(b) The lockout valve must be a manually operated valve located in the discharge manifold prior to the stop valve or selector valves. When in the closed position, the lockout valve must provide complete isolation of the system from the protected space or spaces, making it impossible for carbon dioxide to discharge in the event of equipment failure during maintenance. (c) The lockout valve design or locking mechanism must make it obvious whether the valve is open or closed. (d) A valve is considered a lockout valve if it has a hasp or other means of attachment to which, or through which, a lock can be affixed, or it has a locking mechanism built into it. (e) The master or person-in-charge must ensure that the valve is locked open at all times, except while maintenance is being performed on the extinguishing system, when the valve must be locked in the closed position.

Systems of this type are designed to give primary protection to the spaces over the cargo tanks. (b) Rate of application. The water rate of the foam production equipment shall be determined as follows: (1) For usual petroleum products the rate of supply of foam solution shall be not less than the greatest of the following: (i) 0.6 liters/min per square meter of cargo tanks deck area, where cargo tanks deck area means the maximum breadth of the ship multiplied by the total longitudinal extent of the cargo tank spaces; (ii) 6 liters/min per square meter of the horizontal sectional area of the single tank having the largest such area; or (iii) 3 liters/min per square meter of the area protected by the largest monitor, such area being entirely forward of the monitor, but not less than 1,250 liters/min. (2) For polar solvent products (e.g. alcohols, ketones, etc.) the water rate shall be determined for each vessel. The rate will depend upon the vessel design, products to be carried and foam system to be used. (c) Supply of foam-producing material. Each deck foam system must have a supply of foam-producing material sufficient to operate the system at its designed rate of foam production for the following periods: (1) For installations contracted for on or after January 1, 1970, 15 minutes without recharging, except as required in paragraph (c)(2) of this section. (2) For installations on ships that have a keel laying date on or after January 1, 1975, 20 minutes without recharging. (d) Separate supply of foam-producing material. Where the same foam-producing material may be used for this system as well as a fixed foam system, separate supplies need not be provided for each space protected. The total available supply shall be at least sufficient for the space requiring the greatest amount. (e) Water supply. Suitable pumps shall be provided capable of producing the required water rate.
