.10       all fire hoses are hydrostatically tested;

 .11       breathing apparatus air recharging systems checked for air quality;

 .12       control valves of fixed fire-fighting systems should be inspected; and

 .13       air should be blown through the piping of extinguishing gas systems.

 The verification of the examinations and tests described in Sections 1.2 thru 1.6 above are an integral part of the annual statutory surveys for the SOLAS Safety Equipment Certificate.  The inspection and/or verification of the applicable items in Section 1.2 thru 1.7 shall be to the satisfaction of the attending Classification Society surveyor.

 1.7       Five-year service.

 At least once every five (5) years, the following inspections and tests should be carried out:

control valves of fixed fire-fighting systems should be internally inspected.

 

2.0       Fixed CO2 and Halon Systems.

            2.1       Verification of Cylinder Contents.

 Every two (2) years the contents of the cylinders are verified by weight or isotropic measurement as part of the survey for issuance of the SOLAS Safety Equipment Certificate. Weigh scales may be used to verify cylinder contents and recharging is required if the loss in charge is 10 percent or more.  Generally the weigh scales are included as part of the CO2 system equipment in order to satisfy FSS Code, Regulation 5.2.1.1.3.

          2.2       Hydrostatic Testing.

 All fixed CO2 and Halon cylinders must be hydrostatically tested as follows:

 .1         after each 20 years of service,

 .2         prior to recharging a discharged cylinder,

  .3         or when visual inspection reveals a potential defect.

 Hydrostatic test dates must be stamped on the cylinders.  Hydrostatic testing must be performed by an authorized servicing facility which has been certified by a government agency, or Classification Society, and by extinguisher manufacturer to perform this type of work.  The facility must be acceptable to the attending Classification Society surveyor.  The same facility should recharge the cylinders after testing to demonstrate serviceability.

            Refer to Marine Notice 2-011-11 for additional requirements regarding Fixed Halon System storage cylinder hydrostatic testing requirements.

 3.0       Portable Fire Extinguishers.

         3.1       Annual Survey.

 The examination of the fire extinguishers is an integral part of the annual statutory surveys for the SOLAS Safety Equipment Certification.  The fire extinguishers should be examined and, if necessary, serviced annually.  The annual servicing/examination of the portable fire extinguishers can be carried out by the crew, if the crew is properly trained and such servicing is acceptable to the vessel’s Classification Society, or by an authorized service facility.  The Classification Society surveyor must be satisfied with the condition of the extinguishers.

        3.2       Servicing of Fire Extinguishers by the Crew of a Vessel.

 A vessel crew may service powder, foam, or water type portable fire extinguishers subject to the following:

 .1         The equipment required to test, examine, and service the extinguishers is obtained and maintained in a calibrated and serviceable condition.

 .2         The crew is properly trained in the testing and examination, and servicing of fire extinguishers and the extinguisher manufacturer's servicing instructions are followed.

 .3         The testing and inspection is carried out to the satisfaction of the attending Classification Society surveyor, and if required by the surveyor, in the presence of the surveyor.

        3.3       Verification of Fire Extinguishers Contents.

 

Every two (2) years in conjunction with the issuance of the SOLAS Safety Equipment Certificate the contents of the cylinders must be verified.  Weighing of the portable CO2 cylinders in the presence of the Classification Society surveyor is an acceptable method of verification.  Other methods of determining contents of the cylinders, such as isotropic measurement, may also be accepted provided the equipment is properly calibrated, the operator of the device is trained and qualified in its use, and the Classification Society surveyor is satisfied with the measurements.  If an alternative method is used, spot checks of cylinder contents by weighing may be required to verify the accuracy and consistency of the measurement device.

       3.4.      Spare Charges, Additional Fire Extinguishers, and Refilling of Extinguishers.

 .1         For fire extinguishers of the same type, capable of being recharged on board, the spare charges should be provided as follows:

 100% for the first 10 extinguishers and 50% for the remaining extinguishers but not more than 60 (fractions to be rounded off to next whole number).

             .2    For extinguishers which cannot be recharged by the crew,additional  portable fire extinguishers of the same quantity, type, capacity  and number as determined in paragraph a above should be provided in lieu of spare charges. Instructions for recharging the extinguishers should be carried on board.  Periodic refilling of the cylinders should be in accordance with the manufacturer's recommendations.  Lacking same, refill is required when the extinguishing media starts to lose effectiveness.  Partially emptied extinguishers should also be recharged. Only refills approved for the fire extinguisher in question may be used for recharging.

             3.5       Authorized Servicing Facilities.

 The Classification Society surveyor may also accept a servicing certificate from an authorized servicing facility acceptable to the society for both the annual and biannual examination, servicing and verification of the portable fire extinguishers.

            3.6       Hydrostatic Testing of Portable Fire Extinguishers

All portable extinguishers shall be hydrostatically tested every 10 years; however, a hydrostatic test may also be required by the Classification Society surveyor or Marshall Islands Nautical Inspector if visual examination indicates a potential defect in the cylinder.  The hydrostatic test date must be permanently marked on the bottles.

 

           3.7       Hydrostatic Testing Facilities.

 Hydrostatic testing must be performed by a servicing facility which has been certified by a government agency or Classification Society, and by the extinguisher manufacturer to perform this type of work.  The facility must be acceptable to the attending Classification Society surveyor.  This same facility should recharge the cylinder after testing to demonstrate serviceability.

 4.0       Fixed Foam System.

      4.1       Foam Analysis.

 The first periodical control of foam concentrates stored on board should be performed after a period of three (3) years and annually thereafter.  A record of the age of the foam concentrates and of subsequent controls should be kept on board.

 5.0       Self-Contained Breathing Apparatus (SCBA).

 

       5.1       Annual Examination.

 All SCBAs shall be examined at least annually as part of the annual statutory survey for the Safety Equipment Certificate (SEC) or MODU Code certificate.  If applicable, the breathing apparatus air recharging systems should be checked for air quality as part of the annual statutory survey for the SEC or MODU Code certificate.

 

       5.2       Hydrostatic Testing of Self-contained Breathing Apparatus Cylinders.

 Hydrostatic testing of SCBA cylinders shall be carried out once every five (5) years.  The hydrostatic test date must be permanently marked on the bottles.  Intervals for hydrostatically testing cylinders of the ultra lightweight type may vary and will depend upon the requirements of the cylinder manufacturer and the vessel’s Classification Society.  Servicing of the cylinders must be performed to the satisfaction of the Classification Society surveyor.

 

     5.3       Spare Charges and Recharging of Breathing Apparatus Air Cylinders.

           .1 Two spare charges suitable for use with the breathing apparatus          should  be    provided for each required    apparatus.   

.2   If passenger ships carrying not more than 36 passengers and cargo ships are equipped with suitable located means for fully recharging the air cylinders free from contamination, only one spare charge is required for each required apparatus.

 

6.0              Emergency Escape Breathing Devices (EEBDs)

 6.1       Number and Locations

 .1         SOLAS requires at least two EEBDs to be located in the accommodations and additional EEBDs to be placed in the machinery spaces.  The Administration considers “machinery spaces” to mean Category A Machinery Spaces such as engine rooms and boiler rooms.  Auxiliary Machinery Spaces such as Steering Gear Compartments, Refrigeration Machinery Rooms, Bow Thruster Compartments, and alike do not have to be fitted with EEBDs.

 .2         Inasmuch as MSC/Circ.849 is referenced in SOLAS II-2/13.3.4 and 13.4.3, the Administration is treating the guidelines contained in the Circular as mandatory.

 .3         For compliance with the last sentence in Paragraph 4.6 of MSC/Circ.849, only those control spaces and workshops that are remotely located from the machinery space escape routes need be considered.

In achieving compliance with paragraph 4.6 of MSC/Circ.849, a minimum of two (2) EEBDs should be located on each level of the machinery space.  If a machinery space contains an enclosed primary escape trunk having a door at each level, only one (1) EEBD need be located on each level*.

 6.2       Maintenance and Care

         .1         The EEBD should be examined and maintained in accordance with the manufacturer’s instructions.

          .2         Sufficient spare EEBDs should be kept on board to replace units that are used, reach their expiry date, or otherwise become unserviceable.

           .3         Maintenance requirements, manufacturer’s trademark and serial number, shelf life with accompanying manufacture date and name of approving authority should be printed on each EEBD.



* The minimum fire hose length is 10 meters.  The length should not exceed 15 meters in machinery spaces and 20 meters in other compartments and on open decks (except that hoses of 25 meters in length may be used on open decks when the breadth of the ship is greater than 30 meters).

* The term “level” should be interpreted as meaning a deck where watchstanding personnel reside, workshops and control stations are located, or the crew may be employed during routine maintenance.  In essence, two (2) EEBDs are required only on those deck “levels” where people are likely to be employed.  Platform decks that serve to divide long ladders into segments and partial decks where personnel are not likely to be employed for any significant period of time are not considered as “levels” and do not require EEBDs.
