NEBOSH Manual Handling and Construction Safety 1 — Questions and Answers
Question 1: What factors are assessed in a manual handling risk assessment using the TILEO framework?
- Task (actions involved), Individual (worker capability, health), Load (weight, size, stability, temperature), Environment (space, floor, temperature), Other (PPE, training) (Correct answer)
- Time, Intensity, Location, Equipment, Operations
- Total, Injuries, Limits, Exposure, Operations
- Temperature, Impact, Load, Ergonomics, Overexertion
Correct answer: Task (actions involved), Individual (worker capability, health), Load (weight, size, stability, temperature), Environment (space, floor, temperature), Other (PPE, training)
The TILEO framework systematically assesses manual handling risks: Task (twisting, repetitive, reach), Individual (pregnant, young, medical conditions, training), Load (heavy, bulky, sharp, hot, unpredictable), Environment (confined, wet floor, temperature extremes, stairs, lighting), Other factors (PPE restricting movement, training adequacy). All five must be assessed for any significant manual handling task.
Question 2: What is the correct manual handling technique for lifting a heavy box from floor level?
- Plan the lift, close to the body, feet shoulder-width apart, bend knees (not back), straight back, smooth controlled movement, avoid twisting — turn feet not back (Correct answer)
- Bend at the waist with straight legs
- Twist the back to place the load to the side
- Always lift with one hand to keep the other free
Correct answer: Plan the lift, close to the body, feet shoulder-width apart, bend knees (not back), straight back, smooth controlled movement, avoid twisting — turn feet not back
Safe manual handling: 1) Assess the load and plan, 2) Position feet shoulder-width apart beside the load, 3) Bend at the knees (not the waist), 4) Maintain natural spinal curves (don't flex the lumbar spine), 5) Grip firmly, 6) Lift by straightening legs with load close to the body, 7) Move feet to change direction — don't twist the spine.
Question 3: What is 'team lifting' and when is it required?
- Coordinated lifting by two or more workers when a load is too heavy or awkward for safe solo lifting — requires a designated leader, synchronized movement, and all participants of sufficient height/strength (Correct answer)
- Team lifting is only required for loads over 50 kg
- Team lifting is always safer than using mechanical aids
- Any two workers can team lift without prior coordination
Correct answer: Coordinated lifting by two or more workers when a load is too heavy or awkward for safe solo lifting — requires a designated leader, synchronized movement, and all participants of sufficient height/strength
Team lifting is used when loads exceed individual capacity or handling solo creates excessive postural stress. Requirements: designate one person to direct, agree a plan before lifting, matched height and capability of all participants, synchronized initiation and movement, and adequate space for all handlers. Team lifting has limitations — communication failure and mismatched heights create risks.
Question 4: What are the main causes of fatal accidents in Gulf construction?
- Falls from height, struck by vehicle or plant, collapse of excavations or structures, electrical contact, and crane/lifting equipment failures — accounting for the majority of construction fatalities (Correct answer)
- Only falls from height cause fatalities
- Construction fatalities are primarily from chemical exposure
- Falls from height account for all construction deaths
Correct answer: Falls from height, struck by vehicle or plant, collapse of excavations or structures, electrical contact, and crane/lifting equipment failures — accounting for the majority of construction fatalities
Gulf construction fatal accident causes (consistent with ILO and regional data): falls from height (scaffolding, roof edges, fragile surfaces, openings), struck by plant (mobile cranes, excavators, delivery vehicles), excavation collapse, electrical contact (overhead lines, temporary wiring), and lifting equipment failure. These are the 'Fatal Four' with the addition of crane incidents.
Question 5: What is required before work begins below overhead power lines on a Gulf construction site?
- Identify line voltage, establish statutory minimum clearance distances, use goal posts or barriers to prevent over-height plant access, consider diversion or de-energization, and brief all site personnel (Correct answer)
- Overhead power lines can be touched if work is brief
- Standard safety boots protect against overhead line contact
- Only cranes need to maintain clearance from overhead lines
Correct answer: Identify line voltage, establish statutory minimum clearance distances, use goal posts or barriers to prevent over-height plant access, consider diversion or de-energization, and brief all site personnel
Overhead power line contact is an immediate electrocution hazard for construction plant operators. Requirements: survey and mark all OHPLs, establish safe clearance distances (for 33kV: 3m minimum, for 11kV: 2m, for 400kV: greater distances — contact utility for specific voltage data), erect goal posts (height restrictors) on approach routes, consider requesting line diversion or temporary de-energization for work directly beneath.
Question 6: What is 'CDM' (Construction Design and Management) regulation and how does it apply in the Gulf context?
- CDM places duties on clients, designers, and contractors to consider H&S at every stage of a project — from design through construction to maintenance. Gulf countries have equivalent project safety regulations requiring pre-construction safety planning. (Correct answer)
- CDM only applies to projects in the UK
- CDM regulates financial management of construction projects
- CDM only applies during the construction phase — not design
Correct answer: CDM places duties on clients, designers, and contractors to consider H&S at every stage of a project — from design through construction to maintenance. Gulf countries have equivalent project safety regulations requiring pre-construction safety planning.
UK CDM 2015 requires: clients to appoint competent principal designers and contractors, designers to eliminate hazards through design, principal contractors to produce a Construction Phase Plan, and all parties to cooperate. Gulf equivalents (Qatar ASHGHAL, Dubai CDA, Abu Dhabi CDA H&S requirements, Saudi MOL regulations) impose analogous duties at project planning, design, construction, and handover stages.
