(d) A person who, within 5 days prior to arrival, has departed from a cholera infected local area or arrives on a healthy vessel or aircraft which has departed from such an area within that time may be placed under surveillance if he has a valid certificate of vaccination against cholera or may be placed in isolation if he does not have such a certificate. The period of isolation or surveillance shall be reckoned from the date of departure of the person, or the vessel or aircraft, from the infected area.

(e) A person who has departed from an infected local area within 5 days prior to arrival and who has symptoms indicative of cholera may be required to submit to a stool examination.

(3) If the complete destruction of rodents cannot be secured because only part of the cargo is due to be unloaded,

a vessel shall not be prevented from unloading that part, but the quarantine officer may apply any measures which he considers necessary to prevent the escape of infected rodents.

(d) If a rodent dead of plague is found on board an aircraft, it shall be deratted. § 61.225 Plague; vessels and aircraft; persons; things.

(a) Persons ill from plague shall be removed and isolated until no longer infectious.

§ 61.247 Application of sanitary meas

ures.

The sanitary measures prescribed by §§ 61.199 and 61.221 through 61.231 of this subpart and such further sanitary measures as may be prescribed by the Governor when necessary to prevent the importation or spread of rodent or vermin vectors of diseases shall be applicable to all vessels docking at Canal Zone facilities.

(a) When in the opinion of the quarantine officer a docking vessel presents a possible source of rodents, the quarantine officer may require the vessel to place, immediately after docking, ratguards in good condition and of a design approved by the Chief, Division of Preventive Medicine and Quarantine, on all mooring lines leading from the vessel to the wharf or to another vessel. The ratguards shall be maintained on the lines while the vessel remains at the wharf, pier or dock. Such rat-guards, placed at a distance between 3 to 5 feet from the vessel, shall be secured in such manner as to prevent rats from passing along the lines and shall be located so as not to overhang the wharf or another vessel.

(b) Rat-guards, to meet the approval of the Chief, Division of Preventive Medicine and Quarantine, shall:

(1) Have a diameter of not less than 3 feet;

(2) Be constructed of metal of sufficient thickness to maintain the shape of the guard (preferably not less than No. 20 gage); and

(3) Be so designed as to fit snugly about the cable or hawser.

(c) A vessel will be required to supply its own rat-guards. A vessel that does not have rat-guards which meet the requirements of this section or does not have a sufficient number of rat-guards for mooring lines, may rent such ratguards from the Terminals Division.

(d) If in the opinion of the quarantine officer a vessel is a possible source of vermin or rodents, the vessel shall be breasted off in such manner that no part of said vessel is nearer than 4 feet to the wharf, pier, or other vessel.

(e) All freight gangways, save-all nets, catch-all nets, cargo chutes, hoses and other gear from vessel to pier or wharf which might serve as a route for the passage of rats to the dock, shall be hoisted when not in use in such manner as to render the passage of rats impossible: Provided, however, That such gear may remain unhoisted for short intervals during the daytime if watchmen from the ship's crew are stationed for the purpose of preventing rats from leaving the vessel by means of such gear.

(f) All gangways shall be well lighted after nightfall and shall be continuously guarded by watchmen from the ship's

Vessels subject to quarantine inspection under the provisions of §§ 61.171 and 61.172 may not enter a port of the Canal Zone to proceed through the Panama Canal or to discharge cargo or land passengers unless a certificate of free pratique or provisional pratique has been issued to the master. When it is desired not to comply with the requirements for a certificate of free or provisional pratique, the vessel is at liberty to return to sea if bound for a foreign port. § 61.262

Free pratique; vessels only.

A certificate of free pratique signifies that the vessel and its master may enter, discharge cargo, and land passengers. § 61.263 Provisional pratique and remand; vessels only.

(a) A certificate of provisional pratique signifies that the vessel may enter, but that additional measures, as specified in the certificate must be taken in connection with proceeding through the Canal, the discharge of cargo, the landing of passengers, or the sanitary condition of the vessel. A certificate of free pratique shall be issued after the additional measures have been completed.

(b) The quarantine officer may remand the vessel to the next port for such additional measures as may be necessary. Vessels arriving at quarantine stations at succeeding ports of call under provisional pratique may, in the discretion of the quarantine officer in charge at such stations, be directed to proceed under provisional pratique to the next succeeding port for completion of quarantine measures.

(c) Failure to comply with additional measures specified in a certificate of provisional pratique constitutes a violation of the rules in this subpart, and the vessel shall become subject to all measures applicable to vessels first arriving at a port of the Canal Zone from a foreign port.

When all necessary quarantine and sanitary measures have been applied to the aircraft and persons and things on board, pursuant to the regulations of this subpart the quarantine officer shall issue a certificate of free pratique, which may be stamped on a copy or copies of the general declaration, including the traveling general declaration, for presentation to the customs officer. Pending compliance with quarantine requirements the quarantine officer may issue a certificate of provisional pratique for the aircraft stating the measures to be carried out. § 61.266

Notification of remands; vessels and aircraft. The quarantine officer remanding a vessel or aircraft to another port in accordance with the provisions of § 61.263 or § 61.265 shall give advance notification to the quarantine officer and customs officer in charge at the port to which the vessel or aircraft is remanded. The notification should be timed to arrive ahead of the vessel or aircraft and should be made by telephone or telegraph as indicated in the case of aircraft. The notification shall give complete information regarding measures carried out at the port effecting the remand and measures required at the port to which the vessel or aircraft is remanded.
