**Has the use of halon 1211 fire extinguishing agent been prohibited?

It’s not completely prohibited, but it depends on the location where they are installed; halon fire extinguishers are no longer used in places where they aren’t necessary, and those that are already in use will be phased out gradually. According to Section 4.2.6 of the GB50140-2005 Code for Design of Fire Extinguisher Installation in Buildings, halon fire extinguishers should not be installed in places where they are not essential. Examples of non-essential locations are provided in Appendix F of this specification. Halogenated alkane fire extinguishers can be installed in necessary locations.

Notice on Ceasing the Production of Halon Fire Extinguishers in Shanghai [1999] In accordance with the requirements of the Comprehensive Plan for Phasing Out Halons in China’s fire protection industry, and with the approval of the Fire Protection Bureau of the Ministry of Public Security, production and sales of halon fire extinguishers will be halted first in Shanghai. The details are as follows: 1. Starting from January 1, 2000, the production (or conversion to other products) of Halon 1211 fire extinguishers will cease. II. Starting from October 1, 1999, except for the four specialized outlets that sell and repair halon fire extinguishers—Shanghai Global Safety Equipment Factory, Shanghai Xiaoxin Fire Fighting Equipment Repair Department, Shanghai Public Welfare Fire Extinguisher Repair Station, and Shanghai Wuxiao Fire Fighting Equipment Co., Ltd.—all other businesses must cease selling halon fire extinguishers. All manufacturers are required to hand over all the fire extinguishers they produce to these specialized outlets for distribution after October 1. The mandatory retirement period for Halon 1211 fire extinguishers is generally 10 years. In other words, even if there are no mandatory retirement requirements in your area, the fire extinguishers in your facility will have reached their mandatory retirement age by the end of the year. Additionally, some provinces and cities have already established such requirements regarding the retirement of Halon 1211 fire extinguishers; it is recommended that you search on Baidu to find out whether your province or city has any relevant regulations

In June 1997, the Ministry of Construction issued partial revisions to four standards: the \"Code for Fire Protection Design of Buildings\" (CBJ16－87), the \"Code for Fire Protection Design of High-Rise Civil Buildings\" (GB50045—95), the \"Code for Fire Protection Design of Civil Air Defense Projects\" (GBJ98－87), and the \"Code for Design of Fire Extinguisher Installation in Buildings\" (GBJ140—90). These revisions specified the locations where halon-based fire suppression systems could be installed and used, as well as the areas where halon fire extinguishers could be placed. In November 1994, the Ministry of Public Security and the former Environmental Protection Bureau issued the \"Notice on Banning the Further Use of Halon Fire Extinguishers in Unnecessary Locations\" (Public Notice No. 94)

In accordance with the comprehensive phase-out plan for halons in the fire protection industry established by the Ministry of Public Security and the **State Environmental Protection Administration, production of halon 1211 fire extinguishing agents was to be halted by 2005, and the halon 1211 fire extinguishers in use were to be gradually replaced by ABC dry powder fire extinguishers, carbon dioxide fire extinguishers, foam fire extinguishers, and other clean-type fire extinguishing agents.

Notice on Issues Related to the Phasing Out of Halon-Based Fixed Fire Extinguishing Systems and Halon Fire Extinguishers – Public Security Document No. 031 To the fire departments of the public security ministries and bureaus in all provinces, autonomous regions, and municipalities directly under the Central Government: The Ministry of Public Security and the former **Environmental Protection Bureau issued the “Notice on Banning the Further Installation of Halon Fire Extinguishers in Non-Necessary Locations” in November 1994 (Public Security Document No. …). In accordance with this document issued by the Fire Department of the Ministry of Public Security, Halon fire extinguishers must be phased out!

Based on the laws, regulations, norms, and standards provided by the above-mentioned experts, my summary regarding 1211 fire extinguishers is as follows: 1. The production of halon 1211 fire extinguishing agents was halted by 2005； 2. It is prohibited to install halon fire extinguishers in unnecessary locations, as well as to install and use halon-based fixed fire suppression systems. 3. Halon fire extinguishers can still be installed in necessary locations, and halon-based fixed fire suppression systems can continue to be used, but consideration must be given to the deadline for phasing out halon as well as the availability of alternatives to these substances after their elimination. 4. Gradually replace the currently in use Halon 1211 fire extinguishers with ABC dry powder fire extinguishers, carbon dioxide fire extinguishers, foam fire extinguishers, and other clean-fire-extinguishing agent fire extinguishers. Dear friends, may I use the information above to submit it to the company in order to persuade the management to eliminate the 1211 fire extinguishers?

If it is already in use and still within its valid period, there is no need to retire it. Of course, if it is retired, it indicates that your organization truly has a strong awareness of environmental protection. However, I personally recommend transferring 1211 to places such as laboratories or electrical rooms. The fire-extinguishing capabilities of 1211 are excellent, and it is much easier to use than CO2. Moreover, retiring it now also involves considerations related to environmental protection

Guidance Catalogue for Industrial Structure Adjustment (2005 edition). Note: The year in parentheses after each entry indicates the deadline for phasing out 해당 industries; a deadline of 2006 means that these industries should be phased out by the end of 2006, and the same principle applies to the other categories； For entries with an elimination plan, they are eliminated according to that plan ； Entries without a specified phase-out deadline or plan are **explicitly mandated by industrial policy to be phased out or eliminated immediately. (X) Fire fighting: 1. Dichlorodifluorobromomethane fire extinguishing agent (abbreviated as 1211 fire extinguishing agent) (2005); 2. Trifluorobromomethane fire extinguishing agent (abbreviated as 1301 fire extinguishing agent) (2010); 3. Simple-type 1211 fire extinguishers; 4. Portable 1211 fire extinguishers (2005); 5. Carts-mounted 1211 fire extinguishers (2005); 6. Portable chemical foam fire extinguishers; 7. Portable acid-base fire extinguishers

The main component of 1211 fire extinguishing agent is dichlorodifluorobromomethane. It is actually much more effective than carbon dioxide fire extinguishers~ However, bromomethane can cause secondary disasters, such as poisoning of those who operate it, which is why it has been **phased out**!

**The phasing out of 1211 fire extinguishers is mainly due to environmental reasons; they are gradually being replaced by hexafluoropropane fire extinguishers in some areas.

Halon (a transliteration of Halon) is the trade name for what we commonly refer to as 1211 and 1301; it belongs to a class of chemicals known as halogenated hydrocarbons, and is primarily used as a fire extinguishing agent. It achieves fire suppression by disrupting the complex chemical chain reactions of combustion or explosion. The halon fire extinguishing agents widely used in the firefighting industry are ozone-depleting substances. When people use halon fire extinguishers to put out fires or for training, halon gas is naturally released into the atmosphere. Halons contain chlorine and bromine; when exposed to sunlight in the atmosphere, they break down to release chlorine and bromine radicals. These chemically active radicals combine with ozone, removing an oxygen atom from ozone molecules, thereby triggering a destructive chain reaction that damages the ozone layer and reduces its concentration, resulting in ozone holes. Halons have a lifespan of several decades in the atmosphere, and their destructive effect on the ozone layer in the stratosphere will persist for decades or even longer. Therefore, halons have a tremendous destructive effect on the ozone layer. Scientific research has proven that halons are one of the main culprits behind the destruction of the ozone layer.

The phasing out of halon fire extinguishing agents is similar to the phasing out of the refrigerant Freon, as their use is prohibited due to their damage to the atmospheric ozone layer.

The friend upstairs gave great advice: for those that have passed their expiration date, use other fire extinguishers instead； There is no excess; continue using it until it expires, and then replace it with another fire extinguisher.

Sevoflurane fire extinguishers should be able to replace 1211; if not, look for other alternatives. Why must one use something that is explicitly prohibited?

I think I heard it mentioned by the Safety and Environment Department, but it’s still being used; I’m not sure if there’s a ban in place

In November 1994, the Ministry of Public Security and the former **Environmental Protection Bureau issued the \"Notice on Banning the Reinstallation of Halon Fire Extinguishers in Unnecessary Locations\" (Document No. Gong Tong Zi 94)

Fire extinguishers have a certain service life and usage standards.

Primarily, halogenated alkanes are carcinogenic substances; they also possess high chemical stability, posing significant environmental hazards. I study environmental science and am currently working on environmental protection projects related to chemical industries. I’m glad to be able to exchange ideas with everyone here. Additionally, I would like to mention that in terms of water supply safety, there is consideration being given to alternatives to chlorination, as the organic substances present in natural water bodies can produce halogenated hydrocarbons during the chlorination process, which can harm health. Alternatives include ozone and chlorine dioxide

From an environmental protection perspective, it should be replaced； There’s no other choice but to replace them gradually; by following the advice of the security department, a company can survive. It’s sufficient to use higher authorities to pressure the company’s leadership ； Otherwise, safety-standardized enterprises won’t be able to pass

Everyone, I’m no expert in fire prevention and suppression; all I know is that the \"Code for Fire Protection Design of Buildings\" has been updated to GB50016-2006. This post was last edited by fanxh on 2009-4-7 10:58.]
