Dear dipil,
1. Halon Extinguishers still can be used or it's banned and Why?
Answer:::Under the Clean Air Act (CAA), the U.S. banned the production of halon and import of virgin halons 1211, 1301, and 2402 beginning January 1, 1994 in compliance with the Montreal Protocol On Substances That Deplete The Ozone Layer. Recycled halon and halon inventories produced before January 1, 1994, are now the only sources of supply.
EPA's final rule published March 5, 1998 (63 FR 11084), bans the formulation of any blend of two or more of these halons with one exception. An exemption is provided for halon blends formulated using recycled halon solely for the purpose of aviation fire protection, provided that halon blends produced under this exemption are recycled to meet the relevant purity standards for each individual halon. A fact sheet summarizing this rule is also available from the Stratospheric Ozone Protection Hotline.
Now a days we use Recycled Halon:
The term "critical use" is used by HRC to identify priority uses of recycled halon. A halon use is considered "critical" when a need exists "to minimize damage due to fires, explosions, or other extinguishing agents, which would otherwise result in serious impairment of an essential service to society or pose an unacceptable threat to life, the environment, or national security even though all other appropriate fire protection measures have been taken."
2. Soda Acid Type Extinguishers still can be used or it's banned and Why?
Sorry no idea. . .
3. Chemical Foam Extinguishers still can be used or it's banned and Why?
Sorry no idea
Wait for commands

Dear Dilip
Raghu has already given reply to Q1
Answer for other 2 is as under:
Soda Acid and Foam extinguishers (Chemical) are NOT BANNED but as per International fire Associations - they have been asked to remove from the fire service. There are different versions for the same but actual it was that there were many incidents following wrong usage of Fire extinguishers as there were many which were operated upright and many inverted types.
Hence all inverted fire extinguishers were removed from fire services - but you will still find many soda acid and chemical foam extinguishers in Govt. Sectors like railways PO etc.
1978 edition of NFPA has mentioned in their code " All inverted type extinguishers shall be removed from fire services".
For further information - even cartridge type operated extinguishers have been outdated since last many years. Only stored pressure type are to be used.
Please check NFPA-10.
Hope the query is cleared - for any further info - please feel free to contact 09925153646.

@ Neeraj
Thanks a lot for your valuable reply and helping in solving the issue... I have noted down your number and will call you surely when in need...
I have undergone one Fire Prevention and Fire Fighting training recently... In which the faculty was explaining about halon extinguisher ... He was emphasising that Halon is the best extinguisher which we can use, and normally you can see in vehicles and most of the kitchens in Europian countries... As I was not sure about the facts behind Halon I not get more chance to debate with him on the topic at that time...
As per Raghu's post and refering in net it was found that Halon can be used only for critical operation which is laid out by HRC...
What all areas will comes under this Critical Use? Inside vehicle or a kitchen will comes under the class of critical use or not?
Once again thanks all for the participants and looking to hear more on the topic...

Dear Dipilji ,
After discussing with my S.O. Pls find answer to your Ques.No. 3 :
Chemical Foam Extinguishers still can be used or it's banned and Why?
Chemical foam or Aqueous Film Forming Foam or AFFF (pronounced A-triple-F) is not banned , in the last 15 years become one of the most popular fire extinguisher in chemical industry . very Suitable for Class B (flammable liquids such as petrol, hexane , methanol ,spirits, diesel) and can be used for for Class A fires (wood, paper, material, cloth, etc) .It should never be used on live electrical equipment .

Dear Dilip
Halon extinguishers and Total flooding system can be used in certain developing countries upto 2012. BUT the production and refilling is BANNED throughout the world.
Yes at one time and even today there is no comparision to Halon as far as fire extinguishing is concerned but as it has damaging effect on Ozone layer it has been banned by Montreal Protocol.
Now a days what you see in Kitchen and vehicles are NOT halon but earlier it used to be Halon.
Dear Abhay - AFFF is the only foam used for fighting class B fire and you will find this foam throughout the world in Refineries and petrochemical. Chemical foam has been obsoleted. Now a days some have strted FFFP and polar solvent foam according to the hazards.

Dear Neeraj
Once again thanks for the explanations and giving latest updates regarding fire fighting...
@Abhay
Thanks for your comments and appreciating your interest in participating this thread and the initiative you took in discussing this topic with your Safety Officer... As rightly pointed out by Mr.Neeraj Chemical Foam is obsolete now and has been replaed by air foam... There are mainly two types of Foam Extinguisher, 1. Mechanical 2. Chemical... AFFF is the agent used in Mechanical Type extinguishers wherein Chemical Foam extinguisher contains Sodium bicarbonate and aluminum sulphate solution... My question was particulary about Chemical Foam... Now you discuss with your Safety Officer, he might be thinking about the Mechanical Foam type and give answer... Come back with your comments Abhay if any...
Halon nowadays been replacing with the Clean Agent or Inert Gas systems...
Thanks to all for valuable participation...
