The International Group of P&I Clubs (IG Clubs) and the shipping line members of the Cargo Incident Notification System (CINS) have collaborated to produce a new set of guidelines for the carriage of Calcium Hypochlorite in containers. These new guidelines can essentially be considered "IMDG Code plus precautions" in that they include selected provisions from the IMDG Code plus additional precautions consistent with the science basis established in 1999 by consulting scientists advising the IG clubs. These new guidelines replace the Frequently Asked Questions (FAQs) produced by the IG clubs in 2010.
