Check the state of charge of each fire extinguisher at least once every 12 months, and in any case before each journey at sea, by means of the installed pressure gauge. The fire extinguisher is correctly charged when the weight value is as stated on the fire extinguisher’s tag, and the charge indicator on the pressure gauge is in the green area.
If they are found to be discharged or insufficiently charged, or at least every 10 years, have qualified technicians:

• Check the condition of the container (cylinder);
• Refill the extinguishing medium;
• Carry out a hydrostatic test.
