In addition to these documents, a copy of the ship’s cargo manifest shall also be forwarded to the Deputy Port Conservator and Traffic Manager and Container Terminal Manager to enable them to gather information regarding transit cargo of dangerous/hazardous goods containers carried by each ship.

(2) Exports: – The intention to export dangerous/hazardous cargoes through containers shall be advised to the Port Authority prior to their delivery to the Berth at least 48 hours in advance and permission obtained from the Deputy Port Conservator and Traffic Manager before the dangerous/hazardous cargo to be stuffed in containers are moved into the Port.

(3) Transit:– Same prohibitions and restrictions as applicable in respect of dangerous/hazardous cargo for loading or unloading within the Indian Ports shall be applicable for cargo in transit.

Any container ship carrying container containing dangerous/hazardous cargo on board shall be berthed only when permission to berth is granted by the Port Authority at the designated berth.

9.     The port authorities shall stack the dangerous/hazardous cargo containers in either of the following:
(a) Stack the containers separately in a specially designated area which has been constructed for storage of dangerous/hazardous cargo and provided with fire fighting arrangements.
(b) Stack the containers in the Parking yard itself by providing proper segregation as per IMDG Code. (The segregation table is given in the Appendix ‘A’ suggested method of segregation as per IMDG or IMCO Segregation Code in a Container Parking Yard with tyremounted Transfer Cranes is shown in the Appendix-‘B’).

The Port Authorities shall devise a suitable segregation plan as regards to the classification of the cargo and type of handing in the Terminal.



(1).The Port Authority shall designate container depot/container freight station suitable to handle    dangerous/hazardous cargo. The Stacking of containers shall be in accordance with Para 9 above. The stuffing or destuffing operation shall commence only after obtaining clearance from the Deputy Port Conservator and Traffic Manager. The stuffing and destuffingoperation shall follow strictly the IMO Guidelines for the packing of dangerous/hazardous cargo in freight Container and shall comply with Classes 12 & 13 of IMDG Code (Appendix ‘C’).

In case stuffing or destuffing is done in an area in the vicinity of stackyard, a minimum distance of 30 meters around shall be observed.

(2).Before stuffing:- (1) Containers into which dangerous cargo are to be stuffed shall be examined visually for damage and if there is evidence of material damage, the container shall not be packed. Container shall be clean, dry and fit for use. Irrelevant dangerous cargo labels shall be removed or masked over before stuffing begins.

(2) Information shall be provided by the Shipper about hazardous properties of the dangerous cargo to be handled. The shipper shall also ensure that dangerous cargoes are stuffed, marked and labelled in accordance with the IMDG Code.  Dangerous cargo shall not be handled unless packaged, marked and labelled in accordance with these regulations.

(3). Dangerous cargo shall only be handled, stuffed and secured under direct and identifiable supervision of a responsible person deputed by the Consignor or the Consignee as the case may be who is  familiar with the risks involved and know which emergency measure should be taken.  he shall also ensure that any necessary protective equipment is available.

(4). Smoking shall be prohibited while work is going on.

(5). Suitable fire precaution measure shall be taken.

(6). Packages shall be examined and any found to be damaged, leaking or sifting shall not be stuffed into a container.  Packages showing evidence of staining etc., shall not be packed into a container without first determining that it is safe and acceptable to do so.  Water or other matter adhering to packages shall b e removed before packing into a container.

(7). If cargoes are palletized or otherwise unitized they shall be compact and secured in a manner unlikely to damage the individual packages comprising the unit load.  The materials used to band the unit load together shall be compatible with the substances unitized and retain their efficiency when exposed to moisture, extremes of temperature and sunlight, incompatible substances.  Guidance of both a general and particular nature on this matter may be found in the IMDG Code.

NOTE : It is also possible that in some instances goods of the same class shall not be stuffed into the same container as they are incompatible. For example, Peroxides and permanganates are both oxidizing agents (class 5.1). However, they may interact dangerously in the event of an accident.

(8).  In case where electric power supplied is used for any equipment or machinery in the area where containers are stacked or stuffing and destuffing is carried out, the electric supply systems in the machinery shall be of a type which will not cause any spark likely to cause hazard.

(9).  A container intended to carry dangerous cargo under temperature control shall be inspected and operated to ensure that the machinery is in proper working order before the shipment is made.   A record of the inspection shall be maintained.

(3).Stuffing and securing:- Special care shall be taken during handling to ensure that the packages or receptacles are not damaged:

(1) If a package containing dangerous cargo is damaged during handling so that the  contents leak out, the immediate areas shall be evacuated until the hazard potential can be assessed. The damaged packages shall not be transported.

(2) No re-packing shall be done within the Port premises. If leakage from dangerous cargo likely to cause any explosion, spontaneous combustion, poisoning or similar danger, personnel shall immediately be moved to a safe place and the emergency response organisation (e.g. the fire service) shall be notified.

(3) Dangerous goods shall not be stuffed in the same container which ensures that dangerous cargoes are stuffed marked and labelled in accordance with IMDG Code. Dangerous cargo shall not be handled unless packaged, marked and labeled in accordance with these regulations.

(4).Dangerous goods which may damage by taint odour or contamination to other  products shall not be stuffed in the same container as goods susceptible to such damage.

(5).When dangerous cargo, particularly those of Class 6.1 (poison) and class 8 (Corrosives) are handled, consumption in any form of food or drink shall be prohibited.

(6). Special packing instructions detailed on individual packages or otherwise available must be strictly observed (e.g.) Goods Marked “protect from frost” shall be stowed away from the walls of the container.

Goods marked “this way up” shall be packed accordingly. When dangerous goods consignment forms only part of the load of a container, it shall preferably be stuffed as to be accessible from the doors of the container.


(1) The containers shall sealed prior to despatch. However, they shall not be locked unless specifically required are agreed to by the container operator. In such cases a key shall be readily available at all times.

(2) Containers in which dangerous goods are stuffed shall bear IMCO Dangerous Goods Code Class Labels (Placards) not less than 250 mm x 250 size. Except where not required by IMDG Code there shall be at least four such lables (placards) placed externally in conspicuous places, one on each side and one on each end. Labels for the sides of the container shall affixed in such position that they are not obscured when the container doors are opened.

(3) The container shall also bear externally the correct technical name of each of the dangerous substances packed therein.

(4) Additional labels as may be required by rail and road transport authorities shall be provided.

Those responsible for the stuffing of the dangerous cargo into a container shall provide a “Container Stuffing Certificate” certifying that this has been properly carried out and embodying the following provisions:
(1) That the container was clean, dry and apparently fit to receive the goods.
(2) No incompatible goods have been stuffed in the container.
(3) All packages have been externally inspected for damage and only dry, sound packages packed.
(4) All packages have been properly stuffed in the container and secured and suitable securing materials used.
(5) The container and packages are properly marked and labelled.
(6) The dangerous cargoes in the container are those for which acceptance has been specifically obtained with the shipment in question.
(7) The consignor of the dangerous cargoes has in each case issued a dangerous cargoes declaration as to nature of the hazard and that the cargoes are suitable packaged for transport by sea.
(8) The Container Stuffing Certificate shall be forwarded with the container to be available at the time of loading on boardship.
(9) The permission of the Deputy Port Conservator has been obtained for stuffing the cargo.


Containers containing dangerous cargo shall destuffed with care, always bearing in mind that the cargo may have been damaged in transit. Before the doors are opened, this possibility shall be borne in mind in relation to the properties of the cargo. For example, depending on the contents of the container, there may exist the possibility that leakage has caused an unsafe concentration of toxic, inflammable or explosive vapour, or to have produced an oxygen enriched (or depleted) atmosphere. If there is evidence that damage has occurred and such a condition exists, expert advice must be sought before commencing to destuff the containers.
(1) Any container which carried dangerous cargo particularly toxic products shall be ventilated before unpacking commences, that is the door shall be kept open for an adequate period.

(2) After a container containing dangerous goods has been unpacked, particular care must be taken to ensure that no hazard remains. This may entail special cleaning, particularly if toxic spillage has occurred or is suspected. When satisfied that a container offers no hazard, the dangerous goods labels shall be removed.
(3) If any container shows signs of heat it shall be removed to a safe place and fire services immediately notified. Care shall be taken to see that any fire fighting methods to be used are suitable for the cargo in question.
(4) Attention is drawn to the fact that the consignee is normally obliged to return the container, after discharging clean and suitable for the transport of every kind of cargo. This applies especially when poisonous, dangerous or obnoxious cargo has been transported.


(1).Notification of import of dangerous cargo must be given  to the concerned Port Authority by the operator prior to the arrival of the container within the Port.

(2).The import cargo documents must be endorsed with a “Dangerous goods” stamp by the operator or the person responsible for preparing the documents before the container is discharged.

(3).Dangerous cargo containers shall be destuffed with care always bearing in mind that the cargo may have been damaged is transit. Before the doors are opened, this possibility shall be borne in mind in relation to the properties of the cargo. If there is evidence that such damage has occurred, expert advice must be sought before commencing destuffing of the container.

(4).As cargo is destuffed and checked, it must be separated to its class and placed in the correct storage area. Any discrepancy in respect of marks, labels or type of packaging must be reported to the Supervisor and the Operating Company shall be advised at the earliest opportunity.

(5).Areas for the storage of the various classes shall be clearly defined and where possible there shall be an outside storage provided the packaging is suitable. In any event dangerous goods shall be set apart from the general cargo within the transit shed.

(6).Removal of import dangerous cargo must be effected immediately.

(7).All dangerous cargo labels shall be removed as soon as the container can be declared non-hazardous.

(8).Total quantity dangerous cargo in a designated are shall not exceed five container loads.


(1).Special fire fighting provisions shall be made in the designated areas where dangerous/hazardous cargo containers are kept. These shall include:

(2).The provision of all fire fighting equipment as required by national or local regulations in properly maintained and fully operational condition.

(3).The provision of clear information as to emergency routines to be followed and a regular practice of such routines.

(4).Good liaison between the container base and the local fire brigade. The means to call the fire service shall be readily available at all times.

(5).Good housekeeping and cleanliness. For example patches of oil mixed with sawdust are a potential source of ignition, heaps of rubbish can be readily ignited, piles of dunnage can assist in the rapid spread of fire etc.

(6).Proper care shall be taken to minimise sources of ignition such as smoking, unprotected or ill maintained electrical installations or repair equipment.

(7).Proper care of machinery and with its operations particularly where refueling is concerned.

(8).Clear access to fire appliances within the premises shall be maintained and a route kept clear all the times to allow rapid access for emergency vehicles from outside.

Copy of Section 12 and extract of Section 13 of
International Maritime Dangerous Goods code


12.1.1 The recommendations of this text apply to containers in which packages of dangerous goods are loaded.

12.1.2. In container traffic a number of small packages is enclosed for transit in a large bag fitted with doors and lifting points. The size and construction of the container may vary with the trade in which it is employed. Many containers  are the demountable bodies of road of rail vehicles.

12.1.3. Containers used for the carriage of dangerous goods should be of adequate strength to resist the possible stresses imposed by the conditions of the services in which they are employed.

12.1.4. Dry dangerous goods in bulk may be carried in containers specially approved for this purpose by the competent authorities.

12.1 Permitted Shipments:

12.2.1 Dangerous goods should only be transported in containers when they are packed as recommended in this code except as provided in Section 12.1.4.

12.2.2 Containers in which dangerous goods are loaded should not be transported on board passenger vessels unless such gods are specifically permitted  by this Code to be so transported.

12.2.3. A dangerous substance should not be stewed in the same container  with any other substance with which it is deemed incompatible by this code unless the requirement for segregating those substances is not more stringent than “away from” (as defined in Section 15.8) and such segregation within the container can be assured during transport.

12.3. Container Certification:

12.3.1. The requirements set out in section 9 of the general Introduction to this Code with respect to the documentation of packaged dangerous goods should be met.

12.3.2. Containers in which dangerous goods are loaded should be examined externally for damage, signs of leakage or shifting of contents. Any container found to be damaged leaking or shifting should not be accepted for shipment until repairs have been effected and or damaged receptacles removed.

12.4 Marking and Labelling:

12.4.1 Containers in which dangerous goods are loaded should bear labels as specified for each class in this code, affixed in the outside, in a conspicuous place.

12.4.2 The special dangerous goods list or manifest (required by Regulation 5 (c) of chapter VII of the Convention) should indicate clearly those containers in which dangerous goods are loaded and their location in the ship. The total quality of each dangerous substance in addition to the description as required under the aboveRegulation, should also be shown also in the list on manifest.

12.4.3. Individual packages loaded in a container are exempt from the labelling requirements but the use of dangerous goods labels on such packages is recommended in case they need to be quickly identified in an emergency.

12.5. Stowage of Containers:

12.5.1 Containers in which dangerous goods are loaded should generally be carried and segregated in accordance with the stowage requirements laid down in this code for such goods e.g. if dangerous goods which are required to be stowed on deck are carried in a container, then that container must also be stowed on deck.

12.5.2. Containers in which dangerous goods are loaded should also be generally segregated in accordance with this code in those cases where such segregation is not possible by virtue of the construction of ship (e.g. where there are no intervening bulk heads on a container deck) alternative segregation arrangements may be accepted provided the competent authority is satisfied that an equivalent degree of safety is thereby assured.

12.5.3 Packages of dangerous substances and any other goods within the containers should be adequately braced and secured for the voyage. The packages should be loaded in such a way that there will be a minimum likelihood of damage to fittings during transportation. Such fittings on packages should be adequately protected.

12.5.4 Containers equipped with refrigerating or heating equipment, and which give rise to a toxic and or inflammable hazard should be stowed on deck, they may be stowed and operated under deck provided that adequate ventilation and other safety precautions to the satisfaction of the competent authority, are observed.

Section 13-portable tanks;

13.1. Applicability and Definitions:

13.1.1. Applicability: The recommendations of this Section apply to portable tanks (as defined in fitted with pressure relief devices, intended for the carriage of dangerous liquids. Attention is drawn to the fact that no provisions have been included in respect of any additional fire-fighting and protection measures or other special equipment which may be necessary on ships carrying portable tanks. Portable tanks of types other than those covered by this section may be considered for the carriage of dangerous liquids under special conditions to be prescribed by the competent authority. exceptional hazards exist for an individual substance, additional requirements may be specified by the competent authority.

13.1.2. For the purpose of this section a portable tank means a tank having a capacity of 450 litters(100 gallons) or above for the transport bulk liquids with a vapourpressure of less than 3kp/Cm2-Absolute-43 psia ) at a temperature of 50° C (122° F). The tank should not be permanently secured on board the ship and its contents should to be loaded or discharged while the tank remained on board. The loaded tank should be capable of being lifted on and off the ship. Maximum allowable working pressure is the maximum gauge pressure permissible at the top of a tank in its operating position. This pressure is based on calculations for every element of the vessel using nominal thickness exclusive of:

(a) Allowances for corrosion, and

(b)Thickness required for loadings other than pressure. Start-to-discharge pressure is the value of static pressure below which no bubbling occurs when a pressure relief valve is tested by means of air under a specified water seal on the outlet. containment pressure is the sum  of the vapour pressure in kp/Cm2(psig) at a reference temperature at the liquid surface as specified by the competent authorities concerned, plus the effect on total pressure of the partial pressure contributed by the presence of air and other gases in the ullage space, the liquids expansions as determined by the bulk means reference temperature and the effect of the solubility of air and other gases in the liquid, plus a minimum dynamic pressure of 0.35 kp/Cm2 (5 psig). In no case should the total contentment pressure be taken to less than 1.75kp/Cm2 (25 psig). where no acceptable data for solubility exists, it should be neglected.

13.11.Testing and Inspection of portable Tanks:

13.11.1. Such tests and inspections as the competent authority may require should be carried out during construction.

13.11.2 Every portable tank, and all piping, valves and other accessories thereof which are subject to the pressure of the tank contents, except pressure relief devices, should be tested by complete filling (including domes, if any)with water or other liquid having a similar density and applying a pressure of not less than 1and half times the maximum allowable working pressure. The details of the test should be as prescribed by the competent authority.

While under pressure, the tank should be inspected for leakage, corroded areas, dents or other conditions which indicate weakness that might render the tanks unsafe for transportation service, and it should not be placed in or or returned to service if any evidence of such unsafe conditions is discovered until the tank etc. has been repaired and the test repeated and passed successfully.

13.11.3 A tank should not be accepted for shipment unless the pressure relieving devices have been examined by a competent person in the previous six months. A visual  and external examination may suffice. However, for those cargoes which tend to render the devices in operative, the competent authority may require more frequent examination.

13.11.4. Tanks and their fitting should be inspected internally and externally with sufficient frequency and with due regard to the contents carried, but in no case at intervals greater than two and a half years under conditions prescribed by the competent authority.

13.11.5. All pressure relief valves should be retested and inspected at intervals of not more than 2 ½ years, with due regard to the contents carried and under conditions prescribed by the competent authority.

13.11.6 Tanks should be retested hydraulically at intervals of not more than five years under conditions prescribed by competent authority. Other types of retest may be permitted, exceptionally, as prescribed by the competent authority.

13.12 :    Marking the Portable tanels.

13.12.1. Metal identification plate: There should be on every portable tank a rust proof metal plate permanently attached to the tank in a place rapidly accessible for inspection. Upon the plate should be marked by stamping, embossing or other means, at least the information indicated below. This plate should not be painted so as to obscure the marking thereon:

Manufacturers Name……………………………..
Date of Manufacture…………………………….
Tank serial No…………………………………….
Maximum allowable working pressure……kp/Cm2(psig)
Test Pressure…….kp/Cm2 (psig)
Total water capacity…………………litres(gallons)
Maximum Weight of liquids to be carried………..(Kilos Tons)
Maximum Gross weight………………………Kilo (Tons)
Control or permit identification of competent authority.
Hydraulic Test date……………………….
Authority who witnessed the Hydraulic Test……………………
Code, rules or regulations (by name or other identification) under which tank is designed……………..
13.12.2. Test date and markings: The date of the last hydraulic test and the witnessing authority mark should be clearly stamped on the metal identification plate specified above. The date of the last visual examination as prescribed by Section 13.11.4. should be visibly marked on the tank in a manner satisfactory to the competent authority.

13.12.3. Special purpose tanks should be marked to indicate the substance they are permitted to carry.

13.13.Certification of portable tanks.
