(d) All hand portable fire extinguishers and semiportable fire extinguishing systems shall have permanently attached thereto a metallic
name plate giving the name of the
item, the rated capacity in gallons,
quarts, or pounds, the name and address of the person or firm for whom
approved, and the identifying mark of
the actual manufacturer.
(e) Vaporizing-liquid type fire extinguishers containing carbon tetrachloride or chlorobromomethane or
other toxic vaporizing liquids are not

(g) The use of dry chemical, stored
pressure, fire extinguishers not fitted

and other vessels so long as such extinguishers are maintained in good and
serviceable condition. The following
maintenance and inspections are required for such extinguishers:
(1) When the date on the inspection
record tag on the extinguishers shows
that 6 months have elapsed since last
weight check ashore, then such extinguisher is no longer accepted as meeting required maintenance conditions
until reweighed ashore and found to be
in a serviceable condition and within
required weight conditions.
(2) If the weight of the container is 1⁄4
ounce less than that stamped on container, it shall be serviced.
(3) If the outer seal or seals (which
indicate tampering or use when broken) are not intact, the boarding officer or marine inspector will inspect
such extinguisher to see that the frangible disc in neck of the container is
intact; and if such disc is not intact,
the container shall be serviced.
(4) If there is evidence of damage,
use, or leakage, such as dry chemical

powder observed in the nozzle or elsewhere on the extinguisher, the container shall be replaced with a new one
and the extinguisher properly serviced
or the extinguisher replaced with another approved extinguisher.
(h) The dry chemical, stored pressure, fire extinguishers without pressure gauges or indicating devices manufactured after January 1, 1965, shall
not be labeled with the marine type
label bed in § 162.028–4 of this title nor
shall such extinguishers manufactured
after January 1, 1965, be carried on
board motorboats or other vessels as
required equipment.
