Cargo IMDG Flashcards
The International Maritime Dangerous Goods (IMDG) Code
IMO Dangerous Goods Conventions
There are two international conventions produced by IMO which govern the transport of dangerous goods:
SOLAS
The International Convention for the Safety of Life at Sea, 1974 (1974 SOLAS Convention), as amended, Chapter VII of which deals with the safety aspects of the transport of dangerous goods by sea.
MARPOL
The International Convention for the Prevention of Pollution from Ships as modified by the Protocol of 1978 (MARPOL 73/78), Chapter III of which deals with prevention of pollution arising from the transport of dangerous goods by sea.
All IMO Member States are required to implement national legislation to address the transport of dangerous goods, through their legal obligations under the SOLAS and MARPOL Conventions. However, to assist them, the IMO has produced a detailed set of requirements covering the transport of packaged dangerous goods by sea in a separate Code; the International Maritime Dangerous Goods (IMDG) Code.
The IMDG Code is based on an internationally agreed system which:
1 Groups dangerous goods together based on the hazards they present in transport (classification).
2 Contains the dangerous goods in packagings/tanks which are of appropriate strength and which will prevent the goods escaping.
3 Uses hazard warning labels and other identifying marks to identify dangerous goods in transport.
4 Requires standard documentation to be provided when dangerous goods are being transported.
5 Lays down principles for ensuring that incompatible dangerous goods are kept apart.
6 Lays down principles for where to place dangerous goods on board ship to ensure safe transport.
7 Provides emergency response advice for dangerous goods involved in a fire or spillage on board ship.
International Maritime Dangerous Goods (IMDG) Classes
Class 1 - Explosives.
Class 2 - Gases: Compressed, Liquefied or Dissolved under Pressure.
Class 3 - Flammable Liquids.
Class 4 - Flammable Solids or Substances.
Class 5 - Oxidizing Substances (agents) and Organic Peroxides.
Class 6 - Toxic and infectious Substances.
• What is the “Puwer” regulations
PUWER” Regulations
MGN 331 (Provision and Use of Work Equipment) Regulations 2006
The majority of injuries to crew involving work equipment occur as a result of persons being struck by or caught in moving parts of such equipment. The cause is often attributed to incorrect practices, inadequate training or to errors of judgement. Other types of serious accident are caused by the failure of work equipment, or missing safety guards. Accidents can be avoided through careful design and selection of work equipment.
• What is the “Loler” regulations
Merchant Shipping and Fishing Vessels (Lifting Operations and Lifting Equipment) Regulations 2006
MGN 332
The majority of injuries to crew involving lifting equipment occur as a result of persons being struck, crushed or caught in moving parts and equipment. The cause is often attributed to incorrect practices or to errors of judgement. Other types of serious accident are caused by the failure of lifting equipment or single point failures of equipment. Inappropriate use of lifting equipment and failure of lifting equipment can also have an adverse effect on a vessel’s stability, and on smaller vessels this could possibly lead to capsize.
• Explain regular maintenance as per the LOLER regs
Regular Maintenance
In order to ensure all parts of work equipment are kept in good repair and working order, regular preventative maintenance should be carried out.
Maintenance should include regular examinations by a competent person. It is recommended that these be carried out as necessary but at least once annually and include checks for general material defects such as cracks, distortion and corrosion that will affect safety or ability to perform required function.
An appliance or item of equipment should be taken out of service until it can be subjected to examination when there is suspicion that it may not be performing correctly or has been subjected to treatment likely to cause damage.
Greasing should be thorough and frequent as dry bearings impose additional loads that can lead to failure.
The condition of all ropes and chains should be checked regularly for wear, damage and corrosion and replaced as necessary.
Shackles, links and rings should be renewed when wear or damage is evident.
Structures should be examined frequently for corrosion, cracks, distortion and wear of bearings, securing points etc.
Hollow structures such as gantries or masts should be checked for trapped water inside. If found the structure should be drained and then sealed.
There should be regular function tests of controls, stops, brakes, safety devices etc for work equipment, preferably before the start of operations.
• Lifting equipment
Lifting equipment
A valid certificate of testing and thorough examination by a competent person should be in force for every item of lifting equipment, accessory for lifting and loose gear. All items should be tested, and then thoroughly examined and certificated for use.
S.I. 2006/2184 AND MGN 332 (M+F)
• After manufacture or installation; or
• After any repair or modification that is likely to alter the safe working load
(SWL) or affect the strength or stability of the equipment.
A certificate for a ship’s lifting equipment is valid for no more than five years.
In addition to the strength and stability of the lifting equipment, consideration should also be given to the stability, angle of heel and potential down-flooding of any vessel as a result of the use of a crane, davit, derrick or other lifting device fitted on it. This is especially important where a crane is to be fitted on a work boat or other small vessel, and it is recommended that advice should be sought from the crane manufacturer in such cases prior to the crane being fitted. Similarly, it is recommended that a check of the vessel’s stability should be carried out by a suitably qualified person prior to installation of a crane, and following any modification to it, to ensure that the vessel is capable of operating safely with the crane fitted and in use. Failure to do this could have serious consequences for the safety of the vessel and the workers on it.
