can it be used to remove warts?

This is my first, so Feel free to correct the formating and link anything. My dad is using this stuff (coming out of a dust-off can) to frezze a wart (to remove it). Do you think it is wize to add this idea to the article? Sir Intellegent 02:43, 11 September 2006 (UTC)

[in reply to Sir Intellegent] I just tried this myself a few days ago. Stupid idea. Since that day (about a week ago) I have been having really bad abdominal cramps/gas. of course it could be something I ate, and kept eating. I tried to find out who added that bit about abdominal cramps to the article, because it isn't in the medical literature, but it was added by some unknown IP address. Maybe he did the same thing... I moved the reference up before that addition. I don't think I breathed in much, but maybe I did, or it was through skin contact. Also, the bittering agent stuck to my skin and fingers, and got onto my lips/face and made my food taste bitter- it can only be cleaned off with alcohol. Anyhow, I don't think the liquid gets cold enough to do the trick - liquid nitrogen (what they use at the doctor's) is colder - this just gets cold because it evaporates quickly. Be smart: Difluoroethane has medical side effects, whereas liquid nitrogen does not. 98.148.192.41 (talk) 06:35, 20 February 2011 (UTC)rogerthepan

No but duck tape sounds safer. —Preceding unsigned comment added by 72.46.196.154 (talk) 00:26, 3 October 2008 (UTC)

Removed data

Moved here because WP is not an MSDS. --Rifleman 82 (talk) 11:35, 17 November 2007 (UTC)

Physical information

• Vapor pressure: 4020 mmHg/5360 hPa @ 21.1 °C
• Vapor density (air=1): 2.28 @ 25 °C
• Density: 2.7014 g/L @ 25 °C
• Water solubility: 0.54% @ 0 °C
• Viscosity: 0.00887 cP @ 25 °C

Safety

• Major health hazards: central nervous system depressant.
• Major physical hazards: Flammable gas. May cause flash fire.
• When burned in air, decomposes into hydrogen fluoride and carbon monoxide, both of which are dangerous:

2 C₂H₄F₂ + 3 O₂ → 4 CO + 4 HF + 2 H₂O

• Some retail stores are no longer selling this product to people under the age of 21

Effects

Difluroethane droplets boiling away on a sheet of brushed aluminum, where they were sprayed to remove dust.

• Inhalation:
  • Short term: symptoms of drunkenness, suffocation
  • Long term: brain damage
• Skin contact:
  • Short term: frostbite
  • Long term: no data
• Eye contact:
  • Short term: irritation, blurred vision
  • Long term: blindness
• Ingestion:
  • Short term: frostbite
  • long term: brain damage

Why is this being phased out as a refrigerant

The article indicates that difluoroethane is being phased out as a refrigerant. It would be helpful to know why it is being phased out and what it is being replaced with. Also, is it being phased for "compressed air" applications? —Preceding unsigned comment added by Tom vail (talk • contribs) 00:43, 9 April 2008 (UTC)

Very good Article

If you want insert a very good info, insert the GWP value = 140 Is very important about the Ecologicaly Value —Preceding unsigned comment added by 87.28.86.193 (talk) 15:54, 10 September 2008 (UTC)

what happens to it when it gets dissolved in water?

I tried bubbling the gas in a cup of water - it tasted awful. (No, this was not an attempt to abuse inhalants). —Preceding unsigned comment added by 150.135.92.21 (talk) 09:48, 9 November 2008 (UTC)

If the taste stayed in your mouth for awhile, you are tasting the chemical itself. The taste is used as a deterrent against people trying to abuse it and I would assume also doing that. Sticking random chemicals into water (or anything) and drinking it is a sure resipe for disaster. Don't do it. Also, to the wart guy above, no, stupid idea. People, please don't use products for a purpose other than their intended use. If it really was meant to do what you are thinking of doing with it, they would sell it to do that. In summary: messing with chemicals = BAD IDEA. – Andrew Hampe ^Talk 01:46, 20 July 2009 (UTC)

LFL limit

The lower flammability limit (LFL) stated doesn't appear to match the reference given. The value given in IRIS is 37,000ppm. The Material Safety Data Sheet (MSDS) from DuPont, as well as the MSDS from 3M shows the LEL (synonymous with LFL, see Flammability limit), as 3.9% (39,000ppm). --GriffChE (talk) 12:52, 22 September 2009 (UTC)

"152a" listed at Redirects for discussion

Similarity with Propane?

As stated in the article, this chemical (gas) is known in the Air Conditioning industry as R152a; also being used for canister "Air Duster" as well as being sold in canister form as a cheap top-up for automotive R134a A/C systems. People seem to refer to it as being "basically propane camping gas" (this is how I got here). Please can someone consider adding a section outlining the similarity (or not) between Difluoroethane and Propane, or to dispel potential inaccuracy in this statement. Thanks. — Preceding unsigned comment added by 86.156.183.247 (talk) 19:13, 16 December 2019 (UTC)
