Special notes

1   Definition
    Worksite documentation refers to instructions to staff on policy and procedures
    (including the application of legislation to worksite situations) which are formally
    documented, and are available for reference at the worksite. Examples are standard
    operating procedures, specifications, manuals, and manufacturer's information.

2     Reference
      Competence in this unit standard requires knowledge of the Approved Code of
      Practice for Safety and Health in Forest Operations, Part 5: Timber Stacking,
      Packeting and Transportation (Wellington: Occupational Safety and Health Service of
      the Department of Labour, 1994); available from Bennett’s Government Bookshops
      or online at http://www.osh.govt.nz. This is referred to below as the ‘OSH Approved
      Code of Practice’.

3     The following apply to the performance of all elements of this unit standard:
      a    All work practices must meet recognised codes of practice and documented
           worksite health and safety and environmental procedures (where these exceed
           the code) for personal, product and worksite health and safety, and must meet
           the obligations required under current legislation, including the Health and
           Safety in Employment Act 1992, the Resource Management Act 1991, and their
           subsequent amendments.
      b    All work practices must meet documented worksite operating procedures. This
           includes the recording (by electronic or non-electronic means) of activities,
           events, and decisions.
      c    All evidence of communications gathered in relation to this unit standard must
           be in accordance with worksite procedures for content, recipient, timing and
           method.

Please note

Providers must be accredited by the Qualifications Authority, 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 the Qualifications Authority 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.
