Any automatic sprinkler, fire detection and fire alarm system shall be capable of immediate operation at all times and no action by the crew shall be necessary to set it in operation. Each section of sprinklers shall include means for giving a visual and audible alarm automatically whenever any sprinkler comes into operation. Sprinklers shall be grouped into separate sections, each of which shall contain not more than 200 sprinklers. Each section shall be capable of being isolated by one stop valve only. A gauge indicating the pressure in the system shall be provided at each section stop valve and a central station. The sprinklers shall be resistant to corrosion by marine atmosphere. In accommodation and service spaces the sprinklers shall come into operation within the temperature range from 68°C to 79°C. A list or plan shall be displayed at each unit and suitable instructions for testing and maintenance shall be available. Sprinklers shall be placed in an overhead position to maintain an average application rate of not less than 5 l/m²/min over the area covered by the sprinklers.
According to the passage, it isn‟t true that;
a) The sprinklers can be affected by marine atmosphere.
b) They will be in an overhead position to maintain the average application.
c) The pressure in the system is displayed by a pressure gauge
d) Sprinkler system is used either fixed or mobile on board.
e) The system shall be divided into sections.
What statement is true regarding deck machinery?
a) Deck machinery is used only for cargo handling
b) Deck machinery can be driven by hydraulic, electric or steam force
c) Tankers mostly use electric-driven deck machinery
d) Navigation and the conduct of ship mostly depend on deck machinery
e) Deck machinery is controlled from the engine room
