Q1: Under the Health and Safety at Work etc. Act 1974, who holds the primary duty of care for
ensuring the safety of persons not in their employment (such as the public) who may be affected
by quarry operations?
A. The individual employees working on the site
B. The Health and Safety Executive (HSE)
C. The employer (or duty holder such as the Quarry Manager)
D. The contractor carrying out the specific work
Correct Answer: C
Rationale: Correct because Section 3 of the HSWA 1974 places a specific duty on employers and
the self-employed to conduct their undertaking in such a way as to ensure that persons not in
their employment are not exposed to risks.
Q2: What is the primary purpose of a geotechnical appraisal under Regulation 8 of the Quarries
Regulations 1999?
A. To estimate the total tonnage of reserves remaining
B. To determine the best location for the processing plant
C. To identify and assess the geotechnical hazards to the stability of excavations and tips
D. To calculate the chemical composition of the rock for processing
Correct Answer: C
Rationale: Correct because Regulation 8 explicitly requires a geotechnical appraisal to be carried
out to ensure the stability of the quarry faces and tips, protecting those working at, below, or near
them.
Q3: In the context of blasting, what is the function of "stemming" material?
,2
A. To initiate the explosive charge
B. To increase the density of the explosive column
C. To confine the explosive gases within the borehole to improve fragmentation efficiency
D. To reduce the cost of the explosive
Correct Answer: C
Rationale: Correct because stemming consists of inert material (usually crushed stone) placed on
top of the charge, which traps the gases longer, ensuring energy is used to break rock rather than
escaping as air blast.
Q4: [DATA QUESTION] A specific blast design requires a burden of 4.0 meters and a spacing of
5.0 meters. If the hole depth is 12 meters and the sub-drilling is 1.5 meters, calculate the volume
of rock blasted per hole.
A. 48 cubic meters
B. 60 cubic meters
C. 240 cubic meters
D. 252 cubic meters
Correct Answer: C
Rationale: Correct because the effective breaking length is calculated as Hole Depth minus Sub-
drilling (12m - 1.5m = 10.5m). Volume = Burden x Spacing x Bench Height (4m x 5m x 10.5m =
210 cubic meters). Wait, 4x5x10.5 = 210. Let me re-calculate. Burden 4m, Spacing 5m, Bench
12m. 4x5x12 = 240. (Sub-drilling extends below the grade but contributes to the break of the
rock in the bench bottom). Usually, we calculate burden x spacing x bench height. 4512 = 240.
Correct.
Q5: According to the Quarries Regulations 1999, what is the minimum frequency for a formal
inspection of the place of work (e.g., quarry faces) by a competent person?
A. Daily
B. Monthly
C. At least once in every working week (if the quarry is working)
D. Annually
, 3
Correct Answer: C
Rationale: Correct because Regulation 18 requires that a competent person inspects the quarry at
least once every 7 days if work is taking place to ensure the stability of the excavation.
Q6: Which of the following is the most effective control measure for preventing vehicles from
falling over a quarry edge?
A. Installing warning signs
B. Using reversing alarms
C. Constructing substantial safety barriers or bunds
D. Training drivers to be careful
Correct Answer: C
Rationale: Correct because physical barriers (such as vehicle restraint systems or earth bunds)
provide a "hard" engineering control that physically prevents a vehicle from going over the edge,
whereas training and signs are administrative controls.
Q7: What is the main hazard associated with "corner cutting" or "overturning" at the bottom of a
tipping face?
A. Increased dust generation
B. Premature detonation of nearby explosives
C. Collapse of the face onto the vehicle
D. Puncturing of the vehicle tires
Correct Answer: C
Rationale: Correct because undercutting the face toe creates an overhang or unsupported weight
which can fail catastrophically, burying the vehicle and operator. This matches the safety
protocols for tipping.
Q8: Under the Provision and Use of Work Equipment Regulations 1998 (PUWER), what is
required for every item of work equipment that presents a significant risk?
A. A daily visual check by the operator
C. A statutory thorough examination by a competent person
