IG, TT Club, CINS, publish DVB carriage guidelines

The Cargo Incident Notification System (CINS), the International Group of P&I Clubs and TT Club have produced joint industry guidelines on the carriage of divinylbenzene (DVB) in containers.

DVB is a chemical that is prone to polymerization (a form of self-reaction) which, when shipped in bulk, could cause heat and flammable gas to be generated.

The stowage of containers carrying DVB aboard vessels therefore could present a risk of explosion and fire if the containers were not presented properly for carriage.

After a series of polymerization incidents arising from the carriage of DVB by sea, the International Maritime Organization amended the IMDG Code in 2018, approving changes to the way polymerizing substances such as DVB were carried, by means of amendments to the IMDG Code. Amendment 39-18 to the IMDG Code will be mandatory from January 1st 2020 but might be applied on a voluntary basis from January 1st 2019.

To ensure the safe carriage of DVB in containers before 1 January 2020 when the amended IMDG Code requirements come into force mandatorily, the joint industry guidelines have highlighted the practices set out in the IMDG Code amendments and recommended that these be followed now on a voluntary basis
