Bilge Blower Systems
•
The bilge blowers remove explo-
sive fumes from the engine room
and lazarette bilge areas.
•
Fresh air is drawn into these
compartments through the vents.
To make sure the bilge areas
are properly ventilated:
•
Always run the bilge blowers for
at least four minutes before start-
ing the engines or the generator.
•
Use the "sniff test" to check the
bilge areas for fuel vapors before
starting the engines or
the generator.
•
Continue to run the blowers until
your yacht has reached
cruising speed.
•
Always run the blowers when
operating your yacht below
cruising speed.
