CWLP Material Handling 3 — Questions and Answers
Question 1: An automated storage and retrieval system (AS/RS) is BEST justified when a warehouse has:
- Wide product variety with low daily volume
- High-volume, high-density storage needs with limited floor space (Correct answer)
- Seasonal peaks requiring flexible staffing
- Products that require manual inspection before storage
Correct answer: High-volume, high-density storage needs with limited floor space
AS/RS systems are ideal for high-density, high-throughput environments where floor space is at a premium and consistent throughput is needed.
Question 2: What is 'slotting' in a warehouse context?
- Assigning specific locations to SKUs based on velocity, weight, and size to optimize picking efficiency (Correct answer)
- Cutting slots in shelving for label holders
- Scheduling time slots for inbound trucks
- Sorting parcels into delivery route groups
Correct answer: Assigning specific locations to SKUs based on velocity, weight, and size to optimize picking efficiency
Slotting strategically assigns storage locations to products based on pick frequency, weight, and size to minimize travel time and ergonomic risk.
Question 3: A reach truck differs from a counterbalanced forklift primarily because it:
- Uses diesel fuel instead of electric power
- Can extend its forks forward without moving the entire truck (Correct answer)
- Operates on outdoor terrain and dock areas
- Has a higher maximum lift height for outdoor stacking
Correct answer: Can extend its forks forward without moving the entire truck
A reach truck has a pantograph mechanism that extends the forks (and sometimes the mast) forward into the rack while the truck body remains in the aisle.
Question 4: When stacking pallets in a block stack configuration, the PRIMARY stability concern is:
- The color coding on the top pallet
- Column stacking alignment and maximum stack height per product type (Correct answer)
- The temperature of the storage area
- Whether the pallets are wood or plastic
Correct answer: Column stacking alignment and maximum stack height per product type
Column stacking places weight directly over the pallet corners (strongest points), and observing maximum stack height prevents collapse from top-heavy loads.
Question 5: Which type of conveyor is MOST appropriate for transporting irregularly shaped or fragile products that cannot be placed on rollers?
- Roller conveyor
- Belt conveyor (Correct answer)
- Gravity skatewheel conveyor
- Chain conveyor
Correct answer: Belt conveyor
Belt conveyors provide a flat, continuous surface that supports irregularly shaped or fragile items that could tip or fall through roller or skatewheel systems.
Question 6: In a warehouse where FIFO (First-In, First-Out) rotation is critical, which racking system is MOST appropriate?
- Drive-in rack
- Pushback rack
- Carton flow (gravity flow) rack (Correct answer)
- Cantilever rack
Correct answer: Carton flow (gravity flow) rack
Carton flow racks are loaded from the back and picked from the front, automatically ensuring FIFO rotation without operator intervention.
Question 7: What is the primary reason for performing a daily pre-operation inspection on powered industrial trucks?
- To satisfy insurance documentation requirements
- To identify defects before use that could endanger the operator or other workers (Correct answer)
- To calculate fuel or battery consumption rates
- To record operating hours for preventive maintenance scheduling only
Correct answer: To identify defects before use that could endanger the operator or other workers
OSHA 29 CFR 1910.178(q) requires daily inspections to identify and correct defects before operation, preventing accidents caused by faulty equipment.
