Talk:NFPA 704

From Wikipedia, the free encyclopedia

There's more than enough info here to satisfy a user using Wikipedia as a reference tool. I'm getting rid of the stub template. JD79 23:42, 12 November 2005 (UTC)

[edit] Examples?

It would be nice if there were a short list of examples. I'm curious as to what each number means in particular outside of just "how dangerous" a substance is. For example I've heard that for flammablility

  • 0. Inflammable
  • 1. Can be ignited (things like wood etc)
  • 2. Easily ignited
  • 3. Likely to ignite (Gasoline)
  • 4. Ignites when exposed to air

But that's just something I heard somewhere.

this advice could end up saving your life: Inflammable does not mean non flammable. From dictionary.com: "inflammable, adj. Easily ignited and capable of burning rapidly; flammable. See Usage Note at flammable." 69.118.241.173 00:25, 26 November 2005 (UTC)

[edit] Radioactive trefoil image

The "radioactive trefoil" image embeded in this article is in SVG format, and that is not fully supported by many browsers. It would e a good idea to replace it with a PNG.

[edit] Ammonium chloride?

It says that Ammonium chloride is in class 2 in Blue/Health, but in Ammonium chloride page it says it's in class 1.

Similarly, it says that sodium chloride is in class 0 but on the NaCl page it's in class 1. 67.185.99.246 23:35, 9 January 2007 (UTC)

[edit] Spelling of chemical names

In the White/Special section, 82.9.59.47 changed from the American spelling, "Cesium," to the British spelling, "Caesium." Since NFPA is a US based organization, I believe US spelling is more appropriate and have accordingly reversed that change. (I see 82.9.59.47 made a similar change for sulfur/sulphur in another article where a regional association is not present, so either spelling should be equally acceptable.)

[edit] OXY special symbol

I saw this OXY symbol in the special area. I saw this in two places: on a truck with oxygen containers, clearly marked, and in a pool shop, which pretty much has oxygen in it. I'm not sure why these were there (i'm not sure if they are flammable or any other thing) but I'm wondering if anybody else saw this. Thanks. FinalHeaven 05:02, 1 July 2006 (UTC)

Oxidizers (such as oxygen) contribute to the combustion of other materials, making them burn with more intensity than they would in a normal atmosphere, and can make some materials burn that would otherwise have difficulty doing so normally. In general, they can make a fire (and fighting a fire) more hazardous.--CheMechanical 19:41, 3 November 2007 (UTC)

[edit] broken box?

Why does the diamond not render correctly in this article? It's actually outside the infobox. -- Mikeblas 02:34, 25 February 2007 (UTC)

Look at the recent history of the article. At 02:22 on 21 February 2007 Flip619 made changes and contributed the following Edit Summary: "made heading fire diamond into an example of an actual chemical; someone please fix the table (or everything about it, really)"
It is pretty clear to me that Flip619 is not skilled in modifying tables, thus the mis-alignment. I lack those skills, too. So please fix it if you can. Pzavon 15:41, 25 February 2007 (UTC)
