Information Concerning Emergencies Parties shall ensure that such
 continuous radio watches as are deemed practicable and necessary, are maintained on international distress frequencies. A coast radio station receiving any distress call or message shall:
Immediately inform the appropriate rescue co-ordination centre or rescue sub-centre;
Rebroadcast to the extent necessary to inform ships on one or more of the international distress frequencies or on any other appropriate frequency;
Precede such rebroadcasts with the appropriate automatic alarm signals unless this has already been done; and
Take such subsequent action as decided by the competent authority.
Any authority or element of the search and rescue organization having reason to believe that a vessel is in a state of emergency should give as soon as possible all available information to the rescue co-ordination centre or rescue sub-centre concerned.
Rescue co-ordination centres and rescue sub-centres shall, immediately upon receipt of information concerning a vessel in a state of emergency, evaluate such information and determine the phase of emergency in accordance with paragraph 5.2 and the extent of operation required.
 Emergency phases
For operations purposes, the following emergency phases shall be distinguished:
 Uncertainty phase:
When a vessel has been reported overdue at its destination; or when a vessel has failed to make an expected position or safety report.

Alert phase:
When, following the uncertainty phase, attempts to establish contact with the vessel have failed and inquiries addressed to other appropriate sources have been unsuccessful; or
When information has been received indicating that the operating efficiency of a vessel is impaired but not to the extent that a distress situation is likely.
Distress phase:
When positive information is received that a vessel or a person is in grave and imminent danger and in need of immediate assistance; or
When, following the alert phase, further unsuccessful attempts to establish contact with the vessel and more widespread unsuccessful inquiries point to the probability that the vessel is in distress; or
When information is received which indicates that the operating efficiency of a vessel has been impaired to the extent that a distress situation is likely.

Procedures for rescue co- ordination centres and rescue sub-centres during emergency phases
1. Upon the declaration of the uncertainty phase, the rescue co-ordination centre or rescue sub-centre, as appropriate, shall initiate inquiries in order to determine the safety of the vessel or shall declare the alert phase.
2. Upon the declaration of the alert phase, the rescue co-ordination centre or rescue sub-centre, as appropriate, shall extend the inquiries for the missing vessel, alert appropriate search and rescue services and initiate such action, as described in paragraph 5.3.3, as is necessary in the light of the circumstances of the particular case.
3. Upon the declaration of the distress phase, the rescue co-ordination centre or rescue sub-centre, as appropriate, shall:
Initiate action in accordance with the arrangements set out in paragraph
Where appropriate, estimate the degree of uncertainty of the vessel’s position and determine the extent of any area to be searched;
Notify the owner of the vessel or his agent if possible and keep him informed of developments;
Notify other rescue co-ordination centres or rescue sub-centres, the help of which seems likely to be required or which may be concerned in the operation;
Request at an early stage any help which might be available from aircraft, vessels or services not specifically included in the search and rescue organization, considering that, in the majority of distress situations in ocean areas, other vessels in the vicinity are important elements for search and rescue operations;
Draw up a broad plan for the conduct of the operations from the information available and communicate such plan to the authorities designated
Amend as necessary in the light of circumstances the guidance already given
Notify the consular or diplomatic authorities concerned or, if the incident involves a refugee or displaced person, the office of the competent international organization;
Notify accident investigation authorities as appropriate; and
Notify any aircraft, vessel or other services mentioned in consultation with the authorities designated when their assistance is no longer required.
Initiation of search and rescue operations in respect of a vessel whose position is unknown
In the event of an emergency phase being declared in respect of a vessel whose position is unknown, the following shall apply:
1. when a rescue co-ordination centre or rescue sub-centre is notified of the existence of an emergency phase and is unaware of other centres taking appropriate action, it shall assume responsibility for initiating suitable action and confer with neighbouring centres with the objective of designating one centre to assume responsibility forthwith;
2. unless otherwise decided by agreement between the centres concerned, the centre to be designated shall be the centre responsible for the area in which the vessel was according to its last reported position; and
3. after the declaration of the distress phase, the centre co-ordinating the search and rescue operations shall, if necessary, inform other appropriate centres of all the circumstances of the state of emergency and of all subsequent developments.
Passing information to vessels in respect of which an emergency phase has been declared
Whenever applicable, the rescue co-ordination centre or rescue sub-centre responsible for search and rescue operations shall be responsible for passing to the vessel for which an emergency phase has been declared, information on the search and rescue operation it has initiated.

Co-ordination when two or  more parties are involved Where the conduct of operations over the entire search and rescue region is that responsibility of more than one Party, each Party shall take appropriate action when so requested by the rescue co-ordination centre of the region.
Termination and suspension of search and rescue operations
Uncertainty phase and alert phase:
When during an uncertainty phase or an alert phase a rescue co-ordination centre or rescue sub-centre, as appropriate, is informed that the emergency no longer exists, it shall so inform any authority, unit or service which has been activated or notified.

Distress phase:
When during a distress phase a rescue co-ordination centre or rescue sub-centre, as appropriate, is informed by the vessel in distress or other appropriate sources that the emergency no longer exists, it shall take the necessary action to terminate the search and rescue operations and to inform any authority, unit or service which has been activated or notified.
If during a distress phase it has been determined that the search should be discontinued the rescue co-ordination centre or rescue sub-centre, as appropriate, shall suspend the search and rescue operations and so inform any authority, unit or service which has been activated or notified. Information subsequently received shall be evaluated and search and rescue operations resumed when justified on the basis of such information.
If during a distress phase it has been determined that further search would be of no avail, the rescue co-ordination centre or rescue sub-centre, as appropriate, shall terminate the search and rescue operations and so inform any authority, unit or service which has been activated or notified.
On-scene co-ordination of search and rescue activities
The activities of units engaged in search and rescue operations, whether they be rescue units or other assisting units, shall be co-ordinated to ensure the most effective results.
Designation of on-scene commander and his responsibilities
When rescue units are about to engage in search and rescue operations, one of them should be designated on-scene commander as early as practicable and preferably before arrival within the specified search area.
The appropriate rescue co-ordination centre or rescue sub-centre should designate an on-scene commander. If this is not practicable, the units involved should designate by mutual agreement an on-scene commander.
Until such time as an on-scene commander has been designated, the first rescue unit arriving at the scene of action should automatically assume the duties and responsibilities of an on-scene commander.
An on-scene commander shall be responsible for the following tasks when these have not been performed by the responsible rescue co-ordination centre or rescue sub-centre, as appropriate:
Determining the probable position of the object of the search, the probable margin of error in this position, and the search area;
Making arrangements for the separation for safety purposes of units engaged in the search;
Designating appropriate search patterns for the units participating in the search and assigning search areas to units or groups of units;
Designating appropriate units to effect rescue when the object of the search is located; and
Co-ordinating on-scene search and rescue communications.

An on-scene commander shall also be responsible for the following:
Making periodic reports to the rescue co-ordination centre or rescue sub-centre which is co-ordinating the search and rescue operations; and
Reporting the number and the names of survivors to the rescue co-ordination centre or rescue sub-centre which is co-ordinating the search and rescue operations, providing the centre with the names and destinations of units with survivors aboard, reporting which survivors are in each unit and requesting additional assistance from the centre when necessary, for example, medical evacuation of seriously injured survivors.

Designation of co-ordinator surface search and his responsibilities If rescue units (including warships) are not available to assume the duties of an on-scene commander but a number of merchant vessels or other vessels are participating in the search and rescue operations, one of them should be designated by mutual agreement as co-ordinator surface search.
The co-ordinator surface search should be designated as early as practicable and preferably before arrival within the specified search area.
The co-ordinator surface search should be responsible for as many of the tasks listed in paragraphs 5.7.4 and 5.7.5 as the vessel is capable of performing.
 Initial action
Any unit receiving information of a distress incident shall take whatever immediate action to assist as is within its capability or shall alert other units which might be able to assist and shall notify the rescue co-ordination centre or rescue sub-centre in whose area the incident has occurred.
Search areas
Search areas determined may be altered as appropriate by the on-scene commander or the co-ordinator surface search, who should notify the rescue co-ordination centre or rescue sub-centre of his action and his reasons for doing so.
Search patterns
Search patterns designated may be changed to other patterns if considered necessary by the on-scene commander or the co-ordinator surface search, who should notify the rescue co-ordination centre or rescue sub-centre of his action and his reasons for doing so.
Search successful
When the search has been successful the on-scene commander or the co-ordinator surface search should direct the most suitably equipped units to conduct the rescue or to provide other necessary assistance.
Where appropriate the units conducting the rescue should notify the on-scene commander or the co-ordinator surface search of the number and names of survivors aboard, whether all personnel have been accounted for and whether additional assistance is required, for example, medical evacuations, and the destination of the units.
The on-scene commander or the co-ordinator surface search should immediately notify the rescue co-ordination centre or rescue sub-centre when the search has been successful.
Search unsuccessful
The search should only be terminated when there is no longer any reasonable hope of rescuing survivors.
The rescue co-ordination centre or rescue sub-centre co-ordinating the search and rescue operations should normally be responsible for terminating the search.
In remote ocean areas not under the responsibility of a rescue co-ordination centre or where the responsible centre is not in a position to co-ordinate the search and rescue operations, the on-scene commander or the co-ordinator surface search may take responsibility for terminating the search.
