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)?
