This guide describes methods of paint removal, containment systems and procedures for minimizing or preventing emissions from escaping the work area, and procedures for assessing the adequacy of the controls over emissions.
The containment systems are categorized in up to four classes per type of paint removal method, based on the extent to which emissions are controlled.
This guide is primarily intended for use with steel structures; however, some of the methods and materials may be suited for use on concrete, aluminum, wood, or other materials of construction.
This guide is intended to be used by facility owners, specifiers, designers, and contractors. It may also be used by other interested parties.
A discussion of ventilation is included in the guide to assist users in both controlling emissions to the environment, and in enhancing worker protection and visibility within the containment. It is important to recognize that ventilation systems alone may or may not be sufficient to fully protect workers when the paint being removed contains lead or other toxic metals, and additional work practice and/or administrative controls and respiratory protection may be required to control worker exposures. Requirements or evaluation methods for worker health and safety are outside the scope of this guide.
GENERAL: During surface preparation, airborne particulate and debris from the removal of paint (particularly paints containing lead, cadmium, and chromate pigments) can contaminate the air, soil, and water surrounding work sites. The potential environmental hazards are reduced by minimizing or eliminating the airborne particulate, and by containing and collecting the debris. Controlling airborne particulate and other emissions may be necessary to comply with Federal, state, and local regulations.
Procedures Included in this Guide:
• Selecting Methods of Surface Preparation and Debris Collection (Section 4.1)
• Specifying Containment Systems (Section 4.2)
• Selecting Methods for Assessing the Quantity of Emissions (Section 4.3)
• Implementing Containment Project (Section 4.4)
2.2.2 The guide also includes descriptions and commentaries on:
• Methods of Coating Removal (Section 5.1)
• Methods of Collecting Debris (Section 5.2)
• Containment Enclosure Components (Section 3)
• Ventilation System Components (Section 5.4)
• Methods for Assessing Quantity of Emissions (Section 5.5)
• Methods of Assessing Efficiency of Debris Collection and Bulk Abrasive Recovery (Section 5.)
