b) duration of each flood,
c) alarm count in each flood, and
d) peak alarm rate for each flood.

At a minimum, a target peak alarm flood rate should be defined, such as in the guidance provided by the ASM Consortium or Engineering Equipment and Materials Users Association (EEMUA), to establish trigger points that require alarm performance improvement actions.
