Burns are one of the most common injuries in UK homes and schools, and the gap between the right response and a well-intentioned mistake can determine how a wound heals. In primary schools alone, scalds, friction burns, and contact burns appear regularly in accident books from a child catching a finger on a hot glue gun in a design technology lesson to a staffroom kettle left too close to the edge.
The correct response in those first few minutes matters more than any treatment applied days later, and both teachers and parents benefit from knowing it before an incident happens rather than searching for guidance in the middle of one.
This guide follows NHS-recommended first aid protocol and expands it with school-setting guidance, practical advice on treating burns during recovery, and a myth-busting section that addresses the most common household mistakes. It covers all three degrees of burn severity, explains the critical 20-minute cooling rule, and provides a clear decision framework for when to call 999, when to ring 111, and when home care is sufficient. The FAQ section addresses the questions that appear most often from parents and school staff in real-world burn situations.
LearningMole, the UK educational platform founded by former primary teacher Michelle Connolly, has produced this resource to support teachers delivering PSHE health and safety content, school first aiders refreshing their knowledge, and parents who want to respond with confidence. Used alongside LearningMole’s curriculum-aligned PSHE and science resources, this guide provides a foundation for classroom discussions about personal safety that meet KS1 and KS2 National Curriculum objectives.
Identifying how serious a burn is determines every decision that follows, from how long to cool it to whether it needs hospital treatment. The three degrees of severity map directly to skin depth, and recognising the signs takes less than a few seconds once you know what to look for.
| Degree | Layers affected | Appearance | Pain level | First aid needed |
|---|---|---|---|---|
| First-degree (superficial) | Outer skin layer only | Red, dry, no blisters | Moderate to high | Cool water, keep clean, monitor |
| Second-degree (partial thickness) | Outer layer plus dermis below | Blistered, wet, deep red | Severe | Cool water, cling film, seek medical advice |
| Third-degree (full thickness) | All skin layers, possibly deeper | White, leathery, or charred | Little pain (nerve damage) | Emergency services (999) immediately |
First-degree burns, such as mild scalds and sunburn, typically heal within one to two weeks without medical intervention. Second-degree burns require professional assessment because the risk of infection and scarring is significant. Third-degree burns are always a medical emergency. If you are uncertain which category a burn falls into, treat it as more serious and seek advice.
“Understanding the severity of a burn before you act is the first step in giving effective first aid. Rushing to cover or treat a burn before cooling it properly is one of the most common mistakes we see, and it extends the injury.” Michelle Connolly, Founder of LearningMole and former teacher with over 15 years of classroom experience
Remove the person from the heat source before anything else. For a scald, move them away from the hot liquid source. For a contact burn, remove the object causing contact if safe to do so. For a clothing fire, the stop, drop, and roll technique remains the correct response. Running increases airflow and spreads flame.
Once away from the source, check for safety before approaching. This is especially important in schools: if a pupil has made contact with an electrical source, disconnect the power before touching the child. For chemical burns, put on gloves before handling the affected area, and brush away any dry chemical before applying water.
Run cool (not cold) water over the burn for at least 20 minutes. This is the single most important action in burn first aid and the step most often cut short. Many people stop when the pain reduces, typically after five or ten minutes, but the tissue beneath the skin continues to burn even when the surface feels cooler. The full 20 minutes are required to stop the ongoing thermal transfer into deeper layers that determines the final extent of the injury.
The water temperature should be comfortably cool, around 15-25°C. Cold water, and especially ice or iced water, causes vasoconstriction and actually drives heat deeper into the tissue. Ice is contraindicated; it does not help and causes additional damage.
For burns covering large areas or affecting children, monitor the casualty’s temperature during cooling and use a blanket over unaffected areas to prevent hypothermia. In a school setting, designate a second adult to manage the rest of the class so the injured child receives uninterrupted care.
Once cooling is established, gently remove any clothing, watches, or jewellery near the burn site. Skin swells rapidly after a burn injury; what fits comfortably now may become a tourniquet within minutes. A ring on a burned finger needs to come off during cooling, not after. A useful analogy for children learning about this in a PSHE context: it is the same reason you remove tight shoes immediately after a foot injury, before swelling makes it painful.
Do not remove anything stuck to the burn. Fabric or material fused to burned skin must be left for medical professionals to address, as removing it tears the damaged tissue beneath and dramatically increases the risk of infection.
After the full cooling period, cover the burn loosely with cling film. Cling film is the recommended first aid dressing for burns in UK clinical guidance for several reasons: it does not adhere to the wound, it keeps the area moist, it reduces pain by shielding nerve endings from air exposure, and it is transparent enough for medical staff to assess the burn without removing the dressing.
The technique matters. Lay the cling film over the burn in strips rather than wrapping it around a limb. Wrapped cling film can constrict the area if swelling increases, creating the same tourniquet risk as tight jewellery. If cling film is unavailable, a clean, non-fluffy material such as a new polythene bag works for hand or foot burns. Do not use cotton wool, bandages with loose fibres, or anything that sheds material fibres become embedded in the wound.
This decision matrix covers the most common burn scenarios. When in doubt, call 111. Advisors can assess the situation and direct appropriately.
| Situation | Action |
|---|---|
| Third-degree burn (any size) | Call 999 immediately |
| Burn larger than the casualty’s palm | Call 999 |
| Burn on the face, hands, feet, genitals, or a joint | Call 999 |
| Chemical or electrical burn | Call 999 |
| Child under 5 with any burn larger than a 2p coin | Call 999 |
| Signs of shock (pale, clammy, confused, faint) | Call 999 |
| Second-degree burn on an adult, smaller than a palm | Call 111 or attend urgent care |
| Minor first-degree burn, home care adequate | Cool, cover, monitor for infection |
| Any uncertainty about severity | Call 111 |
For burns in a school setting, also complete the accident book before the end of the day, regardless of severity. If a child is taken to the hospital by emergency services, the school must notify the parents or guardians immediately and follow the school’s critical incident procedure.
This is the area where the most confusion exists. The ointment question matters because the wrong product applied too early can trap heat, introduce infection risk, or interfere with medical assessment.
| Product | When to use | When to avoid | Notes |
|---|---|---|---|
| Cool running water | Immediately, for 20 minutes | N/A | Always the first treatment; nothing replaces it |
| Cling film | After cooling, as an initial dressing | Do not wrap around limbs | Best for all burn types as an immediate dressing |
| Aloe vera gel (pure) | Minor first-degree burns during healing | Open blisters or broken skin | Natural anti-inflammatory; apply after cooling is complete |
| Petroleum jelly (Vaseline) | During healing, on closed skin | Immediately after a fresh burn | Traps heat on fresh burns; useful later to keep healing skin moist |
| Antibiotic ointment | Minor burns to reduce infection risk | Deep or large burns | Over-the-counter options appropriate for small first-degree burns |
| Burn gel (hydrogel dressing) | Immediate pain relief after cooling | As a substitute for the 20-minute cooling stage | Available in first aid kits; cools and protects simultaneously |
| Honey (medical grade) | Some healing-phase applications | As emergency first aid | Not a first-response treatment; some evidence for antimicrobial properties in healing |
For second-degree burns and above, do not apply any cream, ointment, or gel. These wounds need medical assessment first. During the healing phase of minor burns, keeping the skin moist with aloe vera or a gentle moisturiser supports recovery. Change any dressings daily, wash hands before doing so, and watch for signs of infection: increased redness, spreading warmth, swelling, pus, or a temperature above 38°C.
A school burn incident presents a specific challenge: the first aider must manage the injured child while maintaining the safety and supervision of the rest of the class. A lone teacher cannot run cool water over a burn for 20 minutes and simultaneously supervise a classroom.
The correct procedure is to:
For friction burns common in PE, particularly on artificial grass or hard courts, the same cooling protocol applies. These burns look less dramatic than scalds but can cause significant skin damage, particularly in a high-speed fall. Cool them for 20 minutes and assess the skin condition before covering.
LearningMole’s PSHE resources include age-appropriate safety content that helps children understand why first aid procedures work, including how heat transfers through skin and why the 20-minute rule exists. This gives teachers a way to contextualise safety learning rather than treating it as abstract rule-following.
Butter or cooking oil. Both trap heat inside the wound rather than drawing it out, prolonging the burn. They also create an ideal environment for bacterial growth. Do not use them at any stage of burn treatment.
Mustard. Despite persistent folklore suggesting that mustard draws heat from a burn, there is no evidence to support this claim, and mustard’s acidity can irritate damaged skin. Cool running water is the only evidence-based immediate treatment.
Toothpaste. Toothpaste is abrasive, contains chemicals inappropriate for open wounds, and, like butter, traps heat. It is one of the most common first aid errors seen in emergency departments.
Ice or ice packs. Ice causes vasoconstriction, forcing heat deeper into the tissue and potentially causing frostbite on already damaged skin. Always use cool running water.
Petroleum jelly on fresh burns. Vaseline is a useful product during the healing phase of minor burns, but when applied immediately, it seals in heat. Only use it once the burn has fully cooled and entered the recovery stage.
Popping blisters. Burn blisters form as part of the body’s natural protection mechanism. The fluid inside is sterile and acts as a barrier against infection. Bursting a blister removes this protection, significantly increasing the risk of infection.
For teachers covering health and safety, personal safety, and PSHE, first aid content aligns directly with KS2 Health and Prevention objectives in the UK National Curriculum. LearningMole provides curriculum-aligned resources that help make safety concepts tangible for primary-aged learners.
“Teaching children about first aid is not just a health topic; it is a lesson in cause and effect, in understanding how the body works, and in taking responsibility for the people around them. Children who understand why we cool a burn for 20 minutes are far more likely to remember to do it.” Michelle Connolly, Founder of LearningMole and former teacher with over 15 years of classroom experience
For parents supporting safety education at home, LearningMole’s resources cover a range of health and science topics in child-friendly formats that complement what children learn in school.
No. Ice and iced water can further damage burned skin. The cold causes vasoconstriction, which drives heat deeper into the tissue rather than drawing it out, and the extreme cold can cause frostbite on skin that is already compromised. Always use cool running water at around 15 to 25°C. The water should feel comfortably cool to the touch, not painfully cold.
The NHS-recommended minimum is 20 minutes under cool running water, and this should begin as soon as possible after the injury. Many people stop after five or ten minutes when the pain reduces, but the deeper layers of tissue continue to sustain damage even when the surface feels cooler. The 20-minute mark is the point at which thermal transfer into deeper tissue is substantially reduced.
No. Burn blisters form as the body’s natural response to protect the damaged tissue below. The fluid inside is sterile and acts as a barrier against bacterial infection. Popping a blister removes this protection and dramatically increases the risk of the wound becoming infected. If a blister breaks on its own, clean the area gently with mild soap and water, apply a thin layer of antibiotic ointment, and cover with a non-stick sterile dressing.
During the immediate response phase, cool running water is the only appropriate treatment. After 20 minutes of cooling, cling film applied loosely (not wrapped) is the recommended first dressing. During the healing phase of minor first-degree burns, pure aloe vera gel or a gentle moisturiser can help maintain skin moisture and support recovery. For anything beyond a very minor burn, seek medical advice before applying any cream or ointment.
Call 999 if the burn is third-degree (white, leathery, or charred appearance), if it covers an area larger than the casualty’s palm, if it is on the face, hands, feet, genitals, or across a joint, if it was caused by electricity or chemicals, if the casualty shows signs of shock, or if a child under five has any burn larger than a 2p coin. When in doubt, call 111 for guidance. Advisors can assess the situation and advise whether emergency services are needed.
Yes. The content aligns with the KS2 Health and Prevention strand of the PSHE curriculum, specifically the objective that children should know basic first aid procedures and understand why they work. The burn severity table and step-by-step cooling guidance are written at an accessible level for Year 5 and Year 6, and the myth-busting section works well as a discussion activity. LearningMole’s PSHE resources include additional age-appropriate safety content for teachers to use alongside this guide.
Cling film is the recommended emergency dressing because it does not adhere to the wound surface, meaning it can be removed without damaging the injured tissue. It keeps the area moist, which supports healing and reduces pain from exposure to air. It is also transparent, allowing medical staff to assess the burn without removing the dressing. The key technique is to lay it in strips rather than wrapping it around the limb. Wrapping can create a tourniquet effect if the area swells.
Friction burns, also called abrasion burns or brush burns, should be treated with the same cooling protocol as thermal burns. Run cool water over the area for 20 minutes. The skin damage from a high-speed friction burn can be significant even if it looks less severe than a scald. After cooling, gently clean any embedded debris if the wound is not too deep, apply a thin layer of antibiotic ointment, and cover with a non-stick sterile dressing. If the abrasion is deep, covers a large area, or shows signs of infection within 48 hours, seek medical advice.
Effective first aid reduces injury in the immediate aftermath, but the days that follow matter equally for minor burns managed at home. Keep the burn site clean by washing gently with mild soap and water once daily, then pat dry. Change dressings daily and inspect the wound each time. A minor burn should show visible improvement within 48 to 72 hours, redness should reduce, and any swelling should begin to ease.
Signs that require medical attention include worsening pain rather than improvement, spreading redness around the wound edge, warmth extending beyond the burn site, pus or cloudy discharge, a fever above 38°C, and any skin that begins to break down beyond the original burn area. These are indicators of infection, which is the primary complication of burns managed at home, and they warrant urgent care rather than monitoring.
For schools, this recovery phase is relevant if a pupil returns following a burn injury. Teaching staff should be aware of any dressings in place, avoid activities that could disturb the wound or expose it to friction, and keep the parents’ or guardians’ contact details readily accessible if symptoms change during the school day. A brief note from the school nurse or first aider in the pupil’s file ensures continuity of care across the school day.
