Open ducting shall be protected from construction dust and debris in a

be cleaned by subjecting all main and branch interior surfaces to airstreams
moving at velocities two times specified working velocities, at static
pressures within maximum ratings. This may be accomplished by: filterequipped
portable blowers which remain the Contractor's property; wheelmounted,
compressed-air operated perimeter lances which direct the
compressed air and which are pulled in the direction of normal airflow; and
other means approved by the Contracting Officer. Compressed air used for
cleaning ducting shall be water- and oil- free. After construction is
complete, and prior to acceptance of the work, construction dust and debris
shall be removed from exterior surfaces. SMACNA 1987.
