.1 Before removing asbestos: .1 Prepare site. .2 Spray asbestos material with water container specified wetting agent, using airless spray equipment capable of providing application to prevent release of “mist” fibres. Saturate asbestos material sufficiently to wet it to substrate without causing excess dripping. Spray asbestos material repeatedly during work process to maintain saturation and to minimize asbestos fibre dispersion. .2 Remove any suspended ceiling and associated support system. As they are removed, pack them in sealable plastic bags 0.15mm minimum thick and place in labeled containers for transport. .3 Remove all identified asbestos. Apply continuous light misting during removal. Immediately place waste in sealable plastic bags 0.15mm minimum thick and place labeled containers for transport. .4 Remove saturated asbestos material (SFP) in small sections. Do not allow saturated asbestos to dry out. As it is being removed pack material in sealable plastic bags 0.5mm minimum thick and place in labeled containers for transport. .5 Seal filled containers. Clean external surfaces thoroughly by wet sponging. Remove from immediate working area to Staging Area. Clean external surfaces thoroughly again by wet sponging, before moving containers to decontamination Washroom. Wash containers thoroughly in decontamination Washroom, and store in Holding Room pending removal to Unloading Room and outside. Ensure that containers are removed from Holding Room, by workers who have entered from uncontaminated area dressed in clean coveralls. .6 After completion of stripping work, wire brush and wet-sponge surfaces from which asbestos has been removed, to remove visible material. During this work keep surfaces wet. .7 After wire brushing and wet sponging to remove visible asbestos, wet clean entire work area including Equipment and Access Room, and equipment used in process. After 24 hour period to allow for dust settling, wet clean these areas and objects again. During this settling period under same conditions, clean these areas and objects again using HEPA vacuum followed by wet cleaning. After inspection by Consultant apply continuous coat of slow drying sealer to surfaces of work area. Allow at least 16 hours with no entry, activity, ventilation, or disturbance other than operation of negative pressure units during this period. .8 Notify Consultant and arrange for final clearance inspection and air sampling, providing minimum 24 hours advanced notice. .9 Contractor shall forthwith rectify any deficiencies identified by the Consultant during any of the inspections at no cost to the Owner. 3.4 FINAL CLEANUP
