Guideline review date: 24 September 2025

This guideline is provided to support schools in implementing the managing risks in school curriculum activities procedure.

The CARA planner (DOCX, 232KB) must be used for the specific school context in conjunction with this guideline considering additional risks, hazards and controls and including environmental, facility, equipment and student considerations.

For activities beyond the scope of this guideline, complete a CARA record using the CARA generic template (DOCX, 98KB).

Activity scope

This guideline demonstrates the minimum safety standard for student participation in biological activities (e.g. studying animal tissues, live specimens, invertebrate organisms, microorganisms, plant material, fungi or tasting food samples grown in the school garden) to support curriculum delivery within, and external to, a science laboratory. This activity may also involve the use of a range of laboratory equipment (e.g. glassware, heating and digital equipment and chemicals).

The Department of Education is committed to ensuring that curriculum activities are planned for and managed in accordance with the Work Health and Safety Act 2011 (Qld), to ensure, as far as is reasonably practicable, the safety of students, staff and others.

Depending on the scope of this activity, other risk assessments may be required when planning. Curriculum activities encompassing more than 1 CARA guideline (e.g. marine organism activities when conducting fieldwork to investigate microorganisms) must comply with the requirements of all CARA guidelines appropriate to the activity.

For curriculum activities involving the introduction of agents or conditions that may contaminate food, consult the food experimentation activity guideline.

For curriculum activities involving observing and handling animals and animal remains, consult the animal observation and handling activity guideline.

For curriculum activities involving observing and handling marine animals and organisms, consult the marine organism activities activity guideline.

For activities conducted at a non-Department of Education venue, and/or when engaging external expertise, request written risk assessment advice and attach it to this CARA record.

For activities conducted off-site, schools must comply with the school excursions procedure.

Low risk
Activities involving low risk equipment and non-hazardous biological material (e.g. pre-prepared microscope slides, pond water, silkworms, foodstuffs).

Medium risk
Activities involving medium risk equipment and hazardous substances (e.g. handling and dissecting animals procured as laboratory specimens, growing cultures under controlled circumstances according to established protocols).

High risk
Activities involving high risk equipment and materials (e.g. using unknown samples such as swabs from environmental samples, high levels of heat, very low temperature materials, high pressures or low, full vacuums, high-voltage electricity [static and/or current], radiation emitters, hazardous biological materials and high-speed mechanical and/or moving devices and objects).

Extreme risk
Activities involving extreme risk processes and materials (e.g. growing cultures in uncontrolled environments, handling and/or dissecting animals not procured as a laboratory specimen).

Activity requirements

If any requirement cannot be met, the activity must not occur.

A registered teacher must be appointed to maintain overall responsibility for the activity.

Teachers, in collaboration with other adult supervisors of the planned activity, determine additional risks, hazards and control measures relevant to the activity and the specific school/group circumstances in order to lift the safety standard above the minimum identified in the CARA guideline. Consult review comments from previous CARA records to improve safety standards based on the advice from the previous supervisors of the activity at the school.

Prior consultation and collaboration with local expertise (e.g. lab manager) is required for local advice, emergency support mechanisms and additional supervision requirements to ensure participant and public safety.

The following activities are prohibited:

taking human blood samples or using human blood products
collecting samples from areas likely to pose risk of contamination by human pathogens including, but not limited to, human or animal body fluids, waste on toilets, carcasses, diseased tissue (plant or animal), hand basins, door handles, phones or computer keyboards
swabbing raw poultry or surfaces used to prepare raw poultry
sub-culturing swabs taken from food preparation surfaces
incubating body fluids or other tissues in broths, plates or cultures
incubating microbial cultures at temperatures higher than 30ºC.

Schools may sample human saliva, urine, cheek cell and/or DNA, however, students must only collect/handle their own samples.

All biological material is to be considered contaminated and potentially hazardous.

Schools must prevent and manage infection control in accordance with the infection control procedure and/or relevant Australian Standards (e.g. AS 2243.3—Safety in laboratories: Microbiological safety and containment). Utilise the infection control guideline for practical implementation advice.

Unfamiliar activities (e.g. from online sources) must be trialled without students to identify foreseeable hazards and plan safety processes. Do not proceed if risks of the activity outweigh educational outcomes.

Attach any additional information used to support safety in the activity to the CARA record (e.g. resources from Australian Science Teachers Association, published experiments or online risk assessment tools).

Students

Schools must consider age, maturity and skill level of students when planning curriculum activities.

Adjustments are required for students with disability to support access and participation in the curriculum. Consult with the parents/carers of students with disability or, when appropriate, the student to ensure risks related to their child's participation in the activity are identified and managed.

Schools must consult current student medical information and/or health plans in accordance with the managing students' health support needs at school procedure. Record information about any student condition (e.g. physical or medical, such as epilepsy) that may inhibit safe engagement in the activity and include specific support measures within emergency procedures.

For activities with students with a medical condition or disability that may impact on safety during the activity, consultation with parents is required prior to allocating supervision to determine the impact of students' medical condition or disability on safety during the activity.

For participants with known allergies, schools must comply with the supporting students with asthma and/or at risk of anaphylaxis at school procedure and the school's anaphylaxis risk management plan (DOCX, 159KB), including an adult supervisor of the activity with anaphylaxis training.

Emergency and first-aid

Induction and instruction

Consent

Supervision

Principals, in consultation with the qualified adults, make final supervision decisions* for the activity that considers the local context.

Appropriate adult supervision must be provided to manage the activity safely (i.e. prevent an incident from occurring and manage an incident if one were to occur, including managing emergency situations). The principal must give active consideration to the minimum standards set in the CARA guideline for the activity, the CARA planner and the risk assessment when determining the appropriate level of supervision.

See number of adult supervisors below.

Participants must adhere to all rules and advice communicated by the facility operator/owner and any safety signage at the facility/location.

Before the activity, all adult supervisors:

must be familiar with the contents of the CARA record, including the emergency and supervision plans.

During the activity, all adult supervisors:

must provide active and direct supervision—be constantly vigilant, attentive and rescue ready
must comply with control measures from the CARA record and adapt as hazards arise
must not rely on students to recover a person in difficulty at any time
must suspend the activity if the conditions become unfavourable (e.g. extreme temperatures).

The activity must be suspended if the conditions become unfavourable (e.g. uncontrollable hazards arising).

Do not allow experiment products from the laboratory (e.g. reactant products, food products to be removed by students or taken home).

For high risk activities:

closely supervise students during participation. It is recommended that teacher demonstration be used as the principal teaching strategy for high risk activities, with students remaining at a safe distance.

For extreme risk activities:

individually supervise students during participation. It is recommended that teacher demonstration be used as the principal teaching strategy for extreme risk activities, with students remaining at a safe distance.

Number of adult supervisors

Principals, in consultation with the qualified adults of the activity, determine the final number of supervisors to fulfil instructional, emergency and supervision roles for the local context that consider the nature of the activity, students' ages, abilities and specialised learning, access and/or health needs. In some instances, the final supervision ratio may be 1:1.

If the minimum safety standard cannot be met, modify the activity (or elements of it) and use the hierarchy of controls to implement alternative control measures to meet or exceed the minimum safety standard (e.g. reduce the number of students participating at any one time).

See frequently asked questions (FAQs) for further support.

Supervisor qualifications

Qualifications support the minimum safety standard for this activity. Principals make final decisions* in determining supervisor capability (competence, relevance and currency) and whether the activity leader meets an appropriate teaching standard.

*See FAQs for further support.

Facilities and equipment

The qualified adult supervisor of the activity, in consultation with the principal, determines the requirements for facilities and equipment appropriate to the local context.

Consult chemicals in curriculum activities for support in assessing the risks of chemicals used with/by students in curriculum activities.

If a CARA record is required in OneSchool, a summary of chemicals, plant, equipment and/or materials used in the activity must be provided by entering directly onto the CARA record in OneSchool or by attaching a summary. Sample templates are provided on chemicals in curriculum activities and plant, equipment and materials in curriculum activities.

Location must be suitable for the activity being undertaken, including sufficient space, adequate lighting and ventilation to ensure safe participation and that safety rules and procedures can be followed. This may be in a specialised facility (e.g. laboratory) or other suitable location (e.g. school stockyard). Undertake a reconnaissance of new or infrequently used locations to ascertain suitability.

All emergency equipment and processes (e.g. shut-off switches, eye wash unit) must be functional.

Schools must source biological specimens (e.g. animals bred for scientific purposes) from commercial suppliers.

Schools must maintain, store, transport and dispose of biological material appropriately, for example, use safety data sheet (SDS) and clinical and related waste guideline (PDF, 760KB). Such materials include, but are not limited to, live animals (e.g. silkworms, fish), biological material (e.g. specimens, manure, foodstuffs), wastes (e.g. paper towel, gloves) and used instruments (e.g. dissection boards, probes). Comply with animals in Queensland state schools requirements when handling live animals.

Participants must wear personal protective equipment including non-porous enclosed footwear and apron/coat. Other personal protective equipment appropriate to the activity may include lab standard eye protection, gloves, appropriate face protection (e.g. mask to protect against airborne organisms in potting mix).

First aid equipment and consumables, as required.

Equipment and tools must be well-maintained, transported safely (e.g. using a protective cover) and stored appropriately. Conduct a visual inspection of equipment (including portable electrical equipment) to identify damage and remove from use.

Clean up equipment as necessary (e.g. dustpan, breakages bin, spill kit, disinfectants for microorganisms).

In addition to the above, for high or extreme risk level activities:

activities must take place in a laboratory with accessible and functional safety features, for example, appropriate physical containment conditions and safety precautions per Australian Standards (AS2243.3)
all high and extreme risk biological resources and equipment must be clearly labelled according to the safe operating procedure (SOP) or SDS requirements from the supplier.

Common hazards and controls

Further to those listed, include any additional hazards and control measures considering the local context of the activity.

Environmental hazards	Control measures
Animal bites/stings	If participating outside: respond appropriately to approaching wildlife use insect repellent, as outlined in insect viruses and allergies
Biological material	Avoid contact with plant and animal material (e.g. saps, tissue matter). Include protection and handling processes with student safety procedures (e.g. rinsing equipment after use). Use only the smallest quantity of biological material that will guarantee the viability of the experiment. If swabs are taken from food preparation surfaces, keep petri dishes closed to reduce the risk of transmission of foodborne illness (e.g. Salmonella and E.coli). Wash hands and other contaminated areas of the body with soap and water before leaving the activity site. Sterilise biological material (e.g. microbial, genetic, enzymatic) and tools appropriately before disposal. Note: If unsure, seek advice from an institution proficient in disposal techniques, such as a university. Clean tools following use to reduce the risk of contamination or accidental exposure. Sterilise equipment in contact with microbial and genetically modified organisms. Dispose of hazardous biological materials using a double-bagging technique. Label and date all specimens and samples for storage. Refrigerate as necessary. Dispose within appropriate timeframes
Environmental conditions	Assess weather conditions prior to undertaking the activity, inspecting the intended location in order to identify variable risks, hazards and potential dangers. Follow the school's sun safety policy, including appropriate clothing, sun protection (e.g. sunscreen) and shade facilities when outside. Follow the managing excessive heat in schools guidelines when participating in very hot or extreme heat conditions. Ensure drink breaks occur regularly. Make water available for individual participants between drink breaks. Monitor participants for cold related illness (e.g. hypothermia) in cold weather conditions
Facilities and equipment hazards	Control measures
Electricity	Electrical or extension leads must not pose a tripping hazard. Secure (e.g. tape down) and cover for protection. Consider the placement of technology devices (e.g. tablets, laptops) and the peripherals (e.g. cords, mouse) during activities to avoid contamination by chemical/biological materials or contact with water
Faulty or dangerous equipment	Check equipment for damage before and during the activity. Comply with control measures provided on the SOP or manufacturer's instructions. See the plant, equipment and materials in curriculum activities template for details of specific risk management practices. Restrict student access to any equipment that requires thermal insulation (e.g. liquid nitrogen, incubator)
Hazardous chemicals	Comply with control measures for preparation, use and disposal of chemicals provided on the vendor SDS in the school Chemwatch manifest and/or safety instructions on the product label. See the chemicals in curriculum activities template for details of specific risk management practices for each Chemwatch hazard colour rating. All chemicals required for the decontamination processes must be arranged in advance and be readily available. Manage spills immediately
Heat sources and radiation	Only appropriately-qualified adult supervisors may handle radiation sources and equipment (e.g. UV lamps). Establish and implement an exclusion zone away from equipment that may produce radiation. Clearly sign/label equipment with hot surfaces and allow to cool before being returned to storage. Manage heat sources and/or combustible substances safely. This includes, but is not limited to: keeping burners on low heat or orange flame while not directly in use, using small quantities of combustible substances only, keeping combustible or toxic substances away from naked flames and using appropriate water-bath techniques
Waste	Dispose of waste according to established safety procedure as soon as possible after the activity
Student considerations	Control measures
Manual handing	Use correct manual handling processes when lifting, lowering, pushing, pulling or carrying. Use aids for safe handling, lifting and carrying (e.g. guards, safety steps and mobile trolleys), as appropriate
Student issues	Where individual experimental investigations are undertaken, students must have complete and appropriate procedures in place that identify and manage hazards associated with their activity. Remove accessories (e.g. necklaces, lanyards) before participating. Ensure fingernails and hair and clothing (e.g. long hair, loose shirts) do not interfere with the activity. Monitor and enforce the correct use of equipment and materials and safe movement around the area. Account for all equipment, chemicals and resources (e.g. matches, unused samples) after the activity. In addition, for off-site activities: implement procedures (e.g. buddy system, roll marking mechanisms) to account for all participants before, during and after the activity ensure staff can easily recognise those students with health support needs and are familiar with their needs when participating off-site
