Over the years there has been a gradual shift from the use of symbols that represent certain production operations to the use of words. By documenting your flow process chart as a series of words, it helps to clearly indicate the steps in your process.
What is a HACCP Flow Chart?
A flow process chart is a pictorial representation of a process. Within the food industry, it generally represents all the steps that raw materials go through to become a finished product. Steps in a flow process chart can include Receival of raw materials, store of ingredients, preparation, cooking, cooling, packing, labelling, bulk storage and distribution. Depending on your process, you may have many more or less steps and types of steps than these listed.
Flow Chart Symbols
Traditionally, HACCP flow chart symbols have been used to illustrate the actions within a flow chart. The most common actions are shown below:
Flow Chart Text Boxes
It is more common now to use worded text boxes. This helps to give a better description of the process step and is more also easily understood. Text boxes also allow you to document as much detail about the process step as you need.
Clear documentation
Whatever method you choose to use, the flow chart should clearly indicate all steps in the process. Please ensure that you consider steps involving re-work and services in eg. Water, compressed air (food safety hazards can be identified at these process steps). If you find that you have several processes within a process, a separate flow chart should be documented. Your first level document can be an overview with subsequent layers drilling down into each of these processes.
For more information and guidance on the flow process chart requirements, please check the HACCP certification standard which you have based your HACCP system on.
