The transport of goods requiring specialised treatments have changed over the years, from bulk shipments to containerised cargo either by sea or air freight.
Quarantine fumigation have numerous forms of treatments available to accommodate the requirements for agencies involved in this highly specialised field.
Pest infestation is not uncommon on-board vessels and ships, it is essential to take charge of the situation to eliminate pests especially rats, as part of legal requirements. Prior conducting vessel fumigation, it is necessary to vacate risk areas and ensure that effort has been made to seal all openings to prevent the fumigant (Methyl Bromide) used from escaping.
Re-entry into the fumigation area is only allowed when it has been declared safe and free of gas by the fumigators-in-charge. This is after tests are carried out to confirm the gas concentration level is below OES (Occupational Exposure Standard).
Container fumigation is the treatment of a commodity or the container itself to eliminate the risk of pests or disease from entering or leaving the country or state.
Containers can be fumigated at different times in the transport chain. If done offshore before shipment, the container will usually be aerated or ventilated before loading on a ship. Under international maritime rules containers under fumigation are only permitted on a ship at the discretion of the master, who will usually require them to be aerated or ventilated. Even if these containers are aerated before shipping, some residue of fumigant is likely to remain because of the slow release of gas absorbed into the cargo. Documentation about fumigation of a container such as treatment certificates, customs declaration or warning labels may not be a reliable indication that fumigation has been carried out. Therefore anybody required to open a container must do so with great care and take appropriate precautions to prevent exposure to possible toxic gases.
