•
There is no obvious physical damage, corrosion, leakage or
clogged nozzles.
•
Weigh extinguishers annually to assure that the minimum weight is
as stated on the extinguisher label.
Fire extinguishers that do not satisfy the above requirements or that have
been partially emptied must be replaced or taken to a qualified fire
extinguisher servicing company for recharge.
The pressure gauge alone is not an accurate indicator that Halon
extinguishers are full. The weight of the units should be checked regularly.
It is recommended that portable extinguishers be mounted in a readily
accessible position.
9.10. VISUAL DISTRESS SIGNALS
Please check with local authorities for the required visual distress signals.
Even if non required in your region, it is advisable to carry them on board.
Following is general information about available Visual Distress Signals.
9.11. PYROTECHNIC DEVICES
Pyrotechnic Visual Distress Signals must be approved, in serviceable
condition, and readily accessible.
•
They are marked with an expiration date. Expired signals may be
carried as extra equipment, but can not be counted toward
meeting the visual distress signal requirement, since they may be
unreliable.
•
If pyrotechnic devices are selected a minimum of three are
required. That is, three signals for day use and three signals for
night. Some pyrotechnic signals meet both day and night use
requirements.
•
Pyrotechnic devices should be stored in a cool, dry location, if
possible.
NORTHSTAR MANUAL
•
A watertight container painted red or orange and prominently
marked "DISTRESS SIGNALS" or "FLARES" is recommended.
Examples of Pyrotechnic Visual Distress Signals and associated devices
include:
•
Pyrotechnic red flares, hand-held or aerial.
•
Pyrotechnic orange smoke, hand-held or floating.
•
Launchers for aerial red meteors or parachute flares.
Each of these devices has a different operating (burning) time. Check the
label to see how long each pyrotechnic device will actually be illuminated.
This will allow you to select a warning device better suited to the conditions
where your boat will operate.
9.11.A. NON-PYROTECHNIC DEVICES
Non-Pyrotechnic Visual Distress Signals must be in serviceable condition,
readily accessible, and certified by the manufacturer as complying current
requirements.
They include:
Orange distress flag
•
Day signal only.
•
Most distinctive when attached and waved on a paddle, boathook,
or flown from a mast.
•
May also be incorporated as part of devices designed to attract
attention in an emergency, such as balloons, kites, or floating
streamers.
