APPENDIX A Controlled Substances (Scheduled Drugs and Poisons)
APPENDIX B Security Sensitive Ammonium Nitrate (SSAN)





1.1 These procedures outline the basic principles for managing the purchase, storage, use and disposal of hazardous substances, dangerous goods, and controlled substances at Flinders University. The term Workplace Substances will be used throughout these procedures as the collective term for these categories.

1.2 The overarching principle is to provide a systematic method for identifying and controlling potential hazards associated with workplace substances in order to minimize the risk of adverse health and safety effects to people, the environment or property.



2.1 These procedures apply to all staff, students, contractors and visitors at all workplaces owned, managed or controlled by Flinders University, including field activities involving University staff and students.



For the purpose of these procedures the following definitions apply:

'ChemWatch' - The chemical database used by the University to assist with the management of workplace substances.

'Controlled Substances (or Scheduled Drugs and Poisons)' - Substances which require licensing under the South Australian Controlled Substances Act 1984.

'Dangerous Goods' - Substances that are defined by the Dangerous Substances Act, 1979, to be dangerous. Dangerous Goods are classified on the basis of immediate physical or chemical effects that may impact on people, property or the environment - explosive, flammable, corrosive, chemically reactive, highly combustible, acutely toxic, radioactive or infectious.

'Hazardous Substances' - Substances that are

  • listed on Australian Safety and Compensation Council (ASCC) list of Designated Hazardous Substances, or
  • determined to be a hazardous substance by the manufacturer or importer of the substance on the basis of the ASCC Approved Criteria for Classifying Hazardous Substances.

In general, hazardous substances contain ingredients that may be harmful to health in the medium or long term. This includes substances that are lethal and non-lethal, corrosive, toxic, irritant, sensitising, mutagenic, teratogenic or carcinogenic. The concentration level of each ingredient in a mixture is taken into account in determining whether the mixture as a whole is determined to be hazardous.

'Material Safety Data Sheet (MSDS)' - Information sheets that provide technical information in relation to substances. These sheets are obtained directly from the manufacturer or through the University's ChemWatch MSDS database.

'Security Sensitive Ammonium Nitrate (SSAN)' - (a) ammonium nitrate; or (b) ammonium nitrate mixture at greater than 45% mass per mass mixed with any other substance, but not in solution.



4.1 Cost Centre Heads

Responsible for ensuring that

  • systems and procedures for workplace substances management are implemented, monitored and reviewed in their Cost Centre; and
  • there are adequate resources for effective workplace substances management in their Cost Centre, including the appointment of one or more Workplace Substances Managers for the Cost Centre.
4.2 Managers/Supervisors of areas

Responsible for ensuring that

  • their area has a planned programme of purchasing, identification, assessment, control and monitoring of workplace substances to meet legislative and University policy and procedures requirements;
  • there is adequate consultation with Health & Safety Representatives in matters that may affect the work group regarding workplace substances.
4.3 Workplace Substances Managers Responsible for coordinating the management of workplace substances within their designated area.
4.4 Supervisors

Supervisors of staff and students who are handling workplace substances must ensure that these people are fully instructed and trained in hazard management principles, MSDSs, control measures, safe work practices and any other measure to minimize risk.

Supervisors must also ensure that

  • the local Workplace Substances Register and MSDSs are readily available to any staff member/student who may be exposed to any locally used workplace substance during their work or study;
  • appropriate risk assessments are conducted, and controls implemented, for any task requiring the use of a workplace substance.
4.5 Staff and Students

Staff and students must

  • comply with these Procedures and follow all instructions and directions relating to the acquisition, use, handling, storage and disposal of workplace substances;
  • report any inappropriate use of workplace substances to their line manager, supervisor, health & safety representative and/or the OHS Unit;
  • report immediately and incident involving workplace substances to their line manager, supervisor and/or the OHS Unit.



Steps Actions Who is responsible
5.1 Purchasing
  • Implement a system for purchasing and controlled use, including risk assessment prior to use, in the local area so that hazards that cannot be controlled are eliminated at source (eg highly toxic substance not purchased as ventilation in proposed area of use is inadequate).
  • Ensure that for all new workplace substances, the Material Safety Data Sheet (MSDS) is consulted, and risk assessment completed, before the material is used. See Steps 5.3 and 5.6.
  • Where risk assessments with controls in place are rated Extreme or High, purchase of the workplace substance(s) must be referred to the Cost Centre Head for approval of use.
  • Ensure that when the substance enters the workplace it is added to the workplace substances register.
  • If you are importing substances, you must check that the substance is on the National Industrial Chemicals Notification and Assessment Scheme (NICNAS) data base. Any hazardous substance used/stored in Australia must appear on the NICNAS database. The person importing the substance is responsible for checking the database and notifying NICNAS if it is not present.
  • A permit issued by the SA Health Commission is required for all Schedule 2, 3, 4, 5, 6, 7, 8 & 9 substances (as defined in the Controlled Substances Act). Contact the OHS Unit for further information prior to purchase or acquisition of such substances.

    Additional requirements for Controlled Substances (Scheduled Drugs and Poisons) are set out in the Scheduled Drugs & Poisons procedure (Appendix A).

    Additional requirements for Security Sensitive Ammonium Nitrate are set out in Appendix B.
  • On receipt of any substance staff must ensure that all measures are in place to control any identified risks.
Managers/supervisors (eg Head of School, Centre or work area) with the area's Workplace Substances Manager
5.2 Registers

Workplace Substances Register

  • Each local area (eg a laboratory, workshop, store etc) must have an accurate and up-to-date workplace substances register which lists each hazardous substance, dangerous good or controlled substance in use, produced or being stored in that area. The Register must also have an MSDS for each workplace substance.

Where an electronic register is to be compiled the University’s ChemWatch database and information system must be used.  Contact the OHS Unit for access to ChemWatch.
Areas which do not have access to ChemWatch, or where access is not feasible, must maintain, and keep current, a hard copy register.
See Workplace Substances Register template.

  • On the Register, indicate which substances are dangerous goods. Record the dangerous goods class, packaging group and UN number. The MSDS provides all this information.
  • Where Controlled Substances (Poisons & Scheduled Drugs) are stored, produced or in use, you must have a separate Controlled Substances Register recording the quantity of each poison/drug produced, received, used or destroyed.
  • Where Security Sensitive Ammonium Nitrate (SSAN) is stored, produced or in use, you must have a separate SSAN Register recording the quantity of each poison/drug produced, received, used or destroyed.
  • Contractors who are using hazardous substances must keep a copy of their workplace substances register on site in a convenient location. See Flinders University Contractor Safety Policy & Procedures.

Register of Permits

  • Where permits are required for particular types of workplace substances (eg Controlled Substances, explosive materials, etc), the local area must maintain an up-to-date Register of such permits, detailing the permit number, expiry date, staff approved to use the substances concerned.

  • A copy of such permits must be provided to the OHS Unit.

Emergency Services Register

  • Each building must have a separate register which states the quantity, type and location of dangerous goods (including SSAN) located in the building, to enable emergency services to respond appropriately if called to an emergency.

  • Emergency Services registers should be stored in a secure location readily accessible to emergency services and protected from fire or interference (eg EWIS Board)

the contractor(s)/contractors







5.3 Material Safety Data Sheets (MSDS)

An MSDS must be available for each workplace substance purchased, stored or in use. MSDSs must be readily accessible and available in the immediate vicinity at all times. If you are using an electronic system for maintaining MSDSs you must be satisfied that it can cater for this requirement and you must have a back up plan in the event of a computer, server or power failure.

MSDSs must:

  • have information provided in a form that is easily understood by the user
  • identify if the substance is a designated hazardous substance
  • meet the needs of those persons with language or literacy difficulties.

MSDSs are available through ChemWatch, which has a sort facility that enables MSDSs to be printed on coloured paper to indicate the degree of hazard (most hazardous RED - ORANGE -YELLOW - BLUE least hazardous).

Manufacturers/suppliers are required to review and update MSDSs every five years. ChemWatch provides an update service every three months. Hard copies of MSDSs must be re-printed every 5 years.

Contracts for the supply of workplace substances to the University must include provision for the supplier to supply the appropriate MSDS and notify the University of any changes in the formulation of the product.

Supervisor of the area with the area's Workplace Substances Manager
5.4 Labelling

All workplace substances must be labelled in accordance with the Approved Code of Practice for the Labeling of Workplace Substances. This includes substances which are produced either directly or as a by-product within the University.

When a substance is transferred or decanted from a Supplier’s container and not used immediately, the container must be labelled with:

  • the name of the product
  • the appropriate risk phases
  • the appropriate safety phases

Labels suitable for drums, winchesters and small bottles are available through ChemWatch.

Substances classified as Dangerous Goods must meet the requirements of the Dangerous Goods legislation (ie state to which dangerous good class they each belong).

When a substance is not covered by an up-to-date risk assessment for the process in which it is to be used, then it must be labelled prohibited for use and stored appropriately, and not used, until a risk assessment is completed and any risk control measures implemented.

Supervisor of the area with the area’s Workplace Substances Manager
5.5 Labelling of enclosed systems

Workplace Substances contained in an enclosed system (such as a pipe or piping system) must be identified and labelled, with the colour coding system in AS 1319, Safety Signs for the Occupational Environment and labelling AS 1345 Identification of the Contents of Piping, Conduits and Ducts.

Director, Buildings & Property Division
5.6 Hazard identification and Risk Assessment

Hazard identification and risk assessment must be done and recorded for any process (including storage, transport and disposal) using workplace substances prior to the commencement of the process.

See Workplace Substances Checklist and Risk Assessment  

The Guide to Hazard Identification, Risk Assessment, Control and Reviewing details the process of hazard management, including risk assessment.

Risk assessments must also be done on the facility/location used to store the workplace substances eg risk assessment for storage in a chemical store or workshop, or laboratory.

Risk assessments are to be reviewed in the event of a change of process, a change to plant or a substance, new information regarding the hazards or inadequate exposure control being identified and new or improved controls becoming reasonably practicable. As a minimum all risk assessments must be reviewed every 5 years.

Risk assessments must be maintained on a document control register to ensure that people are working from the latest version.

Written by the person(s) involved in the work, and signed off by the supervisor
5.7 Hazard Control Measures

Where a risk assessment has identified that there is a risk to health arising from work with workplace substances, the area concerned must eliminate or minimize the risk by using the Hierarchy of Control risk control measures:

  1. eliminate the hazard
  2. substitute the hazard with something of a lesser risk
  3. isolate the hazard
  4. use engineering controls
  5. use Administrative controls
  6. use personal protective clothing or equipment

You must use the highest possible control option (1. is the highest) and you may need to use more than one control method. When you decide to use a lower level of control you must document the reasons for not using higher levels of control.

Engineering controls must be inspected and maintained. For example, fume cupboards must be inspected every 12 months and placed out of service if they fail the test. The fume cupboard must not be used again until maintained and retested.

Where required, Personal Protective Clothing and Equipment must be communicated, supplied and enforced.
Manager/Supervisor of the area and supervisors
5.8 Storage

Storage quantities should be kept to a minimum to cater for demand, but avoid storage of excess quantities for long periods.

Adequate and secure storage facilities must be provided for all workplace substances. The doors are to be kept locked except when there is a staff member or honours/postgraduate student present who has been assigned the responsibility of accessing this facility. Any substance to be removed from the storage facility is to undergo a simple risk assessment, taking into consideration information regarding the safe use and handling of the substance.

Dangerous Goods must be stored in accordance with the requirements for separation, segregation and signage.. They must be stored in Australian Standard specified cabinets for each type of dangerous goods (depending on the quantity stored).

Controlled Substances must be stored in accordance with the requirements of the University’s Controlled Substances Permit(s). (See Appendix A).

Each area using SSAN must have written protocols to ensure that SSAN is kept in a secure manner and used only for specified research or educational purposes (see also Appendix B).

Manager/Supervisor of the area and Supervisors, with the area’s Workplace Substances Manager
5.9 Safe Work Systems

Each area with workplace substances must implement safe work systems eg:

  • having systems for preventing unauthorized access;
  • providing adequate supervision (commensurate with risk and level of competency of user);
  • arrangements for working after hours;
method of induction of new staff/students; etc
Manager/Supervisor of the area, with the area’s Workplace Substances Manager
5.10 Equipment & Safe Operating Procedures (SOPs)

All equipment used in conjunction with workplace substances must be inspected and maintained in accordance with the manufacturer’s instructions and relevant Australian Standards. See Plant Safety for further information.

Where necessary as indicated by your risk assessments, you must write and communicate SOPs, and maintain them on a document control register.

For equipment which requires an established level of competence to operate, the competence requirements must be documented and an authorisation process established (eg a list of authorised persons who are allowed to decant cryogens). Authorised persons must have demonstrated competence in the task to the supervisor of the area. Access to the equipment must be controlled to prohibit operation by unauthorised persons.

Clear lines of responsibility must be established where there are shared resources eg staff/students from one school requiring access to equipment belonging to another school.

All ‘visiting’ staff/students to the area where the equipment is housed must abide by the local area requirements including being able to demonstrate competency in the operation of the equipment.
Manager/Supervisor of the area, with the area’s Workplace Substances Manager
5.11 Transportation

Hazardous substances and dangerous goods that are to be transported must comply with containment and packaging guidelines laid down in the Australian Code for the Transport of Dangerous Goods by Road & Rail and, where applicable, IATA Regulations this code only applies if Dangerous goods are moved outside of the premises.

Winchesters must be transported around the University in a carrier or foam box.

Manager/Supervisor of the area, with the area’s Workplace Substances Manager
5.12 Disposal

Waste minimization practices are encouraged through purchasing of smaller quantities, using minimum quantities and sharing substances resources where practicable.

All out-of-date substances must be disposed of periodically to reduce the overall hazard potential and minimize inventory tracking and updating.

The most appropriate means of disposal must be determined using information contained in MSDSs and Environmental Protection Authority (EPA) Guidelines.

Substances no longer required must be removed from the workplace by a licensed operator for disposal, as per Environment Protection Authority (EPA) guidelines. http://www.epa.sa.gov.au/. The University uses a licensed contractor to remove hazardous waste from its premises. Contact the University Services Manager for details.

Manager/Supervisor of the area, with the area’s Workplace Substances Manager
5.13 Air Monitoring & Health Surveillance

Air monitoring may be required as part of the risk assessment (where it is necessary to obtain a quantitative estimate of exposure), or to determine the effectiveness of engineering controls.

The South Australian OHS Regulations require the University to provide health surveillance if the risk assessment identifies that there is significant risk to health and staff are exposed to any of the substances listed in Schedule 6 Hazardous Substances for which Health Surveillance is Required of the OHS Regulations.

The Cost Centre is responsible for organising, paying for and keeping the records (for 30 years) of the results of health surveillance. Contact the OHS Unit for further information.
Manager of area, with the area’s Workplace Substances Manager
5.14 Emergency facilities

Emergency facilities must be identified, put in place and monitored. Such facilities include:

  • spill kits
  • fire blankets/extinguishers
  • personal protective equipment & clothing
  • first aid kits
  • eye wash stations/emergency showers
  • contact numbers for trained first aiders
  • emergency shut down procedures for equipment

Areas must develop local emergency procedures in the event of a spill or leak of a workplace substance, fire, explosion or other emergency situation.

See also the University’s Incident Control Policy & Procedures.

Manager of the area, with the area’s Workplace Substances Manager
5.15 Chemical Spills

For minor spills
(ie small enough to be cleaned up without risk to you or others)

  • alert those in the area;
  • wearing appropriate protective equipment/clothing, clean the spill with spill kit;
  • Dispose of material as hazardous waste.

For serious spills

  • Alert those in the area and evacuate, closing doors;
  • Call Emergency Services (Fire) and University Security (they will deal with the emergency services);
  • Inform the chief warden for the building or follow the area’s emergency procedures;
  • Notify the OHS Unit
  • Keep people away from the area.
Manager/Supervisor of the area, with the area’s Workplace Substances Manager
5.16 Taining

All staff and students who work with workplace substances must receive training in workplace substances safety to enable them to work competently and safely in the laboratory/work area.

Once the area has identified the training needs (though a local training needs analysis), the area must establish a system for training their staff and/or students.

The OHS Unit can assist in basic workplace substances awareness training. However the supervisor of the area must provide local training so that staff and/or students are able to work competently and safely in a multi-functional laboratory which may have hazardous substances, biological, radiation, nanotechnology, equipment etc risks.

Records of training must be kept by the local area.
Manager/Supervisor of the area, with the area’s Workplace Substances Manager
5.17 Record Keeping

The following records must be maintained for work with workplace substances:

  • Workplace substances register and MSDSs
  • risk assessments (in a controlled register)
  • Training records
  • Any air monitoring/ health surveillance records
  • SOPs (in a controlled register)
  • Inspection and testing records for engineering controls
  • Emergency procedures (eg local spills procedures),. See 5.14.
Manager/Supervisor of the area, with the area’s Workplace Substances Manager
5.18 Inspections, Audits and Reviews

Each area must have a system for regularly inspecting the workplace to ensure that procedures are being followed and a high level of housekeeping is maintained.

The OHS Unit coordinates and facilitates regular Workplace substances audits within Cost Centres.

Controlled Substances (Scheduled Drugs and Poisons)

The South Australian Controlled Substances Act 1984  recognises that many of the substances controlled by the Act may be needed for teaching students, training staff or for research purposes. The Act allows South Australian Department of Health to issue permits for these purposes. The University is not permitted to manufacture, produce, possess or use Scheduled drugs and poisons without such permits.

1. Permits

1.1 Research Instruction or Training Permit
The University has a Research Instruction or Training Permit which
allows the University to manufacture, produce, possess and use Schedule 2, 3, 4, 5, 6 and 7 substances.

The permit requires the University to comply with the following conditions:

  • The poisons must not be re-sold or supplied to any other person;
  • The University holder shall store these poisons, when not in use, in suitable containers, appropriately labelled, in a locked receptacle or enclosure;
  • The poisons shall not be kept elsewhere than at the premises specified;
  • Access to the poisons shall be restricted to persons under the direction of the University;
  • The poisons shall be used in accordance with guidelines prepared by or under the direction of the University; and
  • A record indicating the quantity of each poison manufactured, produced, received, used or destroyed during the currency of this permit must be kept by the University

Staff using these Substances must comply with these conditions. To breach the conditions of the University’s licence is an unlawful act, which would result in a loss of licence and the University’s ability to purchase and hold these types of substances.

1.2 Permit to Possess
The University also has a Permit to Possess poisons at its Rural Clinical Schools at Renmark and Mt Gambier and at other South Australian Health Services where simulation sessions are being conducted.

The Permit requires the university to comply with the following conditions:

  • The drugs are to be stored in a locked storage facility and are only to be accessible to University staff for the purposes of simulation training;
  • When in transit to external healthcare facilities for training, the drugs are to be locked within the vehicle concealed from sight and not left unattended;
  • A register which shows the amount of substances received, used, discarded or destroyed shall be kept. Such records must be available for inspection by authorised persons; and
  • The substances shall be used for training and instruction purposes only.

1.3 Individual Permits for Schedule 8 & 9 Substances
Schedule 8 & 9 Substances require separate individual licences. Applications for these permits must be approved by the University. Any staff member requiring these Substances for research purposes should contact the University's Research Services Office in the first instance.

Applications for such permits must be made through the relevant Cost Centre Head and require the approval of the Vice-President (Strategic Finance and Resources).

2. Responsibility

The Cost Centre Head in whose Cost Centre the Scheduled Drugs and Poisons are manufactured, produced, possessed or used is responsible for ensuring that the Licence requirements and the University’s Workplace Substances Procedures are implemented and complied with.




Security Sensitive Ammonium Nitrate (SSAN)

The University is exempt from the requirements of the Explosives (Security Sensitive Substances) Regulations 2006 subject to the University complying with the following conditions:

  1. The Executive Officer of each institution notifying in writing to the Manager, Dangerous Substances, SafeWork SA, by 22 December 2006 that the institution holds, either continuously or from time to time, quantities of Security Sensitive Ammonium Nitrate.
  2. All purchase of procurements of Security Sensitive Ammonium Nitrate being recorded in an auditable format.
  3. Each use or disposal of Security Sensitive Ammonium Nitrate being recorded in an auditable format.
  4. Each record being kept for a period of at least five years.
  5. All records being made available to a gazetted Inspector of Explosives on request within 14 days.
  6. Any loss or theft of Security Sensitive Ammonium Nitrate reported immediately to the Manager, Dangerous Substances, SafeWork SA and the South Australian Police Department
  7. Written protocols being introduced by 22 December 2006 to ensure that all quantities of Security Sensitive Ammonium Nitrate are kept in a secure manner and only used for specified research or educational purposes.
  8. No more than 3kg of Security Sensitive Ammonium Nitrate being kept in any laboratory or other area of use at any time.

Any staff member who is intending to use SSAN for research or educational purposes must contact the OHS Unit, prior to purchase of SSAN,  for further information.
