Question 1672 Deck General

The correct answer is D) 12 years from the latest test date stamped on the cylinder. The small passenger vessel regulations require that the carbon dioxide cylinders of all fixed fire extinguishing systems be retested and remarked whenever a cylinder remains in place on a vessel for 12 years from the latest test date stamped on the cylinder. This is the standard test and retest requirement for such cylinders under the applicable regulations. The other options are incorrect because they do not align with the 12-year retest requirement specified in the regulations for small passenger vessels. A 5-year, 7-year, or 10-year retest period would not be compliant with the applicable rules.
