Question 1326 Deck Safety

The correct answer is B) Only when there is a chance of their being seen by rescue vessels. This is the correct answer because distress flares and rockets should only be used when there is a reasonable chance that they will be seen by potential rescue vessels or aircraft. Setting them off at random intervals or immediately upon abandoning the vessel is not an efficient or effective use of these limited resources. Rescue crews need to be able to pinpoint the location of a distressed vessel, so flares and rockets should only be used when they can be seen. The other options are incorrect because setting them off at fixed intervals (A and C) may not coincide with the presence of rescue vessels, and immediately upon abandoning the vessel (D) may be too soon and waste the limited supply of flares and rockets.
