(f) Cylinders. (1) Each cylinder must be securely fastened and supported, and where necessary protected against injury. Cylinders must be located outside the space protected.
(2) Each cylinder must be mounted in an upright position or inclined not more than 30° from the vertical, except that cylinders which are fitted with flexible or bent siphon tubes may be inclined not more than 80° from the vertical.
(3) Each cylinder used for storing extinguishing agent must be approved and marked in accordance with Department of Transportation regulations.
(4) Each cylinder must be mounted so it is readily accessible and capable of easy removal for recharging and inspection. Cylinders must be capable of being weighed in place.
(5) Where subject to moisture, cylinders must be installed so that a space of at least 2 inches is provided between the flooring and the bottom of the cylinders.
(6) Each cylinder storage area must be properly ventilated and the temperature inside must not exceed 130 °F.
(g) Provision must be made by means of plugs, covers, dampers, etc., to prevent the admission of air into the space protected.
(h) Systems must be fitted with a delayed discharge and an alarm bell arranged so the alarm sounds for at least twenty seconds before the carbon dioxide is released into the space.
(a) The minimum number of portable fire extinguishers required on each vessel is determined by the Officer in Charge, Marine Inspection, in accordance with Table 169.567(a) of this section and other provisions of this subpart.
|Space||Portable fire extinguishers|
|Minimum required rating||Quantity and location|
|Propulsion machinery space without fixed extinguishing system||40-B:C||2.|
|Propulsion machinery space with fixed extinguishing system||40-B:C||1 in the vicinity of the exit.|
|Living space and open boats||2-A||1 per 1,000 cubic foot of space.|
|Galley (without fixed system)||40-B:C||1 per 500 cubic foot.|
|Spare Units||2-A||10 percent of the required number rounded up.|
(b) Table 169.567(a) of this section indicates the minimum required classification for each space listed. Extinguishers with larger numerical ratings or multiple letter designations may be used if the extinguishers meet the requirements of the table.
(c) All portable fire extinguishers installed on vessels must be of an approved type.
(d) Portable fire extinguishers must be stowed in a location convenient to the space protected.
(e) Portable fire extinguishers must be installed and located to the satisfaction of the Officer in Charge, Marine Inspection.
(f) Portable fire extinguishers which are required to be protected from freezing must not be located where freezing temperatures may be expected.
(a) Each vessel must carry at least the number of fire axes set forth in Table 169.569(a). The Officer in Charge, Marine Inspection may require additional fire axes necessary for the proper protection of the vessel.
|Length||Number of axes|
(b) Fire axes must be stowed so as to be readily available in the event of emergency.
(c) If fire axes are not located in the open or behind glass, they must be placed in marked enclosures containing the fire hose.
(a) A lockout valve must be provided on any carbon dioxide extinguishing system protecting a space over 6,000 cubic feet in volume and installed or altered after [July 9, 2013. “Altered” means modified or refurbished beyond the maintenance required by the manufacturer's design, installation, operation and maintenance manual.
(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.
(f) Lockout valves added to existing systems must be approved by the Commandant as part of the installed system.
Each carbon dioxide extinguishing system installed or altered after July 9, 2013, must have an approved odorizing unit to produce the scent of wintergreen, the detection of which will serve as an indication that carbon dioxide gas is present in a protected area and any other area into which the carbon dioxide may migrate. “Altered” means modified or refurbished beyond the maintenance required by the manufacturer's design, installation, operation and maintenance manual.
