Dear C.R.Siani,
Your clearly addressed on your investigation report that 100% its happened because of manufacturer defect.
Did you notice this issue to manufacturer?
Did you read the manufacturer O&M manual for FBA?
Did you have the proof of training documents that you provided to your employees on this equipment?
Are you sure it will not happen in ISO marked FBA’s?
How do you check the FBA working system – Who is responsible to check?
For your info - FBA’s are generally reliable in performing the intended function so long as the device is used according to the manufacturer’s instructions. If an end-user neglects or ignores the manufacturer’s stated or published safety and maintenance recommendations, that person is an accident waiting to happen and no accessory safety device will prevent all possible accidents. As one who has handled accident litigation cases for the past several years, I can state unequivocally that most oxy-fuel accidents are caused not by equipment malfunction, but by user neglect, impatience or lack of experience in using equipment safely.
Do me a favor provide me a details of FBA that you used on your plant/work site. I will talk to the manufacturer get some information which will help to educate ourselves.
According to your report - Action required should include the below points:
Manufacture manual should be available on-site or practically accessible; whoever operating the equipment should go through the O&M manual prior to operating the equipment – (It should be supervisor and EHS personnel’s responsible).
Appropriate training should be provided to all personnel’s whoever involve with this task – As per manufacturer requirement (Its should be management and safety responsibility).
Choose the right materials for the task
manufacturer instruction should be followed whenever operating the equipment
I don’t think it’s a small issue if it’s really a manufacturer defect am sure I’ll bring that issue to next level without involving you please provide me a details that’s what I need from you.
I’m eagerly looking forward your reply if you’re not comfortable to share the info in social network – I’m available at
Thanks in advance.

Dear All,
FBA should comply IS 11006-1984. But i never seen any IS certified FBA in India. Most of us using FBA which normally act just as a NRV. Some of the Branded items are complied with EN 730. At the same time. they are manufacturing the product with different serial number which is not complying IS or EN code. So, we should aware and careful while selecting a product.
Thanks

Dear Raghu,
I would also like to add one more point here which i doubt might have also been there. It is also to be investigated that was it repaired in-house or by any one who is not authorized to do so.Its maintenance history should also be checked along with points that you mentioned above.
Also if you have FBA of same make used by other contractors, should also be checked for the same.

That's the reason we are insisting to use the standard product of Flash Back Arrester while doing cutting and welding activity. If the Flash Back arrester is not working properly then it may endanger the lives of so many people working around the area.

To the extent I know about FBAs, I think Hansa Vyas's hunch is right--more of an O&M issue than related to the Manufacturer.
We Indians are known world-over for what we call 'Jugaad'--improvising.
But I know that, many times, we go overboard even when the necessary Tools / Systems / SOPs are in-place.
Anyway, let's wait for Raghu's inputs.

Dear Raghu,
The FBA shown in the website is not FBA. It is just a NRV and am sure it is not ISI certified. The FBA should have
1. Flame arrestor
2. NRV
3. Temperature sensitive cut-off valve
4. Pressure sensitive cut-off valve
Pls let me know if i am wrong. and looking forward comments from our senior members.
