The mass of all portable fire extinguishers shall not exceed 23 kg and they shall have a fire-extinguishing capability at least equivalent to that of a 9 / fluid extinguisher.
The construction of an extinguisher should be designed and manufactured for simple and rapid operation, and ease of handling.
Extinguishers should be manufactured to a national or other recognized standard which includes a requirement that the body, and all other parts subject to internal pressure, be tested to a pressure above the maximum expected during the service life of the extinguisher. In the design of components, selection of materials and determination of maximum filling ratios and densities, consideration should be given to the temperature extremes to which extinguishers may be exposed on board ships.
The materials of construction of exposed parts and adjoining dissimilar metals should be carefully selected to function properly in the marine environment.
Construction, performance and fire-extinguishing test specifications should be to the satisfaction of the Administration.
Each extinguisher should be clearly marked with the following minimum information:
.1 name of the manufacturer;
.2 types of fire for which the extinguisher is suitable;
.3 type and quantity of extinguishing medium;
.4 approval details;
.5 instructions for use and recharge (it is recommended that operating instructions be given in pictorial form),
.6 year of manufacture;
.7 temperature range over which the extinguisher will operate satisfactorily;
.8 test pressure
Extinguishers should be subject to periodical inspections and maintenance in accordance with the manufacturer's instructions. The periods between such inspections and maintenance should not exceed the period between safety equipment surveys.
Records of inspections should be maintained. The records should show the date of inspection, the type of maintenance carried out, and whether or not a pressure test was performed.
Instructions for recharging extinguishers should be supplied by the manufacturer and be available for use on board.
