cylinder which has once been used for storage and
transportation of coal gas shall be used for filling with any
other gas. |
|
|
( 3) |
No
cylinder shall be filled with any gas that is capable of
combining chemically so as to endanger its
serviceability. |
|
20. |
Storage of cylinders.- |
|
|
( 1) |
Cylinders shall be stored in a cool, dry, well
ventilated place under cover, away from boilers, open flames,
steam pipes or any potential sources of heat and such place of
storage shall be easily accessible. |
|
|
( 2) |
The
storage room or shed shall be of fire resistant
construction. |
|
|
( 3) |
Thin
wall cylinders such as liquefied petroleum gas cylinders and
dissolved gas cylinders shall not be stacked in a horizontal
position. |
|
|
( 4) |
Cylinders containing flammable gases and toxic gases
shall be kept separated from each other and from cylinders
containing other types of gases by an adequate distance or by
a suitable partition wall. |
|
|
( 5) |
Cylinders shall not be stored under conditions which
will cause them to corrode. |
|
|
( 6) |
Cylinders shall not be stored along with any
combustible material. |
|
|
( 7) |
Empty cylinders shall be segregated from the filled
ones and care shall be taken that all the valves are tightly
shut. |
|
21. |
Electrical installations.-In premises for filling and
storing flammable gases in cylinders all electric meters,
distribution boards, switches, fuses, plugs and sockets,
electric fixed lamps, portable hand lamps and motors, shall be
of flame proof construction conforming to appropriate Indian
Standard Specifications or such other specification as are
approved by the Chief Controller and shall be effective
earthed. |
|
22. |
Purity of gas.- |
|
|
( 1) |
Compressed gases shall be free from impurities which
are likely corrode the metal of the cylinder or form an
explosive substance with it or cause the gases to decompose or
explode. |
|
|
( 2) |
The
gases shall be as dry as is possible and in no instance shall
the aqueous phase separate when a liquefied gas is cooled to
00 C. |
|
|
( 3) |
Before filling any cylinder with gases like carbon
monoxide, coal gas, hydrogen or methane, the gas shall be free
from hydrogen sulphide and other sulphurous impurities as far
as practicable. The moisture shall be less than 0.00 g/m02 of
gas at normal temperature and pressure. |
|
23. |
Cylinder subjected to the action of fire.- |
|
|
( 1) |
A
cylinder exposed to fire shall not be used unless it has
undergone proper examination and Hydrostatic/hydrostatic
stretch test. If deleterious structural changes in the
material due to the action of heat of the fire is apprehended
to have taken place, the cylinder shall have to be subjected
to proper heat treatment, followed by hydrostatic test or
hydrostatic stretch test, as the case may be, before the
cylinder is taken into use. |
|
|
( 2) |
Dissolved acetylene cylinders which have been damaged
by fire shall be condemned and destroyed by an experienced and
competent person. |
|
24. |
Ownership of cylinder.-A cylinder filled with a
compressed gas shall not be transported unless it was charged
by or with the consent of the owner of the
cylinder. |
|
25. |
Re-testing of cylinder.-A cylinder for which prescribed
periodical re-test has become due shall not be charged and
transported until such re-rest has been properly
made. |
|
26. |
Owner's record.-The owner of a cylinder shall keep for
the life of each cylinder, a record containing the following
information regarding each cylinder, namely:-- |
|
|
( I) |
Cylinder manufacturer's name and the rotation
number; |
|
|
( II) |
The
specification number to which the cylinder is
manufactured; |
|
|
( III) |
Dte
of original hydrostatic test/hydrostatic stretchy
test; |
|
|
( IV) |
Cylinder manufacturer's test and inspection
certificates. |
|
|
( V) |
Number and date of letter of approval granted by the
Chief Controller. |
|
27. |
Conversion of cylinders.-Gas cylinders designed and
approved for filling with a particular gas shall not be used
for filling with any other gas unless specific approval is
obtained from the Chief Controller. |
