Question 1198 Deck Safety

The correct answer is D) Make sure the operating cord is secured to the vessel before throwing it over the side. This is the correct answer because when launching an inflatable liferaft by hand, it is crucial to ensure the operating cord is secured to the vessel before deploying the raft. This prevents the raft from drifting away from the vessel after inflation, allowing the crew to safely board the raft. The other options are incorrect because: A) Detaching the operating cord should be done after the raft is fully inflated, not during the launch process. B) Turning the CO2 valve is not a manual operation, as the raft should automatically inflate when the operating cord is pulled. C) Opening the liferaft casing is a necessary step, but not the key operation when actually launching the raft.
