Definitions
Liquid and hazardous waste operations are the collection and disposal of:
a septic waste or sewage;
b grease trap waste;
c any other liquid and hazardous waste product;
see range below.
Evidence relating to one of these types of operations is required.
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.
Site refers to the location of a liquid and hazardous waste holding system/s and their
immediate surroundings from or to which liquid and hazardous waste product/s are
collected or disposed by an operator of a road transport vehicle.
Job instruction refers to a written job order, Dangerous Goods manifest, time sheet,
Waste Service Agreement or other document which describes the waste to be
collected and the collection procedures for a job, and is provided to the operator
before commencement of a job.
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.

Site procedures are practices laid down by the generator, transporter, or disposal site
that must be observed by the operator during the collection of liquid and hazardous
waste.
Working at a height refers to waste collection operations from holding systems that
are at a height of 5 metres or greater.
4
Range
Evidence must be presented for either a standard collection procedure, or for a
special collection situation;
evidence relating to one type of liquid and hazardous waste operation is required;
in special collection situations, evidence relating to one of the following is required –
solvent and/or fuel collection, strong corrosive waste collection, confined spaces
entry, collection while working at a height.
5
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.
Elements and performance criteria
Element 1
Carry out site checks before performing an operation on a liquid and hazardous waste
product.
Performance criteria
1.1
Risks are assessed and actions to minimise them are taken in accordance with
organisational requirements.
Range

solvent; environmental contamination risk, including the effect on
stormwater; risk to the public, including issues such as odour and
fumes; risk to property from splashes and spills; and risk to
personal safety.
1.2
The location of the site and the collection or discharge point(s) are confirmed in
accordance with organisational requirements.
1.3
Drain position (from liquid and hazardous waste generation exit point to septic
tank or grease trap entry point) is located if a blocked drain is encountered
during a standard collection.
Range
1.4
drain position is determined from recorded details such as as-built
plans, on-site investigation.
The capacity of the collection or receiving tank or receptacle is checked in
accordance with organisational requirements.

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.
