Perhaps a different approach is for enforcing authorities to challenge the responsible person on the issue of competences of the assessor. and how suitable and sufficient the fire risk assessment is.
I don`t have a problem with people having a go in a simple building new build, ground floor only or ground and first floor only, low occupancy, persons awake and familiar with the building. With a little bit of assistance they can get it right.
Where I do have a problem is people thinking the can do a fire risk assessment of large complex buildings. I have come across joe public carrying out FRA of office blocks with 10 floors. They have missing the significance of dry risers, firefighting lifts, ill fitting fire resistant doors etc.
I don`t really understand why they get upset when I tell them they don`t have the competencies to do the assessment.
