Encapsulant (sealant) or encapsulating agent. "Encapsulant (sealant) or encapsulating agent" shall mean pigmented (non-transparent) liquid material which can be applied to asbestos-containing material or the bare surfaces exposed after an abatement which temporarily controls the possible release of asbestos fibers from the material or surface either by creating a membrane over the surface (bridging encapsulant) or by penetrating into the material and binding its components together (penetrating encapsulant).
Encapsulation. "Encapsulation" shall mean the coating or spraying of asbestos-containing material or the bare surfaces exposed after an abatement with a pigmented (non-transparent) sealant.
Enclosure. "Enclosure" shall mean the construction of airtight walls and ceilings between the ACM and the facility environment, or around surfaces coated with ACM, or any other appropriate procedure as determined by the Department which prevents the release of asbestos fibers.
