§ 1-103 Encapsulation Procedures.
RCNY § 1-103
All sections of these rules must be followed in conjunction with this section except 15 RCNY § 1-102(e), § 1-104, § 1-105, § 1-107 through § 1-111, § 1-112(c), (d), (e), (g), and (h). Encapsulation procedures must be conducted with the full containment of the work area (see 15 RCNY § 1-81) or the tent procedure (see 15 RCNY § 1-106) as follows: (a) All material used for repair or encapsulation of asbestos-containing material shall have a flame spread rating, fireproofing, and smoke characteristics similar to the material being encapsulated. The encapsulate shall not alter the insulating characteristics of the material subject to encapsulation, and shall comply with current fire proofing standards and the encapsulate shall not add excess weight to the material increasing the potential that the material may lose cohesion or adhesion.
(b)Loose or hanging asbestos-containing materials shall be removed in accordance with the requirements of 15 RCNY § 1-102 and § 1-111.
(c)Only pigmented (non-transparent) encapsulants shown to be ratable as acceptable or marginally acceptable on the basis of Battelle Columbus Laboratory test procedures and rating requirements developed under the 1978 USEPA contract shall be used for encapsulation.
(d)The encapsulant solvent or vehicle must not contain a volatile substance.
(e)Latex Paint with solids content greater than 15 percent may be used as an encapsulant only as follows: (1) as a lockdown sealant for coating all non-metallic surfaces, or (2) for sealing of cementitious ACM.
(f)Encapsulants shall be field tested prior to use by applying each to a small area to determine suitability of the material to be encapsulated.
(1)Testing is to occur only after the isolation barriers are in place.
(2)Testing shall be by the USEPA method specified in the appendix of "Guidelines for the Use of Encapsulants on Asbestos-Containing Materials" (June, 1981) or ASTM Standard Test Method E 736-80. The encapsulated materials shall achieve a cohesive/adhesive strength of 100 lb/ft perpendicular to the surface.
(g)Application of bridging encapsulants over ACM shall provide the manufacturer's specified number of inches or minimum dry film thickness.
(h)A different color for each coat of encapsulant (per manufacturer's specifications) shall be used.
(i)Penetrating encapsulants shall be applied to penetrate existing asbestos-containing materials to the substrate. During treatment with a penetrating encapsulant, selected random core samples of the asbestos-containing materials shall be removed to check the depth of penetration. The resulting space shall be treated as outlined (in subdivision (a)) above and re-encapsulated.
(j)Encapsulants shall be applied using airless spray equipment.
(k)Encapsulated asbestos-containing materials shall be identified (e.g. using labels, signs or color coding) in order to warn building maintenance personnel in the event encapsulated materials must be disturbed.
(l)The following maintenance procedures are required, except when the encapsulated material is on utility lines located in the street: (1) A periodic inspection and maintenance program, consisting of an inspection at least annually to check for damage to all encapsulated surfaces. Recoating and repairs are to be performed according to procedures in this section.
(3)When conditions change and encapsulation is no longer an appropriate method, additional abatement methods should be conducted. (Amended City Record 12/7/2018, eff. 1/6/2019; amended City Record 4/28/2022, eff. 5/28/2022)
