According to uninspected vessel regulations what is NOT listed on the metallic name plate required to be attached to hand portable fire extinguishers?

Correct Answer: Option C — The hydrostatic test date of the cylinder

While 46 CFR requires manufacturer nameplates on portable extinguishers to display the item name, manufacturer identification, and rated capacity, hydrostatic test dates are stamped or tagged separately during periodic servicing rather than permanently engraved on the standard metallic nameplate.
