Fire Extingushers

Dear Dipil,
Hai !!!!!!!!!!!
Sorry for delayed answer.
1. Halon fire extinguisher is banned since long as discussed by our friend. But also it is being used.
2. Soda Acid fire extinguishers is in which soda water and sulphuric acid bottle are fixed. When any one can punch the plunger, sulphuric acid bottle is broken and react with soda acid which forms fumes and water contais used for Class A type fire.
3. Foam type fire exinguisher is of two types.
Chemical Type and Mechanical Type.
In Chemical type two chemicals are used in fire extinguisher for making foam when reacts with each other.
AFFF 3 % is foam compound called as Mechanical Foam. It is used with Foam making branch and hydrant water plus Air. Combination of all three (Foam Compound, Water and Air) will strike the surface and falling on the liquid surface.
Waiting for your comments.

Sorry halone extinguisher is not banned.it is banned in using industrial purpuse .but it is still using in aircrafts.
Halone 1301 is the main type of extinguisher used in all aircraft because this is only the non toxic non corossive type.
We can not use dcp or foam because it result in corrosion of aircraft parts cleaning is not possible in some areas of aircraft .co2 is also not used due to replacement of oxygen problem.so halone is not completely banned it is still in use
2) soda acid is not in use due to difficulty in using but it is not banned
3)foam chemical type is in use and not banned

Hi JSK

Cool yaar. Can you please share with us that once emptied out where do you refill it? This is important because we can suie him in International Environment court.

It can be used in INDIA for those who have it, but refilling and production is banned.

Please go through Environment Protection Act.

In Aircraft fire fighting Foam is used. Please do not confuse the readers that foam/ DCP cannot be used. Correct the statement that it should not be used in cockpit or other sophisticated electronic items. During Crash scenario - your Halon is of NO use. Only foam & DCP is used. Kindly go through videos and case studies. I hope you must have seen many real videos eg. concorde crash etc.

Dear you are very much behind in the fire profession. Your both the statement i.e point 2 & 3 are wrong which shows that your update on the same is required.

All new readers request NOT to follow any of the statement given by JSK.

Sorry - but I can not stand any unprofessionalism in HSEF field as this field is for life saving.

any way i am leaving from here because its the time to join Online Safety Community byeeee
and dear neeraj please learn well ok but dont make fun at other if any body is wrong just correct it remeber MAHATHMA GANDHI always he is not a safety professional but his life will teach you that no other courses or training in safety can teach so try to learn his life story and copy it

dear dipil,

i saw these discussions...

according to section 4.4 - Obsolete fire extinguishers of NFPA 10 - 2007, Soda acid & Chemical foam (excluding film-forming agents) are not in use. i have requested our vendor to find the exact reasons & the authorities if any has banned them & revert back. I will update about this later

reg. chemical foam - it is used by chemical reaction.
reg. mechanical foam - in addition to Shailesh, a bit in depth - the operation of the mechanical foam type extinguishers are due to an effect called venturi effect, that is created by the water, which draws the foam into the stream. ie., when the water flows, it sucks the foam in the tube. this sucking effect is called Venturi effect, technically. inside, it has a metering valve, that controls the percentage of concentrate to ensure a proper mixture. the foam & water mixture passes through a nozzle, where air is introduced at the nozzle to form the finished foam.

i think this is not your exact requirement, however, after seeing the discussions, i though of adding more.

dear neeraj,
thanks for being online with us on board. we r here to support you on your stand. lets join together.
however, i was not aware about aircraft & now i got a point to learn & nice explanation.

dear ragu,
your explanation was exact the same reg. the CCA of US. however, i was not aware about EPA & thank you for the data.
adding to that - Halon 1211 is typically used in portable fire extinguishers & 1301 is used in installed systems.
however the production has been stopped in US, it still remains as an approved agent in existing systems.
now a days there are substitutes for halon. Trade names - INERGEN, FM 200, FE 36. out of this, FE 36 is aimed for replacing 1211, which was used primarily in the portable fire extinguishers.

Dear all,
Nice to see the participation in the discussion.
I would like to add something to the discussion.
We have recently procured a mini tender with ultra high pressure pump which operates at 100 bar pressure & 150 lpm throw.It makes water into very fine spray just like fog in winter so it can be used on live electrical equipments also.It has got very good cooling effect.we hv tested it over B class fire also just as demo & it was effective.It also has 200 lt foam capasity also.& due to its small size it can be taken to narrow areas too.

I really appreciate all this discussion..............but I think the discussion should be always supported by LEGAL PROVISON for any Topic...............then it will become best

Halon is banned...............Soda acid is banned................Please give me the Notification link

Dear All,
Great Discussions so far.
I missed this thread so far.
The new things to learn are aircraft safety.
To the best of my knowledge in certain applications in Denence they are still using Halon.
I am not very sure, but I can find out for the group.
Neverthe less, halon has certain environmental impacts.
This thread has initiated a lot of questions for me to refer law and get updated.
Thanks again.
