(i) A Certified Lead-safe
			 Renovator-supervisor must perform a visual inspection to determine whether
			 dust, debris or residue is still present. If dust, debris or residue is
			 present, these conditions must be removed by re-cleaning and another visual
			 inspection must be performed.
(ii)
			 After a successful visual inspection, the Certified Lead-safe
			 Renovator-Supervisor must:
(A) Verify that
			 each windowsill in the work area has been adequately cleaned, using the
			 following procedure:
(1) Wipe the windowsill
			 with a wet disposable cleaning cloth that is damp to the touch. If the cloth
			 matches or is lighter than the cleaning verification card, the windowsill has
			 been adequately cleaned.
(2) If the
			 cloth does not match and is darker than the cleaning verification card,
			 re-clean the windowsill as directed at
			 454 CMR
			 22.11(9)(f), then either use
			 a new cloth or fold the used cloth in such a way that an unused surface is
			 exposed, and wipe the surface again. If the cloth matches or is lighter than
			 the cleaning verification card, that windowsill has been adequately
			 cleaned.
(3) If the cloth does not
			 match and is darker than the cleaning verification card, wait for one hour or
			 until the surface has dried completely, whichever is longer.
(4) After waiting for the windowsill to dry,
			 wipe the windowsill with a dry disposable cleaning cloth. After this wipe, the
			 windowsill has been adequately cleaned.
(B) Wipe uncarpeted floors and countertops
			 within the work area with a wet disposable cleaning cloth. Floors must be wiped
			 using an application device with a long handle and a head to which the cloth is
			 attached. The cloth must remain damp at all times while it is being used to
			 wipe the surface for post-renovation cleaning verification. If the surface
			 within the work area is greater than 40 square feet, the surface within the
			 work area must be divided into roughly equal sections that are each less than
			 40 square feet. Wipe each such section separately with a new wet disposable
			 cleaning cloth. If the cloth used to wipe each section of the surface within
			 the work area matches or is lighter than the cleaning verification card, the
			 surface has been adequately cleaned.
(1) If
			 the cloth used to wipe a particular surface section does not match the cleaning
			 verification card, re-clean that section of the surface as directed at
			 454 CMR
			 22.11(9)(f), then use a new
			 wet disposable cleaning cloth to wipe that section again. If the cloth matches
			 the cleaning verification card, that section of the surface has been adequately
			 cleaned.
(2) If the cloth used to
			 wipe a particular surface section does not match the cleaning verification card
			 after the surface has been re-cleaned, wait for one hour or until the entire
			 surface within the work area has dried completely, whichever is
			 longer.
(3) After waiting for the
			 entire surface within the work area to dry, wipe each section of the surface
			 that has not yet achieved post-renovation cleaning verification with a dry
			 disposable cleaning cloth. After this wipe, that section of the surface has
			 been adequately cleaned.
(iii) When the work area passes the
			 post-renovation cleaning verification, remove the warning
			 signs.
