Question 491 Deck Safety

The correct answer is A) GMDSS (Global Maritime Distress and Safety System). GMDSS is a global communication service that provides distress alerting and a network for search and rescue (SAR) communications for mariners. It is a mandatory requirement for ships under the International Convention for the Safety of Life at Sea (SOLAS) and is designed to improve safety at sea by ensuring rapid alerting of shore-based rescue and coordination centers in the event of an emergency. The other options are incorrect because: B) INMARSAT is a satellite communication system, C) EPIRB (Emergency Position-Indicating Radio Beacon) is a device that transmits distress signals, and D) GPS (Global Positioning System) is a navigation system, not a communication service.
