The condition that is not a characteristic of charred materials found in fire fatalities is the absence of smoke inhalation injuries. When materials are charred, it typically indicates that they have been subjected to high heat and flames, often leading to varying degrees of combustion and heat damage. Charred remains suggest that there was direct exposure to flames, high-intensity heat, and likely a prolonged duration of fire, as it takes time for materials to become fully charred.

In fire fatalities, victims frequently experience smoke inhalation injuries, which can occur even if they were outside the direct flames or charred materials. These injuries are associated with the toxic gases released during combustion and can happen alongside other types of thermal injury. Therefore, charred materials and smoke inhalation injuries can coexist, making the absence of smoke inhalation injuries an inconsistent condition in instances of charred materials in fire fatalities.
