Question 570 Deck General

The correct answer is B) The requirement for through-ventilation. Through-ventilation is not a problem when carrying coal. Coal cargoes require proper ventilation to prevent issues like spontaneous heating (A), corrosion (C), and methane gas generation (D). Proper through-ventilation is a safety requirement to mitigate these hazards when transporting coal. The other options (A, C, and D) are all potential problems that need to be addressed when carrying coal, but the requirement for through-ventilation is not considered a problem in itself.
