1. Containment. Collect debris removed during cleaning and take precautions to ensure that
debris is not otherwise dispersed outside ACS during cleaning process. After ACS cleaning,
clean any areas that could be affected by cleaning as clean as their condition prior to
commencement of cleaning operations.
2. Particulate Collection: Where Particulate Collection Equipment is exhausting inside building,
use HEPA filtration with 99.97% collection efficiency for 0.3 micron size particles (see EPA's
Building Air Quality). When Particulate Collection Equipment is exhausting outside
building, precautions shall be taken to ensure that exhausted air does not re-enter the building
or cause any damage by accumulation of debris on the adjacent property.

dispose of same. Liquid waste must not be disposed of down any facility drain, be it floor
drain, to the sanitary sewer, or through kitchen grease traps, without written prior approval
from AHJ and Owner’s authorized representative.

contractors shall be able to certify equipment effectiveness of 99.97% collection efficiency for
0.3 micron size particles through DOP test results, from an independent testing agency, for
any collection devices intended for use on a particular job. Where contact vacuuming is

top, bottom, and sides of rectangular duct and the entire circumference of round and
oval duct by creating the least number of access openings possible. The agitation
equipment must be capable of thoroughly cleaning up to 50 lineal feet of ductwork in
each direction per access opening. Owner’s representative must approve any
exceptions. High power/ volume vacuum alone is not an acceptable method of
agitation.
6. Coating Equipment for Application of Insulation Coating Material in Fiberglass Lined
Ductwork and Components: Coating material for fiberglass lined ductwork must be applied
in the ductwork by creating the least number of access openings possible. The coating
application equipment must be capable of thoroughly coating up to 50 linear feet of ductwork
in each direction per access opening. Owner’s representative must approve any exceptions. In
no case shall an encapsulant, coating, or adhesive be applied prior to or in lieu of source
removal mechanical cleaning, as required in this section, 3.3.
