Control stations

Control stations
E.3.1 Such measures as are practicable shall be taken in respect of control stations outside machinery
spaces in order to ensure that ventilation, visibility and freedom from smoke are maintained, so
that in the event of fire the machinery and equipment contained therein may be supervised and continue
to function effectively.
In case a control station is served by a common ventilation system, which serves also other spaces, effective
local closing arrangements shall be provided.
Effective local closing arrangements mean that the provided ventilation systems shall be fitted with fire
dampers or smoke dampers which could be closed easily within the control station in order to maintain
the absence of smoke in the event of fire.
E.3.2 Alternative and separate means of air supply shall be provided; air inlets of the two sources of
supply shall be so disposed that the risk of both inlets drawing in smoke simultaneously is minimized.
Such requirements need not be applied to control stations situated on, and opening on to, an open deck
and where local closing arrangements would be equally effective.
Alternative and separate means of air supply may be provided also by combination of a mechanical supply
duct and a natural exhaust duct or vice versa provided that the fan is reversible
