WARNING
The Water Washdown System (WWS) is not designed nor intended to
be a stand alone fire extinguishing system. It is designed to be used
in conjunction with the installed FM-200 Fixed Fire Extinguishing
System.
In the event of an onboard fire emergency failure to activate the FM-200
Fixed Fire Extinguishing could result in equipment damage, death or
serious injury.
WARNING
To reduce temperatures within the protected space and manage the risk
of HF exposure to humans, the WWS is designed and intended to be
operated for a minimum of 15 minutes. This procedure should be followed
to the full extent or death or serious injury could occur.
NOTE
Upon automatic shutdown of ships service generators, the emergency
diesel generator set will automatically start and place itself on line
within 45 seconds.
Operate the WWS for a minimum of fifteen (15) minutes. During the WWS operating period,
approximately every three (3) minutes, open valve WWS-2, engine room WWS strainer blow off
for approximately ten (10) seconds. This will allow any foreign matter to be flushed from the in-
line strainer basket.
c. Activation Procedures For Tunnel WWS
Evacuate all personnel from the protected space.
