3. • In SCBA the wearer carries all the means of
respiration in an irrespirable atmosphere.
• The wearer using this apparatus can move and
work in atmosphere consisting of noxious and
poisonous gasses ,what ever their %.
• It last . depending upon size.

4. • A SCBA is of in which the
oxygen supplied to the wearer is not lost to
atmosphere during exhalation but it is reused
by him after the exhaled air is feed up of the
CO2 by chemical absorbents
• Hence it is also called
.
• SCBA used in our mines are two well known
makes :
1.Proto self contained compressed
O2 apparatus.
2.Drager self contained compressed
O2 apparatus.

11. • A Reviving apparatus is used to administrate
to :
1)An unconscious person
2)Whose breathing is considerably feeble for some
other cause.
• The treatment is given to the patient by the
rescue team at a zone free from noxious gasses
or at the fresh air base.

a.Two cylinders ,each containing
charged to 120 atm.
b.Reducing valve
c.Hand control valve
d.Dial calibrated from 0 to 30 lit per min
e.Flexible breathing bag
f. Corrugated tube
g.Pressure gauge and main valve

13. • Figure of reviving apparatus
• Other manufacturer of reviving apparatus is
by the firm of Drager is known by the
trade name pulmotor.

14. Special features of dragger apparatus
:
• It gives a if the if the
apparatus is used with the cylinder valve
closed or if the cylinder is empty.
• A rechargeable can be
used for training purpose.
• Breathing bag is protected on all sides.
• The reduces the pressure to
tolerable working pressure of

15. • This apparatus is used by the wearer to
protect him self from poisonous gasses
containing mainly CO.

16. Anhydrous to remove water vapor.
: It acts as a catalyst which changes CO to
CO2
Cotton wool to remove dust.
to remove ammonia
to remove sulphureted hydrogen
Impregnated activated to remove organic
matter and acidic gasses.

17. • A self rescuer is essentially a gas mask
in a simplified form without the
corrugated hose tubing and the mouth
piece is directly attached to the canister.
• Wt. is
• The chemicals are same as those used
in the Gas mask.
• The wearer is protected against CO if its
vol. doesn't exceeds by in the air to
be inhaled, If the O2 is sufficient to
