The following is
some useful information and advice that may help you decide
What to Wear for Personal Safety
(and the Difference Between Lifejackets and Buoyancy Aids)
Some
Definitions
CE Mark
We, as other manufacturers, can only sell lifejackets, buoyancy aids and safety
harnesses that have been tested to the latest CE European specifications and
carry the CE mark of approval, this ensures
that they meet the new European Standards (similar to the BSI kite mark)
Newton
A Newton is a measured unit of force. 10 Newtons are approximately equal to
1 Kilo (2.2 lbs) of buoyancy. They are the new EC standard. The higher the
Newton number, the more buoyancy provided.
The buoyancy quoted is for adult
sizes only. Smaller sizes have proportionally less buoyancy.
There
are four levels of Buoyancy Ratings
|
275 NEWTON LIFEJACKET 62lbs/28kg buoyancy
Suitable for swimmers and non-swimmers
- A
high performance device for offshore and severe conditions, when maximum
protection is required or where heavy waterproof clothing is worn
- They
give improved assurance of safety from drowning to people who are not able
to help themselves
- While
they cannot be guaranteed to self-right an unconscious user wearing heavy
waterproofs, the buoyancy they provide should ensure they will in the great
majority of cases
|
|
|
150 NEWTON LIFEJACKET 33lbs/16kg
Suitable for swimmers and non-swimmers
- For
use in all but the most severe weather conditions
- They
will give reasonable assurance of safety from drowning to people who are not
fully capable to help themselves
- May
not immediately self-right an unconscious user wearing heavy waterproof
clothing
- Equivalent
performance to previous BSI approved jackets
|
 |
|
100 NEWTON LIFEJACKETS 23lbs/11kg
Suitable for swimmers
- They
will give reasonable assurance of safety from drowning in relatively calm
waters
- Not
guaranteed to self-right an unconscious user wearing heavy waterproof
clothing and should not be expected to protect the airway of an unconscious
person in rough water
|
 |
|
50 NEWTON BUOYANCY AID 11lbs/5.5kg
Only suitable for competent swimmers
- Sheltered
water use where close help is at hand
- Only
provide support to a conscious person who can help themselves
|
 |
So
that’s the definitions - Some
practical considerations
|
150 newtons lifejacket
– available as manual or auto inflation
easy to wear, not bulky, not
too heavy, to work when you are in the water the lifejacket must be fully
inflated, the buoyancy pushes you on to your back to help keep your mouth clear of
the water, you would find it difficult to climb back in a boat unaided.
( if there is a chance you may
fall in unconscious eg from the boom on yacht etc banging your head, use an auto
inflation – you will not be able to inflate a manual inflation life jacket if
you are unconscious).
When the life jacket has been
inflated you will need to deflate and order a new cartridge
This lifejacket is not designed
for someone in a dinghy who is liable to fall in or capsize often.
|
100 newtons lifejacket
Tends to be more bulky,
although it is usually lightweight. Again, the buoyancy is pushing you on
to your back to help keep your mouth clear of the water.Likewise, we would suggest, if
buying for a child under 5-6yrs, you should maybe buy a 100N lifejacket, even if they can swim,
because they may well receive quite a fright if they fall out of a boat into cold
water, and may panic which might affect their swimming.
|
|
50 newtons buoyancy aid
This is an aid to swimming,
since the buoyancy is round the body rather than just on the chest front.
It is easy to wear, not bulky,
cut high so it is easy to sit down, and you are manoeuverable in the water, and
climbing back in a boat after a capsize is not a problem.
|
|
However it is
only an aid to swimming and for
competent swimmers
Points for
thought
-
if
you can't swim you need a lifejacket
-
if
you are under a capsised boat the more buoyancy you have on, the more
difficult it is to swim out from under the boat.
-
in
a dinghy, the collar of a 100N lifejacket maybe a hindrance, eg getting
caught on the kicking strap etc
We realise this is a very
important subject and if you would like further advice please contact us.
