For example, containment materials (5.3.1) are shown as being either rigid or <br />flexible. If the specitier requires the use of rigid materials only, this restriction must be specified separately. <br />Note 3: When pressure washing is used to remove the dislodged paint, it may be necessary to specify one of the containments from Table W for the control of <br />the water and waste. <br />9-15 <br />~ ~523 <br />
