PURPOSE OF THE UNIT STANDARD 
This standard is aimed at people who work or intend to work in an industry where petroleum and chemical substances (liquids and/or gases) are stored, blended and transferred between tanks. The storage, blending and transferring operations are carried out in tank farms, production depots, distributors or other similar sites.

The principles of storing, blending and transferring petroleum and chemical substances at this level are subsequently the same in terms of the NQF level. The detailed requirements of the specific petroleum and/or chemicals and specific site practices could be considered as variations of context. This means that the standard is applicable in a variety of operations, provided the site-specific instructions (site instructions) used for learning programmes and assessments address best practice and adequate knowledge of the technology applied.
