Asbestos Abatement >> How To Abate & Remove Asbestos & Lead

Testing Uses and Occupational Exposure Asbestos is ubiquitous in the environment. More than 40% of the land area of the United States is composed of minerals which may contain asbestos. Fortunately, the actual How To Abate & Remove Asbestos & Lead formation of great amounts of asbestos is relatively rare. 

Nonetheless, there are locations in which environmental exposure can  be severe such as in How To Abate & Remove Asbestos & Lead the Serpentine Hills of California. There are thousands of uses for asbestos in industry and the home. Asbestos abatement workers are the most current segment of the Â population to have occupational exposure to great amounts of asbestos. 

If the material is undisturbed, there is no exposure. Exposure occurs when the asbestos-containing material is abraded or otherwise disturbed during How To Abate & Remove Asbestos & Lead maintenance operations or some other activity. Approximately 95% of the asbestos in place in the United States is chrysotile. Amosite and crocidolite make up nearly all the difference. 

Tremolite and anthophyllite make up a very small percentage. Tremolite is found in extremely small amounts in certain chrysotile deposits. Actinolite exposure is probably greatest from environmental sources, but has been How To Abate & Remove Asbestos & Lead identified in vermiculite containing, sprayed-on insulating materials which may have been certified as asbestos-free. 

Physical and Chemical Properties The nominal chemical compositions for the asbestos minerals were given in Section 1. Compared to How To Abate & Remove Asbestos & Lead cleavage fragments of the same minerals, asbestiform fibers possess a high tensile strength along the fiber axis. They are chemically inert, non-combustible, and heat resistant. 


Except for chrysotile, they are insoluble in Hydrochloric acid (HCl). Chrysotile is slightly soluble in HCl. Asbestos has high electrical resistance and good sound absorbing characteristics. It can be woven into How To Abate & Remove Asbestos & Lead cables, fabrics or other textiles, or matted into papers, felts, and mats. 

Toxicology (This Section is for Information Only and Should Not Be Taken as OSHA Policy) Possible physiologic results of respiratory How To Abate & Remove Asbestos & Lead exposure to asbestos are mesothelioma of the pleura or peritoneum, interstitial fibrosis, asbestosis, pneumoconiosis, or respiratory cancer. 

The possible consequences of asbestos exposure are detailed in the NIOSH Criteria Document or in the OSHA Asbestos Standards 29 CFR 1910.1001 and 29 CFR 1926.1101 and 29 CFR 1915.1001. 2. How To Abate & Remove Asbestos & Lead Sampling Procedure 2.1. Equipment for sampling (a) Tube or cork borer sampling device (b) Knife (c) 20 mL scintillation vial or similar vial.

Sealing encapsulant 2.2. Safety Precautions Asbestos is a known carcinogen. Take care when sampling. While in an asbestos-containing atmosphere, a properly selected and fit-tested respirator should be worn. Take samples in a manner to cause the least amount of dust. Follow these general How To Abate & Remove Asbestos & Lead guidelines: (a) Do not make unnecessary dust. (b) 

Take only a small amount (1 to 2 g). (c) Tightly close the sample container. (d) Use encapsulant to seal the spot where the sample was taken, if necessary. 2.3. Sampling Procedure. Samples of any suspect How To Abate & Remove Asbestos & Lead material should be taken from an inconspicuous place. 

Where the material is to remain, seal the sampling wound with an encapsulant to eliminate the potential for exposure from the sample site. Microscopy requires only a few milligrams of How To Abate & Remove Asbestos & Lead material. The amount that will fill a 20 mL scintillation vial is more than adequate. Be sure to collect samples from all layers and phases of material. 

If possible, make separate samples of each different phase of the material. This will aid in determining the actual hazard. DO NOT USE ENVELOPES, PLASTIC OR PAPER BAGS OF ANY KIND TO COLLECT How To Abate & Remove Asbestos & Lead SAMPLES. The use of plastic bags presents a contamination hazard to laboratory personnel and to other samples. 

When these containers are opened, a bellows effect blows fibers out of the container onto everything, including the person opening the container. If a cork-borer type sampler is available, push the tube through the material all the way, so that all layers of How To Abate & Remove Asbestos & Lead material are sampled. Some samplers are intended to be disposable. 

These should be capped and sent to the laboratory. If a non-disposable cork borer is used, empty the contents into a scintillation vial and send to the laboratory. Vigorously and completely clean the cork borer between How To Abate & Remove Asbestos & Lead samples. 2.4 Shipment Samples packed in glass vials must not touch or they might break in shipment. 

Seal the samples with a sample seal over the end to guard against tampering and to identify the sample. (b) Package the bulk How To Abate & Remove Asbestos & Lead samples in separate packages from the air samples. They may cross-contaminate each other and will invalidate the results of the air samples. (c) Include identifying paperwork with the samples, but not in contact with the suspected asbestos. 

To maintain sample accountability, ship the samples by certified mail, overnight express, or hand carry them to the laboratory. Analysis The analysis of asbestos samples can be divided into two major parts:  How To Abate & Remove Asbestos & Lead sample preparation and microscopy. 

Because of the different asbestos uses that may be encountered by the How To Abate & Remove Asbestos & Lead  analyst, each sample may need different preparation steps. The choices are outlined below. There are several different tests that are performed to  identify the asbestos species and determine the percentage. They will be explained below. 

Safety (a) Do not create unnecessary dust. Handle the samples in HEPA-filter equipped hoods. If How To Abate & Remove Asbestos & Lead samples are received in bags, envelopes or other inappropriate container, open them only in a hood having a face velocity at or greater than 100 fpm. Transfer a small amount to a scintillation vial and only handle the smaller amount. 

Open samples in a hood, never in the open lab area. (c) Index of refraction oils can be toxic. Take care not to get this material on the skin. Wash How To Abate & Remove Asbestos & Lead immediately with soap and water if this happens. (d) Samples that have been heated in the muffle furnace or the drying oven may be hot. Handle them with tongs until they are cool enough to handle. 

Some of the solvents used, such as THF (tetrahydrofuran), are toxic and should only be handled in an appropriate fume hood and according to How To Abate & Remove Asbestos & Lead instructions given in the Material Safety Data Sheet (MSDS). 3.2. Equipment (a) Phase contrast microscope with 10x, 16x and 40x objectives, 10x wide-field eyepieces, G-22 Walton-Beckett graticule.

Whipple disk, polarizer, analyzer and first order red or gypsum plate, 100 Watt illuminator, rotating position condenser with oversize phase rings, central stop dispersion objective, Kohler How To Abate & Remove Asbestos & Lead illumination and a rotating mechanical stage. 

Stereo microscope with reflected light illumination, transmitted light illumination, polarizer, analyzer and first order red or gypsum plate, and rotating stage. (c) Negative pressure hood for the stereo microscope (d) Muffle furnace capable of 600 deg.C (e) Drying oven capable of 50 -- 150 deg.C (f) Aluminum specimen pans (g) Tongs for handling How To Abate & Remove Asbestos & Lead samples in the furnace (h) High dispersion index of refraction oils (Special for dispersion staining.)
