Aviation Standard Test Battery-E (ASTB E) Practice Test

What is the purpose of lifelines erected around the weatherdecks of a ship?

1. To provide support for cargo

2. To prevent personnel from falling overboard

3. To mark hazardous areas

4. To assist with navigation

The correct answer is: To prevent personnel from falling overboard

The purpose of lifelines erected around the weatherdecks of a ship is to prevent personnel from falling overboard. Lifelines are typically made from strong materials and are securely fastened to the ship, creating a barrier that enhances safety for crew members and passengers working or moving around on deck. This is particularly important in rough weather or during maneuvers when the ship might roll or pitch, increasing the risk of individuals losing their balance and falling into the water. While the other choices describe various functions or features that could exist on a ship, they do not specifically address the unique safety role that lifelines serve in protecting personnel. For instance, while cargo support is essential, lifelines do not serve this function. Marking hazardous areas and assisting with navigation are also important aspects of maritime operations, but these functions are fulfilled by different equipment and protocols, not lifelines. Thus, the fundamental safety role of lifelines is to act as a physical barrier against falls, underscoring their critical importance in maritime safety practices.
