ABSTRACT:
An anchor is formed in a wall or ceiling composed of friable asbestos containing material by placing a plate member having a seal member around its peripheral edge against the wall or ceiling and then driving a fastener through the plate member and into the wall or ceiling. The plate member is of a size to permanently contain between the plate member and the ceiling any friable asbestos containing material which is dislodged by the fastener. Preferably, the seal, which comprises a sealing strip with an adhesive coating, or a sealing adhesive, temporarily secures the plate member to the wall while the fastener is being driven through the plate member to assure that the plate remains in place; however, it is the fastener which permanently secures the plate member to the wall or ceiling.
