North P&I Club has published a new free-to-download loss prevention briefing warning its members of the hazards associated with routine fumigation of agricultural products on ships.
The warning follows an explosion of pesticide gases on a panamax vessel, loading corn at Paranagua, Brazil, at the end of December 2015. This resulted in significant structural damage and was one of number of similar incidents reported during the last five years in Brazil and the USA. According to North’s loss prevention director Tony Baker, ‘The application of fumigant on vessels carrying cargoes such as grains, seed cakes and logs is common practice. However, failure to disperse the fumigant pellets properly has led to self-heating problems.
‘This can cause heat damage to the cargo or ignition and subsequent explosion of high concentrations of fumigant gases. Some of these incidents have been significant enough to lift the vessel’s secured hatch covers, resulting in major structural damage.’
Loss prevention deputy director Collin Gillespie says, ‘Fumigation should never be conducted by a ship’s crew. However, crew members must be made aware of the hazards of fumigation and the risks it poses to human health. They should fully understand the duties of the fumigation company and the responsibilities of the fumigator in charge.’
The new loss prevention briefing, which supplements the International Maritime Organization (IMO) recommendations for safe fumigation of cargo holds (MSC.1/Circ.1264), aims to provide crew members with a practical understanding of the process, its risks and how these can be minimised.
In addition to describing the hazards of pesticide gases, the briefing sets out the responsibilities of the fumigator in charge; procedures for fumigating in port and in transit; and safety measures which should be taken before, during and after fumigation. It also advises shipowners and operators to incorporate a suitable fumigation clause in their charterparties.
‘While the incorporation of a fumigation clause will not prevent incidents from occurring, it will help ensure that all fumigation operations are conducted in accordance with IMO recommendations,’ says Gillespie. ‘The clause also sets out the division of responsibilities regarding fumigation.’
