CWLP Layout Design 5 — Questions and Answers
Question 1: What does 'floor load capacity' (PSI rating) determine in warehouse layout design?
- Maximum number of employees per square foot
- The types and weight of storage equipment and inventory that can safely be placed on the floor (Correct answer)
- The maximum velocity of forklift travel
- The fire suppression water pressure needed
Correct answer: The types and weight of storage equipment and inventory that can safely be placed on the floor
PSI (pounds per square inch) floor load rating defines the maximum weight per unit area the slab can support, governing storage system and equipment selection.
Question 2: In warehouse layout design, what is the purpose of a 'value-added services' (VAS) area?
- Storage for high-value jewelry and electronics only
- A dedicated zone for kitting, labeling, repacking, or customization activities (Correct answer)
- The area where management offices are located
- A buffer between receiving and shipping docks
Correct answer: A dedicated zone for kitting, labeling, repacking, or customization activities
A VAS area is a designated workspace where products undergo additional processing such as kitting, gift wrapping, labeling, or light assembly before shipment.
Question 3: Which rack configuration best supports FIFO inventory rotation for perishable goods stored on pallets?
- Drive-in rack
- Selective single-deep rack
- Pallet flow (gravity flow) rack (Correct answer)
- Mobile (sliding) rack
Correct answer: Pallet flow (gravity flow) rack
Pallet flow rack uses gravity on inclined rollers to move pallets from the load end to the pick end automatically, ensuring the oldest pallet is always retrieved first (FIFO).
Question 4: A warehouse designer is evaluating a site with 28-foot clear height versus 36-foot clear height. What is the main operational advantage of the taller building?
- Lower heating and cooling costs
- Ability to use taller rack systems and store more inventory without expanding footprint (Correct answer)
- Easier employee supervision from elevated offices
- Reduced building permit requirements
Correct answer: Ability to use taller rack systems and store more inventory without expanding footprint
Greater clear height allows installation of taller racking, increasing storage capacity vertically and reducing the need for costly additional square footage.
Question 5: What is the main risk of designing a warehouse with very high storage density but minimal aisle space?
- Increased theft opportunities
- Reduced throughput and slower picking due to congestion and difficult access (Correct answer)
- Lower fire insurance premiums
- Inability to use barcodes
Correct answer: Reduced throughput and slower picking due to congestion and difficult access
Extremely high storage density limits equipment maneuverability and pickers' access, creating bottlenecks that reduce operational throughput.
Question 6: In a warehouse layout, what is the role of a 'reserve storage' zone versus a 'forward pick' zone?
- Reserve is for damaged goods; forward pick is for new receipts
- Reserve holds bulk inventory replenishing the forward pick zone where active picking occurs (Correct answer)
- Reserve stores seasonal items; forward pick handles daily shipments only
- Reserve is automated; forward pick is always manual
Correct answer: Reserve holds bulk inventory replenishing the forward pick zone where active picking occurs
Reserve storage holds full pallet or case quantities in bulk, and replenishment moves product to the smaller forward pick zone where pickers work efficiently.
Question 7: What layout consideration is most important when designing a warehouse that will handle both hazardous materials (HAZMAT) and standard consumer goods?
- Placing HAZMAT near the main employee entrance for quick access
- Segregating HAZMAT storage with dedicated ventilation, containment, and separate egress (Correct answer)
- Storing HAZMAT at the highest rack levels to prevent accidental contact
- Using the same dock doors for HAZMAT and standard goods to simplify operations
Correct answer: Segregating HAZMAT storage with dedicated ventilation, containment, and separate egress
HAZMAT storage must be physically segregated with appropriate ventilation, secondary containment, and separate emergency egress to meet safety and regulatory requirements.
