132.230—Spare charges.
(a)
Except as provided by paragraph (b) or (c) of this section, each vessel must carry spare charges for 50 percent of the portable fire extinguishers required by § 132.220 of this subpart.
(b)
Rather than comply with paragraph (a) of this section, a vessel may carry one extra portable extinguisher of the same classification.
(c)
If extinguishers of a particular classification cannot be readily recharged by crew members, a vessel must—rather than comply with paragraph (a) of this section—carry one more extinguisher of that classification.
(d)
Each spare charge must be packaged so as to minimize the hazards to personnel recharging the extinguishers.
