Burn and Explosion Injury Claims

How burns are classified, and why it drives everything

Two measurements shape both the treatment and the value of a claim: depth and extent. Depth runs from superficial burns affecting only the outer skin, through partial thickness burns into the dermis, to full thickness burns destroying the skin entirely — and beyond that to burns reaching muscle or bone. Extent is measured as a percentage of total body surface area.

Together these determine whether someone needs a specialist burn centre, how much grafting is required, and what permanent impairment is likely. A third factor changes the prognosis sharply: inhalation injury, where hot gases or smoke damage the airway, is frequently the element that turns a survivable burn into a critical one.

The mechanisms, and what each one implicates

Industrial burns arrive by distinct routes, and each points at a different set of records and a different potential defendant.

• Arc flash — an electrical fault ionising the air, producing extreme heat, light and a pressure wave. Points at electrical safe work practices, energised-work justification and arc-rated PPE.
• Flash fire — a fast-moving fire through an ignited vapour or gas cloud. Points at gas detection, hot work permits and flame-resistant clothing certification.
• Chemical burns — acids, alkalis and other corrosives, which can continue destroying tissue long after contact. Points at labelling, safety data sheets and the adequacy of emergency washing facilities.
• Steam and scald burns — from line breaks, relief valve discharge or pressurised hot water. Points at isolation procedures and pressure system maintenance.
• Contact burns — hot surfaces, molten metal, heated equipment. Points at guarding, insulation and thermal protection.
• Explosion burns — vessel rupture, vapour cloud ignition or combustible dust, usually combining thermal injury with blast trauma.

Combustible dust — the hazard most sites underestimate

A surprising range of ordinary materials becomes explosive as fine airborne dust: sugar, flour, grain, wood, coal, and metals including aluminium and magnesium. Above a certain airborne concentration, with an ignition source present, the dust burns almost instantaneously and produces a pressure wave.

The characteristic pattern is what makes these events so destructive. A relatively small primary explosion disturbs dust that has settled over years on beams, ledges, ductwork and cable trays. That suspended dust ignites in a secondary explosion which is frequently far larger than the first and reaches areas the initial event never touched.

Because the settled dust accumulates gradually and visibly, these cases usually turn on housekeeping records, dust collection system design and maintenance, and whether any prior hazard assessment identified the risk and what was done about it.

Protective clothing, and when it becomes a product claim

Flame-resistant clothing is certified against specific hazards, and the certifications are not interchangeable. Garments rated for flash fire protection are tested against a different exposure from arc-rated garments used for electrical work. Issuing the wrong one, or allowing flammable synthetic layers to be worn underneath, produces injuries the clothing was never going to prevent.

Where clothing ignited, melted onto the skin, or failed to perform to the rating it was sold under, a product liability claim against the manufacturer may exist entirely separately from anything the employer or site operator did.

That claim depends on physical evidence which is routinely lost — the garment is usually cut away during emergency treatment and discarded. Preserving it, and the purchase and issue records showing what rating was specified, is one of the most time-critical steps in a burn case. See defective equipment claims and evidence for your claim.

The long arc of a burn injury

Burn cases are valued badly when they are valued early, because the most expensive consequences appear late. Acute treatment is only the beginning: grafting is often staged across multiple procedures, and scar tissue continues maturing for a year or more after the wound closes.

Contractures — scar tissue tightening across a joint — can permanently restrict movement and require release surgery, sometimes repeatedly. Hypertrophic scarring may need ongoing pressure garment therapy. Damaged skin loses the ability to regulate temperature and sweat, which can permanently limit what work someone can do in a hot environment. Where inhalation injury occurred, reduced respiratory function may be lifelong.

There is also a well-documented psychological dimension — visible scarring, particularly to the face and hands, carries consequences that are real and separately compensable in a civil claim, though not through workers’ compensation. For injuries at this level see catastrophic injury claims.

Who can be held responsible for an industrial burn or explosion?

Usually more than one party, and frequently not your own employer. Workers' compensation bars a claim against the employer but leaves every other company untouched — and industrial fires almost always involve several.

Depending on how the event started: the plant operator controlling the site, a maintenance contractor whose work supplied the ignition, the manufacturer of equipment that failed, a chemical supplier whose labelling or documentation was inadequate, or the maker of protective clothing that underperformed its rating. Working out which applies is where the substantive value of a burn case usually sits — see third-party work injury claims and process plant accidents.
