When must a PDF or lifejacket be replaced?

A personal flotation device (PFD) or lifejacket must be replaced if it is damaged, shows signs of wear and tear, or fails to meet safety standards. Additionally, if a PFD has reached its expiration date or if its buoyancy has diminished due to waterlogging or other factors, it should be replaced. Regular inspections and adherence to manufacturer guidelines are essential for ensuring safety.
