本指南描述了油漆清除方法、控制系统、减少或防止排放物从工作区域逸出的程序，以及评估排放控制措施充分性的程序。根据排放控制的程度，每种脱漆方法最多可将安全壳系统分为四类。本指南主要用于钢结构；然而，一些方法和材料可能适用于混凝土、铝、木材或其他建筑材料。本指南供设施所有者、规范制定者、设计师和承包商使用。其他相关方也可以使用它。当本指南在美国境外使用时，国家和地方法规可能适用。 美国。指南中包含了通风的讨论，以帮助用户控制对环境的排放，并加强安全壳内的工人保护和可见性。重要的是要认识到，当被移除的油漆含有铅或其他有毒金属时，仅通风系统可能不足以充分保护工人，并且可能需要额外的工作实践和/或行政控制和呼吸保护来控制工人的暴露。工人健康和安全的要求或评估方法不在本指南的范围内。

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 for use by facility owners, specifiers, designers, and contractors. It may also be used by other interested parties. National and local regulations may apply when this guide is used outside the U.S.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.
