Question 791 Deck General

The correct answer is A) -18°C to 46°C. The expansion allowance for hazardous cargoes is based on an ambient temperature range of -18°C to 46°C, as per the regulations outlined in 46 CFR 39.2101. This temperature range accounts for the typical environmental conditions that a tank vessel may encounter during loading and transport operations. The other options are incorrect because they do not align with the regulatory requirements. Option B) 0°C to 100°C is too broad, Option C) -10°C to 90°C is slightly outside the specified range, and Option D) -40°C to 50°C does not match the regulatory requirements.
