CHAPTER 7.1 Seperate they’re dangerous, Together they’re deadly Segregation MSC BASIC IMO training(Amdt. 35-10)
CHAPTER 7.2 7.2.1 General The following segregation terms are used throughout this Code: “Away from” (3 metres) “Separated from” (6 metres) “Separated by a complete compartment or hold from” (12 metres) “Separated longitudinally by an intervening complete compartment or hold from” (24 metres) MSC BASIC IMO training(Amdt. 35-10)
CHAPTER 7.2 7.2.1 General In addition to the general provisions, there may be a need to segregate a particular substance, material or article from other goods which could contribute to its hazard. Particular provisions for segregation are indicated in the DGL and, in the case of conflicting provisions, always take precedence over the general provisions. UN1001 UN1017 UN1597 UN2048 MSC BASIC IMO training(Amdt. 35-10)
CHAPTER 7.2 7.2.1 General Except for class 1, the segregation provisions for substances, materials or articles having more than two hazards (2 or more subsidiary risk labels) are given in the DGL. UN1045 UN1036 UN1295 UN 1308 MSC BASIC IMO training(Amdt. 35-10)
CHAPTER 7.2 7.2.2 Segregation groups Similar technical properties UN1935 UN1939 UN2785 UN3253 UN3367 UN2024 MSC BASIC IMO training(Amdt. 35-10)
CHAPTER 7.2 7.2.1.7 N.O.S entries ( not otherwise specified) It is recognized that not all substances falling within a segregation group are listed in the Code by name. These substances are shipped under N.O.S entries. Although these entries are not listed themselves in the above groups, the shipper shall decide whether allocation under the segregation group is appropriate. UN 1760 CORROSIVE LIQUID, N.O.S. UN 2924 FLAMMABLE LIQUID, CORROSIVE, N.O.S. UN 3098 OXIDIZING LIQUID, CORROSIVE, N.O.S. MSC BASIC IMO training(Amdt. 35-10)
NO SEGREGATION REQUIRED CHAPTER 7.2 7.2.1.11 Substances of the same class • Substances of the same class may be stowed together without regards to segregation required by secondary hazards (subsidary risk labels), provided the substances do not react dangerously with each other and cause: • Combustion and/or evolution of considerable heat • Evolution of flammable, toxic gases • The formation of corrosive substances • The formation of unstable substances EXPLANATION PRODUCER (MSDS) MSC BASIC IMO training(Amdt. 35-10)
NO SEGREGATION REQUIRED CHAPTER 7.2 7.2.1.11 Special provisions No segregation needs to be applied between dangerous goods of different classes which comprise the same substance but vary only in their water content.
