Purpose
This unit standard is for operators of vehicles and equipment used in the
liquid and hazardous waste industry. The term ‘operator’ includes drivers,
supervisors, and owner-operators.
People credited with this unit standard are able to, for a fixed liquid and
hazardous waste holding system, describe design and construction features
that impact on the collection of waste, and carry out checks relating to
accessibility and safety features, integrity and soundness, and capacity and
load size.

Definitions
Fixed liquid and hazardous waste holding system refers to a system at a generator’s
site from which liquid and hazardous waste is collected and transported in a liquid
waste vacuum tanker. Examples of such a system include one or more storage or
containment vessels, pits, tanks, or interceptors.
Liquid and hazardous waste product refers to those waste products that are in a
liquid or sludge state that may be collected and transported in a liquid waste vacuum
tanker or packaged in containers and transported in other vehicles, and which fall
into one of the following categories: readily biodegradable organic material (RBOM);
petroleum products and residues; solvent product and residues; inorganics including
heavy metals and residues; organic materials and residues; and complex organic
materials and residues and intractable materials.
A liquid waste vacuum tanker is a rigid or combination motor vehicle upon which is
mounted a unit for loading, transporting, and unloading liquid, or wet loose matter, or
dry loose products.
Confined space refers to ‘an enclosed or partially enclosed space which:
is at atmospheric pressure during occupancy;
is not intended or designed primarily as a place of work;
may have restricted means for entry and exit;
may – have an atmosphere which contains potentially harmful levels of contaminant;
not have a safe oxygen level; or cause engulfment.
Confined spaces include but are not limited to – storage tanks, tank cars, process
vessels, boilers, pressure vessels, silos and other tank-like compartments; opentopped spaces such as pits or degreasers; pipes, sewers, shafts, ducts and similar
structures; and any shipboard spaces entered through a small hatchway or access
point, cargo tanks, cellular double bottom tanks, duct keels, ballast and oil tanks, and
void spaces, but not including dry cargo holds.’ (AS 2865:2001 Safe working in a
confined space).
Organisational requirements include any legal requirements, standards, codes of
practice, operational and/or site policies and procedures, industry best practice and
manufacturers’ instructions. These should be available to candidates, providers, and
assessors. For this unit standard organisational requirements also includes the
Waste Operators Handbook, which is a subset of the Liquid and Hazardous Waste
Code of Practice, (Wellington: New Zealand Water and Wastes Association, 2003),
available at http://www.nzwwa.org.nz.

While every assessment situation may not provide opportunity for evidence of every
performance criterion, evidence may be obtained over a period of time on the job,
over several assessment opportunities, or through other means such as attestation
and the use of questioning.
5
Range
Evidence must be presented for a fixed holding system for one of the following types
of waste products – septic waste or sewage, grease trap waste, other liquid and
hazardous wastes.

Elements and performance criteria
Element 1
Describe design and construction features of a fixed liquid and hazardous waste holding
system that impact on the collection of waste.
Performance criteria
1.1
Description includes type of materials the holding system vessel is constructed
from, the number of chambers the holding system vessel is divided into, and an
explanation of the relevance of these to waste collection.
1.2
Description identifies inlets and outlets, and explains their method of operation.
Range
may include but is not limited to – inlet, entry or filling point(s),
overflow or safety release point(s), ventilation points, exit or
collection point(s).
1.3
Description identifies the location and explains the method of operation of any
escape routes from the holding system vessel.

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.
