Mechanism of function[edit]

How does it work?LorenzoB 05:35, 13 August 2007 (UTC)[reply]

See Gaseous fire suppression, "Inhibiting the chain reaction of the above components". Fireproeng 01:08, 14 August 2007 (UTC)[reply]

According to https://www.orrprotection.com/blog/bid/161598/halon-1301-top-6-most-asked-questions (section "Is Halon Safe?") it does not remove oxygen from the air, so it is probably only harmful if it touches the exterior part of a person* or enters someone via whatever route of administration. I think that dibromotetrafluoroethane displaces oxygen, though I'm not sure.

*Quote from https://pubchem.ncbi.nlm.nih.gov/compound/1_2-dibromotetrafluoroethane#section=Human-Toxicity-Excerpts and https://pubchem.ncbi.nlm.nih.gov/compound/Bromotrifluoromethane#section=Human-Toxicity-Excerpts: "/SIGNS AND SYMPTOMS/ Excessive skin contact with liquid fluorocarbons should be minimized to prevent defatting of skin ... /Fluorocarbons/ -- International Labour Office. Encyclopedia of Occupational Health and Safety. Vols. I&II. Geneva, Switzerland: International Labour Office, 1983., p. 897". If dibromotetrafluoroethane and bromotrifluoromethane are fluorocarbons then they will defat the skin. --Bringback2ndpersonverbs (talk) 20:56, 27 March 2018 (UTC)[reply]

Danger[edit]

In around 1990 I used to work in data centre that had a number of large mainframe computers and the whole computer room was protected by a halon-flooding system. The halon was stored in a number of green pressurised containers IIRC. We were told that the danger was not so much in the halon itself, but in the fact that the the gas was inert and so when used in a fire it filled the room replacing most of the air, leading to possible suffocation for anyone still inside. Hence the need to rapidly evacuate the room should the fire alarm sound, the halon system being triggered automatically. — Preceding unsigned comment added by 86.112.68.219 (talk) 15:11, 13 July 2011 (UTC)[reply]
I was told the Halon itself at the design - lower percentage is NO danger, no suffocation threat directly. However, the rapid evacuation is for setting A tight seal on space. A inrush of fresh air can lower percentage to level that a reflash can occur. Also if a fire is hot enough it might cause Halon to decompose, and decomposition results gases not certainly are not good for humans (some results are close if not the same as Chemical Warfare gases) 02:49, 19 January 2013 (UTC) — Preceding unsigned comment added by Wfoj2 (talk • contribs)

decomposition products[edit]

COBr2 is one of the decomposition products. that's right? decomposes on water. not very toxic.

but.... the other decomposition product then so is... a toxic fluoride. who wants a cyclone of toxic gases?

I see a problem here.

can halon be exchanged with COBr2 or CO2? is it that its a cold non burning liquid? Wikistallion (talk) 17:49, 22 March 2020 (UTC)[reply]

In popular culture[edit]

Should a section on references to halon in popular culture be added? I've just noticed halon is idea in the movie resident evil (2002),but there must be other instances as well. Citizenkrank (talk) 20:13, 17 October 2022 (UTC)[reply]
