Question 1153 Deck Safety

The correct answer is A) switching the light on only when necessary. The SOLAS (Safety of Life at Sea) regulations require that inflatable liferafts have interior lighting powered by batteries to provide illumination at night or in low visibility conditions. To conserve battery power and ensure the lights last for the required duration, SOLAS specifies that the interior lights should only be used when necessary, rather than being left on continuously. This is the most efficient way to maximize the battery life and provide the necessary lighting when needed during an emergency. The other options are incorrect because B) and D) suggest there is no way to save power, which goes against the SOLAS requirement to conserve battery life, and C) of unscrewing the bulb would disable the lighting entirely, which is not permitted under the regulations.
