Question 780 Deck Safety

The correct answer is C) 130°F. The space containing carbon dioxide cylinders must be properly ventilated and designed to prevent an ambient temperature in excess of 130°F. This requirement is specified in the regulations governing the storage and handling of compressed gases, which apply to the Coast Guard Captain's License Examinations. The other options are incorrect because 75°F is too low for a temperature limit, 100°F may not provide adequate safety margin, and 165°F would likely be too high and could potentially compromise the integrity of the carbon dioxide cylinders.
