Burns and scalds are among the most common injuries treated by workplace first aiders across Australia. A burn is a tissue injury caused by dry heat, electricity, chemicals, or radiation, while a scald is caused by moist heat such as steam or hot liquids — though both are treated the same way. Knowing how to respond correctly in the first few minutes can significantly reduce pain, limit tissue damage, and in serious cases, save a life. This guide covers everything you need to know: how to classify burns, the right first aid steps, what to avoid, when to call for emergency help, and how long recovery takes.

What Is the Difference Between a Burn and a Scald?
Burns vs Scalds: Are They Treated the Same Way?
People often use the terms “burn” and “scald” interchangeably, but there is a technical distinction. A burn is caused by dry heat sources such as fire, hot surfaces, electricity, chemicals, friction, or radiation from the sun. A scald is a type of burn caused by moist heat — typically boiling water, steam, hot oil, or other hot liquids.
Despite the difference in cause, the tissue damage they produce is similar, and the first aid treatment for both is identical. In Australian workplaces, scalds are particularly common in hospitality, manufacturing, and food production environments, while burns from electrical sources or chemical exposure are more frequent in construction and industrial settings. Regardless of the cause, the initial response is always the same: cool the injury, cover it, and seek medical help where needed.
How Are Burns Classified? Understanding 1st, 2nd and 3rd Degree Burns
Burns are classified by their depth — that is, how many layers of skin and underlying tissue they affect. In Australia, the three-tier classification system remains the most widely used in first aid education.
What Does a First Degree Burn Look Like?
A first degree burn (also called a superficial burn) affects only the outer layer of skin, known as the epidermis. The skin appears red, dry, and painful, similar to mild sunburn. There is no blistering. Most first degree burns heal without medical intervention within three to five days.
What Does a Second Degree Burn Look Like?
A second degree burn (partial thickness burn) penetrates through the epidermis and into the dermis below. The skin appears red and wet, and blistering is a hallmark sign. These burns are intensely painful and carry a risk of infection. Depending on the depth, they may require medical treatment and can take two to three weeks to heal.
What Does a Third Degree Burn Look Like?
A third degree burn (full thickness burn) destroys both layers of skin and may extend into underlying fat, muscle, or bone. The affected area may appear white, waxy, leathery, or charred. Importantly, third degree burns are often not painful at the burn site itself because the nerve endings have been destroyed. These injuries are medical emergencies requiring hospitalisation and specialist treatment.
| Degree | Layers Affected | Appearance | Pain Level | Healing Time |
|---|---|---|---|---|
| First Degree | Epidermis only | Red, dry, no blisters | Mild to moderate | 3–5 days |
| Second Degree | Epidermis + dermis | Red, wet, blistered | Severe | 2–3 weeks |
| Third Degree | All skin layers + deeper tissue | White, waxy, charred | Little to none | Requires surgery |
What Is the Golden Rule for Treating Burns?
Cool, Cover, Call — The Three Steps Every First Aider Should Know
The golden rule for treating burns in Australia is summarised in three words: Cool, Cover, Call. This simple mnemonic is endorsed by first aid organisations and health authorities nationwide because it captures the three most critical actions in the correct order.
Cool the burn first to stop the burning process and reduce pain. Cover the wound to protect it from contamination and infection. Call for emergency assistance when the burn is serious enough to warrant it.
Following this sequence helps prevent further tissue damage, reduces the risk of complications, and gives the injured person the best possible chance of recovery. Skipping or reversing any of these steps — for example, covering a burn before cooling it — can reduce treatment effectiveness and worsen the outcome.
What Are the First Steps for Treating Burns and Scalds?
Step 1: Remove the Person From Danger and Stop the Burning
Before treating any burn, ensure the scene is safe for both you and the injured person. Remove them from the source of heat if it is safe to do so. If clothing is on fire, follow the stop, drop, and roll technique. Remove any clothing or jewellery near the burn site, unless it is stuck to the skin — in which case, leave it and let medical professionals handle it. Do not attempt to peel away melted fabric.
Step 2: Cool the Burn With Running Water for 20 Minutes
Immediately run cool (not cold) water over the burn for a minimum of 20 minutes. This is the single most effective action you can take in the immediate aftermath of a burn. Cool running water draws heat away from the tissue, slows the burning process, reduces swelling, and provides meaningful pain relief. In Australia, this 20-minute guideline is supported by the Australian and New Zealand Burn Association (ANZBA) and is a cornerstone of nationally accredited first aid training.
Do not use ice, ice water, or freezing cold water. Extreme cold causes the blood vessels to constrict, which can worsen tissue damage and increase the risk of hypothermia — particularly in children or when a large body surface area is affected.
Step 3: Cover the Burn With a Sterile, Non-Stick Dressing
Once the burn has been cooled for the full 20 minutes, cover it loosely with a sterile, non-stick dressing or a clean, lint-free material such as cling film (applied lengthways, not wrapped tightly). Covering the burn protects the raw tissue from contamination and reduces pain by shielding the nerve endings from air exposure. Do not wrap a dressing tightly around a burn, as swelling can make a tight bandage dangerous.
What Is the Quickest Relief for Burns?
The fastest and most effective relief for a burn is cool running water — and it works best when applied immediately. Research consistently shows that the sooner cool water is applied after a burn injury, the greater the reduction in tissue damage and pain.
Many people are tempted to reach for ice packs, frozen peas, or commercial burn gels in the belief that they offer faster or better relief. In reality, none of these should be the first response. Ice and ice-cold substances can cause frostbite and vasoconstriction on already damaged skin. While some burn gels (such as those containing tea-tree or aloe vera) have a legitimate role in soothing minor burns after cooling, they are not a substitute for the 20-minute cool water protocol.
The simplest summary: access running water as quickly as possible, start the 20-minute clock, and resist the urge to improvise.
Should You Cover a Burn or Let It Air Out?
The Right Way to Cover a Burn Wound at Work
A common misconception is that burns should be left uncovered so they can “breathe” and heal faster. This is incorrect. Leaving a burn exposed to open air increases the risk of infection, accelerates moisture loss from the wound, and intensifies pain by leaving nerve endings unprotected.
After cooling, always cover a burn. The ideal covering is a sterile, non-adhesive dressing. In a workplace first aid kit, you should find appropriate dressings for this purpose. If no dressing is available, clean cling film (used lengthways over the wound, not wrapped around a limb) is an acceptable interim option. Avoid cotton wool, fluffy bandages, or any material that may shed fibres into the wound.
Do not burst blisters. The blister is a natural protective barrier formed by the body. Puncturing it increases the risk of infection and may worsen scarring.

What Should You Not Put on a Burn?
Common Burn Treatment Myths That Can Make Things Worse
Some of the most well-meaning first aid responses to burns are also among the most harmful. The following substances should never be applied to a burn wound:
| Substance | Why It Is Harmful |
|---|---|
| Butter or oil | Traps heat in the tissue and increases infection risk. |
| Ice or ice packs | Causes vasoconstriction and risks frostbite on damaged skin. |
| Toothpaste | Contains chemicals and abrasives that irritate the wound. |
| Egg whites | Risk of bacterial contamination, including salmonella. |
| Flour or baking soda | Traps heat and introduces foreign matter to the wound. |
| Adhesive bandages (on blisters) | Can tear the blister on removal, increasing infection risk. |
| Creams, lotions, or ointments | Can trap heat and interfere with clinical assessment. |
Why You Should Never Put Butter, Ice, or Toothpaste on a Burn
These are the three most common harmful home remedies applied to burns in Australia. Butter and oil are heat-retaining and create an environment in which bacteria thrive. Ice causes a secondary cold injury on top of the original burn. Toothpaste, despite its cooling sensation, contains compounds that irritate raw tissue and introduce unnecessary contamination risk.
The evidence is consistent and the guidance is clear: cool running water is the only substance that should be applied to a fresh burn. Everything else should wait until a medical professional advises otherwise.
Burns That Always Require Hospital Treatment
Even burns that do not initially appear severe may need hospital assessment if they cover more than one per cent of the body surface area in a child, if there is uncertainty about the depth, or if the burn was sustained in a high-risk environment such as an industrial site where chemical exposure may not be immediately visible. When in doubt, seek professional medical assessment rather than making that judgement call yourself.
How Long Do Burns Take to Heal?
First, Second and Third Degree Burn Healing Times
Healing time depends primarily on the depth of the burn, as well as the size of the affected area, the person’s age, and their general health.
- First degree burns typically heal within three to five days with no scarring.
- Superficial second degree burns generally heal within two weeks, often without scarring if treated promptly and kept free of infection.
- Deep second degree burns may take three to eight weeks and often result in some degree of scarring.
- Third degree burns do not heal on their own and almost always require skin grafting, with recovery measured in months rather than weeks.
Factors That Affect Burn Recovery in the Workplace
For workers returning to duties following a burn, factors such as the location of the burn, the physical demands of the role, infection risk, and psychological impact all influence recovery timelines. Employers have a duty of care under Australian Work Health and Safety legislation to support injured workers through appropriate modified duties and return-to-work planning.

Frequently Asked Questions
What is the best first aid for a burn?
The best immediate first aid for any burn or scald is to run cool (not cold) water over the affected area for 20 minutes, cover it with a sterile non-stick dressing, and call 000 if the burn is severe. Do not apply ice, butter, toothpaste, or any creams or lotions.
Should I pop a blister caused by a burn?
No. Blisters form as a natural protective response and should never be deliberately popped. Bursting a blister exposes the raw wound beneath to bacteria and significantly increases the risk of infection. If a blister bursts on its own, cover it with a clean, non-stick dressing and seek medical advice.
Can I use aloe vera on a burn?
Aloe vera gel has mild soothing and anti-inflammatory properties and may be appropriate for minor, superficial (first degree) burns after they have been properly cooled. However, it is not a substitute for the 20-minute cool water protocol and should not be applied to second or third degree burns without medical guidance.
How do I treat a chemical burn at work?
For a chemical burn, remove any contaminated clothing (using gloves if available) and flush the area with large amounts of cool running water for at least 20 minutes. Do not attempt to neutralise the chemical. Call 000 and, where possible, identify the chemical so emergency responders can be briefed. Refer to the relevant Safety Data Sheet (SDS) in your workplace for chemical-specific guidance.
What is the first aid treatment for a scald from boiling water?
Treat a scald from boiling water exactly as you would any other burn: cool with running water for 20 minutes, cover with a sterile non-stick dressing, and seek medical assessment if the scald is larger than a 50-cent coin, is on a sensitive area of the body, or involves a child or elderly person.
