Whilst there was much criticism of the lack of fire sprinkler systems, Geoff Wilkinson, the building regulations columnist for the "Architects' Journal", wrote in a comment on 14 June, before the cause was known ("we should avoid speculating"), that if a leaking gas riser or the cladding were at fault, sprinklers would have had little effect. He said he had seen extracts of a fire risk assessment and talk of flammable material stored in the common walkways, suggesting poor overall management.
