Cases

Typical scenarios within this site’s subject: questions to ask, materials to prepare and points that can be examined.

Typical scenarios

The deepest charring was treated as the fire's origin

If a report locates fire origin at the deepest char, damage intensity alone does not identify where burning began. A window may be nearby and heat-exposure durations for different structures unknown. The explanation must address the whole pattern of effects rather than one selected area.

Typical scenarios

Later fire photographs show changes caused by dismantling

If a report relies on photographs taken after room clearance, item positions and exposed surfaces may reflect dismantling rather than the original scene. The records may have been made at different times, so their contents must be linked to the particular conditions, dates and object under review.

Typical scenarios

A fire plan and photographs use different room labels

If an inspection record and a later plan label rooms differently, photographs may be assigned to the wrong area. Suppose the area of initial burning is disputed and some images were taken after damaged objects were moved.

Typical scenarios

An electrical fire explanation relies on a single melted wire

If a report treats a melted wire as sufficient proof of a fire’s cause, its reasoning needs examination. Damage to a component and ignition are different circumstances whose connection must be investigated. Location, circuit condition, other damage and the sequence of events all matter.
