Many fire risk assessments (FRA) are considered inadequate because too the assessors fail to examine the structure in detail - for example looking above false ceilings. Grenfell Tower in London was considered a medium fire risk but in spite of this at least 72 people died in the Grenfell Tower fire, FRA also failed with the Lakanal House fire. Prof Arnold Dix described the FRA system as only a, "box-ticking exercise". Dix maintains cladding is not taken into account, how hard it is to evacuate a burning tower block is not taken into account, fire risks inside flats such as old electrical equipment that is at greater risk of catching fire and combustible bedding are not taken into account.
