Question 766 Deck Safety

70% to pass

Fixed carbon dioxide extinguishing systems, for machinery spaces that are normally manned, are actuated by one control to open the stop valve in the line leading to the space, and _______________.

A three separate controls to release the CO2
B two separate controls to release the CO2
C the same control releasing the CO2
D a separate control to release the CO2
AI Explanation

The correct answer is D) a separate control to release the CO2. Fixed carbon dioxide extinguishing systems for machinery spaces that are normally manned require a separate control to release the CO2. This is specified in the regulations to provide an additional safeguard against accidental discharge, as the space is occupied during normal operations. The other options are incorrect because they do not align with the regulatory requirement for a separate control to release the CO2, rather than using the same control that opens the stop valve or requiring multiple controls to release the CO2.
