NEBOSH Exam Questions & Answers 2026 (21–30)

✓ Correct answer: A. Respiratory illness

Airborne dust generated during construction can be inhaled and cause respiratory illness in workers and bystanders. Why the other options are incorrect: • Better posture: Posture problems are not caused by exposure to construction dust. • Higher staff morale: Staff morale is not a health hazard resulting from dust inhalation. • Lower noise levels: Site noise is a separate issue and is not linked to the dust hazard. • Improved material storage: Storage conditions for materials are not affected by dust generated during construction.

✓ Correct answer: A. Dedicated canteen or rest areas that are clean

Employers are required to provide clean canteens or designated rest areas so that employees can eat without exposure to hazardous substances. Why the other options are incorrect: • Respiratory protection equipment: Respiratory protection guards against inhaling hazards but does not create a facility for safe eating. • Sound level monitoring: Measuring noise levels addresses hearing risk, not safe eating arrangements. • Safety railings: Safety railings are fall prevention measures and have no relevance to eating facilities. • Access ladders: Ladders are access tools with no connection to workplace welfare eating facilities.

✓ Correct answer: A. Dedicated pedestrian lanes

Dedicated pedestrian lanes protect people by physically dividing them from vehicle traffic. Why the other options are incorrect: • Additional warning signs: Warning signs can alert people to hazards but do not create a physical barrier between pedestrians and vehicles. • Informal dress code: What someone wears has no bearing on preventing vehicle-pedestrian accidents. • Regular team briefings: Team briefings enhance information sharing but do not directly protect pedestrians from vehicles. • Employee performance reviews: Performance reviews evaluate staff work quality rather than addressing movement-related risks.

✓ Correct answer: A. Training for platform operators

Thorough training for those who operate mobile elevating work platforms ensures they are used correctly and safely. Why the other options are incorrect: • Additional on-site signs: Additional signage can highlight hazards but does not guarantee safe operation of the platform. • Informal dress for workers: What an operator wears has no impact on the safe operation of an elevating platform. • Internal staff communications: Internal communications keep staff informed but do not reduce the risks of using elevating platforms. • Additional paid leave as a bonus: Reward schemes may motivate staff but have no effect on the safe use of mobile elevating platforms.

✓ Correct answer: A. Arguments over ticket prices or payments

Disagreements about fares or payment frequently trigger aggressive responses from members of the public, putting transport workers at heightened risk of violence. Why the other options are incorrect: • Being required to wear a uniform: Wearing a uniform helps the public identify transport workers but does not in itself make them more vulnerable to aggression. • Adhering to scheduled service times: Following service schedules organises working patterns but is not a source of violence risk. • Maintaining safe driving standards: Safe driving practices reduce the risk of road incidents but have no bearing on aggressive behaviour from passengers. • Filling in required administrative forms: Completing administrative forms is part of the job but does not contribute to the risk of encountering violence.

✓ Correct answer: A. Disorientation and collisions

Insufficient signage in walkways leads to disorientation and increases the chance of collisions. Why the other options are incorrect: • Better air circulation: Air circulation relates to environmental conditions, not walkway navigation. • Greater work output: Work output is an organisational outcome, not the immediate hazard from poor signage. • Stronger team collaboration: Team collaboration is not affected by whether walkways are properly signed. • Improved staff spirit: While poor conditions may lower morale, the direct hazard is collision.

✓ Correct answer: A. Ensuring the indoor temperature is kept at a comfortable level

Employers are legally required to maintain indoor workplace temperatures at a reasonable level to protect the comfort and welfare of their workforce. Why the other options are incorrect: • Supplying respiratory protective equipment: Respiratory equipment controls exposure to airborne substances, not thermal conditions. • Fitting automatic fire suppression systems: Sprinkler systems are designed to suppress fires and have no bearing on workplace temperature. • Equipping workers with fall-arrest harnesses: Fall-arrest harnesses protect against falls from height and are unrelated to temperature management. • Organising fire evacuation practice sessions: Fire evacuation drills rehearse emergency procedures and do not influence indoor temperature.

✓ Correct answer: A. Protective covers or physical barriers

Physical covers or barriers placed over fragile roof lights stop workers from falling through them. Why the other options are incorrect: • Staff bonus payments: Bonus payments are a financial incentive and provide no physical barrier against falling through a roof light. • Workplace social events: Social events raise team spirit but offer no structural safeguard against skylight falls. • Informational display boards: Display boards can convey warnings but cannot physically prevent a worker from falling through a fragile roof. • Adjustable working schedules: Altering shift patterns has no effect on the physical danger posed by brittle roof lights.

✓ Correct answer: A. Camera monitoring systems

Camera monitoring discourages aggressive conduct and captures footage that can be used as evidence following any incident. Why the other options are incorrect: • Yearly financial incentives: Financial rewards can drive productivity but play no role in preventing aggressive behaviour. • Adjustable shift schedules: Adjustable schedules benefit staff wellbeing but offer no protection against violent incidents. • Complimentary staff parking: Complimentary parking reduces commuting costs but has no effect on aggression at work. • Informal clothing guidelines: Informal clothing policies shape workplace culture but do nothing to reduce the likelihood of violence.

✓ Correct answer: A. Fitness for work assessments

Fitness for work assessments establish whether employees are in a suitable condition to work safely and are not impaired by substances. Why the other options are incorrect: • Holding weekly team social events: Team social events help build relationships and morale but are not a mechanism for checking whether staff are impaired. • Developing a corporate brand identity: Developing a brand identity supports organisational image but does not assess staff fitness or substance use. • Introducing a casual dress code: A casual dress code affects what employees wear to work and has no role in identifying impairment. • Redesigning the office floor plan: Changing the layout of office space affects the working environment but is not relevant to detecting substance-related impairment.
