Get a professional. Asbestos dust is a real killer, and frankly it's not worth the risk of residual dust - especially if you have young childeren. In Australia the Queensland government even have a "Dob in a neighbour" program if you think that someone is doing DIY asbestos handeling. That's how serious it is.

Still chlorinated, but if handling chemicals is the issue, how about a salt water pool? The alternative I've seen pushed is copper-oxygen system. I can't say how effective it is, but last I checked it is not approved by the EPA for sanitizing water. I've also read that they take more attention and care. Just based on experience having a pool in full ...

My grandfather was a carpenter and when he retired he moved most of his tools into his basement. This included a drill press, bandsaw, and a very heavy full size table saw. It is definitely doable. Drill presses and bandsaws don't generally create as much dust as sanders and routers. You can probably remove most of the dust they'd create with a well placed ...

It's not really that serious in most cases. In tile or siding, it isn't a hazard unless it is broken down, generating dust that you are breathing. Even then, a lot of tile is like 1% asbestos. If you can get it up without breaking it too much, you're basically fine. Pipe insulation that is soft is more of a problem. You can probably do it yourself if it's a ...

Compared to holding a mobile phone against your head, the exposure levels are very low. So, even if non-ionizing radiation is found to be a health concern in the future (current studies show no reason for concern), wifi isn't going to be the primary source of exposure for most people. If you are concerned, locate your router somewhere other than directly ...

There are many DIY air quality test kits available, that might be the best place to start. This one checks for bacteria on HVAC filters and vents. This one from AirLab actually samples the air to test, though it is a bit pricey. You could also call a professional to come in and test the quality of the air in your home, this can be expensive so I would ...

I have my entire woodworking workshop in my basement. Plenty of people have basement workshops. Just get a portable dust collector like this one: Get good filter bags that filter down to at least 5 microns, smaller is better. And a remote controlled air filtration system like this one to hang from the ceiling. Drill presses make very little dust. ...

There is no detectable effect. In double blind studies where people who claim to be sensitive to electric fields have tried to detect whether a wi-fi source is on or off their results have been no better than chance. What does affect their health is their anxiety over possible health effects. This isn't to belittle that as anxiety can cause real health ...

Cement (the active component of concrete) is a base (an alkali) that can be irritating to skin. It is not very strong and should not be a problem on all but sensitive skin, if the exposure is short or intermittent. It could be very irritating to eyes and nasal passages if there is a lot of exposure. Gloves are not a bad idea (e.g., disposable nitrile) but ...

I don't think it is much of an issue with individual materials. In general most of them last a long time, and when they do fail, they simply get replaced. Of course, it can be a problem if the item that is failing cannot easily be replaced. Off the top of my head I think the only issue could be the foundation. Many homes built that long ago did not ...

There are thousands of species of mold known to Science, with different species being found in different parts of the world. There isn't any one "crawlspace" mold or "air duct" mold, it's just whatever spores of whatever species happened to take a foothold there. Which one is more dangerous will depend on the particular species of mold and the sensitivity ...

The home lead testing kits are very accurate if used properly, but only spot check. I buy these same kits in boxes of 50 for home inspections. If you are concerned about widespread lead, you need to have an electronic scan dome by a pro. This type of electronic camera can detect lead in walls, trim, interior or exterior and can cover an entire house in ...

You are correct regarding the dust filters... in fact the "caking" particles can sometimes improve filtration... so the cartridges only need to be replaced when damaged, soiled or when they unacceptably obstruct breathing. As for chemical filters... this depends a great deal on the chemicals being dealt with, as each will have different properties. Each ...

"Asbestos in the ceiling' is rather vague. Are they referring to the ceiling itself? Popcorn texturing? Insulation above the ceiling? As for the danger level of asbestos, it all depends on if it is airborne or not. In its solid state, it's harmless. It's only when it's friable and turns to dust and you inhale it does it become dangerous. Even then, note ...

Varnish is usually a mixture of a drying oil, some resin such as pine tar, and a solvent such as turpentine. The drying oil most likely won't kill you. The most commonly used oil, linseed oil, is actually just non-food-grade flax oil by another name. The Greeks put pine tar in their wine, and it's a tasty treat. The solvent is a little more troublesome. ...

Mold detection and identification can be done in two ways. Visible mold can be collected on a test tape, and air borne spores can be collected with an air sample kit. Either way, samples must be sent to a lab for microscopic inspection and ID. Mold and mold spores can range from common everyday varieties that rarely have negative effects on humans to very ...

Please, please wear gloves! Especially if you are a DIYer, and will be working on a project that involves any more than two pounds of cement. I did not listen to the warning, and worked with the wet cement without gloves. We were filling the bottom of a pond that had cracked, and spent about 5 hours across two days working. I didn't notice anything at all ...

As you can see from the other answers, there is a range of opinions. I have observed that some people handle concrete bare-handed without trouble, while others' skin reacts very badly. For example, my neighbor got sores very fast with exposure to concrete while setting fence posts. And I've heard reports that these types of sores heal very slowly. If you ...

It boils down to maintenance. There are tons of houses in northeast that 300+ old. Some brick and some wooden. So if the house was properly kept then I don't think it has a pre determined lifespan. However, specific building materials do have known time in service before they would require repair. For example bricks might need to e repointed every 50 years ...

Yes you can paint them with high heat BBQ grill paint. You can find this paint at any hardware store, walmart or lowes etc. It is rated for 1400 degrees normally. Be aware, however, that the surface in contact with your pans will wear off fairly quickly. I personally would paint the grates, then burnish the paint off where it makes contact with the pans so ...

Given the direct flame exposure, and that the flames are actually quite a bit hotter than BBQ paint is rated for (1950C for natural gas, 2392C for propane) I'd suggest sticking to clean, coat with vegetable oil (wipe on a thin layer) and bake. This makes a pretty good finish, and does not involve anything that's not going to happen in normal food preparation ...

Yes it will be unhealthy... if you dont have any ventilation 1- MLA / MLZ external grille 2- Filters (hepa/etc)(not required in your situation) 3- a reliable higher quilaity not el-cheapo air fan 4- sensors (not needed here) 5- heater/cooler (not needed here) 6- Grilles 9 - AVM Backflow preventer (important) 10 - AS shutter 7,8 - Switches (not ...

The answer is no, normal sheets(no matter the thread count) will not keep dust mites and pollen from entering your mattress and box spring. It is possible a mattress can increase it's weight due to these two processes. So I will assume this question to mean HOW can you cover the mattress to prevent....... Well, for one I never take the mattress out of ...

Non PT wood will be fine. I would build a 32x22" frame out of 2x4's but I would put a 3/4" square notch around the inside diameter of the frame and set the filter into that notch. That will give you a nice seal for the filter but prevent it from falling through. If necessary, add one or two cross braces across the inside of the frame cut to the depth of ...

The magic words you want are "RRP", the EPA Renovation, Repair and Painting rules. For a simple residential demolition that's all you need. For details see http://www2.epa.gov/lead/renovation-repair-and-painting-program Homeowners can take the RRP certification course (I did), but in most cases you'll want to ask the contractor for their RRP certification ...

If mold is an issue in your house I'm not sure a furnace filter is really going to help, even a HEPA filter as all it will do is filter the air passing through the filter; it won't do anything to prevent the mold spores from entering the air where they are growing. Generally the best solution to mold issues is to solve the moisture issue. If you have any ...

About any reasonably sized HEPA filter unit should do the job for you. There's huge price variations in the things, so looking for a unit w a decent fan motor, open cell foam pre-filter, and a low price is worthwhile. If you're do-it-yourself capable, they're not all that hard to make using a store-bought HEPA filter replacement filter, like this or similar, ...

I would venture a guess that @Tester101's suspicion about your floaties coming from your glass (unrinsed soap, dust, etc.) may be heading down the right path. I would try rinsing a glass, scrubbing it with a new sponge or clean washcloth, wiping it dry with a clean towel (not paper towel, as this may leave pieces of paper behind), and then refilling it. ...

You'd be better off with a box fan as it has a large, square area that will support your filter media properly. It will need to be powerful enough to develop airflow despite the next addition. Not sure if you can find it, but we have here available electrostatic filter media by the roll. Cut several pieces large enough to cover the inlet side of the box ...

You may notice a rotten egg odor from the water from time to time if the sulfur content is high enough. Bacteria in the water convert sulfur compounds into hydrogen sulfide which reacts with the copper to form a coating of copper sulfide. There are no set limits on how much sulfur can be in the water. It's naturally occurring and not considered to be a ...
