Industrial Ergonomics:
Storage of Material

What is the proper way to set up a warehouse from an ergonomic point of view?  All too often the warehouse becomes a storage area for a company that is growing or changing too quickly.  Unfortunately, this poor design can often lead to physical problems with the worker.  So what are some things to do and consider in the warehouse?

First, ask yourself just what are you storing?   In particular what is the size and weight of the objects?  Many times they will vary but you need to set some parameters to know what you are dealing with.  Next ask yourself, which items seem to move the most?  In other words, what are you constantly moving in and out of the warehouse (WH)?  Frequency of use is a key indicator in the storage and positioning process.

With this information in hand you can now begin to develop a shelving plan.  Items that are rarely needed should not be stored in the front and center position.  Likewise, items that weigh the most, should not be stored in the farthest reaches of the WH.  The goal is to assess the size and space then position the products based on frequency of need.  Once you have a basic positioning chart, the next step is to address shelving requirements.

Client Example #1: Maneuvering 80 lb. bags from the WH into the laboratory.

The shelf was designed at at height that was just above the push cart used to carry the bag into the lab.  Simplicity at its best. The client would slide the bag onto the cart and roll it to the required destination.  NOT LIFTING WAS INVOLVED.  Now not every WH can be structured this way, but many can and aren't.

bulletERGO TIP: The key to remember is the RED, YELLOW & GREEN Zones when it comes to lifting.  Using your arms as the measuring too, the GREEN Zone is that area from your finger tips when arms are at your side, hands open, to your arm pits.  The YELLOW Zone entails the area that covers from your arms being extended between the arm pits and the finger tips or mid-thigh area.  The RED Zone is the areas that are below the mid-thigh to the floor and above the arm pits or with arms extended above the head.

Client Example #2: Using ladders, carts or lift jacks in multiple WH sections.

This client had a rolling ladder to obtain items on the upper shelves.

bulletERGO PROBLEM: Unfortunately the ladder could not pass from one area of the WH to the other so it you were in the second section and needed to reach something up high, you were in trouble.  The WH had expanded so rapidly that adjacent space was acquired and passage way was created for employees to go from one section of the WH to the other.  Unfortunately, not one remembered to address accessibility and the space was too small for the large rolling ladder to get into the other WH.

When storing material assess:

bulletThe size and weight of objects: Can they be purchased in different sizes?
bulletThe frequency of use: How often are the obtained or used?
bulletThe storage structure itself and the way the objects are positioned: Can this be improved?
bulletThe accessibility & postures required to obtain the objects.
bulletThe types of equipment available to assist: ladders, carts, jacks, etc.
