Have look through the website as you have suggested. The website did
stated the type but does not have the required floatation hours for each type. cheers "LD2" wrote: go to this site http://www.uscgboating.org/ LD "seanny_boy" wrote in message ...

Exactly what do you mean with "required floatation hours"? First, in the more than 20 years I've been working with different kind of rescue equipment, I have never seen any PFD or similar equipment with specified flotation hours. Basically, there are two main types of PFD's: a) Rigid (non-inflatable) PFD's using some kind of flotation foam, e.g. Airex(R) or similar. b) Inflatable PFD's using CO2 cartridges. Rigid PFD's may keep a person afloat for virtually unlimited time as long as the PFD itself is not damaged in any way, while inflatable PFD's may keep a person afloat as long as the PFD is inflated, i.e. not leaking, not punctured etc. Second, no PFD will guarantee survival even if "flotation hours" were specified. Basically, the two most common reasons for not surviving a boating accident is drowning and hypothermia. A PFD is designed to keep a person afloat to prevent drowning, but is generally NOT designed to prevent hypothermia (which require survival suits or similar equipment). Dependent on water temperature and other factors, hypothermia may in worst case occure after only a few minutes, and it's therefore almost impossible to specify a "survival time" when using a PFD.

The Code of Federal Regulations (160.052-7) specifies a test in which the inserts of any foam cored PFD must be submerged for a minimum of 24 hours in which they must maintain buoyancy. So, in a sense, they are guaranteed for 24 hours. Later, Tom |

I have visions of someone bobbing around the Atantic, frantically typing a msg to find how how long he can float... I'd probably use my time/communications a bit differently, but you never know...

The new PFDs with the dense cell foam will probably float forever. I have found
old type 4s stuck in the mangroves that may have been there for years and they still float fine, the cover and straps will fail long before the foam waterlogs. I think the whole idea of "floatation hours" dates from the days when these things were stuffed with Kapok. |

I've never heard of any "flotation hours" rating. If they're in good proper
condition a person will die of other causes before the PFD sinks. LD "seanny_boy" wrote in message ... Have look through the website as you have suggested.

Report abuse: http://www.BoatForumz.com/eform.php?p=60527 thank you for all that reply. I know this might sound crazy. OK let me explain WHY I want to find out abt the floatation hours for each type of PFD. Coz I want to find if there is any regulation that stated the mandatory floatation hours for each type. First, according the the rule/regulation, we have 5 type of PFD. Ranging from type I to Type V. They must have tested certain floatation hours before they are qualify. So what are the qualify floatation hours in each type. Is there a regulation for that? I do agree that the user might other problem to survive. but let assume that hypothermal is not a problem, and assume also that water and food is not a problem. Then what are the effective floatation hours for each type. I have seen some type actually can immersed 12 hours only and also seen type that can float for 3 days and also type that can float for days. cheers |
