Homeowners and employees may inhale to dangerous levels of silica dust when cutting, drilling, grinding, or otherwise disturbing materials that contain silica. These materials and tasks are common on construction jobs. Breathing that dust can lead to serious, often fatal illnesses. Know to understand the risk factors with silica.
There are ways contractors can reduce the dust and reduce the hazard. Selecting appropriate controls, and creating a job-specific plan to eliminate or reduce silica hazards is essential for any tile removal or wood floor removal.
How to Get Rid of Mold - Common Causes and Cleaning Techniques – Entrust is to an Expert
Think you've got mold? Mold sampling is the first thing to do. There are several ways to collect and analyze mold samples. You can take a surface sample, air sample or use a do-it-yourself kit.
The most basic type of mold sampling is surface sampling. If you've got visible mold in your house, you can take a sample of it, and analyze it to see if it is toxic or not.
There are a number of techniques for taking samples. One method is to use clear tape. Stick the tape to the surface, peel it off, and drop the tape into a plastic bag with the mold sample stuck to it. This sample can then be analyzed.
You can also swab the area for samples. You can take a regular Q-tip and swab the area 3-4 times, then drop the samples into a bag for further inspection.
Air sampling is the best way to check your mold problem. The results will tell you if you've got airborne mold spores already floating around your house, wreaking havoc on everybody's lungs.
The inspector uses a pump and spore trap. The pump sucks up air and holds it in the spore trap where it can be analyzed. It pumps not only air, but also bits of dust and insects which can reveal more accurately the amount of spores in the air.
This is the most reliable way to check for mold problems because it looks for the spores themselves. The inspector takes samples from various parts of the house, as well as inside walls and under floors. Often, mold infestations aren't visible to the naked eye.
At-Home Sampling Kits
You can buy at-home mold sampling kits to use yourself. These are easy and give quick results. The only downside is that they don't do as thorough a job as a professional mold inspector. There is some margin for errors.
Mold sampling is the first step in ridding your home of mold. If you think you have a problem, check it out and clean it up immediately.
Prevent Mold and Mildew
Mold & Moisture
The crawl space is the number one source for potential moisture entering your home. The moisture may be equal to gallons of water but in vapor form and not even visible. A seal tight liner kit will instantly stop the moisture in the crawl space from entering home as well as eliminating radon gas, musty odors, mildew and mold.
"The U.S. EPA states: "Molds are usually not a problem unless mold spores land on a wet or damp spot and begin growing. Molds produce allergens, irritants and potentially toxic substances. The key to mold control is moisture control. The mold will not grow if moisture is not present (source: EPA " A Brief Guide to Mold, Mildew and Your Home," publication #402-K-02-003)."
Eliminate the Existing Mold
To eliminate and prevent future mold growth, spray the affected areas with a mold killing and growth preventing spray, there are good products for purchase at your local building supply house.
My Take on the Problems with Bleach
The Myth Of Using Bleach To Kill Mold! Mold has a root system that actually grows into the surfaces of wood, drywall, concrete, etc..., like tree roots grow into the soil. The roots are not killed by bleach alone because the bleach does not penetrate the surface of porous materials. The bleach chemical portion sits on the surface until gassing off, killing only the mold on the surface leaving the roots intact, while the water portion of the bleach soaks into the material giving the mold roots a food source to start growing again. Think of it this way, if you were to cut a tree, plant, grass, or anything that has roots down and you water the area, you will see what you cut start to grow again. This is because the roots were not killed. The other problem with using bleach for an extended period is that if sprayed on wood and other building materials it actually starts to break down the products.
STOPPING MOLD AT THE ROOTS IS THE ONLY WAY!!!
Chlorine Bleach is NOT a registered EPA Mold Killing product!
If you think that we're just knocking bleach. Don't take our word for it! Go to http://epa.gov/mold/moldcourse/index.html and read what the EPA has to say about using bleach to kill mold. The EPA says that "The use of bleach is not recommended as a routine practice during mold clean-up" http://iaq.custhelp.com question #7.
Now you might ask: How do I kill mold if not with bleach?
Answer: Use an EPA approved and registered fungicide to kill the mold at its roots.
