governments, usually without reference to practices in other countries. As a result standards and procedures varied widely, even though shipping is the most international of all industries.

The Convention prescribes minimum standards relating to training, certification and watch-keeping for seafarers which countries are obliged to meet or exceed.

The Convention did not deal with manning levels: IMO provisions in this area are covered by regulation 13 of Chapter V of the International Convention for the Safety of Life at Sea (SOLAS), 1974, whose requirements are backed up by resolution A.890(21) Principles of safe manning, adopted by the IMO Assembly in 1999, which replaced an earlier resolution A.481(XII) adopted in 1981.

The Articles of the Convention include requirements relating to issues surrounding certification and Port State Control.

One especially important feature of the Convention is that it applies to ships of non-party States when visiting ports of States which are Parties to the Convention. Article X requires

Parties to apply the control measures to ships of all flags to the extent necessary to ensure that no more favorable treatment is given to ships entitled to fly the flag of a State which is not a Party than is given to ships entitled to fly the flag of a State that is a Party.

The difficulties which could arise for ships of States which are not Parties to the Convention is one reason why the Convention has received such wide acceptance. By December 2000, the STCW Convention had 135 Parties, representing 97.53 percent of world shipping tonnage..

While carbon dioxide is used in some extinguishers as an inert propellant the gas is also used

extensively as a blanketing agent. In a carbon dioxide portable extinguisher, the carbon dioxide is in liquid form and is at a pressure of 6 bar at 20℃ , necessitating a far stronger container. This type of extinguisher can only be recharged ashore. To check for leakage a record should be kept of the weight of the extinguisher. Alternatively the liquid level can be determined by using a

special instrument which uses a radioactive source and a Geiger-Muller counter to detect the gas/liquid interface although this method is usually only used on large fixed CO 2 installation.

This could be lethal if discharged accidentally in a confined space and for this reason this type of extinguisher in not allowed in the accommodation.

73. Which of the following statements is not true ?

A. Carbon dioxide is usually used as a propellant.

B. Carbon dioxide is usually used as an extinguishing gas.

C. If the carbon dioxide is used as a blanketing agent, it should be pressurized. D. The carbon dioxide extinguisher can only be used ashore. 74. In what state is the carbon dioxide in the portable extinguishers?

A. powder B. dry ice C. liquid D. gas

75. How do you detect the leakage of a carbon dioxide portable extinguisher?

A. to record gas pressure. B. to measure its weight.

C. to measure its liquid level. D. to monitor the radioactive source.

76. The reason that the carbon dioxide extinguisher can t be used in the accommodation is that_____.

A. carbon dioxide is a toxic gas B. carbon dioxide is an inertial gas
