MHC Storage & Inventory Management 3 â Questions and Answers
Question 1: What does 'cross-docking' eliminate in the warehousing process?
- The need for transportation between facilities
- Long-term storage of goods in the warehouse (Correct answer)
- The requirement for barcode scanning on inbound shipments
- Quality inspection of incoming products
Correct answer: Long-term storage of goods in the warehouse
Cross-docking transfers goods directly from inbound to outbound transportation with little or no storage time, reducing warehousing costs.
Question 2: Under OSHA standards, what is the maximum allowable height for stacking pallets in a warehouse without additional securing measures?
- It is determined by the product weight and rack rating, not a fixed height (Correct answer)
- 6 feet
- 8 feet
- 12 feet
Correct answer: It is determined by the product weight and rack rating, not a fixed height
OSHA does not set a universal fixed height limit; stack height must be determined by the structural limits of the rack, pallet, and product specifications.
Question 3: What inventory metric does the formula (COGS Ă· Average Inventory) calculate?
- Inventory carrying cost
- Inventory turnover ratio (Correct answer)
- Days sales of inventory
- Gross margin return on inventory
Correct answer: Inventory turnover ratio
Dividing Cost of Goods Sold by Average Inventory gives the inventory turnover ratio, showing how many times stock is sold and replaced in a period.
Question 4: Which hazardous material storage rule requires incompatible chemicals to be physically separated?
- Segregation requirement (Correct answer)
- Containment hierarchy rule
- Co-storage exemption
- Compatible grouping standard
Correct answer: Segregation requirement
Segregation requirements mandate that incompatible hazardous materials be stored separately to prevent dangerous reactions in case of a spill or leak.
Question 5: A warehouse manager notices cycle counts consistently differ from the WMS record. What is the FIRST corrective step?
- Immediately write off all discrepancies
- Investigate root causes such as process errors or unauthorized access (Correct answer)
- Switch from cycle counting to annual physical inventory
- Increase reorder points across all SKUs
Correct answer: Investigate root causes such as process errors or unauthorized access
Before making inventory adjustments, the root cause of discrepanciesâsuch as receiving errors, pick errors, or theftâmust be identified and corrected.
Question 6: What is the function of a 'pallet flow rack' system?
- Allows manual rearrangement of pallets by workers
- Uses gravity to move pallets from a loading end to a picking face (Correct answer)
- Stores pallets vertically to maximize ceiling height use
- Requires powered conveyor belts to move each pallet
Correct answer: Uses gravity to move pallets from a loading end to a picking face
Pallet flow racks use inclined rollers and gravity so loaded pallets slide forward automatically as front pallets are removed, supporting FIFO rotation.
Question 7: In material handling, what does 'dwell time' refer to?
- The time a product spends in transit between facilities
- The length of time a load remains stationary in a location before being moved (Correct answer)
- The duration of a forklift's battery charge cycle
- The period between cycle count intervals
Correct answer: The length of time a load remains stationary in a location before being moved
Dwell time is how long a load sits idle in a staging area, dock, or storage location, and high dwell time can indicate workflow bottlenecks.
