Moving vehicles and plant are among the biggest causes of serious site injuries, so the priority is to keep pedestrians and vehicles apart. This is achieved by planning the site layout with separate, well-marked traffic routes, physical barriers, designated walkways and controlled crossing points. Where separation is not possible, controls such as one-way systems, speed limits and high-visibility clothing reduce the risk. Under HASAWA 1974 the employer has a general duty to provide a safe place and system of work (s.2), and workers must take reasonable care of themselves and others (s.7).
Reversing causes many fatalities. Wherever possible reversing should be avoided through drive-through layouts; otherwise a trained banksman or signaller directs the movement using agreed, recognised signals, staying in sight of the driver and out of the danger zone. Plant operators must be aware of blind spots, wear seat belts where fitted, and never carry passengers. Plant should only be operated by trained, competent and authorised people, with daily pre-use checks recorded.
Lifting operations are controlled by the Lifting Operations and Lifting Equipment Regulations (LOLER). Key principles include:
Overturning is a major risk: plant must work on firm, level ground, away from excavation edges and underground voids, with loads kept within rated capacity to avoid overloading. Poor ground conditions, soft fill or recent rain can cause a machine to tip, so ground bearing and the use of outriggers and mats must be assessed (MHSWR 1999 risk assessment by a competent person).
At the end of a shift, plant should be refuelled carefully (no naked flames, no smoking), parked on level ground with attachments lowered, the parking brake applied, and keys removed so machines are secured against unauthorised use. Any defects or near-misses are reported, and toolbox talks reinforce safe transport and lifting practice.
1. What is the single most effective way to prevent vehicles from striking pedestrians on a construction site?
The most effective control is to keep pedestrians and vehicles apart by providing separate, physically segregated routes wherever possible. Source: Workplace (Health, Safety and Welfare) Regulations 1992; HSE guidance HSG144 Workplace Transport
2. On a busy site, what is the main purpose of a pedestrian barrier alongside a vehicle route?
Barriers provide a physical separation, stopping pedestrians straying into areas where vehicles and plant are moving. Source: HSE guidance HSG144 Workplace Transport in Construction
3. You need to cross a vehicle route to reach the welfare cabin. A designated pedestrian crossing point is provided about 20 metres away. What should you do?
Designated crossing points are positioned where drivers expect pedestrians and visibility is best, so you should always use them. Source: HSE guidance HSG144 Workplace Transport; Workplace (Health, Safety and Welfare) Regulations 1992
4. A reversing dumper is approaching and you are not sure the driver has seen you. What is the safest action?
Drivers have large blind spots, especially when reversing, so you must keep well clear until you are certain it is safe. Source: HSE guidance HSG144 Workplace Transport; PUWER 1998
5. What is the main reason that vehicle routes on site should be one-way wherever it is practicable?
Reversing is a leading cause of workplace transport deaths, so one-way systems are designed to minimise the need to reverse. Source: HSE guidance HSG144 Workplace Transport in Construction
6. Why is a banksman (signaller) sometimes used when a large vehicle is reversing on site?
A trained banksman directs the reversing vehicle and keeps pedestrians clear of the blind-spot danger zone. Source: HSE guidance HSG144 Workplace Transport; PUWER 1998
7. You are acting as banksman and you lose sight of the driver in the vehicle's mirrors. What should you do?
If the driver cannot see the banksman, the vehicle must stop, because the signaller's instructions can no longer be safely received. Source: HSE guidance HSG144 Workplace Transport in Construction
8. Which feature on a site vehicle route is specifically designed to slow vehicles and protect pedestrians?
Traffic-calming features such as speed humps reduce vehicle speed, lowering the risk and severity of pedestrian collisions. Source: HSE guidance HSG144 Workplace Transport in Construction
9. You notice a section of pedestrian barrier has been knocked over, leaving a gap into the vehicle route. What should you do first?
A damaged barrier removes the protection between people and vehicles, so it should be reported and the area controlled until repaired. Source: HASAWA 1974 s.7; HSE guidance HSG144 Workplace Transport
10. Under the Workplace (Health, Safety and Welfare) Regulations 1992, traffic routes must be organised so that:
The regulations require traffic routes to be organised so that pedestrians and vehicles can circulate safely without risks to health. Source: Workplace (Health, Safety and Welfare) Regulations 1992, Regulation 17
11. A delivery lorry arrives and the only route to the unloading area crosses a pedestrian walkway with poor visibility. What is the best control to put in place?
Where segregation is not possible, a banksman controlling both the vehicle and pedestrian movement provides safe separation in time. Source: HSE guidance HSG144 Workplace Transport; Workplace (HSW) Regulations 1992
12. Plant such as a 360 excavator is slewing (rotating) near a pedestrian route. What is the safest behaviour?
The slewing body and counterweight can crush anyone within the radius, so pedestrians must keep outside the exclusion zone. Source: HSE guidance HSG144 Workplace Transport; PUWER 1998
13. Why should vehicle routes on site be kept well lit and free of obstructions?
Good lighting and clear routes improve a driver's ability to see and react to pedestrians and obstacles, reducing collisions. Source: HSE guidance HSG144 Workplace Transport in Construction
14. You are walking on site and a high-visibility waistcoat is provided. Why is wearing it important around moving plant?
High-visibility clothing makes pedestrians more conspicuous to drivers and plant operators, an important last line of defence. Source: PPE at Work Regulations 1992; HSE guidance HSG144 Workplace Transport
15. What does the abbreviation SWL stand for on a lifting accessory?
SWL stands for Safe Working Load, the maximum load the accessory is certified to lift safely. Source: Lifting Operations and Lifting Equipment Regulations (LOLER) 1998
16. You pick up a chain sling and you cannot find any marking showing its safe working load. What should you do?
Lifting accessories must be clearly marked with their SWL; unmarked equipment must not be used until checked by a competent person. Source: LOLER 1998, Regulation 7 (marking of lifting equipment)
17. Before each use, what should you do with a sling or chain you are about to use for a lift?
A pre-use visual inspection helps identify damage such as cuts, cracks or wear before the accessory is put under load. Source: LOLER 1998; PUWER 1998 (pre-use checks)
18. Under LOLER 1998, how often must lifting accessories such as slings and chains normally be thoroughly examined by a competent person?
LOLER requires lifting accessories to be thoroughly examined at least every 6 months because of the higher risk associated with their failure. Source: LOLER 1998, Regulation 9 (thorough examination)
19. Under LOLER 1998, lifting equipment used for lifting people must normally be thoroughly examined at least how often?
Equipment for lifting people must be thoroughly examined at least every 6 months because failure could cause death or serious injury. Source: LOLER 1998, Regulation 9
20. Under LOLER 1998, lifting equipment that is NOT used for lifting people must normally be thoroughly examined at least how often?
Lifting equipment not used to lift people generally requires thorough examination at least every 12 months under LOLER. Source: LOLER 1998, Regulation 9
21. While slinging a load you notice the chain sling has a link that is stretched and slightly bent. What should you do?
A stretched or distorted link indicates the sling has been overloaded or damaged and must be withdrawn from use immediately. Source: LOLER 1998; HSE guidance on lifting accessories
22. A crane is lifting a load near your work area. Where should you position yourself?
You must never stand or work under a suspended load, as a failure or slip of the load could cause fatal injuries. Source: LOLER 1998; HSE guidance on safe use of cranes
23. A load to be lifted is heavier than the marked safe working load of the available sling. What is the correct action?
Never exceed the marked safe working load; an accessory rated for the load weight must be used to lift it safely. Source: LOLER 1998, Regulation 4 (strength and stability)
24. Under LOLER 1998, who must plan a lifting operation involving a crane?
LOLER requires lifting operations to be properly planned by a competent person, typically an appointed person for crane lifts. Source: LOLER 1998, Regulation 8 (organisation of lifting operations)
25. Wind speeds are rising and the crane manufacturer's limit is being approached during a lift. What is the correct decision?
Lifting in wind above the safe limit risks loss of control of the load and crane instability, so the lift must be stopped. Source: LOLER 1998; HSE guidance on safe use of cranes (BS 7121)
26. What is the purpose of a tag line (hand line) attached to a load being lifted by a crane?
A tag line lets an operative guide and steady the load while keeping a safe distance and avoiding standing underneath it. Source: LOLER 1998; HSE guidance on safe use of cranes
27. When a thorough examination of lifting equipment reveals a defect that could cause danger, what must the competent person do?
Under LOLER the competent person must report defects to the dutyholder, and a defect of imminent danger must also be reported to the enforcing authority. Source: LOLER 1998, Regulation 10 (reports and defects)
28. What is the main role of a banksman (signaller) on a construction site?
A banksman is a trained signaller whose job is to guide drivers and protect people during vehicle movements, particularly reversing where the driver's vision is limited. Source: HSE guidance HSG144 (The safe use of vehicles on construction sites)
29. Why is reversing vehicles considered one of the most dangerous activities involving site transport?
Most people killed or injured by site vehicles are struck during reversing because the driver cannot see directly behind, which is why reversing should be avoided or strictly controlled. Source: HSE guidance HSG144 (The safe use of vehicles on construction sites)
30. You are acting as banksman and you lose sight of the driver while guiding a reversing lorry. What should you do?
If the banksman and driver lose sight of each other the agreed rule is to stop the vehicle at once, because the signaller can no longer safely control the movement. Source: HSE guidance HSG144 (The safe use of vehicles on construction sites)
31. A driver is reversing and can no longer see the banksman in the mirrors. What must the driver do?
The driver must stop immediately whenever they lose sight of the signaller, as continuing without a clear signal could lead to striking a person or object. Source: HSE guidance HSG144 (The safe use of vehicles on construction sites)
32. Where should a banksman stand when directing a reversing vehicle?
The banksman must stay in a safe, clearly visible position out of the vehicle's path while keeping a full view of the area being reversed into. Source: HSE guidance HSG144 (The safe use of vehicles on construction sites)
33. What colour of high-visibility clothing arrangement helps a banksman be most easily distinguished from other workers on a busy site?
Giving the banksman distinctive high-visibility clothing helps the driver identify the one person authorised to give signals among everyone else on site. Source: HSE guidance HSG144 (The safe use of vehicles on construction sites)
34. The best way to reduce the risk from reversing vehicles on site is to:
The first control in the hierarchy is to remove the need to reverse using site layout measures such as one-way systems and turning areas, before relying on banksmen or alarms. Source: HSE guidance HSG144 (The safe use of vehicles on construction sites)
35. You have not been trained as a banksman, but a lorry driver asks you to guide him back because no one else is around. What should you do?
Only trained and authorised signallers should act as banksmen; an untrained person directing a reversing vehicle puts themselves and others at serious risk. Source: HSE guidance HSG144 (The safe use of vehicles on construction sites)
