Burn Severity: Understanding First-, Second-, and Third-Degree Burns

Burns are categorized by how deeply they damage the skin. Severity is influenced by temperature, contact time, and the body area affected. Knowing how burns differ helps with first aid awareness and recognizing when more advanced care may be required.

First Aid & Workplace Relevance

Burns are common in daily life and in workplaces such as kitchens, manufacturing, construction, electrical trades, and outdoor seasonal work. At home, burns often occur in kitchens and with hot liquids, steam, or heated appliances. Public first aid awareness helps people manage minor burns safely and recognize when a burn is more serious.

Scenario

During a community barbeque, a teen accidentally brushed their hand against a hot grill plate and yelped from pain. A trained first aid rescuer recognized signs of a superficial burn and immediately cooled the area under cool running water for several minutes while reassuring them. The discomfort eased and the rescuer reminded them not to apply ice or butter to the burn.

Types of Burns

First-Degree (Superficial) Burns

Affects only the epidermis, the top layer of skin.
Common features:

Redness
Mild swelling
Pain
Possible peeling as it heals

These burns commonly result from brief contact with a hot object or mild sunburn. Most heal within days.

Second-Degree (Partial-Thickness) Burns

Damages the epidermis and parts of the dermis.
Features may include:

Blisters
Deep or irregular redness
Wet or shiny appearance
Significant pain due to exposed nerve endings

These burns may take longer to heal and may require medical assessment to prevent complications.

Third-Degree (Full-Thickness) Burns

Involves full destruction of the epidermis and dermis.
Features may include:

Dry, leathery, charred, black, or white skin
Swelling
Little or no pain due to nerve damage

These burns are considered medical emergencies and may require specialized treatment and long-term healing support.

Causes & Mechanisms

Burns can result from:

Hot surfaces, steam, or boiling liquids
Flame or high-heat exposure
Electrical sources
Chemicals
Prolonged sun exposure

General First Aid Education for Burns

Public first aid guidelines often recommend:

Cool the burned area with cool running water (not ice)
Protect the burn with a clean, non-stick dressing
Avoid home remedies such as butter, oil, or toothpaste
Monitor for signs of infection as healing progresses

Burns involving the face, hands, feet, genitals, or larger body areas may require medical care.

Prevention & Workplace Considerations

Use thermal protection (oven mitts, gloves, PPE)
Follow workplace safety protocols for heat, flame, and chemicals
Check water temperatures in kitchens and childcare settings
Use sun protection outdoors to reduce UV burns

FAQ

Q1: Why do second-degree burns blister?
Damage to the lower skin layers allows fluid to collect under the surface, forming blisters.

Q2: Why might third-degree burns not hurt?
Nerve endings may be destroyed, reducing the sensation of pain at the site despite serious tissue damage.

Q3: How do you know if a burn needs medical care?
Burns that blister, cover larger areas, involve sensitive regions, or show signs of infection should be assessed by a healthcare professional.

Q4: Can sunburn be considered a first-degree burn?
Mild sunburn is typically superficial, though severe sunburn may blister like a second-degree burn.
