ventilation)

The possible need to apply water and the consequent

risk to the stability of the ship

CHAPTER 7.1


7.1.12 Stowage of goods of class 5.2 (organic peroxides)

Organic peroxides: stowage category D

Organic peroxides shall be stowed away from living quarters or acces

to them

Organic peroxides shall be stowed away from sources of heat

Protected from direct sunshine and stowed in a cool, well-ventilated

place

It may become necessary to take the appropriate emergency action,

such as jettisoning

CHAPTER 7.1


7.1.13 Stowage of goods of class 6.1 ( toxic substances)

Toxic substances which are also flammable liquids

• Stowed in a mechanically ventilated space

• Kept as cool as reasonably practicable

• Should be stowed “away from” all sources of heat

CHAPTER 7.1


7.1.15 Stowage of goods of class 8 ( corrosive substances)

All substances for which unprotected plastics packagings are

permitted shall be kept as cool as reasonably practicable as the

resistance of most plastics decreases at high temperatures

Corrosive substances which are also flammable liquids

• Kept as cool as reasonably practicable

• Should be stowed “away from” all sources of heat

CHAPTER 7.1


7.1.16 Stowage of goods of class 9

AMMONIUM NITRATE BASED FERTILIZER UN2071

• In case of fertilizer in containers it is sufficiënt if, in case of an

emergency, the cargo is accessible trough free approaches

(hatch entries), and mechanical ventilation enables the master to

exhaust any gases or fumes resulting from decomposition

To be considered before loading:

• The possible need to open hatches in case of fire (max.

ventilation)

• The possible need to apply water and the consequent risk to the

stability of the ship

CHAPTER 7.1

Segregation

CHAPTER 7.2


7.2.1 General

The following segregation terms are used throughout this Code:

1. “Away from” (3 metres)

2. “Separated from” (6 metres)

3. “Separated by a complete compartment or hold from” (12 metres)

4. “Separated longitudinally by an intervening complete compartment

or hold from” (24 metres)

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 UN1017UN1597 UN2048

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.

CHAPTER 7.27.2.1.7 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.

CHAPTER 7.27.2.1.11 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:

1. Combustion and/or evolution of considerable heat2. Evolution of flammable, toxic gases3. The formation of corrosive substances4. The formation of unstable substances

EXPLANATION PRODUCER (MSDS)

NO SEGREGATION REQUIRED


CHAPTER 7.27.2.1.11 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.
