An approved code of practice is a practical guide to achieving the standards of health, safety
and welfare required under the WHS Act and the Work Health and Safety Regulations (the
WHS Regulations).
A code of practice applies to anyone who has a duty of care in the circumstances described
in the code. In most cases, following an approved code of practice would achieve compliance
with the health and safety duties in the WHS Act, in relation to the subject matter of the code.
Like regulations, codes of practice deal with particular issues and do not cover all hazards or risks that may arise. The health and safety duties require duty holders to consider all risks associated with work, not only those for which regulations and codes of practice exist.
Codes of practice are admissible in court proceedings under the WHS Act and Regulations.
Courts may regard a code of practice as evidence of what is known about a hazard, risk or control and may rely on the code in determining what is reasonably practicable in the circumstances to which the code relates.
Compliance with the WHS Act and Regulations may be achieved by following another method, such as a technical or an industry standard, if it provides an equivalent or higher standard of work health and safety than the code.
An inspector may refer to an approved code of practice when issuing an improvement or prohibition notice.
This Code of Practice has been developed by Safe Work Australia as a model code of practice under the Council of Australian Governments’ Inter-Governmental Agreement for Regulatory
and Operational Reform in Occupational Health and Safety for adoption by the Commonwealth, state and territory governments.
This Code of Practice provides practical guidance for persons conducting a business or undertaking on how to comply with duties under the WHS Act and Regulations to provide adequate first aid facilities in the workplace. It includes information on first aid kits, procedures, facilities and training for first aiders.
This Code applies to all types of work and all workplaces covered by the WHS Act, including workplaces that are outdoors, mobile or remote.
In providing guidance, the word ‘should’ is used in this Code to indicate a recommended course
of action, while ‘may’ is used to indicate an optional course of action.
This Code also includes various references to provisions of the WHS Act and Regulations which set out the legal requirements. These references are not exhaustive. The words ‘must’, ‘requires’ or ‘mandatory’ indicate that a legal requirement exists and must be complied with.
Providing immediate and effective first aid to workers or others who have been injured or become ill at the workplace may reduce the severity of the injury or illness and promote recovery. In some cases it could mean the difference between life and death.
First aid is the immediate treatment or care given to a person suffering from an injury or illness until more advanced care is provided or the person recovers.
First aider is a person who has successfully completed a nationally accredited training course or an equivalent level of training that has given them the competencies required to administer first aid.
First aid equipment includes first aid kits and other equipment used to treat injuries and illnesses.
First aid facilities include first aid rooms, health centres, clean water supplies and other facilities needed for administering first aid.
High risk workplace means a workplace where workers are exposed to hazards that could result in serious injury or illness and would require first aid. Examples of workplaces that may be considered high risk are ones in which workers:
Low risk workplace means a workplace where workers are not exposed to hazards that could result in serious injury or illness such as offices, shops or libraries. Potential work-related injuries and illnesses requiring first aid would be minor in nature.
A person conducting a business or undertaking has the primary duty under the WHS Act to ensure, so far as is reasonably practicable, that workers and other persons are not exposed to health and safety risks arising from the business or undertaking.
The WHS Regulations place specific obligations on a person conducting a business or undertaking in relation to first aid, including requirements to:
A person conducting a business or undertaking may not need to provide first aid equipment or facilities if these are already provided by another duty holder at the workplace and they are adequate and easily accessible at the times that the workers carry out work.
Officers, such as company directors, have a duty to exercise due diligence to ensure that the business or undertaking complies with the WHS Act and Regulations. This includes taking reasonable steps to ensure that the business or undertaking has and uses appropriate
resources and processes to eliminate or minimise risks to health and safety.
Workers have a duty to take reasonable care for their own health and safety and must not adversely affect the health and safety of other persons. Workers must comply with any reasonable instruction and cooperate with any reasonable policy or procedure relating to health and safety
at the workplace, such as procedures for first aid and for reporting injuries and illnesses.
First aid requirements will vary from one workplace to the next, depending on the nature of the work, the type of hazards, the workplace size and location, as well as the number of people at the workplace. These factors must be taken into account when deciding what first aid arrangements need to be provided.
This Code provides information on using a risk management approach to tailor first aid that suits the circumstances of your workplace, while also providing guidance on the number of first aid kits, their contents and the number of trained first aiders that are appropriate for some types of workplaces.
The risk management approach involves the following four steps (summarised in Appendix A):
Guidance on the general risk management process is available in the Code of Practice:
How to manage work health and safety risks.
Consultation involves sharing of information, giving workers a reasonable opportunity to express views and taking those views into account before making decisions on health and safety matters.
Section 47: A person conducting a business or undertaking must consult, so far as is reasonably practicable, with workers who carry out work for the business or undertaking
who are (or likely to be) directly affected by a work health and safety matter.
Section 48: If the workers are represented by a health and safety representative, the consultation must involve that representative.
You must consult your workers when making decisions about what facilities are needed, including those required for administering first aid. Consultation should include:
Section 46: A person conducting a business or undertaking must consult, co-operate and
co-ordinate activities with all other persons who have a work health or safety duty in relation
to the same matter, so far as is reasonably practicable.
Sometimes you may have responsibility for health and safety together with other business operators who are involved in the same activities or who share the same workplace. In these situations, you should communicate with each other to find out who is doing what and work together in a co-operative and co-ordinated way so that all risks are eliminated or minimised
so far as is reasonably practicable.
For example, if you provide labour hire workers as part of your business you have a duty of care as well as the host business. In these situations, you must discuss the hazards and risks associated with the work and ensure the host business has appropriate first aid arrangements that your workers can access.
If you share your workplace with other businesses that have workers trained in administering first aid, you may be able to ensure that your workers have access to them instead of training your own workers. In these circumstances, it will be necessary to:
Further guidance on consultation is available in the Code of Practice: Work health and safety consultation, co-operation and co-ordination.
Regulation 42: When considering how to provide first aid, a person conducting a business or undertaking must consider all relevant matters including:
Certain work environments have greater risks of injury and illness due to the nature of work being carried out and the nature of the hazards at the workplace. For example, factories, motor vehicle workshops and forestry operations have a greater risk of injury that would require immediate medical treatment than offices or libraries. These workplaces will therefore require different first aid arrangements.
Table 1: Injuries associated with common workplace hazards that may require first aid
Hazard | Potential harm |
Manual tasks | Overexertion can cause muscular strain. |
Working at height | Slips, trips and falls can cause fractures, bruises, lacerations, dislocations, concussion. |
Electricity | Potential ignition source could cause injuries from fire. Exposure to live electrical wires can cause shock, burns and cardiac arrest. |
Machinery and equipment | Being hit by moving vehicles, or being caught by moving parts of machinery can cause fractures, amputation, bruises, lacerations, dislocations. |
Hazardous chemicals | Toxic or corrosive chemicals may be inhaled, contact skin or eyes causing poisoning, chemical burns, irritation. Flammable chemicals could result in injuries from fire or explosion. |
Extreme temperatures | Hot surfaces and materials can cause burns. Exposure to heat can cause heat stress and fatigue. Exposure to extreme cold can cause hypothermia and frost bite. |
Radiation | Welding arc flashes, ionizing radiation and lasers can cause burns |
Violence | Behaviours including intimidation and physical assault can cause nausea, shock and physical injuries |
Biological | Infection, allergic reactions |
Animals | Bites, stings, kicks, scratches |
Records of injuries, illnesses, ‘near miss’ incidents and other information that has already been obtained to assist in controlling risks at the workplace will be useful to make appropriate decisions about first aid.
You should check the safety data sheets (SDS) for any hazardous chemicals that are handled, used or stored at your workplace. The SDS provides information about the chemical, possible health effects, controls that may be used to reduce exposure and first aid requirements.
Manufacturers, importers and suppliers of hazardous chemicals have a duty under the WHS Regulations to ensure that the current SDS is provided to a person at the workplace if the person asks for it.
In relation to the size and location of the workplace, you should take into account:
First aid equipment and facilities should be located at convenient points and in areas where there is a higher risk of an injury or illness occurring.
A large workplace may require first aid to be available in more than one location if:
Where there are separate work areas (for example, a number of buildings on a site or multiple floors in an office building), it may be appropriate to locate first aid facilities centrally and provide first aid kits in each work area. This may include portable first aid kits in motor vehicles and other separate work areas.
The distance of the workplace from ambulance services, hospital and medical centres should be taken into account when determining your first aid requirements. For example, if life-threatening injuries or illnesses could occur and timely access to emergency services cannot be assured,
a person trained in more advanced first aid techniques (such as the provision of oxygen) will
be needed.
Additional first aid considerations may be necessary for workers in remote or isolated areas.
For example, where access is difficult due to poor roads or weather conditions, arrangements
may need to include aerial evacuation.
In minimising the risks to health and safety associated with remote or isolated work, you must provide a system of work that includes effective communication with the worker. This will assist in enabling an immediate response in an emergency. Further guidance about working in remote or isolated areas is available in the Code of Practice: Managing the work environment and facilities.
When considering the size of your workforce, you should include any contractors, subcontractors, and volunteers you engage. This may mean the size of your workforce may vary over time. For the purposes of deciding who requires access to first aid, you should consider the maximum number
of workers that you may engage at any one time. Generally, a larger workforce requires more first aid resources.
You should also consider:
Appendix B provides an example of how to determine first aid requirement
The information provided in this chapter may be used as a guide to determine the appropriate first aid equipment, facilities, first aiders and procedures needed in various workplaces.
First aid equipment, facilities and first aiders must be accessible to workers whenever they work, including those working night shifts or overtime.
All workers must be able to access a first aid kit. This will require at least one first aid kit to be provided at their workplace.
The first aid kit should provide basic equipment for administering first aid for injuries including:
The contents of first aid kits should be based on a risk assessment. For example, there may
be higher risk of eye injuries and a need for additional eye pads in a workplace where:
Additional equipment may be needed for serious burns and remote workplaces.
The recommended content of a typical first aid kit and information on additional equipment
is provided in Appendix C.
First aid kits can be any size, shape or type to suit your workplace, but each kit should:
In the event of a serious injury or illness, quick access to the kit is vital. First aid kits should be kept in a prominent, accessible location and able to be retrieved promptly. Access should also be ensured in security-controlled workplaces. First aid kits should be located close to areas where there is a higher risk of injury or illness. For example, a school with a science laboratory or carpentry workshop should have first aid kits located in these areas. If the workplace occupies several floors in a multi-storey building, at least one kit should be located on every second floor. Emergency floor plans displayed in the workplace should include the location of first aid kits.
A portable first aid kit should be provided in the vehicles of mobile workers if that is their workplace (for example, couriers, taxi drivers, sales representatives, bus drivers and inspectors). These kits should be safely located so as not to become a projectile in the event of an accident.
A person in the workplace should be nominated to maintain the first aid kit (usually a first aider) and should:
Displaying well-recognised, standardised first aid signs will assist in easily locating first aid equipment and facilities. Further information on the design and use of signs is available in AS 1319: – Safety Signs for the Occupational Environment.
In addition to first aid kits, you should consider whether any other first aid equipment is necessary to treat the injuries or illnesses that could occur as a result of a hazard at your workplace.
Providing an automated external defibrillator can reduce the risk of fatality from cardiac arrest. It is a useful addition for workplaces where there is a risk of electrocution or where there are large numbers of members of the public.
Automated external defibrillators are designed to be used by trained or untrained persons.
They should be located in an area that is clearly visible, accessible and not exposed to extreme temperatures. They should be clearly signed and maintained according to the manufacturer’s specifications.
Eye wash and shower equipment may be permanently fixed or portable, depending on the workplace. Eye wash equipment should be provided where there is a risk of hazardous chemicals or infectious substances causing eye injuries.
Immediate access should be provided to shower equipment in workplaces where there is a risk of:
Shower facilities can consist of:
Portable, self-contained eye wash or shower units have their own flushing fluid which needs to be refilled or replaced after use. Further guidance is available in AS 4775 – Emergency eyewash and shower equipment.
A risk assessment will help determine the type of first aid facilities needed. For example, a clean, quiet area within the workplace that affords privacy to an injured or ill person may be suitable and practicable for some workplaces.
Access to a telephone for contacting emergency services or an emergency call system should be provided as part of all first aid facilities.
A first aid room should be established at the workplace if a risk assessment indicates that it would be difficult to administer appropriate first aid unless a first aid room is provided.
For example, workers who carry out work at workplaces where there is a higher risk of serious injury or illness occurring that would not only require immediate first aid, but also further treatment by an emergency service, may benefit from having access to a dedicated first aid room.
A first aid room is recommended for:
The contents of a first aid room should suit the hazards that are specific to the workplace.
The location and size of the room should allow easy access and movement of injured people
who may need to be supported or moved by stretcher or wheelchair.
The following items should be provided in the room:
A first aid room should:
Maintaining a first aid room should be allocated to a trained occupational first aider, except where this room is part of a health centre or hospital.
Health centres staffed by a registered health practitioner (a doctor or nurse) or paramedic can provide emergency medical treatment and cater to the types of hazards in high risk workplaces.
A health centre may be established in the workplace (e.g. at a large mine site) or, if readily available, external emergency services may be used.
If a health centre is located at the workplace, the facility should:
Regulation 42: A person conducting a business or undertaking must ensure that an adequate number of workers are trained to administer first aid at the workplace or that workers have access to an adequate number of other people who have been trained to administer first aid.
First aid in the workplace can be provided in a number of ways:
First aiders should hold nationally recognised Statement/s of Attainment issued by a Registered Training Organisation (RTO) for the nationally endorsed first aid unit/s of competency.
Provide First Aid – provides competencies required to recognise and respond to common life-threatening injuries or illnesses, including life-support using cardiopulmonary resuscitation (CPR), and to manage the casualty and incident until the arrival of medical or other assistance.
In low risk workplaces, first aiders are sufficiently trained if they can perform CPR and treat minor illnesses and injuries.
Provide Advanced First Aid and Provide Advanced First Aid Response – provides additional competencies required to apply advanced first aid procedures. This type of training is suitable for some high risk workplaces.
Manage First Aid Services and Resources – provides competencies required to apply advanced first aid procedures and to manage a first aid room.
Provide First Aid in Remote Situations – provides the competencies required to administer first aid in a remote and/or isolated situation, including preparing for aero-medical evacuation. This type
of training is suitable for high risk workplaces that are likely to have a major delay in accessing emergency services.
First aiders should attend training on a regular basis to refresh their first aid knowledge and
skills and to confirm their competence to provide first aid. Refresher training in CPR should
be undertaken annually and first aid qualifications should be renewed every three years.
First aiders may also need to undertake additional first aid training to respond to specific situations at their workplace. For example, where workers have severe allergies, first aiders should be trained to respond to anaphylaxis if this topic has not been covered in previous first aid training.
The following ratios are recommended:
The number and type of trained first aiders can be further refined by following the five-step guide below:
Step 1:
Identify the maximum number of workers at the workplace at any one time.
Step 2:
Consider the nature of the work being carried out at the workplace and determine if your workers are at a high risk of being exposed to hazards that could require immediate first aid treatment.
Step 3:
Determine if the workplace is remote or if access to emergency services is difficult. High risk workplaces that do not have timely access to medical and ambulance services should have at least one first aider for every 10 workers.
Step 4:
Consider the variety of ways that your workers carry out work, for example:
In these situations, it may not be practicable to have a first aider available at all times at the workplace. However, these workers must be able to access first aid assistance, for example by ensuring they are provided with:
Step 5:
Before finalising the number of first aiders your workers require access to, consider if there are any other factors that indicate that your workplace needs additional first aiders, for example:
You should develop and implement first aid procedures to ensure that workers have a clear understanding of first aid in their workplace. The procedure should cover:
A record of any first aid treatment given should be kept by the first aider and reported to managers on a regular basis to assist reviewing first aid arrangements. First aid treatment records are subject to requirements under Health Records legislation.
Regulation 43: A person conducting a business or undertaking must ensure that an emergency plan is prepared for the workplace that provides procedures to respond effectively in an emergency.
The emergency procedures must include:
You may incorporate your first aid procedures into your emergency planning procedures.
Emergency procedures should specify the role of first aiders according to their level of qualification and competence. In particular, first aiders should be instructed not to exceed their training and expertise in first aid. Other staff, including supervisors, should be instructed not to direct first aiders to exceed their first aid training and expertise.
Further guidance on emergency plans and preparing emergency procedures is available in the Code of Practice: Managing the work environment and facilities.
You must provide information about first aid to your workers so that they know what to do and who to contact if they are sick or injured.
Information should be easy to understand, accessible and should take into account the language and literacy levels of your workers. Information may be given using verbal methods (for example, explanations and demonstrations) or visual methods (for example, videos and posters).
The information and instruction on first aid should include:
The information and instruction should be provided as part of workers’ induction training and when there are any changes, for example in the location of first aid facilities or in the names, locations or contact details of first aiders.
You should regularly review your first aid arrangements in consultation with your workers to ensure they remain adequate and effective.

Medication, including analgesics such as paracetamol and aspirin, should not be included in
first aid kits because of their potential to cause adverse health effects in some people including asthmatics, pregnant women and people with medical conditions. The supply of these medications may also be controlled by drugs and poisons laws. Workers requiring prescribed and over-the-counter medications should carry their own medication for their personal use as necessary.
Some types of workplaces may require additional items to treat specific types of injuries or illnesses.
If work is performed outside and there is a risk of insect or plant stings or snake bites, assess whether the following items should also be included in the first aid kit:
Where people work in remote locations, a first aid kit should include:
The appropriate contents will vary according to the nature of the work and its associated risks.
If your workers are at risk of receiving burns, you should include the following items:
First aiders should take standard precautions to avoid becoming ill and exposing others to illness when handling blood or body substances. Standard precautions are work practices that are applied to all patients and their blood and body substances, regardless of their infectious status, to ensure a basic level of infection prevention and control. Standard precautions include hand hygiene, use of personal protective equipment, appropriate handling and disposal of sharps and waste, cleaning techniques and managing spills of blood and body substances.
Before providing first aid to an injured or ill person, first aiders should assume they could be exposed to infection. First aiders should wash their hands with soap and water or apply alcohol-based hand rub before and after administering first aid. First aiders should also wear personal protective equipment to prevent contact with blood and body substances, including disposable gloves. Eye protection, a mask and protective clothing may also be necessary if splashes of
blood or body substances are likely to occur.
You should establish procedures to avoid workers becoming ill and exposing others to illness
when handling blood or body substances. Procedures could include:
First aiders should be aware of what to do if they have accidental contact with blood or body substances, a sharps injury or contact with a person known to have a contagious illness.
Any part of the body that comes in contact with blood or body substances should be washed
with soap and water immediately. Prompt medical advice should be obtained.
All first aiders should be offered hepatitis B virus vaccination.
All items that are soiled with blood or body substances should be placed in plastic bags and tied securely. Waste disposal should comply with any state or local government requirements.
Sharps, including scissors and tweezers, that have become contaminated with blood or body substances should be disposed of in a rigid-walled, puncture-resistant sharps container by the person that used them. Guidance on the design, construction, colour and markings of sharps containers is provided in:
If a first aider sustains a sharps injury or thinks they are at risk of infection from blood or bodily
fluid contamination, they should seek prompt medical advice.
Cleaning should commence as soon as possible after an incident involving blood or body substances has occurred. First aiders should wear disposable gloves when cleaning spills and
if splashes of blood or body substances may occur, additional protective equipment such as eye protection, plastic aprons and masks should be worn. Surfaces that have been contaminated with blood or body substances should be wiped with paper towelling and cleaned with warm soapy water. It is generally unnecessary to use sodium hypochlorite (chlorine bleach) for managing
spills but it may be used in specific circumstances, for example if the surface is hard to clean.
