What must each life jacket have attached to it?

Each life jacket must have Type I retro reflective tape attached to it to enhance visibility in emergency situations. This type of tape reflects light, making it easier to see life jackets in low-light conditions, particularly during nighttime rescues or in poor weather. The reflective properties are crucial for improving the chances of being spotted by rescuers or other vessels, which can significantly increase survival rates in emergencies on the water.

Other options, while they may relate to safety equipment, do not distinguish themselves as mandatory attachments for each individual life jacket. For example, the vessel's name might be required on certain safety equipment, but it's not a requirement for every life jacket. A hydrostatic release is typically associated with life rafts or other inflatable devices, not life jackets. Similarly, an operating cord pertains to certain gear but is not a standard requirement for life jackets themselves. Therefore, Type I retro reflective tape is the correct and essential requirement for each life jacket, ensuring that they remain visible and effective during critical situations.
