3. Handling and Storage Equipment

4. Why stack?

5. Stacking Methods
Unbonded Stacking
Bonded Stacking

6. Stacking Methods Clean area before creating stack
Use good and clean pallets
Select stacking method
Identify space for spoiled and empty packaging
Identify space for reconditioning & repackaging damaged cargo
Use stack card

7. Bad Practices
The stack should be built to give a firm bonded or interlocked stack
Do not stack so high that packages at the bottom are crushed or split
Do not throw or drop X
Remove projecting nails and splinters or the bottom bags may be torn and food spilt
Do not stack too close to the roof reducing ventilation and access
Do not stack close up to, or on top of, the roof beams so as to risk damaging the structure

8. Stock Location: Racked

9. Handling of Hazardous Material
Hazardous materials include (but not limited to):
Pesticides
Corrosive Material
Fuel & Lubricants
Considerations
National Legislation and Regulations
Environmental Concerns
Staff Safety
Additional Security Measures
Gas Cylinders

12. Volume (cbm) / Weight (mt)
Stowage factor
What is stowage factor?
How do you calculate it?
Volume (cbm) / Weight (mt)
You have received a commodity in boxes with the following characteristics:
Height 15cm
Width 45cm
Length 60cm
Weight mtn
What is the stowage factor of this commodity?

13. Exercise (A) : Capacity of a Warehouse
In groups, list on flip charts what elements of one of the categories below would constrain the supply chain
1 a) What is the floor space in a warehouse that is 32 m long and 10 m wide?
1 b) What is the volume / "theoretical storage capacity" of a warehouse that is 32m long and 10m wide and 4m high?
2) Calculate the total "usable volume" of the warehouse when it has four (4) stacks as pictured below of the same size. Maximum storage height: 4m
3) Calculate the total occupied space (in MT) of the warehouse filled with the commodities indicated. 1m

14. Exercise (B) : Capacity of a Warehouse
If time permitted
4) Calculate the stack capacity for the following:
Rice in 50 kg bags with a stowage factor of 1.4cbm/mt
You have 70 pallets (size 0.9m x 1.2m)
Maximum storage height: 3m
5) What is the minimal number of pallets (0.9m x 1.2m) required to store 200mtn of a commodity that has a stowage factor of 2?
Maximum storage height: 2.5m
How many pallets will you need to square off the surface of the pallets?
What are the surface dimensions of the stack?

15. Answers (A): Capacity of a Warehouse
1 a) Ground surface:
32 x 10 = 320 sqm
1 b) Theoretical storage capacity:
32 x 10 x 4 = 1280 cbm
2 Usable volume:
Working space = (32 x 1 x 3) + (10 x 1 x 3) = 126
Usable volume = (320 – 126) x 4 = 194 x 4 = 776 cbm
3) Occupied space (All stacks have the same dimension)
Stacks volume = 3.5 x 14.5 x 4 = 203 cbm
Rice occupied space = 203 / 1.4 = 145 MT
Kitchen Kits occupied space = 203 / 2.3 = 88.3 MT
Wheat occupied space = 203 /1.7 = MT
Blankets occupied space = 203 / 4.5 = 45.2 MT
Total occupied space:
= 398 MT

16. Answers (B): Capacity of a Warehouse
If time permitted
4) Stack capacity calculation:
Surface on the ground = 0.9 x 1.2 x 70 = 75.6 sqm
Maximum capacity (cbm) = 75.6 x 3 = sqm
Maximum capacity (MT) = / 1.4 = 162 MT (of rice)

17. Answers (B): Capacity of a Warehouse
If time permitted 5)
How many pallets will you need to square off the surface of the pallets?
Required Volume: 200mt * 2 = 400cbm (stack capacity*stowage factor)
Required Surface: 400cbm / 2.5m = 160sqm (required volume/ maximum storage height)
Surface of a pallet: 0.9m * 1.2 m = 1.08sqm
Minimal number of pallets: 160sqm / 1.08sqm = 148 (required surface/ surface of pallets)
Actual pallets to be used: 150 (in order to form a rectangular stack, 12X12 pallets =144, 12X13 pallets=156, 11X14=154 etc)
What are the surface dimensions of the stack?
Surface Dimension of Stack: 12m x 13.5m (10 pallets X 1.2m and 15 pallets x 0.9m)
There might be other options as well depending on how the warehouse is organized, but in the drawing above the 13.5m wide and 12m long would probably be the best.
Other examples: 9m x 18m (10 pallets x 0.9m and 15 pallets x 1.2m) – but not optimal with the given warehouse dimensions.
