Question 1472 Deck Safety

The correct answer is D) 42 months. According to the regulations, each distress signal and self-activated smoke signal must be replaced no later than 42 months from the date of manufacture, or by the marked date of expiration, whichever comes first. This is the requirement set forth by the U.S. Coast Guard for the lifespan of these important safety devices. The other options are incorrect because 6 months (A) and 12 months (B) are too short, while 24 months (C) is longer than the 42-month requirement.
