NFPA

I think the NFPA symbol is wrong. If I'm not mistaken it should be 3 health, 1 flammability and 2 reactivity. It's not very nice stuff to deal with.

Au contraire, relative to other chlorocarbons and most organics, CH2Cl2 is remarkably benign. It does scare alarmists who are unfamiliar with chemistry. I confirmed that the NFPA listing is current: Health Hazard of 2 and ZERO for fire and reactivity. Great stuff compared to the seriously dangerous materials with less threatening names - say, phthalates.--Smokefoot (talk) 22:36, 17 July 2008 (UTC)[reply]

Unless I am mistaking, in the last revision of NFPA coding, it is 2 for toxicity 1 for fire and 0 for reactivity. —Preceding unsigned comment added by Process engineer france (talk • contribs) 14:45, 16 March 2009 (UTC)[reply]

Flash Point

you should list flash point for all chemicals

Actually DCM is a non flammable liquid thus I understand it does not have a flash point. Maybe we could put "Not Flammable" rather than "none" in the infobox? Berserker79 08:27, 12 December 2005 (UTC)[reply]

is it dangerous

i deal with dichloromethane at work and also have a friend who is pregenant and has come in contact with it, what health risks does it pose for herand is it safe to use.

__Please read the MSDS sheet for water (H₂O and dicloromethane)__

Is this vandalism?

What is the meaning of this line? Does it belong in this article? If so, please rewrite in English.

"Dichloromethane is quite often used as a farming tool in Eastern and Central America as a gene adaptation tool."

Small Dichloromethane Spill

Hello,

I realize this is a talk section, but I am concerned about a small spill at my workplace. I purchased a toy drinking bird which contains this chemical (http://www.thinkgeek.com/geektoys/science/981b/), which was knocked over by a coworker, broken and spilled onto my desk. I cleaned up the area with some water and white board cleaner, and washed my hands thoroughly with soap. I just want to know if, based on the amount seen in the picture, if there is any concern for inhilation or prolonged exposure. —Preceding unsigned comment added by 207.45.240.18 (talk) 20:21, 30 July 2008 (UTC)[reply]

Wikipedia is not an appropriate place to seek advice for health and safety matters such as this. See Category:Wikipedia disclaimers.

If you are worried, the best thing to do is consult any information that came with the product. If that doesn't help, or if there isn't any information available, you could ring the manufacturer. MSDSs for dichloromethane are available online - here's one. That may give some indication of likely problems.

If you're concerned about your health, see a doctor.

NFPA rating?

Depending on where you look, you'll find conflicting NFPA ratings.

Health: 3, Fire: 1, Reactivity: 0 [1]
Health: 2, Fire: 1, Reactivity: 0 [2]
Health: 2, Fire: 0, Reactivity: 0 (current article)

Can someone straighten this out, once and for all? Fuzzform (talk) 21:53, 11 November 2008 (UTC)[reply]

Do NFPA ratings actually come from the NFPA, or are they made up by the manufacturers? (I have no idea.) I suspect the later because I often see inconsistencies between different manufacturers and different MSDSs. --Itub (talk) 07:11, 12 November 2008 (UTC)[reply]

NFPA rating are coming from NFPA. It is responsability of the manufacturers to report it correctly and update it on their MSDSs. —Preceding unsigned comment added by Process engineer france (talk • contribs) 14:48, 16 March 2009 (UTC)[reply]

Useful as Plastic cement

Should be mentioned as a cement solvent for polycarbonate plastic though it must be carefully handled.
