At the IMO OPRC-HNS TG8 meeting held in London over 29th September to 3rd October, 2008, ISCO joined with other delegations in agreeing to support the Secretariat in collating information on response to HNS incidents in order to address data gaps that exist and to submit information to the future meetings of the Technical Group.

At TG9 in July 2009, ISCO was asked to continue this work as an ongoing project.


Information collected so far includes case histories of responses to incidents involving toxic sludge, MTBE, Naphtha, Sulphuric Acid and Freon (a CFC compound).


It is the international spill response community that has hands-on experience in dealing with HNS incidents – solving the problems and developing techniques that work – experience that will eventually be used in developing response guidance manuals.


ISCO wants to hear from its members and others that can make a contribution to our collective effort. We want to hear not only from contractors but also from manufacturers and researchers who are developing new equipment and technology for HNS incident response.
