How To Identify Asbestos Corrugated Sheets
What are the dangers of removing an asbestos garage roof.
How to identify asbestos corrugated sheets. For example sheets of asbestos were used to make up walls and slats of asbestos were created to serve as roof tiles. Cover exposed skin wear a hat gloves disposable overalls with a hood safety goggles glasses and a dust mask with built in respirator. If you do some research over the corrugated asbestos cement sheets you will find that cacs is classified as the low risk asbestos containing materials you should know that the asbestos fibres in corrugated asbestos cement sheets bind strongly to the base material matrix that is why corrugated asbestos cement cannot release any sort of asbestos fibres in normal situations. Usually in code form the name of the manufacturer the date of manufacture the shift and possibly the machine it was made on will be provided here.
Each mold has a different location that may be stamped with manufacturer s information. The manufacturers mark on profiled sheets is indented into the overlap of the side lap roll. Although the sheets should carry the indent on the overlap roll this did not always happen and even if there is an imprint this may simply be too difficult to read. Don t eat drink or smoke in spaces containing asbestos.
Identification of asbestos in profiled sheets is not a great deal easier either. Corrugated cement panels were used for a short period of time as they break quite easily. Their width can range from 12 to 48 inches and are very simple to identify since asbestos fibers can be seen on the grained sections of the material. While an expert lab test using polarized light microscopy may be needed to identify the specific type of asbestos fiber or to identify the presence of asbestos in air or dust samples many asbestos containing building products not only are obvious and easy to recognize but since there were not other look alike products that were not asbestos a visual identification of this material can be virtually a certainty in many cases.
Asbestos was molded into many different shapes and sizes to fill different needs. Over time asbestos sheets may have been replaced with asbestos free alternatives but if they are particularly old and look weathered they are likely to contain asbestos cement.
