| | | Asbestos detection questions? < on 7/7/2003 9:56 PM >
| | | Are there sensors that detect levels of asbestos in the air? If they exist... Where can they be obtained, how much do they cost, are they effective? Also, I go to a university with access to a lot of chemistry labs and I know several chem majors. If I brought them air samples from buildings, could they feasibly run asbestos tests? THanks, peace.

| | | What made asbestos so popular as an insulator was it's temperature resistance, and the fact it's almost completely non-reactive. Means detection is often done by microscopic examination.

| | | I see. The more I read, and the more I talk to people who are involved in the medical school here, the less dangerous short bursts of exposure to even large amounts of asbestos seems. It appears that it is a lifetime of working with volatile forms of the material (spray on insulation, for example) that causes cancer. My habit of barbequeing is probably much more dangerous. Makes me wonder if it's worth trying to don a gas mask every time I wander into a mystery atmosphere. Any thoughts?

| | | There are plenty of cases of developing the cancer with fairly limited exposures. Different people do seem to be more or less sensitive to it. Being a smoker increases your risk dramatically as well. I'd use the mask...

| | | Yes... I wouldn't mind wearing the mask... If I had the right protection... I do have a cartridge type respirator but the cartridges I have don't say any thing about protecting agenst Asbestos... how much to you think the Asbestos cartridges cost ? So.. ExKa|iBuR, what mask do you use... as well as any one eles ? Nemos

| | | Asbestos cartridges dont cost too much relative to others. What you need is either a HEPA or P100 filter. They should run between $5-10 for a pair. Both of those filters will protect from asbestos and other particulates, but these wont protect against chemical/biological stuff, unless you get some kind of combo filter. The combo filters are a bit more expensive, and will wear out sooner as they have a more limited lifespan, and they can expire too. The plain particulate filters are changed when they get dirty and its hard to breathe through them. I just bought a nice new North 7700 silicone half mask with 2 sets of P100 filters. It ran me about 43 dollars. 21 for the mask and like 20 for the cartridges, plus tax. It's really nice and comfortable and pretty easy to breathe through.

| | | well I dunno what my Cartridge's are really good for.. heres the info I got Part No. N7500-3 NIOSH. 1997 protection: Chlorine Dioxide, Chlorine, Hydrogen Chloride, Hydrogen Fluoride, Organic Vapors, Dulfur Dioxide still wraped up..
heres another thoght... now, lets say you go into a place where there is plenty of Asbestos and you wear a mask and the rest of your normale cloths... yah think you safe right ? but hat about when you come back out n take the mask off.... will the Asbestos "cling" onto your clothing, hair n such ? meaning you could still breath it in after ? jest thinking out loud again...

| | | Well, the mask I use I got from my old job. There's new NIOSH standards, but each filter has a different colour. You want the Purple one. That filters out asbestos, and a bunch of other things. The other common (and good one) to have is a yellow one. That filters out organic vapours, such as what would be found in a silo and drain. Better yet, get a yellow/purple one. A yellow one WILL NOT filter asbestos. You can get a good one at most hardware stores for about 20 dollars, or more. As for it clinging - yeah, it probably would. Whenever I UE anywhere, I change into dedicated "UE" clothes which I keep in a plastic bag, and wash separatly. There's always a SLIGHT chance for cross-contaminiation, but not a level which would be harmful. There's always a certain level of asbestos in the air as it is, so chances are, the risk of things clinging to you is very low. -Ex

| | | I would be EXTREMELY carefull with that filter you have from 97. Especially since it is a chemical filter. These have set expiration dates and are no longer effective after that, but more important than that, some of these can actually become toxic themselves after they are expired. Be very carefull and check the expiration dates, as well as the amount of exposure the filters can handle and of what. A chlorine filter is most likely not going to do you any good with asbestos and vice versa. As far as colors go, those vary from brand to brand. This is the filter I use, it's made by North Safety and it covers particulates like asbestos: http://www.sharpesafety.com/catalog/product-display.php3?ID=524 This is the mask I use: http://www.sharpesafety.com/catalog/product-display.php3?ID=523 Do some research on where you are going and what you will be running into. If it's just an old building where there may be some asbestos, the P100 will be fine, but if you are going to some industrial site where there are potentially hazardous chemicals, you might want to look into something else.

1 in 6 500 000, if it's bagged asbestos. My mom used to work in a bulding full of the stuff, and when they shut it down, they handed out information packeages. 1 in 6 500 000. Usually it's sealed in plastic bags. Eben when it's not, it's what's known as a chronic poison. It takes long-term exposure. It's the exposure that kills you. I'd keep a mask, because some of the airborne molds in a lot of buildings.

| | | as i've stated in previous asbestos threads, there are cases of short term exposure causing mesothelioma (including a 12 year old boy exposed only several times over 3 months). I'm not saying it's likely, but it is a possibility, and it's not a thing you want to look back on and say "I guess I should have worn a respirator". It's not like a broken leg or something, it's permanent, well for as long as you survive with it...

Jester is raising a good point - asbestos is completely non-reactive. Once it's in your lungs, it's there for the rest of your life. The cancer is caused by your body's inflamation response over time to the presence of asbestos fibres, since your immune system is trying to get rid of it but can't.

Actually, I've been reading about it quite a bit and it seems that some forms of asbestos do break down in your lungs and disappear, somehow. It's the long fibers that are most persistent. It's possible that the 12 year old boy was put in contact with one of the more dangerous forms of the material... not the typical type that was used in most US (and possibly Canadian) buildings. And who's to say the young lad didn't spend the first two years of his life sniffing clumps of loose insulation to wash down his paint chips, and then forgot to report it to the doctors, knamean?

| | | Well as for asbestos detection, since it's microscopic, I think it is good idea to know where it sits inside a building so at the very least you can avoid disturbing those areas, creating a less risky environment. I'm pretty sure it is usually wrapped around pipes (a certain kind??) and ceiling tiles. Does anyone else know where it is commonly found? I'm speaking of friable asbestos, which can crumble easily and get in the air. I don't think non-friable asbetos would be harmful unless your cutting/breaking stuff, and if you are you deserve it 8P~

| | | It does break down, it just takes a long time. Jester, keep in mind it was a twelve-year old boy. Also, anything's possible, he could have had an allergic-type reaction. Although non-reactive, it does dissolve in some compunds, and does eventually wash out. It's a chronic poison. Saying it will kill you in one dose is wrong. Same as sarin is acute. Saying you need saveral doses is wrong. Got it?

| | | I think the really important thing here is... I'm gonna be fine. I will take a lot of risks, especially when it comes to pitting my own personal abilities against a challenge. But the challenge of not getting cancer from asbestos is not one of the things I want to try...
