Select the best answer for each question. Pass mark: 80% (20/25).
Legislation & Regulations
Question 1
Which regulation specifically requires employers to ensure that work equipment is used only by people who have received adequate training?
Health and Safety at Work etc. Act 1974, Section 7
Provision and Use of Work Equipment Regulations 1998 (PUWER), Regulation 9
Construction (Design and Management) Regulations 2015, Regulation 13
Lifting Operations and Lifting Equipment Regulations 1998, Regulation 8
Answer: b) PUWER 1998, Regulation 9 specifically states that every employer shall ensure that all persons who use work equipment have received adequate training for the purposes of health and safety, including training in the methods to be used, risks involved, and precautions to be taken.
Question 2
Under CDM 2015, who has the duty to ensure that workers on a construction site are competent to carry out their tasks?
The client only
The Health and Safety Executive
The principal contractor
The machine manufacturer
Answer: c) Under CDM 2015, the principal contractor has a duty to plan, manage, and monitor construction work to ensure it is carried out safely. This includes ensuring that workers are suitably competent and trained for the tasks they are required to carry out.
Question 3
When does LOLER 1998 apply to a 360° excavator?
At all times during any excavation work
Only when the machine is used on a public highway
When the machine is used to lift and move loads using rated lifting accessories (e.g. chains, slings, and a lifting eye)
Only when the machine exceeds 20 tonnes operating weight
Answer: c) LOLER applies when an excavator is used as a crane to lift loads using rated lifting accessories. In this scenario, the excavator must have a current thorough examination certificate (within the last 12 months or 6 months if lifting persons), and a lift plan must be in place.
Question 4
Under HASAWA 1974, Section 7, what is the general duty of an employee at work?
To carry out risk assessments for every task
To provide PPE to fellow workers
To take reasonable care for the health and safety of themselves and others who may be affected by their acts or omissions
To inspect all equipment before each shift
Answer: c) Section 7 of the Health and Safety at Work etc. Act 1974 places a duty on every employee to take reasonable care for the health and safety of themselves and of other persons who may be affected by their acts or omissions at work, and to co-operate with their employer on health and safety matters.
Pre-use Checks
Question 5
During a pre-use walkround inspection of a 360° excavator, which of the following would be a reason to take the machine out of service immediately?
A small amount of dust on the cab windows
A cracked or damaged hydraulic hose with visible fluid weeping
The operator manual is not in the cab
The seat cushion is slightly worn
Answer: b) A cracked or damaged hydraulic hose with visible fluid leakage is a serious defect that could lead to sudden loss of hydraulic function, uncontrolled movement of the boom or dipper, and potential injury. The machine must be taken out of service, isolated, and the defect reported and repaired before further use.
Question 6
Which of the following is NOT typically checked during a pre-use inspection of a 360° excavator?
Track tension and condition
Engine oil level
Calibration of the satellite navigation system
Condition of bucket teeth and pins
Answer: c) Satellite navigation calibration is not part of a standard pre-use inspection. Key items include: tracks, undercarriage, hydraulic hoses, fluid levels, boom/dipper/bucket condition, cab integrity (ROPS/FOPS), mirrors, seatbelt, warning devices, lights, and all safety decals.
Question 7
What does ROPS stand for and why is it critical on an excavator?
Rapid Operation Protection System – it limits engine speed
Roll-Over Protective Structure – it protects the operator if the machine overturns
Remote Operating Power Supply – it enables remote control
Reverse Operation Prevention System – it stops the machine reversing into hazards
Answer: b) ROPS stands for Roll-Over Protective Structure. It is an integral part of the cab designed to protect the operator in the event the machine rolls over. It must never be modified, removed, or damaged. The operator must also always wear the seatbelt so the ROPS can function as intended.
Safe Digging Near Services
Question 8
Before excavating on any site, what is the first step in avoiding damage to underground services?
Begin trial holes with the excavator bucket
Consult up-to-date service drawings and plans for the area
Ask the site foreman if they have heard of any services
Dig only to a depth of 0.5m and check visually
Answer: b) HSG47 (Avoiding Danger from Underground Services) states that the first step is to consult up-to-date service plans and drawings before any excavation begins. This is followed by using a cable avoidance tool (CAT) and signal generator (Genny) to scan the dig area.
Question 9
What is the purpose of a CAT (Cable Avoidance Tool) and Genny (Signal Generator)?
To cut through underground cables safely
To detect and trace the approximate position of underground services before digging
To measure the depth of existing trenches
To test the water pressure in underground pipes
Answer: b) A CAT detects electromagnetic signals from underground metallic pipes and cables. The Genny applies a known signal to a specific service so the CAT can trace it more accurately. Together they help identify the approximate location (but not exact depth) of buried services before mechanical excavation begins.
Question 10
Within what distance of a known underground electricity cable should hand digging be used instead of mechanical excavation?
250mm either side of the indicated position
500mm either side of the indicated position
1 metre either side of the indicated position
2 metres either side of the indicated position
Answer: b) HSG47 recommends hand digging within 500mm either side of the indicated position of an electricity cable. Mechanical excavation should not be used within this zone. Spades (not picks or forks) should be used to reduce the risk of cable damage.
Question 11
If you strike an underground gas main while excavating, what should you do FIRST?
Continue digging to assess the extent of the damage
Attempt to repair the pipe yourself
Stop work immediately, evacuate the area, prevent ignition sources, and report the strike to your supervisor and the gas emergency number (0800 111 999)
Cover the area with soil to contain the leak
Answer: c) Striking a gas main is a serious emergency. Stop all work immediately, switch off the machine engine, evacuate personnel from the area, prevent all sources of ignition (no smoking, no vehicles starting), and report to the site supervisor and the National Gas Emergency Service on 0800 111 999.
Banksman Signals
Question 12
Which standard covers the hand signals used for directing plant and vehicles on construction sites?
BS 5228
BS 6166
BS 7671
BS 8110
Answer: b) BS 6166 covers the hand signals to be used for the directing of vehicles and plant on construction sites. Banksmen and plant operators should be trained in the same signal system to ensure clear communication.
Question 13
What should you do if you cannot clearly see the banksman’s signals while operating the excavator?
Continue with the operation using your best judgement
Sound the horn once and continue
Stop all operations immediately until clear communication is re-established
Ask a nearby worker to relay the signals
Answer: c) If you lose sight of the banksman or cannot clearly interpret their signals, you must stop all machine movements immediately. Do not resume until clear communication has been re-established. This is a fundamental safety rule for all plant operations involving banksmen.
Question 14
What is the correct banksman signal for “STOP”?
Both arms raised above the head, palms facing forward
One arm extended horizontally with palm raised
Arms crossed above the head
Clenched fist raised above the head
Answer: b) The standard STOP signal is one arm extended horizontally with the palm facing the operator (raised palm). For an EMERGENCY STOP, both arms are raised with palms facing forward and moved rapidly side to side. All operators and banksmen must know these signals.
Ground Conditions & Stability
Question 15
What is the main risk of operating a 360° excavator on soft or waterlogged ground?
Increased fuel consumption
The machine may sink, become unstable, or overturn
The engine will overheat
The tracks will wear out faster
Answer: b) Soft, waterlogged, or recently backfilled ground may not have sufficient bearing capacity to support the weight of the excavator. This can cause the machine to sink unevenly, become unstable, and potentially overturn. Always assess ground conditions before positioning the machine, and use timber mats or bog mats where necessary.
Question 16
What precaution should be taken when working near the edge of an excavation?
Position the machine as close to the edge as possible for best visibility
Keep the tracks at least one machine-width from the edge and ensure the edge is adequately supported or battered back
Only work near edges during daylight hours
Reduce engine speed to idle when near edges
Answer: b) The weight and vibration of the excavator can cause excavation edges to collapse. Keep the machine well back from the edge (typically a minimum of one track-width, though this depends on soil type and depth of excavation). Ensure edges are battered back to a safe angle or supported with trench sheets/shoring.
Question 17
What are “bog mats” used for when operating excavators?
To protect the machine paintwork from scratches
To spread the load of the machine and prevent it from sinking on soft ground
To provide a non-slip surface inside the cab
To absorb fuel spillages from the machine
Answer: b) Bog mats (heavy timber or composite mats) are placed on the ground surface to spread the weight of the excavator over a larger area, reducing ground pressure and preventing the machine from sinking into soft or waterlogged ground. They must be placed level and inspected regularly.
Slew Radius Hazards
Question 18
What is the “tail swing” of a 360° excavator?
The distance the bucket can reach forward from the machine
The arc described by the rear counterweight as the upper structure slews, which extends beyond the track width
The maximum height the boom can reach
The distance the machine can travel in reverse per minute
Answer: b) Tail swing refers to the area swept by the rear counterweight of the upper structure as the excavator slews. On most 360° excavators, the counterweight extends beyond the width of the tracks, creating a crushing hazard for anyone standing behind or beside the machine. This is one of the most common causes of fatal and serious injuries involving excavators.
Question 19
How should the slew exclusion zone around a 360° excavator be managed on a busy site?
Rely on the operator to shout warnings when slewing
Use physical barriers, warning signs, and a banksman to keep pedestrians clear of the slew radius
Paint a line on the ground around the machine
No special precautions are needed if workers are wearing high-visibility vests
Answer: b) The slew exclusion zone should be managed using a combination of physical barriers (e.g. Heras fencing, posts and chains), signage, and where necessary a dedicated banksman. This is particularly important on busy sites where pedestrians, other plant, and vehicles are operating nearby.
Loading Vehicles Safely
Question 20
When loading a dump truck with a 360° excavator, what is the safest position for the truck relative to the excavator?
Directly behind the excavator with the tailgate facing the operator
At the side of the excavator, positioned so the operator does not need to slew over the cab of the truck
Directly in front of the excavator, facing away
Position does not matter as long as the truck driver stays in the cab
Answer: b) The truck should be positioned at the side of the excavator so the operator can load the body without slewing over the truck cab. The truck driver should remain in the cab (or at a safe distance if required to leave) and never stand between the two machines. Clear communication between the excavator operator and truck driver is essential.
Question 21
What should an excavator operator check before loading material onto a vehicle on a public road?
That the vehicle is taxed and insured
That the material does not exceed the vehicle’s payload capacity and is evenly distributed across the body
That the vehicle is less than 5 years old
That the vehicle driver has an HGV licence
Answer: b) Overloading a vehicle creates risks of loss of control, structural failure, and road traffic offences. The operator should be aware of approximate load weights, ensure even distribution across the vehicle body, and avoid loading above the body sides. The driver is ultimately responsible for the load, but the operator shares a duty of care.
Emergency Procedures
Question 22
If the excavator comes into contact with an overhead power line, what should the operator do?
Jump out of the cab immediately to escape
Stay in the cab, try to drive clear if possible. If the machine cannot be moved, warn others to stay away, remain in the cab, and call for the power to be isolated
Climb onto the roof of the cab for safety
Switch off the engine and walk away normally
Answer: b) The cab and machine become energised. If you step out normally, you create a path to earth and risk electrocution. Stay in the cab and attempt to drive the machine clear. If the machine cannot be moved or catches fire, jump clear with both feet together (bunny hop away) — never touch the machine and the ground at the same time. Warn others to stay at least 10 metres away.
Question 23
What is the correct procedure if you discover a fire in the engine compartment of the excavator?
Open the engine cover fully and use water to extinguish the fire
Shut down the engine immediately, evacuate the cab, raise the alarm, and use an appropriate fire extinguisher (dry powder or CO2) from a safe position without fully opening the engine cover
Continue operating to the nearest water source
Leave the engine running so the fan helps cool the fire
Answer: b) Shut down the engine immediately (this cuts the fuel supply). Evacuate the cab safely. Raise the alarm. If safe to do so, use a dry powder or CO2 extinguisher — crack the engine cover slightly to direct the extinguisher nozzle rather than fully opening it (which would feed the fire with oxygen). Never use water on a fuel or electrical fire.
Question 24
Under RIDDOR 2013, which of the following incidents involving a 360° excavator must be reported to the HSE?
A minor scratch on the machine paintwork
A near miss that nobody witnessed
An overturning of the machine, or a collapse of an excavation caused by the machine, even if no one is injured
A flat tyre on a wheeled excavator
Answer: c) Under RIDDOR (Reporting of Injuries, Diseases and Dangerous Occurrences Regulations 2013), certain dangerous occurrences must be reported to the HSE regardless of whether anyone is injured. These include: overturning of a machine, collapse of an excavation, and contact with overhead power lines.
Question 25
When parking a 360° excavator at the end of a shift, which of the following is the correct procedure?
Leave the engine running in case the next operator needs it quickly
Park on a slope facing downhill with the bucket raised for visibility
Park on level ground, lower the bucket flat to the ground, engage the slew lock, shut down the engine, remove the key, and close all cab openings
Leave the cab door open to ventilate the machine overnight
Answer: c) Correct shut-down and parking procedure: position on firm, level ground away from traffic routes; lower the bucket flat to the ground; engage the slew lock (if fitted); allow the engine to idle for a cooling period; shut down the engine; remove the ignition key; close and lock all windows, doors, and panels; report any defects found during the shift.

Trainer Notes
Delivery Tips
Engagement
These are experienced operators — treat them as such. Use facilitated discussion rather than lecture-style delivery. Draw on their own experiences and encourage them to share incidents or near misses they’ve witnessed. The refresher should reinforce good practice and correct bad habits, not teach from scratch.
Theory Session
Use recent real-world incidents (HSE fatality reports, CPCS case studies) to illustrate key hazards — tail swing fatalities, trench collapses, and overhead power line contacts are particularly impactful
Ask candidates to describe their own daily checks and compare against the full walkround procedure — this often reveals items being skipped
Use physical banksman signal demonstrations rather than just showing images — have candidates practise signalling each other
Discuss services avoidance with reference to HSG47 — many experienced operators have never used a CAT/Genny themselves
Practical Session
Observe candidates during the pre-use check without intervening initially — note what they miss, then discuss afterwards
Set clear tasks for the practical: “Dig a trench 3m long, 600mm wide, 1.2m deep” rather than “do some digging”
Assess slew control specifically — watch for tail swing awareness, especially when pedestrians or other machines are nearby
Include a banksman exercise: have one candidate direct another who is operating
For loading exercises, insist on correct truck positioning and no slewing over the cab
If time and conditions allow, demonstrate the CAT scanner on the training area
Common 360° Excavator Incidents
The following are among the most common and most serious incident types involving 360° excavators on UK construction sites. Trainers should reference these during theory and practical sessions:
Tail swing crushing – The most common fatal incident involving excavators. Workers are crushed between the slewing counterweight and a fixed object (wall, vehicle, trench box). Emphasise exclusion zones and banksman use.
Trench collapse – Excavation sides collapse onto workers in the trench, often caused by operating too close to the edge, inadequate shoring, or surcharge loads from spoil heaps. Even shallow trenches (1.2m+) can be fatal.
Striking underground services – Hitting gas mains, electricity cables, or water mains. Gas strikes can cause explosions; electrical cable strikes can be fatal. HSG47 compliance is essential.
Overhead power line contact – The boom or dipper contacts overhead lines, often during travel with the boom raised. Fatalities occur when the operator or nearby workers create an earth path. Maintain safe clearance distances (see GS6).
Machine overturn – Caused by operating on unstable ground, working on slopes beyond the machine’s capability, or over-reaching with the boom. Always assess ground conditions and never exceed the machine’s rated capacity.
Striking pedestrians – Workers are struck by the bucket, boom, or the machine itself during travel. Site segregation and exclusion zones are critical.
Falls from the machine – Operators fall when entering or exiting the cab, often due to wet or muddy conditions. Emphasise three-point contact at all times.
Overloading vehicles – Vehicles are loaded beyond capacity, leading to loss of control on roads. Operators should be aware of approximate bucket capacities and vehicle payload limits.
Key Safety Emphasis Points
Seatbelt use is non-negotiable – The seatbelt keeps the operator within the ROPS protection envelope during an overturn. Without it, the ROPS cannot protect the operator.
Never work under a raised bucket – Even with the safety lock engaged, hydraulic failure can cause the boom to drop. Always lower the bucket to the ground before leaving the cab or carrying out maintenance.
Tail swing kills – Reinforce this message throughout the day. Operators must check behind before slewing and maintain exclusion zones.
Services: assume they’re there – Treat every dig location as potentially having underground services until proven otherwise. Plans + CAT scan + hand dig zone = safe digging.
Report defects – A culture of “just getting on with it” can lead to machines being operated with known defects. Reinforce the legal and moral obligation to report defects before operating.
Environmental awareness – Fuel and hydraulic oil spills must be contained and reported. Spill kits should be available on all machines. Noise and vibration also affect nearby residents and workers.
