Explanatory notes
1 Work must be carried out in accordance with organisational requirements, licensing requirements, legislative requirements, and industrial awards and agreements.
2 Workplace information can include Standard Operating Procedures (SOPs), specifications and production schedules.
3 Cooling and hardening equipment may include hardening tunnel, plate hardening machine, jacket holding tank, refrigeration, cooling towers.
4 Confirming equipment status involves checking that hygiene and sanitation standards are met, all safety guards are in place and equipment is operational.
5 Services may include power, water, vacuum, compressed and instrumentation air, refrigeration systems.
6 Monitoring the process may involve the use of production data such as performance control charts.
7 Process operation and monitoring functions may be manual or involve the use of a process control system.
8 Control points refer to those key points in a work process which must be monitored and controlled. This includes food safety (critical) quality and regulatory control points as well as inspection points.
9 Legislative requirements include but are not limited to the Animal Products Act 1999 and Animal Products (Dairy) Regulations 2005, Food Act 1981, relevant codes of practice, and subsequent amendments.

Please note
Providers must be granted consent to assess against standards (accredited) by NZQA, before they can report credits from assessment against unit standards or deliver courses of study leading to that assessment.
Industry Training Organisations must be granted consent to assess against standards by
NZQA before they can register credits from assessment against unit standards.
Providers and Industry Training Organisations, which have been granted consent and which are assessing against unit standards must engage with the moderation system that applies to those standards.
Requirements for consent to assess and an outline of the moderation system that applies to this standard are outlined in the CMR. The CMR 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.
