Question 676 Deck Safety

The correct answer is D) operated continuously while vapors may be present. The reasoning is that when handling flammable liquids, it is essential to maintain continuous ventilation in the compartment to prevent the buildup of flammable vapors. This is a safety requirement outlined in various maritime regulations, as the presence of an explosive mixture of vapors and air can lead to a fire or explosion hazard. Shutting down the ventilation (option A) or operating it intermittently (option C) would allow the vapors to accumulate, creating a dangerous situation. Having the ventilation on standby (option B) is not sufficient, as the vapors need to be removed continuously while the flammable liquids are being handled.
