Section 380:50-17-6 - Asbestos encapsulation procedures

Asbestos encapsulation procedures are as follows:

(1) Isolate and clean the work area in accordance with Section 380:50-17-4.

(2) Repair damaged and missing areas of existing materials with non-asbestos-containing substitutes. Material must adhere adequately to existing surfaces and provide an adequate base for application of encapsulating agents. Filler material shall be applied in accordance with manufacturer's recommendations.

(3) Remove loose or hanging asbestos-containing materials in accordance with the requirements of Section 380:50-17-5.

(4) Bridging-type encapsulants.

(A) Apply bridging-type encapsulants according to manufacturer's recommendations.

(B) When using a bridging-type encapsulant, use a different color for each successive coat.

(5) Penetrating-type encapsulants.

(A) Apply penetrating-type encapsulant according to manufacturer's recommendations.

(B) Apply penetrating-type encapsulant to penetrate existing sprayed asbestos materials uniformly down to substrate.

(C) During treatment with a penetrating-type encapsulant, the contractor shall remove selected core samples of the asbestos-containing materials to check the depth of penetration.

(6) Apply encapsulants using airless spray equipment.

(7) Cleanup shall be in accordance with the requirements of Section 380:50-17-8.

(8) Encapsulated asbestos-containing materials shall be provided with caution labels printed in letters of sufficient size and contrast as to be readily visible and legible. Each room or area where the conditions requiring such labels exist shall have a minimum of one (1) such label, and such additional labels as may be necessary to ensure ready visibility and legibility. Piping shall have labeling or marking as specified in the project design. The label shall read:

CAUTION:CONTAINS ASBESTOS FIBERS; AVOID CREATING DUST ASBESTOS IS A CANCER AND LUNG DISEASE HAZARD

(9) Encapsulants shall not be applied to asbestos surfaces which have been water damaged, or which are subject to water or physical damage after encapsulation, or which exhibit signs of delamination.

(10) Encapsulants shall not be applied to any asbestos surface unless:

(A) The asbestos surface has first been tested for substrate adhesion and/or encapsulant penetration in locations to be determined by DOL and by a method determined by DOL, and

(B) The encapsulant has been certified by Underwriters Laboratories to be a rated component of the fireproofing system.
