F.R.A.M.E.
Case study 26. Fire safety for a drink manufacturing plant.
The factory of this alcoholic drink manufacturer developed from a small distillery into a large
mixing and bottling unit. During the development process modifications and extensions were
numerous, so that the plant needed a thorough fire safety improvement program. The insurers
practically imposed sprinklers for the whole plant, and the question was raised if this was
enough to guaranteed also a level of fire safety that was acceptable for the authorities and
that guaranteed also business continuity.
A number of FRAME calculations were made to check the new situation.
