INTRODUCTION
The Mississippi Conveyor System Contractor examination assesses the knowledge and skills required to
construct, install, maintain, and repair mechanical handling equipment within the state. The exam
evaluates competency across conveyor fundamentals, component selection, safety compliance, electrical
controls, and structural integrity. Questions are presented in multiple-choice and scenario-based formats
to test real-world application and professional decision-making. Candidates must demonstrate
understanding of industry standards including ASME B20.1, OSHA regulations, and manufacturer
specifications. The examination emphasizes practical judgment, hazard recognition, and ethical
contractor practices. Success requires both theoretical knowledge and the ability to apply concepts to
workplace situations encountered in conveyor system operations.
SECTION ONE – QUESTIONS 1–100
Question 1
What is the primary function of a conveyor system in material handling operations?
A. Store materials temporarily
B. Transport materials from one location to another
C. Process raw materials into finished goods
D. Package finished products for shipment
🟢 Correct answer: B
🔴 Explanation: The fundamental purpose of a conveyor system is to move materials efficiently
between points within a facility, reducing manual labor and improving productivity. Storage,
processing, and packaging are separate functions.
Question 2
Which conveyor type uses a continuous loop of material supported by rollers or a slider bed?
A. Screw conveyor
B. Belt conveyor
C. Bucket elevator
D. Pneumatic conveyor
,🟢 Correct answer: B
🔴 Explanation: A belt conveyor uses a continuous belt loop supported by rollers or a slider bed to
carry bulk or unit loads. Screw conveyors use a rotating auger, bucket elevators use buckets on a
chain, and pneumatic conveyors use air pressure.
Question 3
The purpose of a nip-point guard on a conveyor system is to:
A. Protect the belt from wear
B. Protect workers from hazards where rotating parts could pinch clothing or limbs
C. Prevent material from falling off the belt
D. Reduce noise from the drive motor
🟢 Correct answer: B
🔴 Explanation: Nip-point guards are required at locations where rotating shafts, rollers, or pulleys
could pinch clothing or limbs. They protect personnel from entanglement and crushing injuries.
Question 4
What is the primary advantage of a screw conveyor?
A. It can transport materials vertically
B. It can handle a wide range of materials and is dust-tight
C. It is the fastest conveyor type
D. It requires very little maintenance
🟢 Correct answer: B
🔴 Explanation: Screw conveyors can handle a wide range of materials and their enclosed design
makes them dust-tight, which is advantageous for containing fine or hazardous materials.
Question 5
The purpose of a zero-speed switch on a conveyor drive is to:
A. Detect the exact moment the belt reaches maximum speed
B. Shut down the motor if the belt stops unexpectedly, preventing fire or damage
C. Activate the emergency stop button automatically
D. Measure belt tension in real time
🟢 Correct answer: B
🔴 Explanation: Zero-speed switches monitor belt motion; if the belt stops while the motor continues
running, the switch trips to prevent material buildup, fire risk, and equipment damage.
Question 6
Which classification best distinguishes a conveyor that moves palletized boxes from one point to
another?
A. Bulk handling
B. Unit handling
C. Continuous flow
D. Batch processing
🟢 Correct answer: B
🔴 Explanation: Unit handling conveyors are designed for discrete items such as pallets, cartons, or
,packages. Bulk handling moves loose materials like grain or coal.
Question 7
What is the maximum safe incline angle for a dry, free-flowing sand conveyor primarily determined
by?
A. Belt tensile strength
B. Motor horsepower
C. Angle of repose of the material
D. Idler spacing
🟢 Correct answer: C
🔴 Explanation: The angle of repose of the material determines the maximum incline at which material
will remain on the belt without sliding back. Other factors affect capacity but not the fundamental
angle limit.
Question 8
Which of the following is NOT a basic component of a belt conveyor system?
A. Belt
B. Drive pulley
C. Idler pulley
D. Hydraulic cylinder
🟢 Correct answer: D
🔴 Explanation: Basic belt conveyor components include the belt, drive pulley, idler pulley, take-up
device, and supporting structure. Hydraulic cylinders are not standard components of belt conveyors.
Question 9
A conveyor system is being designed for a food processing facility. The belt must withstand frequent
washdowns with caustic cleaning agents and operate at temperatures up to 180°F. Which belt material
is most appropriate?
A. Nylon-reinforced rubber belt
B. Polyester fabric belt with PVC cover
C. Stainless steel mesh belt
D. Polyurethane belt with cotton reinforcement
🟢 Correct answer: C
🔴 Explanation: Stainless steel mesh belts resist caustic chemicals and high temperatures, making
them ideal for food processing washdown environments. Rubber and PVC degrade with caustics and
high heat.
Question 10
In a belt splicing operation, a mechanical fastener splice is distinguished by:
A. Its ability to be welded on-site
B. A mechanical clamping system that secures the splice without heat
C. The use of epoxy resin for bonding
D. A vulcanizing press requirement
, 🟢 Correct answer: B
🔴 Explanation: Mechanical fasteners mechanically clamp belt ends together, offering a quick, non-
heat splice solution. Vulcanized splices use heat and pressure.
Question 11
According to ASME B20.1, a "qualified person" for conveyor maintenance is defined as:
A. Any employee who has worked with conveyors for more than one year
B. A person who, by possession of a recognized degree or certificate, or who by extensive knowledge
and experience, has successfully demonstrated the ability to solve problems relating to the subject
matter
C. A supervisor who has completed the company's general safety orientation
D. Any licensed contractor
🟢 Correct answer: B
🔴 Explanation: ASME B20.1 defines a qualified person as one who by degree, certificate, or extensive
knowledge and experience has demonstrated the ability to solve conveyor-related problems. Time
alone does not qualify a person.
Question 12
When performing Lockout/Tagout on a conveyor motor, which of the following steps is NOT required?
A. De-energize the motor and verify zero voltage
B. Apply a lock to the circuit breaker handle
C. Remove the belt for inspection before locking out
D. Attach a tag indicating the reason for lockout
🟢 Correct answer: C
🔴 Explanation: Removing the belt is unnecessary for LOTO; the focus is on isolating energy sources,
not mechanical disassembly. Lockout must be applied before any work begins.
Question 13
Photoelectric sensors are most commonly used in conveyor systems for:
A. Measuring belt speed
B. Detecting the presence of material for divert or accumulation control
C. Monitoring motor temperature
D. Controlling variable frequency drives
🟢 Correct answer: B
🔴 Explanation: Photoelectric sensors emit a light beam and detect interruptions, making them ideal
for object detection and jam sensing in accumulation and divert applications.
Question 14
A conveyor's take-up device is primarily responsible for:
A. Adjusting belt speed automatically
B. Maintaining proper belt tension to compensate for stretch and load variations
C. Detecting material on the belt
D. Providing power to the drive motor
