.1.7 Personal Flotation Devices
(
PFDs
)
There must be one United States Coast Guard a
pp

wearable personal
f
lotation device o
f

y
our boat. The PFDs must be in

A

three PFDs
(
two wearable and one throwable
)

PFD T
y
pe I, Wearable:
This offshore life
j
acket has the
g
reatest buo
y
anc
y
. It is
eff
ective
f
or all waters where rescue ma
y
be dela
y
ed. Its
desi
g
n allows
f
or turnin
g
most unconscious persons in
the water from face down
p
osition to a vertical or face-u
p
position.

PFD T
y
pe II, Wearable
:
This near-shore buo
y
ant vest provides less buo
y
anc
y
than a T
y
pe I PFD. It is intended for calm inland waters
o
r waters where there is a chance o
f
quick rescue. It turns
its wearer to a
f
ace-up position as does the T
y
pe I PFD,
b
ut t

s not as pronounce
d
as t
h

Ty
pe
I, and it will not turn as man
y
persons under the same
c
onditions as a T
y
pe I.
(

)
PFD T
y
pe III, Wearable
:
C
lassified as a flotation aid, this PFD allows wearers
to place themselves in a vertical or
f
ace-up position in
the water. T
y
pe III PFD has the same minimum buo
y
-
anc
y
as a
Ty
pe
II
PFD

.2.2 What is Carbon Monoxide?
C
arbon Monoxide is a hi
g
hl
y
poisonous
g
as
f
ormed b
y
the
c
ombination of carbon and ox
yg
en. Commonl
y
referred
to as
CO
, its chemical
f
ormula is
C
f
or carbon and
O
f
or
ox
yg
en.
CO
is a colorless, odorless, and tasteless
g
as
that, b
y
itself, cannot be detected b
y
human senses. C
O
di
ff
uses in the air much more rapidl
y
than other
g
asses
that are detectable b
y
the human senses. The wei
g
ht o
f
CO
is about the same as air so it does not rise or fall like
other
g
asses but will distribute itsel
f
throu
g
hout the boat.
CO
is produced an
y
time a material containin
g
carbon is
b
urne
d
.

g
asoline, diesel

uel, or propane. All carbon
based
f
uels produce var
y
in
g
amounts o
f
CO
, depend-
in
g
on their carbon content. Gasoline is hi
g
h in carbon
and, there
f
ore, produces lower levels o
f
CO
. However,
the exhaust o
f
all en
g
ines and
g
enerators as well as an
y
o
p
en flame device,
p
roduce C
