DEFINITIONS SLIDE 1



1)Gas cylinder: Gas cylinder" or "cylinder" means any closed metal container having a volume exceeding 500 ml but not exceeding 1000 liters intended for the storage and transport of compressed gas.



2)Composite cylinder: It means a cylinder made of resin impregnated continuous filament wound over a metallic or a non-metallic liner.



3)Compressed Gas: It means any permanent liquefiable gas or gas dissolved in liquid under pressure (or) gas mixture which in a closed gas cylinder exercises a pressure either exceeding 2.5 kgf/cm2 abs (1.5 kgf/cm2 gauge) at +15°C or a pressure exceeding 3kgf/cm2 abs (2 kgf/ cm2 gauge) at + 50° C or both including cryogenic liquids

DEFINITIONS SLIDE 2



4) Cryogenic liquid: It means a liquid form of permanent gas having

normal boiling point below minus150°C; i.e. a gas existing in the liquid form with a boiling point of -150 Celsius. 

5) Critical temperature: It means the temperature above which gas

cannot be liquefied by the application of pressure alone. 

6) Pneumatic test: It is a test in which a gas cylinder is subjected to a pneumatic pressure equal to the pneumatic test pressure or working pressure, as specified in the manufacturing code.

INSTRUCTIONS FOR SAFE HANDLING

CHAPTER 2 : GENERAL PROVISIONS 

1)Filling Possession, import and transport of any cylinder:



The gas cylinder should not be filled with any gas unless the cylinder and valve is being constructed based on a standard mentioned in (Schedule I )by an order issued by the Chief controller.



Welded low carbon steel cylinders for low pressure liquefiable gases manufactured to IS:3196



Seamless Aluminum Alloy cylinder manufactured to ISO 7866 & IS 15660



There are 13 countries with different origins relating to schedule 1



The test and the inspection certificates issued by the inspection authority in respect to any cylinder and its valve should be made available to the Chief controller



To obtain the approval the following information are required



a) The number of cylinders and their serial numbers



b) Name and address of the manufacture of the cylinders

1)Filling Possession, import and transport of any cylinder: (Contd) 

c) Previous approval if any



d) The test and inspection certificates in relation to the valves fitted or to be fitted to the cylinder.



e) Scrutiny fee (Inspection or Examination fee)



In case of foreign manufacturer’s are requesting for their approval additional fees shall be paid as per schedule 5 for the physical evaluation of the unit.

Valve Specifications 

Valve fitted to gas cylinder shall comply in all respects with the following specifications, namely:-



In respect of industrial gas cylinder and CNG on-board cylinder, IS:3224; In respect of medical gas cylinder, IS:3745;

In respect of cylinder used with breathing apparatus, IS:7302 as amended from time to time; In respect of auto LPG container IS:15100 In respect of small refrigerant cylinder IS:12300

TYPICAL ARRANGEMENT FOR FIXING THE VALVE

Valve Specifications (Contd) 

The Valve fitted in the Carbon Dioxide cylinder shall be provided with a safety release consisting of softened copper disc so arranged as to burst at a pressure between 200 Kg/cm2 and 220 Kg/cm2



Valve for cylinder containing flammable gases not listed in IS: 3224 shall have outlets provided with left handed screw threads for the pipes or other connections.



All other valves shall have outlets with right-handed screw threads.



The design of spindle-operated valve shall be such that when fitted to the cylinder, it should be impossible to withdraw the spindle under normal operating conditions.

Regulations of the Cylinder

Safety Relief Devices 

The cylinders manufactured in India if they contain the safety relief devices those devices should be manufactured and maintained as per the standard IS: 5903



Cylinders which contain poisonous gases should not contain any safety relief devices. The poisonous gases include (Carbon monoxide, Hydro-cynic acid, Hydrogen chloride, Hydrogen bromide, Hydrogen fluoride, Sulphur dioxide etc)



The Cylinders which are manufactured in foreign countries but are approved to be used in this country if they are fitted with any Safety relief devices which are to be maintained in the same manner as they were originally made in abroad.

Marking on the Cylinders 

1) Clear and permanent labelling (Probably on the Shoulder of the cylinder)



2) Kindly avoid the name plate affixed to the cylinder by the means of soldering because there are chances of that getting corroded leading to a gas leakage.



3) Near to the marking some space has to be provided for placing the test date obtained during the periodic inspection.



4) The markings can also be made with letters and numerals but it should be easily readable.



5) Marking of the expiry date in the cylinder is highly important.

Markings on the Valve



1) All the markings made in the valve should be clear and readable



2) Valve specifications



3) Year, Month, and the Quarter of the Manufacture



4) Manufacture’s symbol



5) The name or the chemical symbol of the gas for which the valve is to be used



6) Inspectors stamp

IMPORTATION OF CYLINDERS a) IMPORTATION BY SEA 

1) The agent who is sending the cylinders from abroad should inform the

conservator before 48 hours of its intended arrival at the port. 

2) A person willing to import cylinders filled with any compressed gas shall produce his license personally or can also produce his license in the form of an agent to the customs collector for importing such gas cylinders, valves, or LPG

regulators. 

3) Only if a Customs Collector permits any cylinder can be imported inside the port. Each and every item which is to be imported should be lawfully correct only then it can be landed.

IMPORTATION BY LAND AND AIR



Importation by land.- No gas cylinder filled with any compressed gas, valves and LPG regulators shall be imported by land save with the previous sanction in each case, of the Central Government and under such conditions and restrictions as it may impose.



Importation by air.—No cylinder filled with any compressed gas shall be imported by air save with the previous sanction in each case of the Director

General of Civil Aviation.

EXAMINATION AND TESTING OF CYLINDERS 

Gas should not be filled in any cylinder unless the cylinder is being subjected

to hydrostatic test . The test can also be undergone as per the writing provided by the Chief controller 

As per Schedule 4 the testing station should provide or mention the facilities

in the testing station with a scrutiny fee as mentioned in schedule 5. 

Initially the cylinder testing station may give them a period of one year and this period may be extended to a period of 5 years based on the ISO accreditation certificate issued by any agency.

CONDEMNING OF CYLINDERS 

Any Cylinder which fails to the periodic test or examination or if it is found to be unsafe to use or if it is used beyond the expiry service of life should not be refitted with any gas and should be destroyed by flattening it as a whole or being cut into pieces. So that they are not allowed to re as a whole by welding to form it as a cylinder as specified in IS:8198.



All the markings on the cylinder should be defaced before it is being destroyed.



History sheets or records of the closed cylinder shall be sent to the chief controller in writing on the 1st January , April, July, and October every year

FILLING AND POSSESSION 

A license is required for filling and possessing a cylinder to be filled with compressed gas.



No person can fill any cylinder unless it is approved and it es the examination and test specified in the rules



The working or internal pressure in any cylinder charged with a permanent gas shall not exceed two-third of the test pressure.

ACCIDENTS AND INQUIRIES 

To the chief controller or the controller whose jurisdiction the area falls by Fax, email the occurrence of the incident should be reported immediately, this should be followed by a letter within 24 hours.



The District Authority concerned, the officer in charge of the nearest police station having the quickest route should also be informed with the incident.
