The application of an Encapsulating Material to Lead Based Paint to provide a barrier between the Lead Based Paint and the environment.

A rigid durable barrier mechanically attached to building Component, with all edges and seams sealed with caulk or other sealant.

Spiny ornamentation of a conidium.

Are coatings or rigid materials adhesively applied to Lead Based Painted surfaces in the Encapsulation process.

Treatment of PACM with a material that surrounds or embeds asbestos fibers in an adhesive or cementitious matrix to inhibit the release of fibers. The encapsulant creates a membrane over the surface of the material (bridging encapsulant), or penetrates the material or binds its components together (penetrating encapsulant).

An airtight, impermeable, permanent barrier around PACM to prevent the release of asbestos fibers into the air.

Interior component of a bacterial cell that may function as a toxin when the cell is lysed.

Medium that encourages the selective growth of an organism that may not be available in high concentrations.
