. For exam purposes, the key is to show not only what the concepts mean, but how they operate together in real institutional life.
