   PROCEDURES FOR SERVICING THE BRITANNIA MARINE RANGE OF HAND PORTABLE FIRE



Introduction


The commissioning and servicing of fire fighting equipment must be carried out by a competent
person using the correct tools to follow the procedures of BS 5306, part 3: 2009 and the
manufacturer’s instructions.


Servicing and recharging should be carried out in a clean dry environment. All recharge
materials and spare parts must be as specified by the manufacturer.


In the event that an extinguisher cannot immediately be rendered suitable for continued
service, it must be marked 'unfit for service' until it can be repaired/recharged.

The competent person must advise the user of any equipment, which is either condemned or
unfit for service and make any recommendations for replacement and/or remedial work.

Always check the security and suitability of the hanging bracket, and that the extinguisher is of
the right type for the prevalent risk.

If the extinguisher is to be sited in a hazardous/corrosive environment i.e. marine use, the
inspection periods should be more frequent. The effects of the environment should be
considered, with particular reference to corrosion and legibility of marking instructions. If there
is corrosion or the markings are not legible, then the extinguisher should be withdrawn from
service. This is a requirement of the Marine Equipment Directive.

            SERVICING PROCEDURE FOR BRITANNIA MARINE FIRE EXTINGUISHERS
                         CARTRIDGE OPERATED LIQUID MODELS

                          MODEL NO'S: BW9MED, BT9MED, BAF9MED

1. Remove extinguisher from hanging bracket and check security of the bracket, rectify if
   necessary. Check exterior of extinguisher for corrosion or damage, if found withdraw from
   service.

2. Ensure safety pin is in position and the extinguisher has not been completely or partially
   discharged. If the extinguisher has been completely or partially discharged, discontinue
   servicing procedure and commence recharge procedure (ref. RPCOLMED).

3. Weigh extinguisher and compare with weight when first installed. If underweight by 10% of
   contents or more, empty residual content and commence recharge procedure.

4. Ensure instruction label is legible, rectify as necessary. Check for damage/corrosion to
   extinguisher body. If damage/corrosion is found, mark the extinguisher as condemned
   and/or remove from service.

5. Ensure your body/head is not directly over extinguisher. Remove the headcap using the
   nutring spanner (warning: should pressure issue from relief holes allow pressure to escape
   before complete removal of headcap). Do not use blunt instrument, i.e, screw driver etc.

6. Check liquid level ensuring level is below the hanging bracket. Add or remove liquid to
   correct level if necessary.

7. Inspect the interior of the extinguisher for evidence of lifting or cracking of the polythene
   lining, or corrosion. If found , mark as condemned and/or remove from service.

8. Unscrew C02 Cartridge from headcap, clean and check for damage lifting of plastic coating,
   corrosion and age of cartridge (must be changed if older than 10 years from date of
   manufacture), replace if necessary.

9. Checkweigh cartridge against marked weight. Replace if loss of contents is in excess of 10%.

10. Wipe headcap valve clean, check for damage. Remove safety pin and squeeze levers
    ensuring free movement of the firing pin/spindle. Check for blockages and valve shut off by
    blowing through hose whilst opening and closing valve. Ensure nutring relief holes are
    clear.




                                           Page 3 of 10
11. Clean and check condition of headcap 'O' ring, firing pin and spindle, cartridge holder,
    discharge tube and gas tube, if applicable, and filter. Replace if any part shows signs of
    deterioration.

12. Check discharge hose, nozzle and hose clips for wear, cuts or abrasions. Replace if
    necessary.

13. Refit safety pin, service indicator and seal (in accordance with service colour code). Refit
    original or new C02 cartridge.

14. Clean extinguisher neck threads and refit headcap using nutring spanner (do not use blunt
    instrument).

15. Fill in details of service on service label using indelible pen. Clean extinguisher and hang on
    wall bracket.

   inside the cylinder, rectify or replace extinguisher if found).

6. Recharge the extinguisher body with new dry powder, ensuring correct quantity and
   type.Never mix different types of powder as pressure and moisture may develop as a result
   of a chemical reaction.

7. Remove C02 cartridge and discard. Remove gas and syphon tubes, remove balance valve
   and clean the balance valve chamber. (if replacing balance valve holder, ensure locating
   mark lines up with locating lug in the headcap). Remove cartridge holder and firing
   pin/spindle and wipe clean. Replace firing pin/spindle, spring and cartridge holder. Replace
   the cleaned balance valve, ensuring free movement. Replace the syphon tube and gas tube.

MODELS NO'S: BC5MED


Due to the specialised equipment and high pressures involved in the
recharging of C02 extinguishers, only specially trained competent persons
should carry out this procedure.




Recharging should be carried out following the recommendations of BS
6643 part 1.



Always check date of last hydraulic pressure test and do not recharge any
extinguisher that requires a hydraulic pressure test.
