(c)
A vessel with bow and stern loading and discharge areas must have at least one self-contained dry chemical storage unit with an independent inert gas pressurizing source adjacent to the unit for each area.
(d)
Each dry chemical storage unit and associated piping must be designed for:
(1)
Sequential discharge of each hose line and each monitor for 45 seconds; and
(2)
Simultaneous discharge of all hose lines and monitors for 45 seconds.
(e)
Each fully charged dry chemical storage unit must have the greater of the following:
(1)
Enough dry chemical to provide for sequential discharge of each attached hose and monitor for 45 seconds.
(2)
Enough dry chemical to provide for simultaneous discharge of all attached hoses and monitors for 45 seconds.

(2)
Except for pre-aimed monitors, controlled from a location other than the monitor and manifold area.
(d)
Each dry chemical storage unit must have independent piping with a stop valve in the piping for each remote hand hose line and remote monitor where the piping connects to the storage container, if the unit has:
