Special notes
1
This unit standard is intended for, but not restricted to, workplace assessment.
2
Safety of personnel and plant must be a priority throughout the assessment. If the
safety requirements are not met the assessment must stop.

Performance and work practices in relation to the elements and performance criteria
must comply with all current legislation, especially the Electricity Act 1992, and any
regulations and codes of practice recognised under that statute; the Health and
Safety in Employment Act 1992; and the Resource Management Act 1991.
Electricity supply industry codes of practice and documented industry procedures
include the Safety Manual – Electricity Industry (SM-EI) Wellington: Electricity
Engineers’ Association. A full list of current legislation and industry codes is
available from the Electricity Supply Industry Training Organisation, PO Box 1245,
Hamilton 3240.

The phrase in accordance with industry requirements is implicit in all elements and
performance criteria in this unit standard.
5
Industry requirements include all asset owner requirements; manufacturers’
specifications; and enterprise requirements which cover the documented workplace
policies, procedures, specifications, business, and quality management requirements
relevant to the workplace in which assessment is carried out.
6
Confined spaces is defined as enclosed or partially enclosed space which is at
atmospheric pressure during occupancy and is not intended or designed primarily as
a place of work. Confined spaces may include but are not limited to spaces that
have: restricted means of entry and exit, an atmosphere which contains potentially
harmful levels of contaminant, an unsafe oxygen level, and the possibility of
engulfment.
Elements and performance criteria
Element 1
Identify hazards and controls within confined spaces in the electricity supply industry.
Performance criteria
1.1
Examples of confined spaces are listed.
Range
1.2
examples of tank-like compartments include but are not limited to
– storage tanks, tankers, process vessels, boilers, pressure
vessels, silos, dryers;
examples of open top spaces include but are not limited to – pits,
pipes, sewers, shafts, ducts;
examples of small hatchway or access pits include but are not
limited to – street sewerage access, power trenches, void spaces.
Evidence is required for three examples from each category.
The main hazards of confined spaces are identified.
Range
hazards potentially causing death or severe injury include but are
not limited to – oxygen deficiency in the confined space, oxygen
excess in the confined space, contaminants on surfaces or in the
atmosphere, operation of moving equipment, uncontrolled
introduction of steam, water, other gas or liquid, suffocation by
solids, electrocution, explosion, fire, chemicals.

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.
