What type of distress signals must be carried if having life rafts on board?

When carrying life rafts on board, it is required to have a supply of pyrotechnic distress signals. These signals play a crucial role in emergency situations because they are highly visible and can be seen from a distance, greatly enhancing rescue operations' chances. Pyrotechnic signals, including flares and other devices that produce a bright light or loud noise, help to alert nearby vessels or aircraft to your situation, making them essential in a survival scenario.

Visual flares, while useful, fall under the broader category of pyrotechnic distress signals, which include additional types of signals that might not be strictly visual. A radio distress signal, although important for communication, is not sufficient on its own when considering the requirements for distress signaling, especially in the absence of any other communication means. Moreover, stating that no distress signals are required is incorrect, as safety regulations mandate appropriate distress signaling equipment to be carried when lifeboats or rafts are onboard for effectively managing emergencies.
