Construction is one of Australia’s most hazardous industries. According to Safe Work Australia’s 2025 Key Health and Safety Statistics, the construction sector recorded a serious injury frequency rate of 9.3 claims per million hours worked significantly above the national average of 6.8. Falls from height, crush injuries, lacerations from power tools, electrical incidents, and burns are all real and regular risks on Australian construction sites.
Under Australian WHS legislation, construction is explicitly classified as a high-risk workplace. This classification triggers more stringent first aid obligations than those that apply to offices or retail businesses covering kit contents, first aider ratios, qualification requirements, and site equipment.
Legal Framework for Construction Site First Aid
Construction site first aid obligations are governed by:
- Work Health and Safety Act 2011 (Commonwealth and state equivalents)
- WHS Regulations Section 42 (NSW), equivalent in all other states and territories
- Safe Work Australia Model Code of Practice: First Aid in the Workplace
- Safe Work Australia Code of Practice: Construction Work (which references first aid requirements for construction-specific risks)
The principal contractor on a construction project bears primary responsibility for ensuring first aid provisions are in place across the entire site. Subcontractors also have their own duty of care obligations to their workers.
| Critical Requirement: On high-risk construction sites, first aid must be available at all times during work hours. This includes early starts, late finishes, weekend work, and any period when workers are on site regardless of the number of people present. |
First Aider Ratios for Construction Sites
Construction sites fall into the high-risk category, which means:
| Number of Workers on Site | Minimum First Aiders Required | Qualification Level |
|---|---|---|
| Up to 25 workers | 1 first aider | HLTAID011 |
| 26 – 50 workers | 2 first aiders | HLTAID011 |
| 51 – 100 workers | 4 first aiders | HLTAID011 (at least 1 x HLTAID014 recommended) |
| 100+ workers | 1 per 25 workers at all times | HLTAID014 for site first aid officer |
| Remote or isolated sites | Increased ratios; enhanced kit; emergency comms plan | HLTAID014 strongly recommended |
CPR qualifications (HLTAID009) must be refreshed annually for all construction first aiders, regardless of their broader first aid certificate validity.
Construction Site First Aid Kit Contents
A construction site first aid kit must go significantly beyond what a standard office kit provides. The following items are required to address the specific injury types common to construction environments:
Wound Care
- Adhesive dressings and plasters (large and small sizes, at least 30 total)
- Large combine / trauma wound dressings (at least 6)
- Non-adhesive wound pads (at least 6)
- Sterile gauze swabs (at least 20)
- Wound closure strips (at least 10)
- Heavy-duty scissors (able to cut through work clothing and PPE)
Bleeding Control
- Conforming bandages 5 cm, 7.5 cm, and 10 cm (at least 3 of each)
- Pressure bandages / haemostatic dressings for major bleeding control (at least 2)
- Tourniquet for limb injuries with severe, uncontrolled bleeding (at least 1)
- Triangular bandages (at least 4)
Burns
- Hydrogel burn dressings small (5x5cm) and large (20x20cm) (at least 2 of each)
- Burn gel sachets (at least 6)
- Cling film / non-adherent cover for burns do not use cotton-based dressings on burns
Eye Injuries
- Sterile eye pads (at least 6) eye injuries are among the most common construction site injuries
- Eye wash pods (15ml sterile saline, at least 10) for dust, concrete, chemical, and debris exposure
- Eyewash station permanently mounted near grinding, welding, cutting, or chemical storage areas
Fractures and Musculoskeletal Injuries
- SAM splints (rigid, mouldable) for arm and leg fractures (at least 2)
- Cervical collar (if available and trained first aider) for suspected spinal/neck injuries from falls
- Instant cold packs (at least 4) for sprains, strains, and fracture sites
Resuscitation and Shock
- CPR pocket mask with one-way valve and oxygen inlet port
- Emergency thermal / space blankets (at least 2) for treating shock and exposure
- Automated External Defibrillator (AED) strongly recommended on sites with more than 25 workers
Infection Control
- Disposable nitrile gloves (at least 10 pairs construction sites generate heavy glove use)
- Disposable aprons (at least 4)
- Biohazard waste bags (at least 6)
- Antiseptic wipes (at least 20)
- Antiseptic solution for wound irrigation
Envenomation Snakes and Spiders (Outdoor and Remote Sites)
- Pressure immobilisation bandages (at least 6 used in snakebite first aid)
- Snake bite reference card / instructions
- These are essential for sites in bush, rural, or semi-rural environments
Number of Kits Required on a Construction Site
The number of first aid kits on a construction site should be determined by a risk assessment, but general guidance is:
| Site Size / Configuration | Recommended Kit Provision |
|---|---|
| Small site up to 25 workers, single area | 1 high-risk kit |
| Medium site 26–50 workers or multi-level | 2 high-risk kits one per main work zone |
| Large site 50+ workers or multiple zones | 1 kit per 25 workers; additional kits at high-risk zones (electrical, welding, heights) |
| Vehicle / mobile workers on site | Portable kit in each work vehicle |
| Remote or isolated site | Enhanced kit with additional burn/snake/trauma supplies; satellite phone or emergency communication device |
First Aid Room Requirements
Larger construction sites are required to provide a dedicated first aid room. A first aid room is generally required when:
- There are 200 or more workers on site, OR
- The nature of the work creates a risk of injury or illness that cannot be adequately managed with a kit alone
A compliant first aid room must include:
- A wash basin with hot and cold running water
- A bed, stretcher, or treatment table
- Comprehensive first aid supplies (beyond the standard kit list)
- Emergency contact information displayed clearly
- Adequate lighting and privacy
Kit Storage and Placement on Site
- Position kits in locations accessible to all workers not inside locked site offices during active work hours
- In multi-storey construction, place a kit on each active floor or level
- Kits at welding and cutting stations must include additional burn dressings and eye wash
- Each kit must be clearly labelled with the AS 1319-1994 green and white first aid cross
- A notice board or safety induction should communicate kit locations to all workers before they commence work
Qualification Requirements for Construction First Aiders
Construction sites require first aiders with qualifications appropriate to the site’s risk level:
| Qualification | Code | Renewal |
|---|---|---|
| Provide First Aid | HLTAID011 | Every 3 years |
| Provide Cardiopulmonary Resuscitation (CPR) | HLTAID009 | Annually |
| Provide Advanced First Aid | HLTAID014 | Every 3 years |
| Provide First Aid in Remote Situations | HLTAID015 | Every 3 years (for isolated sites) |
Note: Workers in Queensland also require a White Card (CPCCWHS1001) before commencing construction work. This is separate from first aid qualifications.
Inspection and Maintenance on Construction Sites
Construction sites go through supplies faster than most workplaces. Best practice requires:
- Check kit contents at the start of each new project stage
- Restock after every incident immediately never wait for the monthly audit
- Formal audit every 3 months (more frequently than the 12-month standard for low-risk workplaces)
- Record all inspections and restocking events in the site safety register
- Remove and replace any expired items construction sites often have multiple teams accessing the same kit
Industry Statistics & Why Compliance Matters
The risks on Australian construction sites are not theoretical:
- Construction accounts for approximately 25% of all workplace fatalities in Australia annually, despite representing a smaller percentage of the total workforce
- Falls from height, being hit by moving objects, and muscular-skeletal injury are the leading causes of construction serious claims
- Head injuries in construction are among the most severe in any sector, often resulting in extended recovery periods
- The industry’s $641 billion annual output (2025–26 projection, ABS) means more workers on more sites making first aid preparedness more critical than ever
| Expert Insight: Construction site first aid is not simply about having a kit in the site office. Experienced site safety managers place kits at the point of risk next to the angle grinder station, on each scaffold level, in each work vehicle, and at the concrete pour zone. Accessibility in the 30 seconds after an injury can determine the outcome. |
