Float-free enclosure

6.2.1

Siting

The enclosure should be mounted upright against a vertical bulkhead.
Alternatively, it may be mounted horizontally on a flat surface such as a cabin
roof. No other orientations are recommended.
It is critical that you choose a location suitable for automatic deployment. The
EPIRB should be sited so that it can float free regardless of the attitude of the
vessel during or following capsize. An expanse of flat surface is required to
allow the enclosure lid to eject. The wheelhouse top is a favoured position,
although an alternative location should be found if rigging, masts or existing
equipment could affect automatic activation. The EPIRB should also be
accessible so that it can be taken to the life raft if it becomes necessary to
abandon ship.
If the EPIRB is placed on one side of the vessel, or immediately behind the
wheelhouse then the likelihood of correct deployment is much reduced.
Use the recommendations below to choose a suitable mounting position:
DO:

Mount on the outside of the vessel's structure as high as possible.

Mount close to the vessel's navigation position.

Consider ease of access in an emergency.
AVOID:

Positions with insufficient space for lid ejection and maintenance.

Positions within 1 m of any compass equipment.

Positions within 2 m of any radar antenna.

Positions with high levels of vibration.

Direct impact from waves.

Siting where damage is likely.

Siting close to exhaust fumes, chemical and oil sources.
