  4. Supporting incident response, investigation and share the lessons learnt across the organisation

Part B - General

(11) Laboratory work will vary widely, presenting differing levels of hazard and risk with consideration to the type of activity undertaken. The following groupings are indicative categories to assist aligning the level of risk assessment, personal protective equipment (PPE) requirements and supervision that is required.

Low Risk Activity

(12) Observational laboratory work or theoretical modelling that is carried out by students for the purpose of teaching and learning and is of low risk to Health and Safety. Examples include health monitoring, electronic circuitry and computer modelling. In these instances, the laboratories used are typically dry facilities.

General Laboratory Activity

(13) Practical activities that are typically associated with laboratories such as wet experimental work using chemical substances and biological materials or dry facilities where specialised equipment is used.

Heightened Risk Activity

(14) Activity which includes hazardous substances, biological models and complex equipment such as lasers that poses heightened risk due to the inherent risk or because the combination that is being utilised. Risk assessments will identify activities which have heightened associated risk. In these instances, Physical Containment (PC) laboratories are frequently utilised as a control measure to address heightened risk.

Part C - Risk Assessment

(15) Each School will undertake risk assessments to identify and address the differing types of laboratory work to ensure simple activities adhere to basic requirements whilst complex undertakings are deeply considered and carefully planned for.

(16) The function of risk assessments is to raise awareness of the hazards and quantify the risk. This process enables a review of the controls in place relative to the risk and promotes the consideration of additional controls to improve hazard management. The residual risk rating will realistically reflect the remaining risk to ensure that the line of sight to the hazard/s is not lost nor diminished.

  1. Risk assessments for all laboratory operations will be completed and periodically reviewed.
  2. Risk assessments will be updated when new materials and/or methods are introduced and standard operating procedures modified as required.
  3. Each completed risk assessment will include supervisor sign off. Where the inherent hazard risk is high, the departmental head will review and sign off on the risk assessment.
  4. Risk assessment documentation will be kept for 10 years at a minimum and longer when legislatively required.

Part D - Laboratory and Simulation Environment Safety Induction

(17) In addition to the general Health & Safety induction that all staff and students complete as part of the onboarding process, a laboratory safety induction will be completed for general laboratory work and include practical skills induction for specific equipment or techniques that will be utilised.

(18) Each school will develop a range of inductions to capture the differing requirements of undergraduate, postgraduate and research requirements relative to the laboratories under their management and the level of risk.

Part E - Personal Protective Equipment (PPE)

(19) The selection of personal protective equipment (PPE) will be guided by the type of laboratory activity under consideration and in consideration of the hazards and risks involved.

(20) As a minimal requirement, all staff and students participating in wet laboratory activity will wear enclosed footwear and a laboratory coat or gown and eye protection.

  1. Personal clothing worn will be suitable for wet laboratory conditions and will provide adequate skin protection.
  2. Laboratory costs or gowns will be fully fastened or tied and sleeves fully extended.
  3. Where activities include the use of mechanised equipment, heat source or naked flame, flowing garments such as headscarves and gowns, constructed from non-flammable material will be tucked in.
  4. Long hair will be tied back.
  5. Eye protection will be worn where identifed through risk assessments and/or safety data sheets and will comply with AS/NZ 1336, 1337 & 1338.
  6. Additional PPE will be used as identified from either a risk assessment, safety data sheet or the laboratory protocol.

Part F - Laboratory Supervision

(21) All laboratory work undertaken for teaching purposes will be supervised by staff. The levels of supervision will be commensurate to the risks as determined by the activity risk assessment.

Part G - Working Alone or Outside Operational Hours

(22) There are occasional circumstances where participants may need to work alone or outside normal operational hours to complete laboratory activity. In these instances the consequential risk of some hazards may increase, as immediate assistance in the event of an incident is reduced.

(23) Where the activity risk assessment identifies that the planned activity has moderate or heightened risk, then the activity will not proceed without the adequate supervision from staff.

(24) The following are examples of activities that will not be undertaken alone or without adequate supervision for the purposes of teaching and learning:

  1. Operating equipment or machinery that is capable of inflicting serious injury
  2. Using apparatus that could result in the release of high energy or significant levels of toxic or environmentally damaging hazardous material
  3. Working with toxic or corrosive substances where there is a significant risk of exposure
  4. Handling venomous biological specimens
  5. Working with large animals, other than feeding or observation
  6. Working with microorganisms of Risk Group 3 or higher or work that requires the use of a Containment level 3 facility
  7. Working with exposed energised or electrical systems
  8. Operating lasers of Class 3 and above
  9. Working with radionuclides that require adherence to the National Radiation Laboratory code
  10. Working in environments, below or above atmospheric pressure and where there is a risk of low oxygen or a toxic atmosphere

Part H - Immunisation

(25) Specific immunisation is essential before commencing laboratory work that involves a heightened risk of infection. The possibility and type of infection should be risk assessed and appropriate controls developed.

(26) It is recommended that all staff and students undertaking wet laboratory work have current immunisation for tetanus. Immunisation can be obtained from the medical clinics at each campus or by contacting the supervisor.

  1. Hepatitis B immunisation is required before commencing any activity with unscreened human blood or fluids
  2. Q fever immunisation is required before commencing any activity with sheep, goats, and cattle or with feral animals
  3. Rabies and/or Lyssa virus immunisation is required before commencing any activity with bats or flying foxes

(27) Where a participant does not complete the required immunisation, this circumstance is documented and signed by the participant to demonstrate knowledge and acceptance of the risks.

Part I - Working With Animals

(28) Participants who will be exposed to animal allergens from the planned activities will follow the guideline for Working with Animals to manage the inherent risk that are associated with the tasks undertaken. Managing this risk may include health monitoring and will be determined through a detailed risk assessment that considers the type of allergen, exposure levels, and the tasks undertaken.

Part J - Health Surveillance

(29) Health surveillance will be instigated and managed when a risk assessment determines this requirement in association with the use of a hazardous substance/s. Base line health surveillance will be established before activity commences and undertaken by the medical clinics that are available or associated with the University at each campus. Monitoring will be managed by the supervisor and records maintained through HR records.

Part K - Disabilities, Medical Restrictions and Pregnancy

(30) Where a participant discloses a disability (including temporary), medical restriction or pregnancy, a risk assessment will be undertaken to identify laboratory activities which may impact the restriction and a plan developed with the assistance of the HSE team. The plan may address the exclusion to tasks or activities where the levels of control cannot adequately manage the risk.
