3.4.3. Fumigation in transit Fumigation in transit should be carried out only at the discretion of the ship's captain. This is a clear need to understand the shipowners, charterers and all other interested parties when considering the transport of cargo which may be infected. Many factors must be considered when selecting methods of fumigation. The master should know the requirements of the rules of the state of the shipowner on transit fumigation. This process should be consistent with the administration of the port of embarkation. The process is carried out in two ways:

  1. fumigation, in which the processing load occurs in a sealed room during the voyage and which was not made before sailing degassing;
  2. fumigation of cargo at the port of loading, when the degassing was carried out before the ship, but the certificate of purity for commercial premises can not be issued due to the residual gas and the fact that the cargo spaces were closed again before sailing. Before you decide to set sail with fumigated cargo, should take into account the fact that, because of working conditions, the circumstances listed in may arise unintentionally, ie ship can sail on demand before the start of fumigation chemical process. In such circumstances the potential hazards can be as large as in the case of planned fumigation in transit, and therefore must comply with all the measures presented in the following paragraphs. Before you decide to carry out the planned fumigation in the port and its extension into the sea, the necessary precautions must be taken. These include:

  1. at least two members of the crew (including one officer) who have received training (see., shall be appointed by the captain responsible for maintaining a safe environment, engine rooms and other work areas, after the captain of the vessel took responsibility for fumigation in transit from the representative of the fumigation company (see.;
  2. trained representatives captain should instruct the crew before the fumigation, fumigation and inform the representative of the company on the results of instruction. Empty cargo spaces should be inspected and / or tested for possible gas leakage with instruments so that appropriate measures to seal could be carried out before or after loading. The representative of the fumigation company together with trained representatives of the master should determine whether the cargo spaces to be fumigated, are or may be sufficiently tight to prevent leakage of the fumigant in the living quarters, engine room and other working areas of the vessel. Particular attention should be paid to potential problem areas such as bilge and cargo system. Upon completion of such inspection and / or testing of a representative of a fumigation company must issue a certificate to the captain that such inspection and / or testing have been carried out, what measures have been taken and that the cargo spaces are or may be satisfactory for fumigation. If the cargo space is not enough tight, the representative of the fumigation company must give the captain and other interested parties to the act. Living quarters, engine room, the room used to control the ship, frequently visited working areas and storage areas, such as areas under the tank directly adjacent to the cargo spaces which have undergone fumigation in transit shall be controlled in accordance with the requirements of paragraph Particular attention should be paid to monitoring the concentration of gas in the problem areas, which were discussed in Trained representatives captain appointed in accordance with paragraph. should be provided and be familiar with:

  1. Information sheets on the safe use of the drug; and
  2. instructions on the label of the fumigant or packaging, such as a fumigant manufacturer's recommendations regarding the methods for determining the fumigant in air, its behavior and hazardous properties, symptoms of poisoning, first aid and appropriate special medical treatment, as well as procedures for emergencies. The vessel shall have:

  1. gas analyzers and associated tubing for determining the concentration of gas in accordance with paragraph, together with instructions for use and standards PDK;
  2. instructions for the destruction of residual fumigant;
  3. at least four sets of personal protective equipment, as appropriate for the fumigant;
  4. necessary medicines and medical equipment;
  5. a copy of the latest version of the Medical first aid guide for accidents involving dangerous drugs (MFAG). Particular attention is given to the table 550. The representative of the fumigation company must notify the captain of the cargo spaces to be fumigated, as well as any other room in which dangerous to enter during the fumigation. Share fumigant during fumigation company representative must ensure security controls surrounding areas. If the cargo spaces have cargo to be fumigated in transit, then:

  1. after laying a fumigant, a fumigation company representative together with trained representatives captain primaries check for gas leaks in the event of leakage shall be additional sealing. If the captain is satisfied with the implementation of all the measures listed in paragraph. ..., the vessel can leave port. Otherwise, you must meet the requirements listed in section. or If the conditions are not met,


  1. After fumigation vessel shall be detained in port or at a relevant berth or at anchor as long as is necessary to ensure that the gas in the fumigated cargo spaces could reach sufficiently high concentrations to detect possible leaks.Particular attention should be given to those cases in which were used solid or liquid fumigants and requires a long period of time (usually from 4 to 7 days if not used recirculation system) to achieve a high concentration, allowing to determine the leak. If leaks are defined, the vessel must not leave the port until the detection of sources of these leaks and neutralize them. After removing all the errors and the readiness of the vessel to sail, ie lack of a gas leak, a spokesman for the fumigation company must issue a written report to the captain that:
    1. gas in the cargo spaces reached a high enough concentration to detect any possible leaks;
    2. premises adjacent to fumigated cargo spaces have been tested and are free from gas;
    3. representative of the vessel is able to deal with the provision of equipment, designed to determine the concentration of gas.


  1. After the fumigant tab and immediately after leaving the vessel should be representative of the fumigation board to remain on until the gas in the fumigated cargo spaces reaches a high enough concentration to detect any possible leaks or up until fumigated cargo is unloaded (see ., and in any case ensure safety of the crew. Before leaving the ship, he must ensure that the ship is in a safe condition, ie, there are no gas leaks. He shall issue a written report to the captain that the condition n., and have been met. After bookmark fumigant representative fumigation company should hang warning signs at all entrances to the premises, which informed the captain in accordance with These warning signs should indicate the name of the fumigant and the date and time of the start of fumigation * . At the appropriate time after the laying of the fumigant representative fumigation company together with a representative of the captain should check the accommodation, engine rooms and other working areas for the absence of dangerous gas concentration. After completing all the requirements for safety representative fumigation company must formally in writing to transfer the responsibility of the captain to ensure a safe environment for all living and working spaces. The representative of the fumigation company must ensure that the ship gas analysis and reliable means of personal protection and to ensure supply of detector tubes for gas sampling in accordance with paragraph. Check the gas concentration in certain places, including at least, the premises referred to in paragraph., shall be carried out during the voyage, at least every eight hours or more frequently if recommended by the representative of the fumigation company. The reading should be recorded in the logbook. Except in cases of emergency, cargo spaces sealed for fumigation in transit should never be opened to the sea and they have no one should enter. If necessary, the inputs must be at least two people in the appropriate personal protective equipment, all wearing seat belts attached to the cable that controls the people outside this room, also equipped with a compressed air machine. If you want to ventilate a cargo space or room must be taken all the necessary measures to prevent the accumulation of gas in residential or office space. For this purpose it is necessary to carefully monitor the premises. If at some point the concentration of the gas in these areas exceeds the threshold value (TLV), then there should evacuate and seal the additional cargo spaces. If the cargo space is further sealed after ventilation it should not be assumed that it is absolutely free of gas before entering into it, should be carried out the necessary measurements of gas and appropriate precautions. Before the arrival of the vessel, usually not less than 24 hours, the master shall inform the relevant authorities of the country of destination and ports of call that fumigation is carried out in transit. This information should include the type of fumigant used, the date of fumigation, the cargo spaces where fumigation, information on whether the ventilation is started. On arrival at the port of landing, the master should also provide information in accordance with paragraph. and On arrival at the port of discharge, the requirements of host countries concerning fumigated cargo unloading.Before entering the fumigated cargo space, trained personnel fumigation company or other authorized persons using personal protective equipment should conduct a thorough inspection of premises, to ensure the safety of personnel.Measurements of gas concentrations should be recorded in the logbook. If necessary, or in an emergency, the captain may start ventilation fumigated cargo spaces under the terms of, to ensure the safety of the crew on board. If this work is to be performed in the open sea before its implementation captain must take into account the state of the sea and the weather. During unloading, use only mechanical means to staff not to enter the cargo spaces where the fumigated goods. However, when the presence of personnel in cargo spaces is necessary for processing and control handling equipment should be continuous monitoring of gas concentration in order to ensure the safety of operating personnel.If necessary, these personnel should be equipped with appropriate personal protective equipment. At the last stage of discharge when there is a need to staff entered the cargo spaces, this input should be allowed only after when such cargo spaces will be free of gas. Upon completion of the discharge, when the ship is free from fumigant and certified this should remove all the warning signs. In this context, any action must be recorded in the logbook.

* example of such a warning sign is given in Annex 3
