Lesson 7 - Hygienic Design SAQ
This lesson enables you to test yourself on the material covered in the lesson on Hygienic Design and to determine the level to which you have met the learning outcomes.
Suggested Response - Q3
*Answer the following questions:
a) What is the principle difference between a contact surface and a non-contact surface?
b) What are the main principles to consider when designing buildings and support structures?
c) What are the advantages of having a hygienic drainage system?
Response:
a) A contact surface is any surface which may either directly or indirectly make contact with the product, or from which anything may be drawn back into the product. Note, this includes the packaging material. Non-contact surfaces are not in contact with the product. They can be in the form of the building, ancillary equipment, and supports for equipment.
b) The main principles to consider when designing buildings and support structures are to minimise accumulation of dirt on surfaces, ensure access to all equipment and hygienic finishes for cleanability.
c) Other than improved hygiene, a hygienic drainage system will minimise the amount of cleaning and water required to flush drain systems. If you have an effluent treatment facility the load on the system will also be less. Hygienic drains are designed to be durable and require less maintenance as properly designed drainage will not corrode through normal use.
