It is for these reasons that recent legislation has been increased and there are likely to be further more stringent requirements to be introduced. Significant fines and even custodial sentences are not uncommon to imposed onto those responsible for the building fire safety, even when their hasn't been a loss of life. Simply believing the the responsibility should be passed to the original contractor is not a sufficient excuse.

As the person being responsible for a building upon completion and handover from the contractor, are you sure it is fully compliant to safety standards? One crucial element of that compliance is the regular servicing and preplanned maintenance of the AOV and smoke ventilation systems. Not only is this requirement of compliance but in the long is far more cost effective as is likely to prolong the life expectancy of the systems.
