place, Acetylene is fixed light, and
not like kerosene, one that is handled
about, and that by persons of all ages.
The movable Kerosene lamps are with
IN reach even of Young children who
have no sense of danger. Moreover.
Kerosene lamps commonly are made
of < lass and IN the nature of things
subject to EASY breakage.
Then IN the case of Acetylene. the
liked flame IL always many feet from,
the source Of glass supply, this being
communicated through small cool
pipe only as used. Ia the lamp. on
the contrary. the flame is within
few inches from a quart or so of high
ly infiammable oil, an inflammable
wick connecting them. Consider for
"A moment the combination: inflam-
Unable oil, contained ia fragll, hold
er, surmounted by fire, and all car.
rled freely about. A stumble or iostle
may cause the vessel, so well equip
ped for cOuhagration, to fall with
the most serious consequences. Lamps
too are carelessly placed on shelves or
on Insecure stands liable to be over
turned. Metal lamps are scarcely
safer than gas, as metal conducts heat
to the OIL receptacle. making explo-
sion liable.
Every one of the above hazardous
elements (hame excepted) is absent in
Acety lene gas. with the liability to
acciuent lessened in proportion.
The fact that Acetyleue gas is
made only as used, renders it much
safer than illuminants that are stored
IN cans or barrels AS required The
danger liable from stored oi Is is we'll
shown by case, reported in the tel
egraphic dispatches June Stb last,
from Pittsburg, as follows:
Three children named Watts met
death in Allegheny last evening bv
the explosion of a can of OIL Their
clothes were ignted and the children
burned so terribly that they died in
Il short time. The children were
playing in an clubhouse in the yard,
and one of them struck match,
which dropped into a can of oil, and
an explosion followed Instantly"
Lastly, the heat of the Acetylene
flame (see under y is much less than
that of kerosene, thus lessening the
danger of lighting wood, curtains,
shelf papers or any combustible sub
stance over the flame.
SAFETY Of Acetylene-gdS. as 5aSed on its
small 6Utk for Il gireH candle pOWer,
'chen compared tcith common gas.
That common city gas is reasona
bly, safe is shown by the last national
census, which places the nations gas
bill at the enormous sum of $40. .S36,
400 every year. Such figures speak
we'll safety if not for economy. That
Acetylene is much safer, it may be
left with gas filter to show: it Is
wholly question of size of burner
tips as governing the required flow
of gas.
Thus to obtain All rs candle-power
flame of common gas. > foot tip
passing > cubic feet of gas per hour
is the standard. But for - candle
power flame of Aaety ylene, "a foot tip
passing cubic foot of gas per hour
is the only one furnished. The diff
ference in bulk of gas used is there
fore as to II in favor of Acetylene.
How would this difference apply in
case of Acetylene accidentally escap
ing into room. in producing an il
hltA'iS uilANNtt Vi All duu SdS. Let
us take II bed room 10 Y 1t x9 feet,
having 1860 cubical feet contents
and lighted by two 25.candle Jets.
Blow out both flames, leaving the gas
on full and nO:e what follows. The
two half-fOot jets will pass exactly
one cubic foot of gas into the room
every hour, or ten feet from 10 p. m.
until Sam. Two corresponding Jets
(same candle power of common gas
would pass that volume of gas every
40 minutes.
As to the ignitabIlitv of Acetylene
gas, the first or lowest stage at which
this occurs is reached when there is
present one part of Acetylene to 20
parts of air.
