Fact Sheet
A clandestine drug laboratory
has been detected on my
property what happens now?
Clandestine drug laboratories (clan
labs) are premises or vehicles in
which unlawful manufacture or
attempted manufacture of controlled
drugs such as methamphetamine
have occurred, or where chemicals,
equipment or waste materials related
to unlawful manufacture of a
controlled drug have been located.
Clan labs that are detected by police are notified to public health authorities.
The unlawful manufacture of controlled drugs can result in long-term contamination of
premises. As this contamination is potentially hazardous to human health, the property owner
must ensure premises where a clan lab has been detected is safe before they can be
reoccupied.
Why are clan labs a risk to public health?
Clan lab operators use improvised equipment, materials and methods during the drug
manufacture process and may illegally dispose of waste products. This can result in significant
and widespread chemical contamination throughout a property. Exposure to these chemicals is
considered a serious risk to health as many of the chemicals are toxic, flammable and/or
corrosive. Short-term exposure to these chemicals can result in nausea, vomiting, headaches
and chest tightness, while long-term exposure can result in severe skin irritation, insomnia,
irritability, hyperactivity, behavioural changes, and adverse cardiovascular effects.
Given the health risks posed by these chemicals, it is important that occupation of premises
where a clan lab has been detected is prevented until the nature and extent of the chemical
contamination is assessed and any required remediation has been completed.
What happens when a clan lab is detected?
When a clan lab is detected, the police will investigate and seize equipment and other items as
evidence to support any legal proceedings. The police then notify the relevant public health
authority to ensure any potential public health risks in the property are addressed.
If a clan lab is identified on a property, do not touch it or attempt to shut it down.
Immediately contact police by telephoning triple zero (000) so that experts who are properly
trained in the safe dismantling and handling of equipment and products used in the
manufacturing process may be dispatched. Attempts to shut down or dismantle an active clan
lab may result in injury or death.
What happens when public health authorities are notified?
A site assessment notice under the South Australian Public Health Act 2011 will be issued on
the property owner by the relevant public health authority (usually the local council), requiring
the property owner to:
prevent occupancy of the premises. The relevant public health authority may also work in
partnership with the Housing Safety Authority to ensure occupancy of residential premises
is prevented; and
OFFICIAL
assess the level of chemical contamination present in the premises by engaging a
suitably qualified expert to conduct a sampling program and prepare a report on the
methods and findings of the sampling program and, if necessary, provide remediation
recommendations (a remediation action plan).
If the report indicates that contamination is present and remediation is required, a site
remediation and validation notice under the South Australian Public Health Act 2011 will be
issued on the property owner by the relevant public health authority requiring the property
owner to:
remediate the premises by engaging a suitably qualified expert to clean and/or remove
contaminated materials.
confirm that the remediation was successful by engaging a suitably qualified expert to
conduct further sampling to make sure the contamination has been removed and the
premises is safe to reoccupy.
Penalties apply for non-compliance with a notice (maximum penalty $25,000). Also, if the
requirements of a notice are not complied with, the relevant authority may take any action
specified in the notice and recover the costs from the owner of the premises.
To prevent the inadvertent/unwitting purchase or rental of a property that has been used as a
clan lab and has not yet been assessed or remediated, SA Health and the Housing Safety
Authority flag all notified clan labs on the South Australian Integrated Land Information System
(SAILIS).
Local councils may also flag notified premises for the purposes of section 7 searches under the
Land and Business (Sale and Conveyancing) Act 1994. Flagging these properties means that
prospective buyers of properties may be made aware of the potential ongoing health risks
associated with the property and are duly informed of any legal obligations they may take on in
relation to the assessment and remediation of the premises.
The Housing Safety Authority will place the property on the Substandard Properties Register
and may also take formal action to prevent the occupation of the premises until it is deemed
safe.
How do I find someone to assess chemical contamination?
As residual contamination may be present even when there is no apparent odour or visible
staining associated with the drug manufacturing process, specialist technical expertise and
equipment is required for the assessment of clan labs.
To ensure a clan lab assessment is conducted appropriately and in accordance with legislative
requirements, it must be performed by a suitably qualified expert (assessor) with experience in
the fields of environmental engineering, environmental science, environmental health, or
occupational hygiene, and who is in possession of tertiary qualifications in one of these
disciplines from a recognised educational institution (a recognised university).
Assessors can be found through:
an internet search
relevant certified membership organisation such as the Australian Institute of Occupational
Hygienists https://www.aioh.org.au/resources/consultants/
It is important to confirm that the qualifications and experience of prospective assessors meet
the mandatory requirements of the relevant South Australian legislation.
If your property is insured, you should check with your insurance provider to determine if your
policy covers you in these circumstances. Your insurance provider may also be able to
recommend a suitable assessor.
OFFICIAL
How do I find someone to remediate (clean) chemical
contamination?
As the remediation of clan labs involves specialist techniques (which extend beyond a general
clean), it is important that remediation service providers (specialist industrial cleaners) are
sufficiently knowledgeable and experienced to undertake the work required as per the
remediation recommendations made by the assessor. Suitable remediation service providers
can be found through an internet search.
To prevent conflicts of interest, remediation service providers should have no association with
the assessor(s) and should not be engaged by the assessor. Similarly, remediation service
providers should not engage the assessor to perform post remediation validation sampling.
How is contamination of my property assessed?
To assist in determining the presence and degree of any chemical contamination, there are
National Guidelines that outline the sampling program that must be undertaken by an assessor.
In summary, the sampling program must include (as a minimum):
taking at least five surface samples from within the premises and submitting them to a
suitable laboratory for quantitative assessment.
taking and testing surface samples from areas that show evidence of contamination,
surfaces used in the drug manufacturing process and any room inhabited by a child less
than 16 years of age.
testing for volatile organic compounds throughout the premises.
taking at least two soil samples from areas where there is evidence of soil contamination or
near well-travelled paths.
Assessors must follow the sampling program described in the National Guidelines and provide
the premises owner with a written report which outlines the results and the remediation steps to
be implemented to reduce the health risks to acceptable levels. To assist in the development of
the sampling plan, local council officers and premises owners are encouraged to provide the
assessment service provider with any relevant available background information on the clan lab
(e.g., the notice and attachments issued by the local health authority).
What services should I expect from an assessor?
Preliminary assessment At least five surface samples from within the premises will be
taken and tested, testing will be undertaken for volatile organic compounds (VOCs)
throughout the premises and soil samples (minimum of two) will be taken for testing from
areas where there is evidence of soil contamination or near well-travelled paths. Indoor and
outdoor areas of the property will be assessed, after which a detailed preliminary
assessment report will be provided.
Remediation action plan (RAP) When a preliminary assessment report shows that
investigation levels have not been exceeded, remediation is not required. However, it is
recommended that the property is generally cleaned. If the preliminary assessment report
shows investigation levels (detailed on page 28 of the National Guidelines) have been
exceeded, a RAP will be developed by the assessor detailing all the actions recommended
to reduce risks to acceptable levels and establish safeguards to complete the remediation
in an environmentally acceptable manner.
Post clean/remediation assessment Once the clean has been completed, the assessor
will conduct a site validation to ensure that the objectives stated in the RAP have been
achieved. The assessment will include but not be limited to the following: a general
inspection of the site, re-sampling of all surfaces from which initial samples were taken
where results exceeded investigation levels, sampling of areas which are expected to have
frequent contact (for example kitchens and bathrooms) and sampling for VOCs where
required. Ideally, the same assessor will conduct the pre and post remediation
assessments.
OFFICIAL
Validation report The details of the site validation and clean up report are compiled and
presented in a validation report. This report will be assessed by the public health authority
to ensure the property has been remediated successfully and the post remediation sample
results are below the investigation levels. A satisfactory report will result in the removal of
notices and the flags placed on the property on SAILIS by SA Health, the local council, and
the Housing Safety Authority, and the property will be removed from the Substandard
Properties Register.
