Dear All

As per ANSI Z49.1:2005 Oxygen Gas Cylinder in Storage Shall be kept with a safe distance of 6.1meters from combustable gas cylinders.

As per Gas Cylinder Rules 2004, Chapter 2, General Provisions, Section 21:Storage of cylinders: 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.

Gas Cylinder Rules 2004 is not specifying how much distance and both the above is related to storage of gas cylinders only.

No my question is:

1. What should be the safe distance between fuel & Oxygen while storage as per statues in India? Which is the latest applicable Act/Rule in India regarding the same?

2. What should be the safe distance while transporting fuel & Oxygen as per statues in India? Transporting in same trolley is safe or not?

3. What should be the safe distance between fuel & Oxygen while in use as per statues in India?

Request to put some lights into the topic. If you are not having updates of Indian Statues, please let me know the same as per any other legalization.

1.While storage 10 feet distance shall be practically maintained between fuel and Oxygen cylinders.

2. NEVER KEEP FUEL & OXYGEN IN THE SAME VEHICLE FOR TRANSPORTATION. So no question of safe distance arises. It is not safe to transfer fuel & Oxygen cylinders in the same trolley. Trolley designed for two cylinders shall be used to keep both the Oxygen & Fuel cylinders upright, held with chain while in use.

3. No specific distance is mentioned in statues while in use. Other precautionary measures like leaks around the valve stem, leaks from regulator, fuse plug,providing hoods over the cylinder to prevent fall of hot spatters etc.shall be ensured as better prevention.

Dear Sir

Thanks for providing me the NFPA 55 standard... The table 2-1.5 is basically for Toxic Gases, if I understood rightly wheras in our case both LPG and Oxygen are not toxic... However this document also clearly mentioning about a distance of 6.1m...


Thanks for your inputs into the thread. I just want to know whether this 3meter distance is safe while storage where all the document is saying safe disatance to be maintained is 6.1m.. This you say in view of practicallity only na... Please have a look into the trolley in the attached file and give your suggestion... Whether this transportaion is safe... Somethime keepin both cylinder in this same trolley and using at site...

@Yadvinder Sharma

First of all warm welcome to the forum.. Hope we will get a lot to learn from yourside...

Now my purpose is that I have raise objection against the existing practices going on in our plant regading the storage of cylinders... Its not in main storage, but in site wise storage... So the management is not convinced by my inputs.. So thought of study more about it before giving further proposal... So requesting you to please go through the attachment and give your valuable comments...

@ All: Please go throught the attachment and give value addition to the thread please...

@Abhay: Thanks for your inputs...

Thanks in advance to all...

Dear Hansa
As per my view, it's ok to transport the same in this bobcat... What missing is that it's not secured properly... If this cylinder by keeping in vertical and properly secured, I think no more issues...
Lets wait for experts advice... Hope to get reply's...

On 29-06-10 a news paper reported this case (clipping in my storage): In Bhayandar (East) in a welding unit in Kasturi Ind Estate Jagdish Sahani was rolling the cylinder by his leg when cylinder burst. His leg dismantled and was thrown 300 meter away. Police took 3 hrs to find the leg. His another leg was injured to an extent that it had to be amputated in the hospital. Have not seen follow up news on what happened next

Dear friends,
Interesting discussion.
Solve the problem :
Oxygen cylinders in storage will be separated from fuel gas cylinders or combustible materials (especially oil and grease) by a minimum distance of 6 meters (20 feet) or by a noncombustible barrier at least 1.8 to 2 meters high having a fire resistance rating of ½ hour.
This is only for bulk storage, not for cylinders in service. Even at site if storgae is necessitated this seperation is essential. You make a combined cage, have a fire resistant partition between O2 and fuel gases and again sepereting full and empty cyinders and have sign boards (Fuel gas - empty - full, O2 Empty - full etc. ) you are safe with your storage.

@ Hansa.
Thank you for the information. When & where did that happen? I am interested in knowing if the victim received compensation and rehabilitated?
For information of all members: I edit a bimonthly on Occupational Health & safety in Gujarati since last 20 years. Those interested may request me for sample copy. April issue in press.

Interesting Discussion.
Good evening to all.
For the picture attached by Hansa -
1.The equipment being used for transporting the cylinder seems to be a Earth /Soil handling equipment.
2.From safety point of view, equipments should only be used for the purpose they are ment for and not for other purpose.
3.The Cylinder being transported is not secured.
4. A question - is the driver aware of the hazards of the material (Chlorine) he is handling and is he competent enough / trained for such material handling?
5.The cart is hydraulically operated. The hydraulic system may mal function or may be mis operated, causing toppling of the cylinder.
A simple cart can be fabricatted with arrangments for securing the cylinder and may be attached to a tow car or any other media of transport.

Dear Hansa,
Thanks for the welcome. Yes, I was not able to visit the site due to personal reasons. It seems that I have missed a lot of discussions.
This topic of discussion is very interesting and will help us a lot in developing and implementing a safe practice for cylinder handling at the job site.
Can you please take some pain to find out the details and investigation reports and photos if any of the incident that you have mentioned earlier. Actually the wrong practice of rolling the cylinders and pushing by legs is followed in every industry. If you can share the details, I can use it to motivate the concerned people to follow the safe practices.
Dear PTRC: Request you to pls. share the details. It will really help.

Dear Hansa,
the photo for Cl2 carrying is a wrong practice.
The JCB is not to be used for carrying such type of cylinders.
It must be hooked and carried only in cage type of trolley made for cylinder transfer.

Dear All

Transportation of chlorine cylinder through terex bucket is most unsafe.
Transportation should not be done in vertical postion.
Due to sudden jump of terex at uneven place and fall of cylinder can create major emergency.
Transportation can be done in a truck in vertical postion but with after tying with suitable ropes.
There should be good trolley attached with terex of suitable height equal to cylinder with tying arrangement
.if transportation is to be done in terex then the cylinder should be in horizontal postion with side supports and tying arrangement.
Under no circumstances it should fall to the ground.
