Which factor is NOT included in the EPA’s criteria for encapsulation sealants?

Color variety is not included in the EPA’s criteria for encapsulation sealants because the effectiveness and safety of encapsulation materials focus on performance qualities rather than aesthetic factors. The primary criteria established by the EPA emphasize how well the sealant adheres to the asbestos-containing material and its ability to prevent fibers from being released into the air. This includes evaluation of adhesive/cohesive strength, flame spread characteristics, and the potential toxic gas release during combustion. While color might be a consideration for aesthetic reasons, it does not play a role in assessing the functional integrity or safety of an encapsulation sealant in preventing asbestos exposure.
