The correct answer is B) Each fireman's outfit shall contain a flame safety lamp of an approved type. This is correct because the regulations for cargo vessels require that each fireman's outfit contain a flame safety lamp of an approved type. This is a safety requirement to allow the fireman to safely navigate and perform their duties in a fire or other emergency situation on board the vessel. The other options are incorrect - option A is incorrect because the regulations require that the fireman's outfits be stored in separate locations, not the same location. Option C is incorrect because the regulations require a fresh-air breathing apparatus, not a full self-contained breathing apparatus. Option D is incorrect because only option B is the fully correct statement.
