3.1 These practices and criteria were developed for occupational exposures during construction and demolition activities. They are intended to (a) protect against clinically significant disease from exposure to respirable crystalline silica, (b) be measurable by techniques that are valid, reproducible, and readily available, and (c) be attainable with existing technology and protective practices.

1.1 This practice describes several actions to reduce the risk of harmful occupational exposures in environments containing respirable crystalline silica. This practice is intended for the unique conditions during construction and demolition activities.

1.2 Health requirements relating to occupational exposure to respirable crystalline silica not covered in this practice fall under the jurisdiction of Practice E1132.

1.3 Nothing in this practice shall be interpreted as requiring any action that violates any statute or requirement of any federal, state, or other regulatory agency.

1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use.
