Talk:EPA list of extremely hazardous substances

Proposal
I propose a similar "international list of toxic substances", because a recent news article mentioned it:
 * "Coca is not poison, and it does not harm anyone in Bolivia," she said. "Making it part of our national coat of arms symbolizes the state's commitment to take it off the international list of toxic substances." --Uncle Ed 19:02, 22 March 2007 (UTC)

Cleanliness
I know it's extremely hazardous, but are you sure it can be considered a substance at all? —Preceding unsigned comment added by 201.9.114.88 (talk • contribs)

Red link recovery
Came here as part of link repair (You can help!) to work on the following, then realised this was out of my scientific depth ! Please can you check that the following names are correct and I have undone my edits ok ?


 * List_of_Extremely_Hazardous_Substances → Cobalt,_((2,2'-(1,2-ethanediylbis))
 * List_of_Extremely_Hazardous_Substances → Phenol,_2,2'-thiobis(4-chloro-6-methyl- - fixed
 * List_of_Extremely_Hazardous_Substances → Phosphonothioic_acid,_methyl-,_s-(2-(bis - fixed
 * List_of_Extremely_Hazardous_Substances → Zinc,_dichloro(4,4-dimethyl-5((((methylamino) - fixed

 * 3 items fixed via reference website as shown above - names were truncated. Final item is ambiguous. Welsh 19:00, 21 August 2007 (UTC)

Please put more substances in!
For some reason, I cannot edit this article now, only the discussion page. But I think nitric acid (it's corrosive, as I said earlier) deserves to go on here as well as nitroglycerin and acetone peroxide (possibly the two most unstable substances ever, though I don't know which is more friction sensetive or the similar but different shock sensitive). —Preceding unsigned comment added by 67.81.42.30 (talk) 21:38, 21 November 2007 (UTC)


 * You don't get it: this list is compiled by a government agency some time ago and displayed here. You cannot just add chemicals to this list. Many editors have tried in the past that is why the article is locked. V8rik (talk) 21:45, 21 November 2007 (UTC)


 * There are various lists for various reasons depending on the regulatory agency involved. This is from EMERGENCY PLANNING AND NOTIFICATION (40 CFR part 355)(EPA) - "355.1(a) This part (40 CFR part 355) establishes requirements for a facility to provide information necessary for developing and implementing State and local chemical emergency response plans, and requirements for emergency notification of chemical releases. This part also lists Extremely Hazardous Substances (EHSs) and Threshold Planning Quantities (TPQs) in Appendices A and B, which are used in determining if you are subject to these requirements."  This is the definition of extremely hazardous substance from HAZARDOUS CHEMICAL REPORTING: COMMUNITY RIGHT-TO-KNOW (40 CFR part 370)(EPA) - "Extremely hazardous substance (EHS) means a substance listed in Appendices A and B of 40 CFR part 355."  This is the definition of hazardous chemical from the same document - "370.12(b) The EPA has not issued a list of hazardous chemicals subject to reporting under this part. A substance is a hazardous chemical if it is required to have an MSDS and meets the definition of hazardous chemical under the OSHA regulations found at 29 CFR 1910.1200(c)."  The definition of hazardous chemical in 29 CFR 1910.1200(c) is - "Hazardous chemical means any chemical which is a physical hazard or a health hazard."--Jake1402 (talk) 21:21, 29 July 2009 (UTC)

Asbestos isn't included because? — Preceding unsigned comment added by 121.208.117.237 (talk) 05:53, 25 April 2017 (UTC)

Error
Well the list may be government compiled, but the links are not, thus cyanuric fluoride (CAS number 675-14-9) links to Cyanogen halide which is not the same.

Actually to be honest the list is crap, 'sulfuric acid' and 'Tabun' are in the same list. Trust me, there is a difference. —Preceding unsigned comment added by 87.110.241.125 (talk) 00:52, 11 March 2008 (UTC)

Why is ... on the list?
Why is peracetic acid on the list? Other than because the government said so ("Why did they say so").

Just curious, not only because of what has been left off the list, but its interesting that a chemical that can technically be formed in a person's mouth using stuff the FDA says can be stuck there (vinegar and hydrogen peroxide, apparently k~=.4 at room temp?)

There does exist a need for explanation, especially for compounds like this where the compound's article doesn't indicate specifically why its (especially) toxic... or even what about peracetic acid makes it worthy of a public-right-to-know law? Keeping in mind that everything is eventually toxic at some dose, this doesn't seem especially bad, it breaks down into common natural products easily, without bioaccumulation, probably hurts during incidental exposure (making continued exposure less likely), and has a rather strong odor (making continued exposure less likely)... so what on earth makes it comparable to the majority of everything else on this list?

Well it's on the official list. Apart from that I don't know why it is on. --Rifleman 82 (talk) 03:42, 8 June 2010 (UTC)
 * I clicked it. I think maybe we should add something about the reporting thresholds then!! I can clearly see how having 500 pounds of peracetic acid in the neighborhood might be dangerous, even though storing a gram of it diluted across a liter of water is apparently next to harmless. Thanks for the link; since its a US government document I believe we can just directly import the threshold quantities without any worries about plagiarism, copyright, etc ... right?

Cyanide
Please include cyanide! whiskers75 (talk) 12:29, 26 October 2010 (UTC)
 * Compounds containing cyanide, such as sodium cyanide and potassium cyanide, are on list. -- Ed (Edgar181) 12:46, 26 October 2010 (UTC)

Abrin
Please include Abrin deadlier than Ricin Drlectin (talk) 19:39, 12 June 2011 (UTC)

Both are not in the list. --Rifleman 82 (talk) 22:05, 12 June 2011 (UTC)

Correct substance name?
A couple of weeks ago it became apparent that not all of the substances listed were named correctly in this article. One that I'm suspicious may be part of this list is Cobalt, (2,2'-(1,2-ethanediylbis)); I've been looking through Google to find information on this substance, but every source I look at seems to imply that there's more to the name than just that. I don't suppose the name mentioned here is the correct one? Like my singing? Ha-la-la-la-la-la-LA-LAAA!!! (talk) 09:37, 10 October 2012 (UTC)

Can anybody create a German or Russian page of this topic?

 * I have just tagged the page to globalise it, this means rewriting the article so it can represent a global viewpoint. It this case, we have to combine all 'extremely hazardous chemicals' from other, worldwide organisations, rather than just rely on this single country for this article. DS Crowned (Talk) 11:25, 7 October 2014 (UTC)

Needs globalisation
This article is all about United States' version of extremely hazardous substances, we need more lists from other dangerous goods organisations around the world. DS Crowned (Talk) 11:31, 7 October 2014 (UTC)

"Azidoazide azide"
This is a nonsensical chemical name that appears to be pulled from a satirical article about another chemical where it is referred to as such in the title. The substance in the article (1-diazidocarbamoyl-5-azidotetrazole ) has only been produced in very small experimental quantities. It looks like this is possibly a case of vandalism. — Preceding unsigned comment added by 73.88.213.179 (talk) 22:42, 13 December 2016 (UTC)

Why is Acrolein on the list??
Didn't Nilered make acrolein on one of his videos??? Even though he did emphasize that it is toxic, if a ameture chemist made such a chemical, why is on the list of "extremely hazardous substances"?? I mean, is that basically meaning that it is not extremely hazardous? XXGuyWithAnAxeXx (talk) 21:16, 4 February 2019 (UTC)

Requested move 3 January 2020

 * The following is a closed discussion of a requested move. Please do not modify it. Subsequent comments should be made in a new section on the talk page. Editors desiring to contest the closing decision should consider a move review after discussing it on the closer's talk page. No further edits should be made to this discussion. 

The result of the move request was: consensus to move the page to EPA list of extremely hazardous substances at this time, per the discussion below. Dekimasu よ! 14:50, 22 January 2020 (UTC)

List of extremely hazardous substances → ? – Per WP:GLOBAL. The current title does not reflect the fact that the list is exclusively based on laws and regulations of the United States. I'm not sure what it should be moved to, maybe EPA list of extremely hazardous substances (similar to DEA list of chemicals) or List of extremely hazardous substances (US) (like List of Schedule I drugs (US)). Surachit (talk) 21:33, 3 January 2020 (UTC)
 * Move to or  (or similar) as an improvement of precision (not just as a matter of being U.S.-centric). The list is one particular official list and should be identified as such. It's not really a matter of being specific to the U.S., since these substances are presumably hazardous outside the U.S. as well, but rather it's a matter of being one particular official list. There may also be other substances that most people would consider extremely hazardous that are not in this particular list. It is simply one specific list, and we should identify what list it is. —BarrelProof (talk) 16:15, 4 January 2020 (UTC)
 * Support move to EPA list of extremely hazardous substances. BD2412  T 02:18, 20 January 2020 (UTC)

Addition of Another Compound.
I want this list to be updated. I propose "lead sulphate" To be included in this list. In case the admin is reading this please consider my suggestion!! TheGameGK (talk) 22:28, 22 April 2020 (UTC)

Proposal.
In case, I am making suggestions and amendment to this particular section.. I also want "Dimethyl Cadmium" and "Dimethyl Mercury" to be added. Thank You. Both these compounds are highly carcinogenic. TheGameGK (talk) 22:52, 22 April 2020 (UTC)

Another Addition.
I strongly prefer other members to please refer to this article: https://m.timesofindia.com/city/kozhikode/Ban-on-diclofenac-a-lifeline-for-vultures/articleshow/48767339.cms I think "diclofenac" should also be included. I know it might be a prescribed medication but is lethal to wildlife!! TheGameGK (talk) 23:24, 22 April 2020 (UTC)

Proposal.
I also do think that "anatoxin-a" Should be included in this list.. Also known as very fast death factor!! TheGameGK (talk) 20:03, 31 May 2020 (UTC)

Remove muscimol
Muscimol was listed in the EPA's Extremely Hazardous Substances (EHS) list according to a 1998 publication (source: https://www.ecfr.gov/current/title-40/chapter-I/subchapter-J/part-355). However, they removed it later (source: https://www.govinfo.gov/content/pkg/FR-2006-08-16/pdf/E6-13491.pdf#page=16). --94.255.152.53 (talk) 05:18, 31 May 2024 (UTC)
