    1. Scope

    1.1 This test method is applicable to the screening of cyanides in waste liquids, sludges, semisolids, and solids. The following test methods are included:

    Sections Test Method A---Chloramine T 12 through 14 Test Method B---Prussian Blue 15 through 17 Test Method C---Cyantesmo Paper 18 through 20 Test Method D---Gas Detector Tube 21 through 25

    1.2 This test method is designed and intended as a preliminary test to complement the more sophisticated quantitative analytical techniques that may be used to determine cyanide concentration. This test method offers, to the user, the option and the ability to "screen" waste for potentially hazardous levels of cyanide when the more sophisticated techniques are not available and the total waste composition is unknown.

    1.3 This standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific hazard information is given in Section 8 and 18.5.
