Any representation, statement, opinion or advice, expressed or implied in this information paper is
made in good faith but on the basis that the State of Queensland, its agent and employees are not

case may be) action in respect of any representation, statement or advice referred to above.
1. Introduction
Flammable and combustible liquids (FCL) constitute by far the largest group of hazardous
materials used in Queensland. The most common FCL in the community are petrol, kerosene
and diesel fuel.
Because of the risk posed by their potential to cause or exacerbate a fire and their widespread
presence throughout the community, a licence is required for the storage of FCL in excess of
minor quantities.
This information paper provides information on licensing of the storage of FCL under the
Dangerous Goods Safety Management Act 2001 (DGSM).
DGSM legislation
The DGSM legislation establishes requirements for the safe storage and handling of
dangerous goods and combustible liquids. Generally, these requirements (or obligations) are
performance-based, i.e. they set goals that must be met but do not prescribe how they are to
be met. Obligation holders are required to achieve an acceptable level of risk as far as
reasonably practicable.
Occupiers of premises have the obligation to store and handle their dangerous goods and
combustible liquids at an acceptable level of risk. On the basis of the type and quantity of
these materials stored, premises are classified as a Dangerous Goods Location (DGL), a
Large Dangerous Goods Location (Large DGL), “other” workplace or Major Hazard Facility
(MHF). The obligations of occupiers relate to the level of classification of the premises.
Licensing
Authority is devolved to local governments to license premises where FCL are stored, and to
set and enforce conditions of licence.
Australian Standard AS1940 “The storage and handling of flammable and combustible
liquids” plays a key role in determining whether a FCL licence is required or not. The
licensing provisions apply to premises where AS 1940 applies and where the quantity of FCL
stored exceeds the minor storage exemption limits set out in that standard.
For the manner in which FCL are stored, adherence to AS 1940 is not required. However,
one way of achieving an acceptable level of risk is to comply with good industry practice,
which may be expressed in an accepted standard such as AS19401. Hence, AS 1940 is seen
as a valuable source of technical guidance.
A licence holder must comply with the requirements of the DGSM Act and Regulation and
with the conditions of the licence.
FCL licence conditions are enforced by authorised officers from the local government that
issued the licence. Thus any queries regarding licensing for the storage of FCL should be
directed to the relevant local government.

Other suitable standards may be used; e.g. for laboratories, AS 2243 “Safety in laboratories”, especially Part
10.

2. Who needs a Licence?
The occupier of premises intending to store FCL above minor storage quantities as specified
in AS1940 and not exempted by the Act or Regulation must apply for a licence. The
application on the approved form must be made to the local government where the premises
are situated.
In order for the local government to determine if a license should be granted to the occupier,
sufficient information must be provided about the storage facility as well as the occupier, in
order to determine their suitability.
A licence is required if the quantity of FCL exceeds the minor storage limits stated in Table
2.1 of AS1940. This quantity can be in underground tanks, aboveground tanks, packaged
goods stores or a combination of these. The information in Table 2.1of AS 1940 is given in a
rearranged format as a reference in Appendix 1 of this information paper.
AS 1940 sets out requirements for the design, construction and operation of installations for
the storage and handling of FCL in locations that are generally industrial, commercial or rural
in nature. It includes matters relating to operations and management of emergencies. It
identifies issues to be considered in any risk management of facilities handling FCL.
℡ To purchase a copy of AS1940 or any other Australian Standard, contact
Standards Australia on 1300 654 646.
-- Note that a new version of AS1940 was released October 2004 -Note that licensing provisions also apply to the following liquids:
•
•
Class 3 liquids that have a subsidiary risk assigned (e.g. methanol Class 3 sub risk 6.1);
Dangerous goods of other classes that possess a subsidiary flammable liquid risk
(e.g. glacial acetic acid Class 8 sub risk 3, or selected pesticide products of class 6.1, sub
risk 3).
An occupier must include the quantities of materials that have a flammable subsidiary risk
when determining obligations under DGSM Act and whether licensing is required.
The factors determining whether a site requires a licence include:
•
•
the flashpoint and classification of the material (i.e. Packing Groups I, II and III, and
combustible liquid types C1 and C2); and
the maximum quantities stored at any one location, either as a total or as the amount per
unit floor area.
The quantity thresholds above which a licence is required depend on the type of premises, the
floor area of the premises and in some cases whether the storage is inside or outside. The
types of premises are as follows:
•
•
•
•
commercial building
hospital
educational establishment
laboratory

CHEM services, Department of Emergency Services
Page 2
•
•
•
•
•
factory or workshop
shop
warehouse
service station or
open land.
Under the DGSM legislation, a FCL licence is not required in the following situations:
•
•
for coal mines, mines, petroleum leases and gas pipelines (Act, s. 3); and
for rural places (land exceeding 5 ha in area used exclusively for agricultural,
horticultural, floricultural or pastoral purposes, unless the FCL is stored for resale)
(Regulation, s.78).
Because the AS 1940 minor storage exemption limits are different from the quantity
thresholds for DGLs, it is possible that premises may be regarded as a minor storage
workplace for the purposes of Part 3 of the DGSM Regulation but still require an FCL
licence.
An example would be a warehouse storing 8,000 litres of C1 combustible liquids in packages
inside the building. Under Table 2.1 of AS 1940, this quantity exceeds the minor storage
exemption limit of 2,000 litres; the premises would require an FCL licence. However, the
quantity does not exceed the relevant DGL threshold (50,000 litres - Item 7 of the Table in
Schedule 1 of the DGSM Regulation), and so is a minor storage workplace.
Conversely, premises classed as a DGL because of the quantity of FCL stored would not need
a licence if the quantity of FCL did not exceed the AS 1940 minor storage exemption limits.
An example would be open land with a 2,000 litre tank containing PG III flammable liquid.
This premises exceeds the DGL threshold of 1,000 litres but not the AS 1940 exemption limit
of 5,000 litres.
As the licensable quantities of FCL vary for different types of premises, as shown in Table
2.1 of AS 1940, any person who is proposing to store FCL is advised to contact their
local government to determine if they require a licence.
2.1
Conditions of Licence
A licence may be issued only if the following criteria are met:
•
•
the premises are suitable for the proposed storage of FCL; and
the applicant is a suitable person to hold a licence.
The local government may approve the application provided the site achieves an acceptable
level of risk. This may be demonstrated by complying with accepted standards or by the
applicant carrying out a suitable risk study.
The licence may be issued subject to conditions stated in the licence which must be complied
with at all times while the license is valid. The occupier of the site may then store FCL at the
site in compliance with the licence conditions set for the site.
DGSM Information Paper No. 11 Licensing of Flammable and Combustible Liquids Storage (March 2005)
CHEM services, Department of Emergency Services
Page 3
Under the DGSM Regulation (s.92), it is a condition of licence that the licensee must comply
with the DGSM Act. The quantity of FCL stored must not exceed the quantities stated in the
licence. The local government may set appropriate conditions on the licence to give effect to
the DGSM Act.
2.2
Administrative processes
The Regulation makes provisions for the renewal, amendment and transfer of licences as well
as their suspension or cancellation.
3. Minor Storage
Any storage of FCL in quantities not exceeding those listed in Table 2.1 (Section 2) of
AS1940 is classified as minor storage.
The underlying concept of minor storage for the purposes of AS1940 is that quantities below
a certain level are so small, or so scattered and separated, that they present little risk, add little
to a building’s fire load, and are generally unlikely to play a significant part in spreading a
fire from place to place. The fire-fighting facilities required under normal building
regulations are expected to cope adequately.
Minor storage may exist at a site at which no other FCL are present. It may also exist at a site
where major quantities of FCL are present but the minor storage is separated from those
quantities.
There may also be more than one minor storage at the one site. Section 2 of AS1940 (Minor
Storage) provides guidance on multiple minor storages in the same building and/or same site,
including proximity to other stores. This guidance indicates the degree to which FCL may be
accumulated in a small area within minor storage limits. The requirements also apply to
minor storage on construction sites.
Under the DGSM Regulation (Part 4), storage of quantities below the limits in the Minor
Storage Table does not require the site to be licensed provided the following precautionary
measures as stated in AS1940 Section 2 (Minor Storage) are complied with. The following
information is taken from Section 2.3 Precautions applying to minor storage.
Location of minor storage
The following requirements and recommendations apply to the location of an indoor minor
storage:
(a) If the storage is located on a floor that is above the building’s lowest floor (i.e. on a floor
that is above the ground floor or basement), its location shall not jeopardize the safety of
any areas on lower levels of the building or impede firefighting operations.
(b) Flammable vapours and spilt liquids shall be prevented from escaping to any lower levels
of the building.
(c) Concentrated storage of liquids in any one area shall be avoided, so as to reduce the fire
load and the potential rate of fire spread.
(d) The storage area shall be adequately ventilated.
(e) The build-up of flammable vapours should be avoided (see Control of ignition sources).
DGSM Information Paper No. 11 Licensing of Flammable and Combustible Liquids Storage (March 2005)
CHEM services, Department of Emergency Services
Page 4
Operations
The following handling requirements and precautions apply:
(a) Persons who handle the liquids shall be fully aware of the hazards involved.
(b) All storage areas shall be secured against access by unauthorized persons at all times.
(c) Packages shall not be placed where they could hinder escape from a building in an
emergency.
(d) Care should be taken when decanting or transferring flammable liquids. Dispensing
pumps or self-closing metal taps should be used, in order to reduce the hazards of splash
filling, spillage and vapour escape.
(e) Packages shall be kept closed when not in use. Packages containing flammable liquids
should only be opened or decanted in well-ventilated areas and away from any potential
ignition source.
(f) The area in or around the minor storage shall be kept free of combustible materials and
residues.
(g) Any materials that might react dangerously if mixed shall be kept apart so that the
possibility of reaction is minimized, e.g. fuel and pool chorine.
(h) Liquids should not be stored near any hot surfaces, e.g. steam pipes, furnace walls or
engines, or where they might be accidentally exposed to heat, e.g. from escaping steam.
(i) Liquids should be transferred and moved in manner that reduces the likelihood of
spillage, vapour escape or fire.
Control of ignition sources (flammable liquids only)
Except for domestic premises, AS/NZS 2430.3.3 shall be consulted for hazardous
atmosphere zoning if the volume of flammable liquids exceeds—
(a) 100 L in closed containers;
(b) 25 L for decanting purposes, e.g. petrol transfer to a motor vehicle or lawn mower;
(c) 5 L in open containers for occasional use; or
(d) 1 L in open containers for continuous use.
There shall be no ignition sources in any space in which a flammable mixture of vapour and
air could be present.
WARNING: EVEN SMALL QUANTITIES OF FLAMMABLE LIQUID CAN CREATE A VAPOUR
CLOUD THAT CAN TRAVEL CONSIDERABLE DISTANCES AND FLASHBACK TO ITS POINT OF
GENERATION IF IT MEETS A SOURCE OF IGNITION. THIS IS PARTICULARLY THE CASE WHEN
DECANTING OR IF THE LIQUID IS SPILT.
Spillage Control
All spills and leaks shall be cleaned up immediately. Any waste shall be disposed of safely
and in accordance with the local regulations. Liquids should not be allowed to reach ignition
sources, stores of other chemicals, or combustible materials (e.g. timber and paper), or flow
into drains or onto neighbouring land, or enter any creek, pond or waterway. Precautions
should be based at least on the loss of contents of the largest container kept.
A simple spillage kit may consist of—
(a) a metal bin with a tightly-fitting lid (plastics can be attacked by the liquid), partially filled
with non-combustible absorbent such as vermiculite;
(b) broom, shovel, face shield, chemically-resistant boots and gloves; and
(c) a suitable respirator.
Oils of animal or vegetable origin can oxidize, with the generation of heat and the possibility
of spontaneous ignition if they are absorbed onto combustible absorbents.

Fire protection and warning signs
At premises other than residences or farms, in locations where more than 100 L of flammable
liquids, or more than 1000 L of combustible liquids are stored, or where flammable liquids are
decanted, the following requirements apply:
(a) At least one portable fire extinguisher, having a suitable rating for use with the range of
materials being kept, shall be readily accessible and adjacent to the minor storage area.
Where liquids are stored on open land, a fire extinguisher shall be provided if the liquids
are decanted or transferred within 5 m of the storage.
(b) In areas where flammable liquids are decanted, a sign bearing the words
DANGER - FLAMMABLE LIQUID - NO SMOKING - KEEP FIRE AWAY
shall be displayed.
NOTE: Signs should comply with AS 1319.
For retail areas with customer access, this requirement shall apply if the liquids are
decanted or transferred, or are in packages having capacities of more than 25 L.
A flammable liquid storage cabinet is designed
for storage of small quantities of flammable liquids.
AS1940 provides requirements for these.
Figure 1 is an example of a flammable liquid
storage cabinet.
AS1940 Section 2 also states conditions for minor storage on open land and storage in tanks.

4. Classification of flammable and combustible liquids
The words “flammable” and “combustible” have a very specific meaning within the context
of fire prevention and suppression. In general, a flammable liquid burns more easily than a
combustible liquid.
More specifically, the Australian Dangerous Goods (ADG) Code makes the distinction
between a flammable liquid and a combustible liquid based on the liquid’s flash point and
boiling point. The division between flammable and combustible occurs at a flashpoint of
60.5oC. That temperature represents the upper limit of ambient temperature one might expect
to encounter in all but the hottest climates. Liquids with a flash point below 60.5oC are
flammable.

III
Flash point (closed cup)
<23 oC
>23oC - 60.5oC
Initial boiling point

The ADG Code states that flammable liquids are liquids, or mixtures of liquids, or liquids
containing solids in solution or suspension (e.g., paints, varnishes, lacquers) that give off a
flammable vapour at temperatures of not more than 60.5oC (closed cup test), referred to as
the flash point. Liquids meeting this criterion but with a flash point of more than 35oC that do
not sustain combustion are not flammable liquids for the purposes of the ADG Code.
Flammable liquids also include:
•
liquids offered for transport at temperatures at or above their flash point; and,
•
substances that are transported at elevated temperatures in a liquid state and that give off
a flammable vapour at a temperature at or below the maximum transport temperature.
Note: The flash point of flammable and combustible liquids may be altered by the presence
of an impurity. Generally the flash point is quoted for a chemically pure substance. However,
hydrocarbon liquids such as fuels and oils are composed of more than one type of
hydrocarbon and hence the value quoted may vary depending on the relative composition.
Commercial products may contain added substances or impurities, and hence flash points
may vary. It is for reasons such as these that a range may be quoted for a flash point rather
than a single value. This may have an effect on classification or determination of the Packing
Group for the material. If there is doubt as to the flash point and thus the materials
classification (details should be found on the product’s MSDS3), then check with the supplier,
otherwise a flash point test should be performed by a reputable laboratory.

The Packing Group indicates the degree of danger presented by the substance when it is in its correct
packaging during the course of transport. The packing groups are:
PG I
- items presenting great danger
PG II
- items presenting medium danger
PG III - items presenting minor danger

Viscous flammable liquids
As stated in the ADG Code4, viscous flammable liquids such as paints, enamels, lacquers,
varnishes, adhesives and polishers with a flash point of less than 23oC are included in
Packing Group III provided that:
a)
b)
c)
less than 3% of the clear solvent layer separates in the solvent separation test; and
the mixture does not contain any substance with a primary or a subsidiary risk5 of Class
6.1 or Class 8; and
The viscosity and flash point are in accordance with Table 2 shown below.

For further information on classification of flammable liquids, refer to the ADG Code,
Addendum to Appendix 2, Assignment of Packing Groups Class 3, Vol 2 pp 21-24.
Manufactured product is a Class 3 dangerous good of Packaging Group II or III, being a
suspension or solution of a least 10% nonvolatile materials as determined by AS 1580,
Method 301.1, of which less than 3% of the mobile solvent layer separates in the solvent
separation test specified in Clause A6.2(a) of AS 1940 and the following viscosity criteria:
a)
a viscosity of at least 250 centistokes at 23°C; or
b)
requires stirring before use and has a viscosity of at least 20 centistokes.
The term “manufactured product” essentially refers to paint products.
These classifications help define the basis required under AS 1940 required for storage of
flammable and combustible liquids to meet requirements of the legislation.
Combustible Liquids
A Combustible liquid is defined as any liquid other than a flammable liquid that has a
flashpoint, and that has a firepoint less than its boiling point. For the purposes of AS1940,
combustible liquids are divided into two classes as follows:
Class C1 - a combustible liquid that has a flashpoint of 150°C or less, i.e. >60.5°C, <150°C.
Class C2 - a combustible liquid that has a flashpoint exceeding 150°C.
C1 and C2 are not to be confused with Class 1 or Class 2 dangerous goods. Combustible
liquids are not considered to be dangerous goods whereas Class 3 flammable liquids are.

(Note - there may be Town Planning restrictions on the storage of dangerous goods in residential areas)
NOTES:
• In the case of laboratories, commercial buildings and the like, this Table is intended to cater for the day-to-day working stock in the laboratory or
workroom. If these quantities are to be exceeded, it will be necessary to install a cabinet or major store facility according to the scale needed.
•
It is permissible to store at the same time on the same area, the maximum permissible allowance for each or all of the other classes of liquids.
•
Where the maximum allowance is specified in terms of quantity per unit area, any arrangement which results in concentration at one point should be
avoided. Such aggregation contravenes the intent of minor storage, which is dispersal, and additional storage provisions may be required.
