A good training officially provided by SIGTTO for those involved in maritime transportation of liquid gases. The students, who have successfully completed the lesson, should be considered as having enough knowledge of the common types of hazards associated with such activity, including flammability, toxicity, low pressure and temperatures, chemical burns and others. The first in the list, flammability, is treated as the most dangerous one.
That is the reason why the ship designers pay so much of their attention to arrange for the most effective containment of the transported cargoes in order to limit the amount of gases that escape to the atmosphere. In addition to that, the vessels and ports are in possession of the relevant design specifications for the electrical arrangements ensuring elimination of any ignition sources in the hazardous areas.
All gases that are carried in bulk on board gas carriers, except for the chlorine, are of flammable nature, and the vapors are easily ignited. This does not relate to the ammonia requiring higher energy of ignition. The fires that normally follow the leakage of ammonia are less likely… The lesson will provide all essential information that shall be possessed by everyone dealing with marine gas transportation in a safe manner.
