Definitions
Data control system refers to monitoring and data gathering systems such as
Systems Control and Data Acquisition (SCADA) software.
Site requirements mean the site specific documented methods for performing work
activities and include health, safety, environmental, and quality management
requirements. They may refer to manuals, codes of practice, or policy statements.

related to site processes.
1.2
Communication methods are identified and their use is explained in accordance
with site requirements.
Range
1.3
The overall system configuration is identified and explained in accordance with
site requirements.
Range
1.4
alarm systems, emergency systems (fire and shut down), radio,

communicated to all affected areas.
5.3
Information is maintained and logged for further action and to provide a
historical record of all events.
Please note
Providers must be accredited by NZQA, or an inter-institutional body with delegated
authority for quality assurance, before they can report credits from assessment against
unit standards or deliver courses of study leading to that assessment.
Industry Training Organisations must be accredited by NZQA before they can register
credits from assessment against unit standards.
Accredited providers and Industry Training Organisations assessing against unit standards
must engage with the moderation system that applies to those standards.
Accreditation requirements and an outline of the moderation system that applies to this
standard are outlined in the Accreditation and Moderation Action Plan (AMAP). The
AMAP also includes useful information about special requirements for organisations
wishing to develop education and training programmes, such as minimum qualifications for
tutors and assessors, and special resource requirements.
