When a light chitustivié ‘aioeda ‘ds thrown out on the eros of the water,
it spreads out to a thiclmess of one molecular layer. . The rate at which this
takes place depends upon the manner or force with which the liquid is dis-
charged, the viscosity, the speed of the wind, and the peculiar properties of
the matter itself, as: wert. as the course and “pee of the: the

. of it floats out over a radius of thirty feet, and it will burn brightly for
four to seven minutes. The distance the fire spreads will depend -upon the wind,
to a great extent. The wind will, of course, cause the liquid tao spread out
thin and burn fast, and the more it thins out the less time it “a take to
burn up.in one spot and the less heat it will throw, . .

The best. method of escape from this danger is as but it takes courage
which our men have proved they, possess, The longer a person can remain aboard ~
ship, the less time he will have to remain in the water and in the fire,

RKREP CLOTHES Qi

Tt is Beat taloeekat to ‘penetn completely clothed when it is necessary to
go into fire-covered water, All clothes are needed except, of course, heavy
coats, shoes or sweaters and heavy trousers. But light shirts, duck trousers,
hats and socks and light-weight shoes should be kept on. The duck trousers and
shirt have a certain amount of buoyancy as they collect and hold air next to
the body and the hat and socks will furnish protection against burns. ,

"MAKE WATER WINGS

Making water wings is very important, Duck trousers and shirts can be
used to float on. This is done in the following manner: remove the, trousers
and tie up the legs near the cuffs and button all buttons; in a circular motion,
swing the trousers through the air away from the body and hold the top of the
trousers open. They will then fill up with air and can be used as water wings,
if twisted into a "V" to Araw the top together. When the air escapes, they can
be re~filled, In this way a person can keep afloat for hours with little effort,

When thrown into the water a man has little choice as to the metho of
entry, but ‘when there is a choice possible on where to leave the:.vessel, he
should dive from the winiward side (into the wind) and swim under water against
the wind as far as possible, Upon coming up to the surface he must throw his
arms high in a whirling motion to push away the fire above and get air to duck
again and go on under wator out of the danger spot. ee

Upon getting out of the middle of flaming area he can go on with a short
breast stroke and swimming slowly, first bringing up fresh water in front to
push the flame shead and away with a forwari and upward notidh, and then advan-
cing through the water on a short draw back and kick, ‘This modified breast
stroke enables aman to push flames away from his face and the fumes away from
his nose and mouth. . Demonstrations of this are given by aquatic fire-eaters
and fire divers in college and professional shows.
