You must be able to put the PFD on in a reasonable amount of time in an emergency.
Readily accessable
Ideally, they should be worn at all times. If you fall overboard, you won't be able to retrieve a PFD (Personal Floatation Device) from a locker on the boat.
PFDs being worn by passengers
any that are sealed in their oringinal plastic bags
Readily means immediately. It also means agreeably.
The tires on most automobiles are readily accessible if the tires need repair.
i really dont know
Serviceability means that fastening hardware is not broken and operates correctly, the webbing or straps are not ripped torn or missing. Fabric tears have not resulted in loss of buoyant material and that the buoyant material has not hardened or been contaminated by oil or other liquids. The flotation device must be structurally sound and free of rotted or corroded components. I would also personally take it as far as saying the PFD must fit properly and be appropriate for the intended use. It is also important to keep them readily accessible -I know some one that received a ticket for having the PFD's stored under the bow and not in a place where they could be quickly grabbed in an accident. I think most if not all states also require children under the age of 12 to wear a PFD at all times when the boat is in motion (for powerboats at least).
A Personal Flotation Device (PFD) must meet specific legal requirements that vary by jurisdiction, but generally, it must be Coast Guard-approved and appropriate for the type of boating activity. PFDs must be in good condition, readily accessible, and the correct size for the user. Additionally, certain regulations may require a specific number of PFDs on board based on the vessel's capacity. Always check local laws for specific requirements.
Children under the age of 13 are required to wear a U.S. Coast Guard-approved personal flotation device (PFD) while underway in an open vessel on federally controlled waters. This regulation is in place to enhance safety and reduce the risk of drowning in the event of an accident or capsize. The PFD must be properly fitted and readily accessible for the child during the entire voyage.
Fire extinguishers should be stored and mounted where they are readily accessible on a boat, where they will not be damaged and where they can be inspected regularly.
