Powered Ventilation
FEDERAL LAW
183.610 - Powered ventilation system
(e) More than one exhaust blower may be
used in combination to meet the requirements of this
section. |
This section authorizes the use of more than
one blower in a compartment in order to provide the required
rated blower capacity and the required blower system output.
Using two or more blowers in combination means they must be
energized together. The use of one or more blowers is discussed
in a previous section.
FEDERAL LAW
183.610 - Powered ventilation system
(f) Each boat that is required to have
an exhaust blower must have a label that:
(1) Is located as close as practicable
to each ignition switch;
(2) Is in plain view of the operator; and
(3) Has at least the following information:
WARNING
GASOLINE VAPORS CAN EXPLODE. BEFORE STARTING ENGINE
OPERATE BLOWER FOR 4 MINUTES AND CHECK ENGINE
COMPARTMENT BILGE FOR GASOLINE VAPORS. |
|
If a blower is required on a boat, there must
be a label affixed to the boat. The label must be located
so that the following requirements are satisfied:
- It must be near the ignition switch(es),
and
- It must be able to be seen by an operator
who is in a normal position to operate the ignition switch(es)
Examples of Label Locations
- If the ignition switch(es) is (are) on the
side of a console then the label(s) should be on the top
visible surface of the console above the switch(es)
- If two ignition switches are located next
to each other, then one label serves both switches.
- If two or more ignition switches are provided
for one engine as might be the case with a boat with two
steering stations then a label must be affixed to each location.
A boat with a flying bridge has two steering stations.
- If a boat is equipped with auxiliary gasoline
powered equipment such as a generator, then the ignition
switch location for this equipment must have a label.
- If the switch is located in a position which
may not be readily visible from the helm; i.e. on the side
of a console, two labels are needed. Locate one label near
the switch and the other on the console in a location visible
from the helm, near the throttle.
The label must contain the information specified
in the regulation. It does not have to be stated in the exact
words used but it must deliver the same message.
An acceptable label consists of the following
four elements:
1. The signal word
|
WARNING |
| 2. The hazard |
GASOLINE VAPORS |
3. Consequences of the hazard
|
CAN EXPLODE |
| 4. Action required |
BEFORE STARTING ENGINE OPERATE BLOWER 4 MINUTES |
Additional information my be included on the
label.
The following is an example of a prepared label:
WARNING
GASOLINE VAPORS CAN EXPLODE.
BEFORE STARTING ENGINE
CHECK ENGINE COMPARTMENT FOR GASOLINE OR VAPORS
AND OPERATE BLOWER FOR 4 MINUTES |
TO COMPLY WITH THE LAW
- Is a blower required?
If YES, then:
- Is there a label installed?
If YES, then:
- Is there a label near each engine and
generator ignition switch, and is the label located
so that the boat operator can read it?
- Does the label contain the information
required by 183.610(f)(3)?
