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 transportable 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
A transportable liquid and hazardous waste holding system refers to a container at a
generator’s site within which liquid and hazardous waste may be stored or packaged
and which is transportable by a road transport vehicle.
Liquid and hazardous waste 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.
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 2865:2007 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 transportable holding system for one of the
following types of waste products – septic waste or sewage, grease trap waste, other
liquid and hazardous wastes.

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.
