DVB: CHANGES TO THE INDUSTRY CARRIAGE GUIDELINES
January 18, 2019
Joint industry guidelines for the carriage of divinylbenzene (DVB) in containers have been published by CINS (the Cargo Incident Notification System), the International Group of P&I Clubs and the TT Club. DVB is a chemical that is prone to polymerization (a form of self-reaction) and when shipped in bulk DVB polymerization can cause heat and flammable gas to be generated. If containers carrying DVB are not properly presented for carriage and properly stowed there is a risk of explosion and fire. In response to a recent series of polymerization incidents arising from the carriage of DVB the IMO approved amendments to the IMDG Code dealing with the way polymerizing substances are carried. These are contained in amendment 39-18 of the IMDG Code, which will be mandatory from 1 January 2020, but may be applied on a voluntary basis from 1 January 2019.
