Shipping accidents and disasters occur time and again. Some of this is due to incorrect information about the load, weight or incorrect or missing classification of dangerous goods.
Inadequate load securing leads to transport damage. It is not uncommon for ships to be completely lost.
All incidents are being thoroughly investigated by various authorities until a final verdict is reached. Afterwards, considerations are made as to how such incidents can be prevented in the future.
We as shippers/container packers experience these results in the form of changes, additions or special comments to or in regulations and laws.
This is, for example, the biennial update of the IMDG Code, the regulations for the transportation of dangerous goods by/on ships. The details can be found in columns 15, 16a and 16b of Table 3.2.
Column 15 of the IMDG Code refers to the EMS Code.
It is divided into two parts:
- Recommendations for fighting fires with the abbreviations F-A to F-J
- Recommendations for combating leaks with the abbreviations S-A to S-Z
The shipper of dangerous goods must state the abbreviation of the EMS code in relation to the UN number in the transport document.
Example: UN-1950 pressurized gas packagings (aerosols)
- EMS code: F-D
- EMS code: S-U
If the transport unit, e.g. the container, contains pressurized gas packages, the following rules (excerpts) apply to the ship’s crew in the event of an accident or leakage.
Column 16a of the IMDG Code refers to the stowage and handling of dangerous goods on ships. The example refers in part to hazardous goods of classes 2-9, which are packed in limited quantities. They can be stowed on deck or below deck.
In detail, the instructions given specifically for the UN number apply.
Congestion category A
Cargo ships or passenger ships whose number of passengers is limited to a maximum of 25 or 1 passenger per 3 m of the total length of the ship, whichever is greater.
-> On deck or below deck
Column 16b of the IMDG Code refers to the segregation of transport units on the ship, depending on the dangerous goods they contain.
The instructions refer to the UN number 1950 pressurized gas packs.
SW1: protected from heat sources
SW22: For PRESSURE GAS PACKAGES with a maximum capacity of 1 liter: Stowage category A.
For PRESSURE GAS PACKAGES with a capacity of more than 1 liter: Stowage category B.
For WASTE PRESSURE GAS PACKAGING: Stowage category C, free of living and recreation rooms.
The basis for such regulations is the International Convention for the Safety of Life at Sea(SOLAS), which was adopted in 1914 after the sinking of the Titanic.
It is updated at regular intervals as required/on special occasions. Principles are agreed here, which are then implemented in detailed measures by the International Maritime Organization(IMO).
One of these is the “verified gross weight” that was introduced in 2014 with the MSC.1/Circ. 1475 9 June 2014 was put into force.
This topic will be dealt with in one of the next LaSi blog episodes.
