Pressure washing is not a prohibited practice under the Lead Renovation, Repair, and Painting (RRP) Rule. Pressure washing is subject to the same containment requirements as other permissible work practices. Before beginning the renovation, the firm must isolate the work area so that no dust or debris (including in the waste water) leaves the work area while the renovation is being performed. In addition, the firm must maintain the integrity of the containment by ensuring that any plastic or other impermeable materials are not torn or displaced and taking any other steps necessary to ensure that no dust or debris leaves the work area while the renovation is being performed. The firm must also ensure that containment is installed in such a manner that it does not interfere with occupant and worker egress in an emergency.
In addition, it is important to properly dispose of waste water used during pressure washing. Check with your local water treatment authority for more information.
