The carbon dioxide unit uses CO2 gas under
high pressure, with a funnel discharge hose
usually swivel mounted. This extinguisher
leaves no residue and does not cause interior
engine harm. To ensure workability, weigh
the unit annually. A 10% max. wt. variance is
allowed.
Another type of liquefied gas is used today in automatic fire
extinguishing systems which is used on select models. The canister gas
is colorless and odorless, heavier than air and sinks to the lower bilge
to extinguish res. Since the year 2000 ingredients for re extinguishers
have changed to a more environmental friendly formula. The canister
needs to be weighed once a year. Automatic re extinguishing systems
feature a dash mount status indicator.
VISUAL DISTRESS SIGNALS
All vessels used on coastal waters, any of the Great Lakes, territorial
seas, and those waters connected directly to them, up to point where a
body of water is less than two miles wide, must have U.S. Coast Guard
approved visual distress signals.
Pyrotechnic Devices
Pyrotechnic visual distress signals must be ready for service and must
be readily accessible. They all display a marking which is the service life,
which must not have expired. A minimum of 3 devices are required
