Storage equipment

Storage equipment

Below are some points to consider when choosing the type storage systems:

  • Utilization factor

  • Building footprint

  • Effectiveness of space usage

  • Accessibility to unit loads

  • Probability of damage

  • Sprinkler requirement

  • Unit load stability

  • Rotation of unit loads

  • Number of aisles

  • Security
  • Unit loads deep/opening

  • Storage density

  • SKU openings/aisle
  • Throughput volume

  • Stacking height, ft

  • Pick positions

  • Types of pallet

  • Retrieval equipment
Number of unit loads/sku

The leading causes of storage rack system failure, acting alone or incombination, are:
(1) Poor storage rack design – the rack is inherently unsafe;

(2) Incorrect installation and assembly;

(3) Using the wrong material handling equipment to load and unload the storage system;

(4) Operator error when using material handling equipment; and

(5) Structural problems with the floors or walls of the storage area –supporting structures may be overloaded, floors may not be sufficiently level.

Improper records storage can result in disaster. In a large storage system, if one row of shelves tips over, the rest will fall like dominoes. Not only does this nightmare create a mess and necessitate a costly cleanup, it can be life-threatening as well. In storing records it is common practice to use as much vertical (air) space as is practical in order to reduce the need for more valuable floor space. This is economically sound, but it creates a high height to-base ratio, resulting in an unstable rack or shelf system that is more readily tipped or knocked over. Because of this danger, a number of safety measures must be considered when planning a records storage installation.

Some Safety Precaution

- Do not move large racks by yourself. Due to the height and weight of the rack,
Recommends a minimum of two people to accomplish this task

- Before working on the rack, make sure that the stabilizers are secure to the rack, extend to the floor, and that the full weight of the rack rests on the floor. Install front and side stabilizers on a single rack or front stabilizers for joined multiple racks before working on the rack.

- Always load the rack from the bottom up, and load the heaviest item in the rack first.

- Make sure that the rack is level and stable before extending a component from the rack

- Ensure that proper airflow is provided to components in the rack.

- Do not step on or stand on any system/component when servicing other systems/ components in a rack.

- Stack all materials on a flat base.

- Don't stack items so high that they could block sprinklers or come in contact with overhead lights or pipes.

The following are some code requirements and recommendations that apply to many warehouse operations. Specific code requirements will vary depending upon the storage characteristics.



- Automated sprinkler should be considered as standard requirement in any warehouse.

- Storage should be maintained at least 18 inches below sprinkler head deflectors.

- In racked storage, transverse flue spaces of at least 3 inches should be maintained.

- Transverse flue space is the space to either side of a racked pallet.

- In racked storage, longitudinal flue spaces of at least 6 inches should be maintained.

- Longitudinal flue space is the space between the rows of back-to-back rack.

- Racking with solid decking, storage configurations that prevent maintaining the flue spaces, storage of high hazard materials, or storage greater than 40 feet in height will probably require in-rack sprinklers.

- Racking with solid decking, storage configurations that prevent maintaining the flue spaces, storage of high hazard materials, or storage greater than 40 feet in height will probably require in-rack sprinklers.

-In solid piled floor storage there must be an aisle at least every 100 feet and within 50 feet of walls when materials are stored against the wall.



When designing a new system it is recommended to investigate installing a design capable of handling a higher hazard classification. Should storage needs change in the future it can be very expensive to change the existing system to accommodate the higher hazard classification.
