"... an excellent reference guide and source of information in
assisting myself and my business in developing and providing well
informed, comprehensive and quality Training packages and
Verification of Competency (VOC) tools in the field. ... very much
a planning tool providing information on techniques, shortfalls,
resources, quality assurances, recording and safety"
