CHEMICAL WASTE MANIFEST
1. INTRODUCTION
When submitting a CampusAssist request for the disposal of hazardous waste a chemical waste manifest
must be attached. Up to four manifests can be attached to each CampusAssist request.
The chemical waste manifest is the University’s official record of disposal, the contractor’s transport
manifest and a tool for estimating and managing the cost of disposal. Therefore, it is important to
complete the manifest accurately.
Chemical waste manifests are not used for clinical or anatomical waste. Please contact Safety Health &
Wellbeing to organise the collection of this type of waste.
2. SPECIFICATIONS
The chemical waste manifest is an Excel spreadsheet which contains ‘behind the scenes’ macros and
lookup tables. To ensure full functionality it is best used with Microsoft Office 2010 or later on a Windows
PC. Do not alter or save the manifest as a template. Always download a new manifest from the Safety
Health & Wellbeing website each time you submit a new request.
3. FEATURES
The chemical waste manifest is divided into four main sections:
Only the unshaded cells require data entry. Some of the data must be typed into the manifest while other
information (e.g. Faculty/School, liquid or solid waste type, pack size) is entered using drop down menus.
For each of the four sections describing the waste there are separate and unique prescribed waste types
which can be entered. This is done using a drop down selection.

Ensure a Contact person
and phone number is
entered, especially if
pickup is required from a
specific laboratory and
the contractor will need to
gain access.
The Dangerous Goods
class and UN number
will be automatically
entered.
More rows can be
added to each section
by first clicking on the
cell that is labelled
“Click here” and then
clicking on the button
“Add row” below that
cell.
Do not delete rows.
Four different waste types
• Liquids classified as
dangerous goods
• Liquids not classified
as dangerous goods
• Solids classified as
dangerous goods
• Solids not classified
as dangerous goods
Use this section for unique
container or bag numbers to assist
with the waste identification and
collection process.

4. DETERMINNG WASTE TYPES
To determine the waste type for a specific chemical:
1. Refer to the Safety Data Sheet (SDS). ChemAlert can be used to access SDS.
2. Check the Dangerous Goods (DG) class
Dangerous goods information is available in the transport section of an SDS. If there is more the
one dangerous goods class assigned, refer to the primary class for the purpose of waste
classification.
Types of waste classified as dangerous goods include flammable liquids, corrosives, oxidisers
and acutely toxic substances.
3. Check further for health hazards
The SDS for a hazardous chemical will either state that the chemical is “Classified as hazardous
according to Safe Work Criteria” or provide GHS health hazard classification information.
If the chemical or mixture is not classified as Class 6.1 Toxic, but is hazardous to health, it will be
classified as waste type ‘Liquid-low hazard’ or ‘Solid-low hazard’
Also check if the chemical is a scheduled poison:
•
•
•
S4 pharmaceuticals are classified as Solid- pharmaceutical. Note the schedule number in
the comments column.
S7 poisons, should also be classified as a Dangerous Good, Class 6.1 Toxic and must be
classified with the waste type Liquid –toxic other or Solid –toxic.
S8 controlled drugs cannot be disposed of via this waste stream -contact Safety Health &
Wellbeing for further information.
4. Check concentration
The concentration of a chemical will determine the severity of the hazard. Dilute waste solutions
may be considered as a liquid - low hazard or solid – low hazard waste rather than a dangerous
good. If uncertain, the concentration cut-off values listed in the Hazardous Substances
Information System (HSIS) provide guidance.
5. Assigning non-hazardous waste
If the chemical or chemical mixture is not ‘Classified as hazardous according to Safe Work
Criteria’ or assigned a GHS hazard class it is non-hazardous waste. Use waste types liquid- nonhazardous or solid-non-hazardous.
Waste types and examples are shown in Table 1.
