The machinery concerned and the extent to which hazards, hazardous situations and events are covered are indicated in the scope of this document. When provisions of this type C standard are different from those which are stated in type A or B standards, the provisions of this type C standard take precedence over the provisions of the other standards, for machines that have been designed and built according to the provisions of the type C standard. It has been assumed that the use of the equipment for dispensing of fuels will be by untrained persons (user / dispenser), while other aspects of the operation, maintenance, etc, will be by designated and trained personnel (station personnel or operator).
