  • Patent number: 6578439
    Abstract: A sheet vinyl flooring asbestos sampling method includes taking a sample of sheet vinyl flooring without dispensing airborne asbestos fibers. The process includes selecting and cleaning a floor sampling site for attaching a floor sampling template to guide the cutting of the flooring and to limit the liberation of asbestos fibers to the ambient air. A sampling container has an opening thereinto with a flat cutting surface adjacent the opening and a cap to fit over the opening so that the sample may be removed by pushing the cutting edge into the vinyl flooring to cut loose a sample which is pushed into the opening of the container. A cap is then placed over the opening of the container and the sampling container and sample is placed within a storage bag for delivery to a testing lab. The process also includes covering the sampling site with a seal having identification material thereon and also the placing of identification information in the storage bag.
