360 Above 10Tonne CPCS Test Questions (Plant
Operations Level 2) with complete Solutions
SECTION I: CORE COMPULSORY QUESTIONS
These questions appear on every CPCS A59 theory test paper.
Question 1
If setting up to work in a pedestrianised area, state THREE factors that need to be
taken into account.
Correct Answer:
1. Segregation of pedestrians – Establish clear pedestrian access routes and
segregate them from the work area using barriers or cones .
2. Exclusion zones and warning signage – Set up appropriate exclusion zones
around the machine with visible warning signs to protect the public .
3. Banksman/Signaller – Ensure a banksman/signaller is used for guiding
manoeuvres where visibility is restricted .
Rationale: In pedestrianised areas, public safety is the highest priority. Pedestrians
must be kept separate from the machine's operating radius. Exclusion zones
prevent unauthorised entry, and a signaller ensures the operator has guidance
when visibility is poor .
Question 2
The operator is asked to excavate a new trench. State FIVE different requirements
that must be considered or implemented before work commences.
,Correct Answer:
1. Utility/Cable Location – Identify and locate all buried services (gas, water,
electricity, telecoms) using cable avoidance tools (CAT) and utility plans .
2. Ground Conditions Assessment – Assess the soil type to determine trench
shoring and support requirements .
3. Permits and Documentation – Check for relevant work permits, method
statements, and risk assessments .
4. Exclusion Zone – Establish a safe working zone and ensure all personnel are
clear of the danger area .
5. Spoil Placement Plan – Plan where excavated material will be placed;
ensure it is set back at least 1 metre from the trench edge to prevent
collapse .
Rationale: Proper pre-work planning prevents accidents and ensures compliance
with health and safety legislation. Identifying services prevents strike hazards,
ground assessment prevents collapse, and having plans and permits ensures legal
compliance .
Question 3
Explain ALL visual checks that must be carried out on all types of quick-hitch
bucket attaching systems before use.
Correct Answer:
1. Locking System Engagement – Check the locking mechanism is fully
engaged and in the correct position .
2. Pins and Retaining Devices – Verify all pins are in place, fully inserted, and
securely retained .
3. Structural Damage/Wear – Inspect for any visible cracks, deformation, or
excessive wear on the coupler body .
, 4. Indicator Pins – If fitted, check any indicator pins or visual engagement
indicators are showing correct engagement (e.g., pin fully visible) .
5. Hydraulic Connections – Check any hydraulic hoses or connections for leaks
or damage (if hydraulic quick-hitch fitted) .
Rationale: A failed quick-hitch system can cause the bucket to detach during
operation, posing a catastrophic safety risk. Visual checks ensure the system is
physically secure and has not suffered wear that could lead to failure. The
operator must physically confirm engagement before any work commences .
Question 4
What factors determine the shoring requirements of a trench?
Correct Answer:
1. The type/condition of ground – Rock, clay, sand, waterlogged, or previously
disturbed ground all require different shoring .
2. The depth of the trench – Deeper trenches exert more pressure on the
walls and require more substantial support .
3. Groundwater presence – The presence of water can destabilise trench walls
and increase shoring requirements .
4. Nearby traffic or structures – Vibrations from nearby roads or buildings can
affect trench stability .
5. Duration of the excavation – Trenches left open for longer periods may
require additional support .
Rationale: Deeper trenches and less stable ground (like sand) exert more pressure
on the trench walls and require more substantial shoring. The CPCS theory
references the HSE guidance on excavation safety, which mandates that shoring
must be designed based on these factors .
, Question 5
Describe TWO actions to be taken for an open trench at the end of a working day.
Correct Answer:
1. Secure the trench – Erect barriers, guardrails, or warning signs around the
trench to prevent falls .
2. Cover or backfill – Cover the trench with heavy-duty boards or backfill it if
possible to prevent access and protect it from weather .
Rationale: Open trenches left unattended are a significant fall hazard. Physically
securing them with barriers or backfilling them protects workers and the public
when the site is unattended .
Question 6
Why must excavator operators not begin to load vehicles until the forward-tipping
dumper driver is clear of their machine?
Correct Answer:
To avoid striking the dumper driver with the bucket, attachment, or falling
material.
Rationale: The driver needs to be in a safe location, visible to the operator, to avoid
being crushed or hit by the swinging excavator bucket or falling material. The
driver should only approach the vehicle when the excavator bucket is static and
the operator has acknowledged them .
Question 7
Name TWO types of equipment used to ensure that excavation levels,
measurements and positions are to the required specification.
Correct Answer:
